Traffic signals control the flow of traffic at intersections and crossings. This category covers standard traffic lights, arrow signals, flashing signals, and pedestrian signals.
Understanding the meaning of each signal color and type is essential. A steady green means proceed with caution, a yellow means prepare to stop, and a red means stop completely. Flashing signals have different meanings — a flashing red acts like a stop sign, while a flashing yellow means proceed with caution.
Arrow signals, lane-use signals, and pedestrian countdown timers are also commonly tested. Know when you can and cannot turn on a red light, and understand the difference between a green arrow and a circular green.
