The Criminal Law Amendment Act, 1968–69 made it illegal to drive with a BAC in excess of 80 mg/100 mL of blood. Refusal of a police officer's demand to provide a breath sample was made an offence at the same time and both began as summary conviction offenses, with a maximum fine of up to $5000 and up to six months imprisonment.{{cite journal | author = Standing Committee on Justice and Human Rights | title = Toward Eliminating Impaired Driving — Chapter 2: Legislative Background | publisher = Parliament of Canada | date = May 1999 | url = http://cmte.parl.gc.ca/Content/HOC/committee/361/juri/reports/rp1031597/jurirp21/09-ch2-e.htm#0.2.5FPCNZ.3YC5UE.7ZN1CF.D3 | access-date = 14 April 2008 | archive-url = https://web.archive.org/web/20070709071303/http://cmte.parl.gc.ca/Content/HOC/committee/361/juri/reports/rp1031597/jurirp21/09-ch2-e.htm#0.2.5FPCNZ.3YC5UE.7ZN1CF.D3 | archive-date = 9 July 2007 | url-status = dead }}{{cite web|url=http://www.timescolonist.com/news/local/breath-test-can-t-be-refused-under-new-drunk-driving-law-1.23355573|title=Breath test can't be refused under new drunk-driving law|last=Dickson|first=Louise|website=Times Colonist|date=3 July 2018 |access-date=2019-02-04}} Many provinces have administrative penalties related to drunk driving.{{cite web|url=http://www.mto.gov.on.ca/english/safety/impaired-driving.shtml |title=Impaired driving |website=Mto.gov.on.ca |date=2019-07-12 |access-date=2022-03-01}} These penalties include immediate driver's licence suspensions and heavy fines.

• United States: Depends on state, 0.08% or 0.05% BAC by volume

Under the laws of the United States, it is unlawful to drive a motor vehicle when the ability to do so is materially impaired by the consumption of alcohol or other drugs, including prescription medications. For impaired driving charges involving the consumption of alcohol, the blood alcohol level at which impairment is presumed is 0.08, although it is possible to be convicted of impaired driving with a lower blood alcohol level.{{cite web|title=Drunken / Impaired Driving|url=http://www.ncsl.org/research/transportation/drunken-impaired-driving.aspx|website=NCSL|publisher=National Conference of State Legislatures|access-date=30 October 2017}} Some states define two impaired driving offenses.See, e.g., Cal. Vehicle Code sec. 23152(a) and (b), {{cite web|title=California Vehicle Code, Sec. 23152|url=https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=VEH§ionNum=23152.|website=California Legislative Information|publisher=California State Legislature|access-date=30 October 2017}}

1. The first is the traditional offense, variously called driving under the influence of alcohol (DUI), driving while intoxicated/impaired (DWI),See, e.g., N.Y. Vehicle and traffic law, section 1192, found at [http://public.leginfo.state.ny.us/menugetf.cgi?COMMONQUERY=LAWS New York Assembly official web site]. Go to "Bill Search and Legislative Materials", then "New York State Laws." Accessed 17 March 2008. operating under the influence (OUI), or operating while intoxicated/impaired (OWI).
2. The second and more recent is the so-called illegal per se offense of driving with a blood alcohol concentration (BAC) by volume (mass of alcohol/volume of blood) of 0.08% (previously 0.10%) or higher.

The first offense requires proof of intoxication, although evidence of BAC is admissible as rebuttably presumptive evidence of that intoxication; the second requires only proof of BAC at the time of being in physical control of a motor vehicle. An accused may potentially be convicted of both offenses as a result of a single incident, but may only be punished for one.E.g., People v. Cosko, 152 Cal. App. 3d 54, 199 Cal. Rptr. 289 (1984), citing Cal. Penal Code sec. 654 The differences between state penalties still varies. Wisconsin, for instance, is the only state that continues to treat first offense drunk driving arrests as forfeiture.Walters, Steven. "First drunken driving offense shouldn't be a crime, Van Hollen says" Milwaukee Journal Sentinel17 Jan 2009.

