[[MUTCD]] specifies a standard vertically oriented signal with either two or three lenses, displaying white lines on a black background.<ref>{{MUTCD |year=2009 |revision=3 |chapter=8C}}</ref>{{rp|Fig.8C-3}}

Some systems use the letter B for buses and T for trams. The [[METRO (Minnesota)|METRO]] light rail system in [[Minneapolis, Minnesota]], the [[Valley Metro Rail]] in [[Phoenix, Arizona]]. The [[New Orleans Regional Transit Authority|RTA]] Streetcar System in [[New Orleans]] use a simplified variant of the Belgian/French system in the respective city's central business district where only the "go" and "stop" configurations are used. A third signal equal to amber is accomplished by flashing the "go" signal.
