Automotive safety#Active and passive safety

{{main | Work-related road safety in the United States}}

Work-related roadway crashes are the leading cause of death from traumatic injuries in the U.S. workplace. They accounted for nearly 12,000 deaths between 1992 and 2000. Deaths and injuries from these roadway crashes result in increased costs to employers and lost productivity in addition to their toll in human suffering.{{cite journal| last = Pratt | first = Stephanie G. | title = Work-Related Roadway Crashes - Challenges and Opportunities for Prevention | website = NIOSH Hazard Review | publisher = The National Institute for Occupational Safety and Health |date=September 2003 | doi = 10.26616/NIOSHPUB2003119 | url = https://www.cdc.gov/niosh/docs/2003-119/ | access-date = 2008-11-10| archive-url= https://web.archive.org/web/20081223123756/http://www.cdc.gov/niosh/docs/2003-119/| archive-date= 23 December 2008 | url-status= live|display-authors=etal| doi-access = free }} Truck drivers tend to endure higher fatality rates than workers in other occupations, but concerns about motor vehicle safety in the workplace are not limited to those surrounding the operation of large trucks. Workers outside the motor carrier industry routinely operate company-owned vehicles for deliveries, sales and repair calls, client visits, etc. In these instances, the employer providing the vehicle generally plays a major role in setting safety, maintenance, and training policy. As in non-occupational driving, young drivers are especially at risk. In the workplace, 45% of all fatal injuries to workers under age 18 between 1992 and 2000 in the United States resulted from transportation incidents.{{cite web | last = Mardis | first = Anne L. | author2 = Stephanie G.

The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash.{{cite web|url=http://corporate.honda.com/safety/ |title=American Honda safety page |publisher=Corporate.honda.com |date=2006-03-02 |access-date=2011-09-20}}{{cite magazine |url=http://www.gladwell.com/pdf/suv.pdf |title=BIG AND BAD: How the S.U.V. ran over automotive safety |access-date=2009-07-24 |last=Gladwell |first=Malcolm |date=2004-01-12 |magazine=The New Yorker |url-status=dead |archive-url=https://web.archive.org/web/20090706042735/http://www.gladwell.com/pdf/suv.pdf |archive-date=2009-07-06 }}

{{See also|Active safety|Pre-crash system|Collision avoidance system}}

Crash avoidance systems and devices help the driver — and, increasingly, help the vehicle itself — to avoid a collision. This category includes:

• The vehicle's headlamps, reflectors, and other lights and signals
• The vehicle's mirrors
• The vehicle's brakes, steering, and suspension systems

A subset of crash avoidance is driver assistance systems, which help the driver to detect obstacles and to control the vehicle. Driver assistance systems include:

• Driver Alertness Detection System (DADS) to help prevent crashes caused by fatigue, lack of alertness, or distractions{{cite web |url=https://www.sleepreviewmag.com/sleep-treatments/therapy-devices/emerging-technology/intercore-driver-alertness-detection-system-dads/ |title=InterCore's Driver Alertness Detection System (DADS) |last=Roy |first=Sree |date=17 December 2014 |website=Sleep Review |access-date=6 March 2021}}
• Advanced emergency braking system systems to prevent or reduce the severity of collision.
• Infrared night vision systems to increase seeing distance beyond headlamp range
• Adaptive headlamps control the direction and range of the headlight beams to light the driver's way through curves and maximize seeing distance without partially blinding other drivers
• Reverse backup sensors, which alert drivers to difficult-to-see objects in their path when reversing
• Backup camera
• Adaptive cruise control which maintains a safe distance from the vehicle in front
• Lane departure warning systems to alert the driver of an unintended departure from the intended lane of travel
• Tire pressure monitoring systems or Deflation Detection Systems
• Traction control systems which restore traction if driven wheels begin to spin
• Electronic Stability Control, which intervenes to avert an impending loss of control
• Anti-lock braking systems
• Electronic brakeforce distribution systems
• Emergency brake assist systems
• Cornering Brake Control systems
• Assured Clear Distance Ahead measurement and speed governance systems
• Precrash system
• Automated parking system
• Obstacle detection sensor systems notify a driver how close their vehicle is to an object - usually providing a distance measurement, to the inch, as to how close they are.

