ATo give following drivers a clearer view of the trailer's rear lights
BTo allow the trailer's rear overhang to clear the left-hand kerb during the turn
CTo prevent the front axle from mounting the central island
DTo reduce the risk of the fifth wheel uncoupling under lateral load
✓ Correct answer: B. To allow the trailer's rear overhang to clear the left-hand kerb during the turnThe swept path of a long semi-trailer means the rear wheels cut significantly inward on a left turn; by swinging the cab rightward first, the driver increases the radius the trailer tyres follow, preventing the rear corner from mounting or striking the left-hand kerb.
