  1. Remain at a safe distance behind the tractor-trailer and wait until it completes the turn before proceeding.Answer
  2. B
    Squeeze into the open space on the right side of the truck to turn right before it finishes swinging left.
  3. C
    Pass the tractor-trailer on its left side while it executes the turn.
  4. D
    Move into the oncoming traffic lane to bypass the truck before it turns.

Answer

Remain at a safe distance behind the tractor-trailer and wait until it completes the turn before proceeding.
Large commercial vehicles cannot make tight right turns due to their length and trailer off-tracking. Truck drivers often swing wide to the left to clear curbs and street signs. The safest practice is to wait behind the truck until the maneuver is completed.

Step-by-Step Solution

1
Identify the heavy vehicle maneuver
Recognize that large trucks need to swing left to clear the curb when turning right.
Off-tracking causes the rear trailer wheels to follow a tighter path than the front tractor wheels.
2
Evaluate potential hazards and blind spots
Understand that the right side of the truck becomes a severe blind spot (No-Zone) during this maneuver.
The driver cannot see passenger vehicles attempting to squeeze by on the right.
3
Select the correct safe driving action
Maintain space and remain behind the truck until the intersection is clear.
Prevents squeeze-play accidents and maintains clear visual communication with the commercial driver.
