Which vehicles must stop at all railroad crossings?
- Pick-up trucks
- School buses and occupied passenger buses ✓
- Motorcycles
- Vehicles towing a trailer
Answer: B. School buses and occupied passenger buses
School buses and passenger buses with people on board must stop at all railroad crossings.
Why this is the answer
The manual's railroad-crossing section lists the vehicles that must stop every time: school buses whether or not they carry passengers, other buses that have passengers on board, and vehicles carrying explosives or flammable cargo. That is why the choice naming school buses and occupied passenger buses is correct. The rule depends on the type of vehicle and, for non-school buses, whether passengers are aboard. The passage also tells drivers following such a vehicle to remember these stopping rules.
Why the other answers are wrong
- A. Pick-up trucks — Pick-up trucks are not included in the manual's list of vehicles that must stop at every railroad crossing.
- C. Motorcycles — Motorcycles are not named in that list, so the all-crossing stopping rule does not apply to them here.
- D. Vehicles towing a trailer — A vehicle towing a trailer is not part of the stated list; the manual names buses with passengers and vehicles with explosives or flammable cargo, not trailers.
Remember it
Remember the passenger rule: school bus always, other bus only when people are on board.
