What should the driver do when the motorcycle chain locks the rear wheel?

- Apply brakes to stop the vehicle immediately.
- Hit the brakes hard.
- Maintain control and pull over immediately. ✓
Answer: D. Maintain control and pull over immediately.
When the chain locks the rear wheel, keep the motorcycle under control and get off the road to a safe spot as soon as you can.
Why this is the answer
The handbook explains that a locked chain cannot be disengaged and will make the motorcycle skid. Because you cannot free the wheel, the only thing left to do is ride out the skid with as much control as you can and look for a safe place to leave the road. Nothing in the passage suggests working the engine or braking hard as a cure, so staying steady and pulling off is the supported response.
Why the other answers are wrong
- A. Turn off and turn on the engine. — Turning the engine off and on again does nothing about a chain that has locked the rear wheel, since the handbook says the locked chain cannot be disengaged.
- B. Apply brakes to stop the vehicle immediately. — Applying the brakes to stop immediately ignores the handbook's point that a locked wheel already makes the bike skid, so you should focus on control and finding a safe place to leave the road.
- C. Hit the brakes hard. — Hitting the brakes hard would add braking to a rear wheel that is already locked and skidding, which works against keeping control.
Remember it
A locked chain means a skidding rear wheel you can't free, so think control first and find an exit off the road.
