Question 100 of 120

Why should lane changes be planned further in advance when driving a triples combination compared to a single trailer?

Pick an answer

The combination's greater length takes longer to fully clear a lane, and abrupt movements can trigger rearward amplification
Triples combinations are prohibited from ever changing lanes
Lane change planning is unnecessary regardless of the combination's overall length since a lane change takes the same amount of time no matter how many trailers follow
Lane changes are quicker to complete with more trailers attached

Not quite. The correct answer is highlighted.

Show answer

Correct answer to question 100 (Doubles/Triples): The combination's greater length takes longer to fully clear a lane, and abrupt movements can trigger rearward amplification

Why

A longer combination takes more time and distance to clear a lane, and a rushed or abrupt lane change increases the risk of triggering rearward amplification through the trailers.