Crashworthy systems and devices prevent or reduce the severity of injuries when a crash is imminent or actually happening. Much research is carried out using anthropomorphic crash test dummies.

• Seatbelts limit the forward motion of an occupant, stretch to absorb energy, to lengthen the time of the occupant's negative acceleration in a crash, reducing the loading on the occupants' body. They prevent occupants being ejected from the vehicle and ensure that they are in the correct position for the operation of the airbags.
• Airbags inflate to cushion the impact of a vehicle occupant with various parts of the vehicle's interior. The most important being the prevention of direct impact of the driver's head with the steering wheel and door pillar.
• Laminated windshields remain in one piece when impacted, preventing penetration of unbelted occupants' heads and maintaining a minimal but adequate transparency for control of the car immediately following a collision. It is also a bonded structural part of the safety cell. Tempered glass side and rear windows break into granules with minimally sharp edges, rather than splintering into jagged fragments as ordinary glass does.
• Crumple zones absorb and dissipate the force of a collision, displacing and diverting it away from the passenger compartment and reducing the negative acceleration impact force on the vehicle occupants. Vehicles will include a front, rear and maybe side crumple zones (like Volvo SIPS) too.
• Safety Cell—the passenger compartment is reinforced with high strength materials, at places subject to high loads in a crash, in order to maintain a survival space for the vehicle occupants. Footwell intrusion is one recognized failure mode of the safety cell, and anti-intrusion bars are one component addressing protection in side impacts.
• Collapsible universally jointed steering columns, along with steering wheel airbag. The steering system is mounted behind the front axle - behind and protected by, the front crumple zone. This reduces the risk and severity of driver impact or even impalement on the column in a frontal crash.
• Pedestrian protection systems.
• Padding of the instrument panel and other interior parts, on the vehicle in areas likely to be struck by the occupants during a crash, and the careful placement of mounting brackets away from those areas.
• Cargo barriers are sometimes fitted to provide a physical barrier between passenger and cargo compartments in vehicles such as SUVs, station wagons and vans. These help prevent injuries caused by occupants being struck by unsecured cargo. They can also help prevent collapse of the roof in the event of a vehicle rollover.

Post-crash survivability is the chance that drivers and passengers survive a crash after it occurs. Technology such as Advanced Automatic Collision Notification can automatically place calls to emergency services and send information about a vehicle collision.

Vehicles are equipped with a variety of lights and reflectors to mark their presence, position, width, length, and direction of travel as well as to convey the driver's intent and actions to other drivers. These include the vehicle's headlamps, front and rear position lamps, side marker lights and reflectors, turn signals, stop (brake) lamps, and reversing lamps. School buses and semi-trailer trucks in North America are required to bear retroreflective strips outlining their side and rear perimeters for greater conspicuity at night.{{cite web |url=http://www.nhtsa.gov/cars/rules/regrev/evaluate/809222.html |title=The Effectiveness of Retroreflective Tape on Heavy Trailers |publisher=Nhtsa.gov |access-date=2011-09-20 |archive-date=2016-11-24 |archive-url=https://web.archive.org/web/20161124222541/http://www.nhtsa.gov/cars/rules/regrev/evaluate/809222.html |url-status=dead }}

