You are driving near a school at going-home time and see a triangular sign with a red border showing two children walking, mounted with an amber lamp above it. The amber lamp is currently flashing. What does the flashing amber lamp specifically tell you, beyond the general warning already given by the triangular sign itself?
- A crossing patrol is actively in operation at that crossing right now, so you must be ready to stop if signalled
- The flashing lamp means the school is currently closed and the crossing is not in use today
- The flashing lamp is purely decorative and adds no information beyond the triangular sign underneath it
- The flashing lamp indicates that the speed limit outside the school is temporarily reduced to 20 mph
Why A? And why not the others?
Correct answer: A. A crossing patrol is actively in operation at that crossing right now, so you must be ready to stop if signalled
The triangular sign with children walking is a standing warning that a school crossing patrol point exists on that stretch of road, but because a patrol is not necessarily present at every moment of the school day, some of these signs are fitted with an amber lamp that flashes specifically when a patrol is out and actively controlling the crossing, telling a driver they must be ready to stop the moment the patrol steps out and shows a stop sign. Claiming the flashing lamp signals school closure is wrong, since the lamp is switched on only when a patrol is working, not as a general open-or-closed indicator for the school itself. Dismissing the lamp as purely decorative misunderstands its function, since it carries a specific patrol-active signal that is absent when the lamp is unlit even though the underlying triangular warning sign remains visible at all times. Linking the lamp to a temporary 20 mph limit is also incorrect; a reduced speed limit outside a school, where one applies, is shown by its own separate numbered speed-limit signing, not by an amber lamp attached to the patrol warning sign.
