Retrieved 8 March 2023. "Each convex mirror shall have permanently and indelibly marked at the lower edge of the mirror's reflective surface, in letters not less than 4.8 mm nor more than 6.4 mm high the words 'Objects in Mirror Are Closer Than They Appear.{{' "}}}} to be engraved on passenger side mirrors of motor vehicles in many places such as the United States, Canada, Nepal, India, and South Korea. It is present because while these mirrors' convexity gives them a useful field of view, it also makes objects appear smaller. Since smaller-appearing objects seem farther away than they actually are, a driver might make a maneuver such as a lane change assuming an adjacent vehicle is a safe distance behind, when in fact it is quite a bit closer.[http://www.physlink.com/education/AskExperts/ae449.cfm Why does the passenger side window on my car state 'objects in mirror are closer than they appear?'] Explanation from PhysLink.com.