Daytime running lamps have been required in the Nordic countries since the mid-1970s, in Canada since 1990, and throughout the European Union since 7 February 2011.{{cite web|url=http://europa.eu/rapid/pressReleasesAction.do?reference=IP/11/133&type=HTML |title=Press Release "New cars equipped with daytime running lights as of today" |publisher=Europa.eu |date=2011-02-07 |access-date=2011-09-20}}{{cite web|url=http://www.drivingvisionnews.com/news/lighting/78-regulations/2858-drl-mandate-takes-effect-in-europe-r48-countries- |title=DRL Mandate Takes Effect in Europe, R48 Countries |publisher=Drivingvisionnews.com |access-date=2011-09-20}}

A 2004 essay on the relation between car colour and safety stated that no previous studies had been scientifically conclusive.{{cite web | url=http://www.aaafoundation.org/pdf/CarColorAndSafety.pdf | title=Car Color and Safety | publisher=AAA Foundation | access-date=2012-03-20 | archive-url=https://web.archive.org/web/20120504013912/http://www.aaafoundation.org/pdf/CarColorAndSafety.pdf | archive-date=2012-05-04 | url-status=dead }} Since then, a Swedish study found that pink cars are involved in the fewest and black cars are involved in the most crashes (Land transport NZ 2005). In Auckland New Zealand, a study found that there was a significantly lower rate of serious injury in silver cars, with higher rates in brown, black, and green cars. The Vehicle Colour Study, conducted by Monash University Accident Research Centre (MUARC) and published in 2007, analysed 855,258 crashes that occurring between 1987 and 2004 in the Australian states of Victoria and Western Australia that resulted in injury or in a vehicle being towed away.{{cite web |url=http://www.monash.edu.au/muarc/reports/muarc263.pdf |title=An Investigation into the Relationship between Vehicle Colour and Crash Risk |access-date=2011-09-20 |url-status=dead |archive-url=https://web.archive.org/web/20110607062614/http://www.monash.edu.au/muarc/reports/muarc263.pdf |archive-date=2011-06-07 }} The study analysed risk by light condition. It found that in daylight, black cars were 12% more likely than white to be involved in a collision, followed by grey cars at 11%, silver cars at 10%, and red and blue cars at 7%, with no other colours found to be significantly more or less risky than white. At dawn or dusk, the risk ratio for black cars jumped to 47% more likely than white, and that for silver cars to 15%. In the hours of darkness, only red and silver cars were found to be significantly more risky than white, by 10% and 8% respectively.{{citation needed|date=April 2016}}

Many different inventions and ideas which may or may not have been practical about auto safety have been put forward but never made it to a production car. Such items include the driver seat in the middle (to give the person a better view){{cite journal|title=Popular Science|journal=The Popular Science Monthly|publisher=Bonnier Corporation|issn=0161-7370|url=https://archive.org/details/bub_gb_6CkDAAAAMBAJ|page=[https://archive.org/details/bub_gb_6CkDAAAAMBAJ/page/n95 94]|access-date=2014-12-12|date=December 1956}} (the exception being the McLaren F1 super car) and control stick steering.{{citation needed|date=April 2016}}

Automotive safety may have become an issue almost from the beginning of mechanised road vehicle development. The second steam-powered "Fardier" (artillery tractor), created by Nicolas-Joseph Cugnot in 1771, is reported by some to have crashed into a wall during its demonstration run. However, according to Georges Ageon,{{cite web|title=Le fardier de Cugnot |url=http://www.ile-de-france.drire.gouv.fr/vehicules/homolo/cnrv/histoire.htm |url-status=dead |archive-url=https://web.archive.org/web/20080416231439/http://www.ile-de-france.drire.gouv.fr/vehicules/homolo/cnrv/histoire.htm |archive-date=2008-04-16 }} the earliest mention of this occurrence dates from 1801 and it does not feature in contemporary accounts. One of the earliest recorded car-related fatalities was Mary Ward, on August 31, 1869, in Parsonstown, Ireland.{{cite web|url=http://www.universityscience.ie/pages/scientists/sci_mary_ward.php |title=Mary Ward 1827–1869 |url-status=dead |archive-url=https://web.archive.org/web/20080311122721/http://www.universityscience.ie/pages/scientists/sci_mary_ward.php |archive-date=2008-03-11 }}

