- ATo the side of the truck where the driver's side mirror provides a clear view of the motorcycle.
- BDirectly behind the truck, where the driver can see the motorcycle in their rearview mirror.
- CIn a position where the truck driver can see the motorcyclist in a side mirror, but far enough back to allow for braking or evasive action.
- DIn the lane adjacent to the truck, slightly ahead of the truck's front bumper.
Show answer & explanationAnswer & explanation
Correct answer: C. In a position where the truck driver can see the motorcyclist in a side mirror, but far enough back to allow for braking or evasive action.
To avoid a truck's large blind spots and allow for adequate reaction time, a motorcyclist should position themselves where the truck driver can see them in a side mirror. This also requires maintaining a safe following distance to react to sudden stops or debris.
Why the other options are wrong
- A. While being visible in a side mirror is good, this option doesn't emphasize the critical component of safe following distance.
- B. Directly behind a large truck is a significant blind spot and offers no escape route or view ahead.
- D. Riding ahead of a truck's front bumper in an adjacent lane indicates passing a truck, not following it safely.
Truck Blind Spots
Large trucks have extensive blind spots (No-Zones) on all four sides. Motorcyclists must position themselves to be visible in the truck's mirrors and maintain a safe following distance.
- Blind spots are directly behind, directly in front, and on both sides.
- If you can't see the truck driver in their mirror, they can't see you.
- Maintain at least a 4-second following distance in good conditions.
Memory trick: Truck No-Zones: Nothing Overlooked.