Some states also include a lesser charge of driving with a BAC of 0.05%; other states limit this offense to drivers under the age of 21. All states and DC also now have zero tolerance laws: the license of anyone under 21 driving with any detectable alcohol in their bloodstream (BAC limits of 0.01% or 0.02% apply in some states, such as Florida) will be suspended. In 2009, Puerto Rico joined these states, setting a limit of 0.02 for drivers under 21, despite maintaining a legal drinking age of 18.{{Cite web|url=http://www.inform.com/article/Puerto%20Rico%20OKs%20one%20lowest%20drunk-driving%20limits|archive-url=https://web.archive.org/web/20151029224040/http://inform.com/article/Puerto%20Rico%20OKs%20one%20lowest%20drunk-driving%20limits|url-status=dead|title=Puerto Rico OKs one lowest drunk-driving limits|archive-date=29 October 2015}}

The blood alcohol limit for commercial drivers is 0.04%.{{cite web|url=http://edocket.access.gpo.gov/cfr_2006/octqtr/49cfr382.201.htm|title=Alcohol concentration.|website=edocket.access.gpo.gov|access-date=16 April 2018}} Pilots of aircraft may not fly within eight hours of consuming alcohol, while under the impairing influence of alcohol or any other drug, or while showing a blood alcohol concentration equal to or greater than 0.04 grams per decilitre of blood.[http://frwebgate.access.gpo.gov/cgi-bin/get-cfr.cgi?TITLE=14&PART=91&SECTION=17&TYPE=TEXT 14 CFR 91.17], also known as Federal Air Regulation 91.17

Utah became the first U.S. state to lower the legal limit to .05% BAC by volume on 24 March 2017. The law went into effect on 30 December 2018.{{cite news|last1=Davidson|first1=Lee|title=Utahns still split on new DUI law, but big majority want changes before it kicks in|url=http://archive.sltrib.com/article.php?id=5558300&itype=CMSID|access-date=30 October 2017|newspaper=Salt Lake Tribune|date=29 July 2017}} The bill's passage, HB155, was controversial in the state. A poll published on 29 July 2017 found 50 percent of Utahns supported the new law, but 47 percent opposed it.

In most states, the timing of the chemical test for suspected drunk driving is important because the law mandates a result within a given time period after the driving stopped, usually two hours.{{citation needed|date=October 2017}}

In some states, an intoxicated person may be convicted of a DUI in a parked car if the individual is sitting behind the wheel of the car.{{cite web|title=Sleeping while drunk in the driver's seat of a parked car with the engine running is driving under the influence, and you really should have known that|url=http://www.pdsdc.org/professional-resources/criminal-law-blog/criminal-law-post/pds-criminal-law-blog/2015/01/27/sleeping-while-drunk-in-the-driver-s-seat-of-a-parked-car-with-the-engine-running-is-driving-under-the-influence-and-you-really-should-have-known-that|publisher=Public Defender Service for the District of Columbia|access-date=14 December 2017|date=22 January 2015|archive-date=2 December 2020|archive-url=https://web.archive.org/web/20201202121607/https://www.pdsdc.org/professional-resources/criminal-law-blog/criminal-law-post/pds-criminal-law-blog/2015/01/27/sleeping-while-drunk-in-the-driver-s-seat-of-a-parked-car-with-the-engine-running-is-driving-under-the-influence-and-you-really-should-have-known-that|url-status=dead}} In some jurisdictions, the occupant of a vehicle might be charged with impaired driving even if sleeping in the back seat based on proof of risk that the occupant would put the vehicle in motion while intoxicated.{{cite web|last1=Sarantis|first1=Theo|title=Drunk in the Backseat of a Car?

From 0.11%, the penalty is means tested based upon one's disposable income but at minimum a €500 fine and the withdrawal of the driver's license for at least six months, but usually about one year and in some cases, the driving licence is revoked rather than withdrawn (this penalty is set by the court and revocation means a new licence needs to be applied for after the period instated by the court). In certain states (Berlin, Bavaria, Baden-Wurttemberg) a Medical Psychological Assessment (MPU) will be ordered from 0.11% in order to be reissued with a new licence after one's revocation period and this also optionally may be ordered (at the authority's discretion) in all other states; from 0.16%, reissue of the licence requires a successful MPU.and carries a €500 fine and a minimum licence suspension of one year, but usually carries out a higher suspension as prerequisites for reissue of licences From 0.11% within ten years of an offense from 0.05%, there is a minimum €1,000 fine and a one-year license withdrawal; the driver has to successfully pass an MPU and is required to prove to the court that they have been sober for the last twelve months, before they can get their licence back. For repeat offenses, the fine is multiplied by the ordinal of the offence (doubled, tripled, etc.), regardless of the amount by which the driver was over the limit. These minimum penalties are usually exceeded by the German courts. From 0.11%, the courts usually also require the DUI offender to do unpaid community service. Note that decisions on licence reinstatement after revocation do not lie with the court but with the local administrative office for driving licenses (Verkehrsamt).

