Zorluk: KolaySpace for Turns

When driving a large commercial vehicle that needs extra space to make a right turn at an intersection, which of the following is the correct steering technique?

  1. A
    Swing wide to the left as you approach the intersection before beginning the right turn.
  2. Keep the rear of the vehicle close to the right curb on approach and swing wide into the new street as you complete the turn.Cevap
  3. C
    Move into the oncoming traffic lane several hundred feet before the intersection to establish a wide entry angle.
  4. D
    Accelerate rapidly through the turn to minimize the time during which rear wheels off-track.

Cevap

Keep the rear of the vehicle close to the right curb on approach and swing wide into the new street as you complete the turn.
The correct method for making a right turn in a long commercial vehicle is the button-hook turn: stay close to the right curb during the approach to prevent other drivers from passing on the right, and then swing wide into the cross street only as you complete the turn.

Adım Adım Çözüm

1
Evaluate the risk of trailing traffic attempting to pass on the right side during a right turn.
Identify that leaving an open gap on the right invites smaller vehicles into the vehicle's blind spot.
Large commercial vehicles experience off-tracking, where rear wheels follow a shorter radius than front wheels.
2
Select the proper 'button-hook' turning maneuver.
Approach close to the right curb to block traffic, then turn wide into the destination street.
This prevents right-side squeeze collisions while providing sufficient clearance for trailer off-tracking.
