When driving a long vehicle, you notice that the nearside rear wheels are tracking over a raised kerb during a left turn at a junction. What does this indicate about your line choice?

When driving a long vehicle, you notice that

Multiple choice — select the best answer

AYou turned too late, meaning the cab has swung too wide
BThe trailer axles are overloaded, causing excess tyre deflection
CThe fifth wheel is incorrectly set too far forward
DYou turned too early, causing the trailer to cut in

✓ Correct answer: D. You turned too early, causing the trailer to cut in Turning the steering too early on a left bend reduces the arc available to the trailer wheels, causing the rear to cut inward and mount the kerb — the correct technique is to delay the turn and take a wider initial line.
