Where would you typically see a flashing red light?

A flashing red light is commonly used at railway crossings to signal to drivers that they must stop and be cautious before proceeding. This is especially important because trains can approach quickly and often require a longer stopping distance than vehicles. The flashing red light provides a clear and immediate warning to prevent accidents, emphasizing that crossing the tracks should only happen when it is safe to do so—typically when the lights are no longer flashing.

In contrast, flashing red lights at pedestrian crossings are not typical; they may indicate that pedestrians are about to cross but usually do not require vehicles to stop. At traffic lights, a flashing red would indicate the need to stop but is less common than standard red lights. Likewise, at stop signs, the signs themselves indicate where a stop is required, and flashing lights are not usually integrated into their design.
