where is the green light on a traffic light
Traffic light Aspect is a term referring to the light that faces the drivers. A typical vertical traffic signal has three aspects, or lights, facing the oncoming traffic, red on top, yellow below, and green below that. Generally one aspect is illuminated at a time. In some cases, a fourth aspect, for a turn arrow for example, is below the three lights or aspects in more complicated road traffic intersections.
Turn on red 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.[citation needed] 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.[6]