In Britain the practice is called "drink driving". In British law it is a criminal offence to be drunk in charge of a motor vehicle. The definition of "in charge" depends on such things as being in or near the vehicle, and having access to a means of starting the vehicle's engine and driving it away (i.e., the keys to a vehicle). Someone over the limit in a passenger seat can also be prosecuted if the police believe they had been driving or are able to show that there was a likelihood of them driving.{{cite web|title=In charge with excess alcohol/while unfit through drink or drugs|url=http://www.drinkdrivinglaw.co.uk/offences/in_charge_of_a_vehicle_with_excess_alcohol.htm#Can_I_be_prosecuted_if_I_am_sitting_in_the_passenger_seat|publisher=Motor Lawyers|access-date=15 February 2016}} This offence requires an objective measurement of fitness (or otherwise) to drive and is not often prosecuted.

There is also a "prescribed limit" offence of driving a motor vehicle with excess alcohol in the body above the prescribed limit. There are different prescribed limits in different jurisdictions within the United Kingdom. In England and Wales, and in Northern Ireland, the prescribed limit is 35 micrograms of alcohol per 100 millilitres of expired alveolar breath (or 80 milligrams of alcohol per 100 millilitres of blood): in Scotland, however, the prescribed limit is only just over half of this, i.e. 22 micrograms of alcohol per 100 millilitres of expired alveolar breath (or 50 milligrams of alcohol per 100 millilitres of blood).

The UK's drug driving laws were amended in 2015. The changes included a new roadside testing kit, which could detect the presence of cocaine and cannabis in a suspect's saliva and zero tolerance limits for a number of illegal drugs. Limits were also set for certain prescription medications. The laws, however, did not end the use of the field impairment test, but made them more relevant for determining driver impairment by those drugs that are not now covered by the new legislation, or cannot be identified by the limited use of a device, that currently are only authorised for cannabis and cocaine.{{cite news|last1=Waugh|first1=Rob|title=How UK's new drug-driving laws really work – as first drivers are charged|url=http://metro.co.uk/2015/05/12/how-uks-new-drug-driving-laws-really-work-as-first-drivers-are-charged-5193600/|access-date=1 August 2017|agency=Metro|date=12 May 2015}}{{cite news|last1=Adams|first1=Lucy|title=Drug-driving limits and roadside testing to be introduced|url=https://www.bbc.com/news/uk-scotland-39655137|access-date=1 August 2017|agency=BBC|date=21 April 2017}}

It is an offence to refuse to provide a specimen of breath, blood or urine for analysis. The penalties for refusing are the same as those for actual drunk driving. The request to take a screening breath test must be made by a police officer in uniform, but can only be made if one of the following situations apply:

1. the police officer has reasonable cause to suspect that the driver has committed, or is committing, a moving traffic offence, or
2. if, having stopped, an officer has reasonable cause to suspect that the person driving/attempting to drive/in charge of the vehicle has consumed alcohol, or
3. the police officer has reasonable cause to believe that the person is or was driving/attempting to drive/in charge of a motor vehicle when it was involved in an accident.{{Cite web |title=The drink drive limit |url=https://www.gov.uk/drink-drive-limit |access-date=2022-06-19 |website=GOV.UK |language=en}}

The offence of driving whilst under the influence of alcohol is one to which there is no defence, as such (although defences such as duress or automatism, which are not specific to the offence of driving with excess alcohol, may apply in certain rare circumstances). However, it may be possible to argue that special reasons exist which are such that the offender should not be disqualified from driving despite having committed the offence. Special reasons are notoriously difficult to establish, and the burden of proof is always upon the accused to establish them. Such reasons may include:

• shortness of distance driven
• unintentional commission of the offence (e.g., laced drinks)

In England and Wales, when drink driving offenders appear before a magistrates' court, the magistrates have guidelines they refer to before they decide on a suitable sentence to give the offender. These guidelines are issued by the Sentencing Guidelines Council{{cite web|url=http://www.sentencing-guidelines.gov.uk/|title=Sentencing Guidelines Council|access-date=30 March 2018|archive-url=https://web.archive.org/web/20130521173451/http://sentencing-guidelines.gov.uk/|archive-date=21 May 2013|url-status=dead|df=dmy-all}} and cover offences for which sentence is frequently imposed in a magistrates' court when dealing with adult offenders. Offences can either be tried summarily, which means they can only be heard in the magistrates' court, or they can be an "either way" offence which means magistrates may find their sentencing powers are insufficient and indict the case to a higher Crown Court. The majority of drunk driving offences are summary-only offences which can only be tried in a magistrates' court. The most serious offences, such as a collision with death or injury, must be indicted to Crown Court.

