When are you required to stop for a stopped school bus with red lights flashing?

1. Only during school hours
2. Only in the evening
3. At all times ✓
4. Only during school days

Answer: C. At all times

You must stop at all times when a stopped school bus has its red lights flashing.

Why this is the answer

The truck handbook says school bus rules apply on any road, whatever the number of lanes or the speed limit, and drivers should expect to stop at any time rather than only during school hours. It also says you must stop whenever you approach a stopped school bus with its upper alternating red lights flashing, whether you are behind it or coming toward it. That makes the duty depend on the flashing red lights, not on the time of day or the school calendar.

Why the other answers are wrong

• A. Only during school hours — The rule is not limited to school hours; the handbook says to expect a school bus stop at any time.
• B. Only in the evening — There is no evening-only rule; the duty to stop depends on the bus having its red lights flashing.
• D. Only during school days — The rule is not limited to school days; it applies whenever a stopped school bus has its red lights flashing.

Remember it

Treat flashing red lights on a school bus as a stop signal that stays in force until the bus is finished.
