<P> At intersections where U-turns are permitted and controlled by a U-turn arrow from the left-most lane, motorists turning right on red onto the same road must yield to those making U-turns before turning, as the motorists making U-turns have the right of way and a collision could easily occur . At intersections where U-turns are prohibited in the same fashion, a green right turn arrow will sometimes appear with the red light for those turning right onto the road, allowing only traffic turning right to proceed without having to stop or yield to other vehicles or pedestrians . Some states such as California have "No U-Turn" signs posted at these intersections because of the green right turn arrow . </P> <P> Most Caribbean countries with right - hand traffic, such as the Dominican Republic, allow right turn on red unless a sign prohibits it . Some vehicles, such as those carrying hazardous materials and school buses, are not allowed to turn on red under any circumstance and must wait for a green light or arrow . </P> <P> During 1982--1992, approximately 84 fatal crashes per year occurred in the U.S. where a vehicle was turning right at intersections where right turn on red was permitted . As of 1992, right turn on red is governed federally by 42 U.S.C. § 6322 (c) ("Each proposed State energy conservation plan to be eligible for Federal assistance under this part shall include:...(5) a traffic law or regulation which, to the maximum extent practicable consistent with safety, permits the operator of a motor vehicle to turn such vehicle right at a red stop light after stopping, and to turn such vehicle left from a one - way street onto a one - way street at a red light after stopping ."). All turns on red are forbidden in New York City unless a sign is posted permitting it . </P> <P> Through most of Canada, a driver may turn right at a red light after coming to a complete stop unless a sign indicates otherwise . In the province of Quebec, turning right on a red was illegal until a pilot study carried out in 2003 showed that the right turn on red manoeuvre did not result in significantly more accidents . Subsequent to the study, the Province of Quebec now allows right turns on red except where prohibited by a sign . However, like in New York City, it remains illegal to turn right on a red anywhere on the Island of Montreal . Motorists are reminded of this by large signs posted at the entrance to all bridges . </P>
