  1. Remain behind the truck at a safe distance and wait until it completes the turn.Answer
  2. B
    Pass the truck on its right side using the open space created when it swung left.
  3. C
    Drive onto the right shoulder to bypass the truck before it turns.
  4. D
    Accelerate quickly into the left lane beside the truck to pass before it turns right.

Answer

Remain behind the truck at a safe distance and wait until it completes the turn.
Large commercial trucks require extra room to negotiate right turns without running rear wheels over curbs or street fixtures. To do this, truck drivers must often swing wide into the left lane first. The safest procedure for following drivers is to stay back and wait until the truck finishes turning.

Step-by-Step Solution

1
Analyze the truck's turn signal and roadway position
Identify that the truck is preparing for a wide right turn by swinging left to clear the curb.
Commercial vehicles have longer wheelbases and off-tracking rear wheels that require wider turns.
2
Evaluate the blind spot risk
Recognize that the area to the right of a turning truck is a major No-Zone where the truck driver cannot see other vehicles.
If you cannot see the truck's side mirrors, the truck driver cannot see your vehicle.
3
Select the appropriate defensive driving response
Hold position behind the truck until the intersection is clear.
Waiting allows the truck driver the necessary room to complete the turn without risking a squeeze collision.
