You must stop for a school bus:
- That is parked on the shoulder of the road with no one in it.
- When it approaches you, even if its lights are not flashing.
- If you are both driving on a two-lane highway and its red lights are flashing. ✓
- Whenever the driver waves at you.
Answer: C. If you are both driving on a two-lane highway and its red lights are flashing.
You must stop when you and a school bus are driving on a two-lane highway and the bus has its red lights flashing.
Why this is the answer
The manual says that when a stopped school bus flashes its red lights, traffic coming from either direction must stop before reaching the bus, and you should stop at least 20 feet away. It also says the bus usually flashes yellow warning lights before stopping; those mean slow down and get ready to stop, not that you must stop immediately. The red flashing lights are the signal that creates the stop requirement, so a bus with flashing red lights on a two-lane highway is the situation where you must stop.
Why the other answers are wrong
- A. That is parked on the shoulder of the road with no one in it. — A bus parked on the shoulder with nobody in it is not described in the manual as requiring you to stop, especially without flashing red lights.
- B. When it approaches you, even if its lights are not flashing. — The manual says yellow warning lights mean slow down and be ready to stop; it does not require you to stop just because the bus approaches with no lights flashing.
- D. Whenever the driver waves at you. — A driver's wave is not a signal listed in the manual; the stop rule is tied to the bus's flashing red lights.
Remember it
Think red means stop for both directions; yellow means get ready, not stop yet.
