Question: Why is it particularly dangerous for a commercial vehicle to make a right turn when a pedestrian is waiting at the crosswalk on the right side?

Answer options:

  • The pedestrian might distract the driver at the last moment. ✅ The off-tracking of the trailer can sweep the pedestrian off the curb or into the turn.
  • Commercial vehicles have slower acceleration and may block the crosswalk for too long.
  • The noise of the truck engine might startle the pedestrian.

Correct answer: The off-tracking of the trailer can sweep the pedestrian off the curb or into the turn.

Explanation: During a right turn, the trailer of a large commercial vehicle will off-track, meaning it will cut a tighter path than the tractor. This creates a significant hazard in the 'sweep path' of the trailer, potentially hitting pedestrians, cyclists, or objects near the curb.