In 1955, a USAF surgeon who advised the US Surgeon General wrote an article on how to make cars safer for those riding in it. Aside from the usual safety features, such as seat belts and padded dashboards, bumper shocks were introduced.[https://books.google.com/books?id=biYDAAAAMBAJ&pg=-PA27 "Safer Cars."] Popular Science, June 1955, pp. 27-30/252

In 1956, Ford tried unsuccessfully to interest Americans in purchasing safer cars with their Lifeguard safety package. (Its attempt nevertheless earns Ford Motor Trend{{'}}s "Car of the Year" award for 1956.)Flory, J. "Kelly", Jr. American Cars 1946–1959 (Jefferson, NC: McFarland & Coy, 2008), p.701.

In 1958, the United Nations established the World Forum for Harmonization of Vehicle Regulations, an international standards body advancing auto safety. Many of the most life saving safety innovations, like seat belts and roll cage construction were brought to market under its auspices. That same year, Volvo engineer Nils Bohlin invented and patented the three-point lap and shoulder seat belt, which became standard equipment on all Volvo cars in 1959.{{Cite web|url=http://www.volvocars.com/intl/about/our-company/heritage/innovations |title=Safety Innovation in Cars |website=volvocars.com |access-date=2016-11-12|archive-url=https://web.archive.org/web/20161113114437/http://www.volvocars.com/intl/about/our-company/heritage/innovations|archive-date=2016-11-13|url-status=dead}} Over the next several decades, three-point safety belts were gradually mandated in all vehicles by regulators throughout the industrialised world.{{citation needed|date=April 2016}}

On September 9, 1966, the National Traffic and Motor Vehicle Safety Act became law in the U.S., the first mandatory federal safety standards for motor vehicles.{{cite book |last=Hendrickson |first=Kimberly A. |chapter=National Traffic and Motor Vehicle Safety Act |title=Dictionary of American History |editor-first=Stanley I. |editor-last=Kutler |edition=3rd |volume=5 |publisher=Charles Scribner's Sons |year=2003 |pages=561–562 |chapter-url=http://go.galegroup.com/ps/i.do?id=GALE%7CCX3401802875&v=2.1&it=r&p=GVRL&sw=w&asid=73b32300d98b9c9749355917ffb94b15 |quote=Signed into law by President Lyndon Johnson on 9 September 1966, this act created the first mandatory federal safety standards for motor vehicles.}}

Effective in 1966, US-market passenger cars were required to be equipped with padded instrument panels, front and rear outboard lap belts, and white reverse (backup) lamps.{{citation needed|date=April 2016}}

In 1966, the U.S. established the United States Department of Transportation (DOT) with automobile safety as one of its purposes. The National Transportation Safety Board (NTSB) was created as an independent organization on April 1, 1967, but was reliant on the DOT for administration and funding. However, in 1975 the organization was made completely independent by the Independent Safety Board Act (in P.L. 93-633; 49 U.S.C. 1901).{{citation needed|date=April 2016}}

In 1967, equipment specifications by such major fleet purchasers as the City and County of Los Angeles, California, encouraged the voluntary installation in most new cars sold in the US of safety devices, systems, and design features including:{{cite news|url=http://www.ijcrt.org/papers/IJCRT1801132.pdf|title=Safety and Security in Automobile and Its History|last=Dharam Pal|first= Kashyap|publisher=2017 International Journal of Creative Research Thoughts, Volume 5, Issue 1 }}

• Elimination of protruding knobs and controls in passenger compartment
• Additional padding on the instrument panel and other interior surfaces
• Mounting points for front outboard shoulder belts
• Four-way hazard flashers
• A uniform P-R-N-D-L gear sequence for automatic transmission gear selectors
• Dual-circuit brake hydraulic systems

