Which light requires you to stop?

A steady amber light means that vehicles must stop under the same conditions as if it were a steady red light, unless, when it comes on, the vehicle is so close to the stopping point that it cannot stop before it with sufficient safety. In contrast, a flashing amber light requires drivers to exercise extreme caution and, where necessary, to give way. It does not exempt compliance with other signals that require stopping. The green traffic light allows us to proceed with priority, unless the traffic situation is such that the vehicle would predictably come to a stop at an intersection, pedestrian crossing, or cyclist crossing, in a way that impedes or obstructs cross traffic.