In the UK, driving or attempting to drive whilst above the legal limit of 0.08% BAC in England, Wales and Northern Ireland, and 0.05% BAC in Scotland or unfit through drink carries a maximum penalty of six months' imprisonment, a fine of up to £5,000 and a minimum twelve months' disqualification. For a second offence committed within ten years of conviction, the minimum ban is three years. Being in charge of a vehicle whilst over the legal limit or unfit through drink could result in three months' imprisonment plus a fine of up to £2,500 and a driving ban. Causing death by careless driving when under the influence of alcohol or other drugs carries a maximum penalty of fourteen years in prison, an unlimited fine, a minimum two-year driving ban, and a requirement to pass an extended driving test before the offender is able to drive legally again.{{cite web|url=https://www.gov.uk/drink-driving-penalties|title=Drink-driving penalties|website=UK GovernmentGOV.UK|access-date=16 April 2018}} In theory, the fine is means-tested and based on disposable income.{{cite web|url=http://www.drinkdrivinglaw.co.uk/drink_driving_penalties_punishments.htm|title=Drink Driving Penalties and Maximum Punishments|website=drinkdrivinglaw.co.uk|access-date=16 April 2018}} A person must be disqualified from driving post-conviction for drink driving for a minimum of 12 months, and will usually receive a fine or imprisonment.{{Cite web |title=Drink-driving penalties |url=https://www.gov.uk/drink-driving-penalties |access-date=2022-06-19 |website=GOV.UK |language=en}}

As with England and Wales, road traffic law in Scotland is in the main framed within the Road Traffic Act 1988 as amended. Prosecution and disposal of drink-drive offences is broadly similar to England and Wales with less serious cases prosecuted on complaint through the sheriff summary courts. Cases involving aggravations, life-changing or fatal injuries are prosecuted on indictment via the sheriff solemn or high court. As with most UK-wide legislation, the penalties and sentencing guidelines for drink driving in Scotland mirror those in effect in England and Wales.

• Australia: 0.05% BAC

Road laws are state or territory based, but all states and territories have set similar rules. In particular, alcohol must never exceed 0.05g of alcohol in every 100ml of blood; limits for certain categories of drivers are lower, differing in different states.

Australian laws allow police officers to stop any driver and perform a random breath test or drug test without reason. Roadblocks can be set up just about anywhere (for example, leading out of town centres on Friday and Saturday nights and after football matches or other major events), where every single driver may be randomly breath-tested. People found to have excessive alcohol or any banned substances are taken to a police station for further analysis. Those over 0.08% will receive an automatic disqualification of their licence and must appear in court.{{cite news |title=NSW Police commemorate 40th anniversary of RBT, 123 million tests and 1 million arrests later |url=https://www.drive.com.au/news/nsw-40th-anniversary-rbt-random-breath-test/ |work=Drive |date=16 December 2022 |language=en-AU}} This differs from UK and US laws where police generally need a reason to suspect that the driver is intoxicated before requesting a breath or sobriety test. It is an offence in Australia to refuse to provide a sample of breath when required to, with severe penalties, including prison.{{cite web|url=http://www.findlaw.com.au/articles/4279/can-a-person-refuse-a-breathalyser-test-and-other-.aspx |title=Can a Person Refuse a Breathalyser Test?

• 0.05% for all other drivers

• Zero for learner, provisional, truck, bus, and taxi licences
• 0.05% for all other drivers

• Zero for unlicensed drivers, holders of learner permits and probationary licences, "professional" drivers, and certain relicensed drunk-drivers.
• 0.05% for all other drivers.