In 1968, the precursor agency to the US National Highway Traffic Safety Administration's first Federal Motor Vehicle Safety Standards took effect. These required shoulder belts for left and right front-seat vehicle occupants, side marker lights, collapsible steering columns, and other safety features. 1969 saw the addition of head restraints for front outboard passengers, addressing the problem of whiplash in rear-end collisions. These safety requirements did not apply to vehicles classified as "commercial," such as light-duty pickup trucks. Thus, manufacturers did not always include such hardware in these vehicles, even though many did passenger-car duty.{{Citation needed|date=July 2012}}

In 1976, the crash test dummy Hybrid III was introduced to assess the impacts of car collisions. It represented the 50th percentile male standing at approximately 5' 9" tall and weighing 78 kg (171 lbs).{{Cite web |last=Epker |first=Eva |title=Fasten Your Seatbelts: A Female Car Crash Test Dummy Represents Average Women For The First Time In 60+ Years |url=https://www.forbes.com/sites/evaepker/2023/09/12/fasten-your-seatbelts-a-female-car-crash-test-dummy-represents-average-women-for-the-first-time-in-60-years/ |access-date=2024-04-08 |website=Forbes |language=en}}

In 1979, NHTSA began crash-testing popular cars and publishing the results, to inform consumers and encourage manufacturers to improve the safety of their vehicles. Initially, the US NCAP (New Car Assessment Program) crash tests examined compliance with the occupant-protection provisions of FMVSS 208. Over the subsequent years, this NHTSA program was gradually expanded in scope.

In 1984, New York State passed the first U.S. law requiring seat belt use in passenger cars. Seat belt laws have since been adopted by 49 states (New Hampshire has not).{{cite web|url=http://www.iihs.org/iihs/topics/laws/safetybeltuse?topicName=safety-belts |title=Safety belt and child restraint laws |publisher=Insurance Institute for Highway Safety |date = March 2018}} NHTSA estimates the resulting increased seat belt use saves 10,000 per year in the United States.{{cite web|url=https://one.nhtsa.gov/people/injury/research/BuckleUp/ii__trends.htm |title=Trends in Occupant Restraint Use and Fatalities |website =NHTSA|publisher = US Department of Transportation }}

Airbags were first installed in production vehicles in the 1980s as standard equipment instead of an option as was done in the mid-1970s (such as the Oldsmobile Toronado in 1974{{cite web|url = https://www.thoughtco.com/history-of-airbags-1991232|title = The History of Airbags|last = Bellis|first = Mary|website = ThoughtCo.|date = 22 January 2018}}{{cite web |url = https://www.consumeraffairs.com/news04/2006/airbags/airbags_invented.html |title = A Short History of the Airbag|author = Lisa Wade McCormick|date = 25 September 2006|website = Consumer Affairs}}). In 1981, airbags were an available option on the Mercedes-Benz W126 (S-Class). In 1987, the Porsche 944 Turbo became the first car to have driver and passenger airbags as standard equipment, and airbags were offered as an available option on the 944 and 944S.

Research on the trends in use of heavy vehicles indicate that a significant difference between the US and other countries is the relatively high prevalence of pickup trucks and SUVs in the US. A 2003 study by the US Transportation Research Board found that SUVs and pickup trucks are significantly less safe than passenger cars, that non-US branded vehicles tend to be safer than US branded vehicles, and that the size and weight of a vehicle has a significantly smaller effect on safety than the quality of the vehicle's engineering.{{Cite web

Nevertheless, the widespread use of truck-based vehicles as passenger carriers is correlated with roadway deaths and injuries not only directly by dint of vehicular safety performance per se, but also indirectly through the relatively low fuel costs that facilitate the use of such vehicles in North America; motor vehicle fatalities decline as fuel prices increase.{{Cite journal |doi=10.1002/pam.20028 |title=Gasoline prices and motor vehicle fatalities |journal=Journal of Policy Analysis and Management |volume=23 |issue=3 |pages=575–593 |year=2004 |last1=Grabowski |first1=David C |last2=Morrisey |first2=Michael A }}

