Question 4397
A bus and a truck arrive at the same time at a very narrow, unsigned section of road. Which vehicle must back up?
- The bus.
- The truck.
- The vehicle with the greater maximum authorized mass (MMA).
Show answer and explanation
Correct answer: The truck.
If they arrive at the same time, neither entered first, so the vehicle that has more difficulty maneuvering goes first. On the list of vehicle types, the bus ranks ahead of the truck, so the truck backs up. Maximum authorized mass does not matter here because both types are on the list.