There are also other restrictions for drivers in Victoria:

• Limits apply within three hours of driving - that is, police can require a person to submit to an alcohol or drugs test within three hours of driving and it is an offence to fail that test, unless the drug or alcohol use occurred after driving (see Road Safety Act 1986, ss. 49, 53 and 55E).
• Licences cancelled for certain serious drink-driving offences may only be reissued after obtaining a court order. This is the case for repeat offenders, and first offenders above 0.15%. In such cases, the relicensed driver is subject to a 0 limit for three years following relicensing, or for as long as the person is required to use an alcohol interlock.
• Alcohol interlocks must be imposed whenever a repeat drunk-driver is relicensed.
• A court also has discretion to impose an alcohol interlock when relicensing a first offender in certain serious cases, generally when the offence involves a BAC by mass of 0.15% or higher.
• The law requires interlocks to be used for certain minimum periods, but the requirement to use an interlock does not automatically end at the completion of the minimum period. Once that period has expired, an individual may apply to a court to have the interlock condition removed from their driver's licence. The State Police must be given notice of the application and may make submissions to the court on whether the interlock condition should be removed. The court will also take into account data recorded by the interlock itself (e.g., whether any attempts were made to start the vehicle by a person who had been drinking).
• Driving without an interlock when one is required carries severe penalties, including imprisonment.
• If a doctor treats any patient not under fifteen years of age as a result of a motor vehicle crash, the patient must allow the doctor to take a blood sample for testing for alcohol and drug content in a way that preserves the chain of evidence. If this process is skipped the doctor may not be able to discover the alcohol blood level. The results can be used as evidence in subsequent court proceedings.
• The law allows a police officer to require any driver (or any person who has driven a vehicle within the last three hours) to perform a random saliva test for methamphetamine, cannabis and MDMA, all of which are subject to a zero limit (per Road Safety Act 1986: ss. 49, 55E & 55D)

• Zero for learner and probationary licence-holders and persons convicted of driving under the influence or failing to comply with a request for breath, blood or urine (for three years after the offense).
• 0.05% for all other drivers.

Driving with 0.15% BAC by mass and above (legally defined as Drunk Driving) is a distinct offence from having over 0.08% but under 0.15% BAC, and is subject to heavier penalties. Persistent offenders may be barred from driving for terms up to and including life, and may be imprisoned.

The law allows a police officer to require any driver to perform a random saliva test for methamphetamine, cannabis or MDMA, all of which are subject to a zero limit.

New Zealand operates a program called Compulsory Breath Testing, which allows police to stop motorists at any time without having any reason to do so. CBT is carried out at roadside checkpoints and by mobile patrols. The police also carry out roadside drug tests upon motorists they suspect have used drugs.{{cite web |title=Alcohol and drugs limits |url=http://www.nzta.govt.nz/resources/roadcode/about-limits/alcohol-and-drugs-limits.html|publisher=New Zealand Transport Authority |access-date=1 June 2013 |location=Wellington |date=29 May 2013}}

• Zero for people under twenty years
• 0.05% BAC or 250 μg/L breath for people twenty years and over

The penalties for exceeding the limits are:

• People under twenty years, up to 0.03% BAC, 150 μg/L breath: instant NZ$200 fine and fifty demerit points
• People under twenty years, 0.03–0.08% BAC, 150–400 μg/L breath: up to three months' imprisonment, up to NZ$2,250 fine or both. Loss of license for three months or more.
• People twenty years and over, 0.051–0.08% BAC, 251–400 μg/L breath: instant NZ$200 fine and fifty demerit points. Twelve-hour prohibition from driving immediately after test.{{cite web |url=http://www.transport.govt.nz/legislation/bills/land-transport-amendment-bill-2013 |title=Land Transport Amendment Act (no 2) 2014 |work=Ministry of Transport |date=15 April 2016 |access-date=26 May 2016}}
• All people over 0.08% BAC, 400 μg/L breath (first and second offenses): up to three months' imprisonment, up to NZ$4,500 fine or both; loss of license for six months or more
• All people over 0.08% BAC, 400 μg/L breath (third and subsequent offenses): two years' imprisonment; NZ$6,000 fine; loss of license for one year or more

Drivers convicted of excess breath alcohol may be required to gain a zero-limit license.{{cn|date=October 2023}}

Note that penalties apply to the lowest reading taken across both breath and blood tests. For example, if a driver twenty years or over has a breath test result of 426 μg/L but a subsequent blood test returns 0.077% BAC, then the driver is not charged with any drink driving offense despite the breath reading being over the breath alcohol limit. The penalty for injuring or killing someone when under the influences is the same as dangerous driving (up to ten years' imprisonment, up to NZ$20,000 or both, and loss of license for one year or more).{{Cite web|url=https://www.oag.govt.nz/2013/drink-driving/appendix3.htm|title=Appendix 3: Summary of drink-driving laws|website=Office of the Auditor-General New Zealand}}