The US NHTSA has issued relatively few regulations since the mid-1980s; most of the vehicle-based reduction in vehicle fatality rates in the US during the last third of the 20th Century were gained by the initial NHTSA safety standards issued from 1968 to 1984 and subsequent voluntary changes in vehicle design and construction by vehicle manufacturers.{{Cite book

When pregnant, women should continue to use seatbelts and airbags properly. A University of Michigan study found that "unrestrained or improperly restrained pregnant women are 5.7 times more likely to have an adverse fetal outcome than properly restrained pregnant women".{{cite web|url=http://www.dps.state.mn.us/trafsafe/beltsairbags/pregnacy.htm |title=Wearing a seat belt during pregnancy - Minnesota Department of Public Safety |access-date=2014-12-12 |url-status=dead |archive-url=https://web.archive.org/web/20040623184946/http://www.dps.state.mn.us/trafsafe/beltsairbags/pregnacy.htm |archive-date=June 23, 2004 }} If seatbelts are not long enough, extensions are available from the car manufacturer or an aftermarket supplier.{{citation needed|date=April 2016}}

Children present significant challenges in engineering and producing safe vehicles, because most children are significantly smaller and lighter than most adults. Additionally, children far from being just scaled down adults, still have an undeveloped skeletal system. This means that vehicle restraint systems such as airbags and seat belts, far from being effective, are hazardous if used to restrain young children. In recognition of this, many medical professionals and jurisdictions recommend or require that children under a particular age, height, and/or weight ride in a child seat and/or in the back seat, as applicable.{{citation needed|date=April 2016}}

Within Europe ECE Regulation R44 dictates that children below 150 cm must travel in a child restraint that is appropriate for their weight. Each country have their own adaptions of this Regulation. For instance, in the United Kingdom, children must travel in a child restraint until they are 135 cm tall or reach 12 years of age, which ever comes soonest. As another example, in Austria, the driver of passenger vehicles is responsible for people shorter than 150 cm and below 14 years to be seated in an adequate child safety seat. Moreover, it is not allowed for children below the age of 3 to ride in a passenger vehicle without "security system" (which in practice means the vehicle is not equipped with any seat belts or technical systems like Isofix), whereas children between 3 and 14 years have to ride in the back seat.

In the UK, a full driving licence can be had at age 17, and most areas in the United States will issue a full driver's license at the age of 16, and all within a range between 14 and 18.{{cite web|url=http://golocalnet.com/drivingage/|title=Driving in other states|website=golocalnet.com|access-date=2006-08-31|archive-date=2021-11-04|archive-url=https://web.archive.org/web/20211104214835/https://www.golocalnet.com/drivingage/|url-status=dead}} In addition to being relatively inexperienced, teen drivers are also cognitively immature, compared to adult drivers.{{cite news|url=https://www.washingtonpost.com/wp-dyn/articles/A52687-2005Jan31.html |title=Brain Immaturity Could Explain Teen Crash Rate |newspaper =Washington Post |date=1 February 2005 |first = Elizabeth|last = Williamson}} This combination leads to a relatively high crash rate among this demographic.

In some areas, new drivers' vehicles must bear a warning sign to alert other drivers that the vehicle is being driven by an inexperienced and learning driver, giving them opportunity to be more cautious and to encourage other drivers to give novices more leeway.{{Cite web|url=https://www.servicenl.gov.nl.ca |archive-url=https://web.archive.org/web/20070417000447/http://www.gs.gov.nl.ca/gs/mr/dl-graduated-driver.stm |url-status=dead |title=Service NL |archive-date=April 17, 2007 |website=servicenl.gov.nl.ca}} In the U.S. New Jersey has Kyleigh's Law citing that teen drivers must have a decal on their vehicle.{{cite web|url=http://www.njteendriving.com/ |title=Kyleigh's Law, GDL, Driver Education, Crash Maps, Videos, Safety Tips & more... | New Jersey Teen Driving |publisher=Njteendriving.com |access-date=2011-09-20}}

Some countries, such as Australia, the United States, Canada and New Zealand, have graduated levels of driver's licence, with special rules.{{cite web|url=http://163.189.7.150/licensing/gettingalicence/car/provisional_licence.html?llid=2|title=Licence|website=Roads and Maritime Services|access-date=2008-03-05|archive-url=https://web.archive.org/web/20080302223458/http://163.189.7.150/licensing/gettingalicence/car/provisional_licence.html?llid=2|archive-date=2008-03-02|url-status=dead}} By 2010, all US states required a graduated driver's licence for drivers under age 18. In Italy, the maximum speed and power of vehicles driven by new drivers is restricted. In Romania, the maximum speed of vehicles driven by new drivers (less than one year in experience) is 20 km/h lower than the national standard (except villages, towns and cities). Many U.S. states allow 18-year-olds to skip some requirements that younger drivers would face, which statistics show may be causing higher crash rates among new drivers. New Jersey has the same requirements for new drivers up to the age of 21, which may obviate this problem.{{cite web |url=https://www.npr.org/blogs/health/2011/09/14/140433369/-fatal-car-crashes-drop-for-16-year-olds-rise-for-older-teens |title=Fatal Car Crashes Drop For 16-Year-Olds, Rise For Older Teens |first=Allison |last=Aubrey |date=September 14, 2011 |website=Shots - NPR's Health Blog |publisher=NPR |location=Washington, DC |archive-url=https://web.archive.org/web/20111107180044/http://www.npr.org/blogs/health/2011/09/14/140433369/-fatal-car-crashes-drop-for-16-year-olds-rise-for-older-teens |archive-date=2011-11-07 |access-date=2011-11-07 |url-status=bot: unknown }}

According to a study{{Cite journal|url=https://www.mayoclinicproceedings.org/article/S0025-6196(17)30433-0/fulltext |title=Comparison of Unsafe Driving Across Medical Conditions |first1=Hannes|last1=Devos |first2=Abiodun E.|last2=Akinwuntan |first3=Mark|last3=Tant |first4=Maud|last4=Ranchet |first5=Sanghee|last5=Moon |date=September 1, 2017 |journal=Mayo Clinic Proceedings |volume=92|issue=9 |pages=1341–1350 |via=mayoclinicproceedings.org |doi=10.1016/j.mayocp.2017.06.003 |pmid=28870353}} published in 2017 in the Mayo Clinic Proceedings, although most drivers with medical conditions were safe drivers, drivers with psychiatric conditions or substance abuse were particularly at higher risks of unsafe driving. The study also reported that drivers with neurological conditions were the majority of the entire study population (Belgium) who were referred for a driving evaluation, but they were not the most unsafe drivers.

Insurance statistics in the United States indicate a 30% increase in the number of elderly killed, comparing 1975 to 2000.{{cite web |url=https://www.pbs.org/newshour/bb/transportation/july-dec01/drivers_8-14.html |title=Online NewsHour: Elderly Drivers - August 14, 2001 |publisher=Pbs.org |date=2001-08-14 |access-date=2011-09-20 |archive-date=2013-04-02 |archive-url=https://web.archive.org/web/20130402083108/http://www.pbs.org/newshour/bb/transportation/july-dec01/drivers_8-14.html |url-status=dead }}

Several states require additional testing for elderly drivers. On a per-driver basis, the number of fatal and overall crashes decreases with age, with some exceptions for drivers over 75.{{cite web|url=http://www.allcountries.org/uscensus/1045_age_of_driver_and_number_in.html |title=Age of Driver and Number in Accidents statistics - USA Census numbers |publisher=Allcountries.org |access-date=2011-09-20}} The overall trend may be due to greater experience and avoiding driving in adverse conditions. However, on a per-miles-travelled basis,{{cite web|url=http://www.senatormoore.com/issues/indepth/seniors/resources/Elderly%20Drivers%20Research.pdf|archive-url=https://web.archive.org/web/20091229125408/http://www.senatormoore.com/issues/indepth/seniors/resources/Elderly%20Drivers%20Research.pdf|url-status=dead|archive-date=29 December 2009|date=19 August 2009|title=Elderly Driving Statistics and Motor Vehicle Operation Laws|access-date=2014-12-12}} drivers younger than 25-30 and older than 65-70 have significantly higher crash rates. Survivability of crashes decreases monotonically with the age of the victim.

A common problem for the elderly is the question of when a medical condition or biological aging presents a serious enough problem that one should stop driving. In some cases, this means giving up some personal independence, but in urban areas often means relying more on public transportation. Many transit systems offer discounted fares to seniors,{{cite web |title=Reduced Fare Program |url=https://www.mywaythere.org/reducedfare.asp#:~:text=The%20Universal%20Reduced%20Fare%20program,for%20people%20on%20limited%20incomes. |website=My Way There |access-date=20 June 2020}} and some local governments run "senior shuttles" specifically targeted at this demographic.{{cite web |title=Service |url=https://www.seniorshuttleservice.com/service |website=Senior Shuttle Plus |access-date=20 June 2020}}

While it is usually considered that the driver has the responsibility when collisions occur, vehicle can also contribute to collisions, up to 3% to 5% of crashes.{{cite web|url=http://toolkit.irap.org/default.asp?page=treatment&id=53|title=Research in developed countries suggests that vehicle defects cause about 3% to 5% of crashes|website=IRAP Road Safety Toolkit|archive-url=https://web.archive.org/web/20100507125933/http://toolkit.irap.org/default.asp?page=treatment&id=53|archive-date=May 7, 2010}}

Two kinds of programs exist: new car assessment program for new cars, and vehicle inspections for other ones.

File:NCAPLabel.jpg

A New Car Assessment Program is a government or institutional car safety program tasked with evaluating new car designs for performance against various safety threats.

Two well known NCAP are United States New Car Assessment Program since 1978 and European New Car Assessment Programme since 1997.

Vehicle inspection is a procedure mandated by national or subnational governments in many countries, in which a vehicle is inspected to ensure that it conforms to regulations governing safety, emissions, or both. Inspection can be required at various times, e.g., periodically or on the transfer of title to a vehicle.

If required periodically, it might be termed periodic motor vehicle inspection, or MOT test in the UK, or roadworthiness test in EU directives. Typical intervals are every two years (in EU) and every year (in UK). When a vehicle passes inspection, often a sticker is placed on the vehicle's windshield or registration plate to simplify later controls, but in some countries (such as Netherlands since 1994) this is no longer necessary.

Vehicles are tested at inspection stations when due for inspection. Most US inspection decals/stickers display the month's number and the year. They are called testing centre in EU directives.

Vehicle inspection exists in the United States.

In Victoria, Australia, safety features checked include the structure of the vehicle, the tires (depth of tread), the wheels, the engine, steering, suspension, brakes, and lights and seatbelts.

Tires should be checked regularly.{{Cite web|url=https://www.preferredmutual.com/info/library/auto-insurance/are-your-tires-ready-for-winter |title=How to Check if Your Tires Are Safe for Driving this Winter Season |website=preferredmutual.com}}

Tire checking is important, because proper contact between tire and road is required for adequate vehicle control.{{Cite web|url=https://www.rac.co.uk/drive/advice/tyres/checking-tyre-tread |title=Tyre tread depth and tyre safety checks | RAC Drive |website=rac.co.uk}}
