Question 8 of 25
Why does a long truck swing wide when turning left at an intersection?

Show answer
Answer: B. To stop the rear wheels running over the kerb or hitting objects
The rear wheels track inside the front wheels. Going further into the intersection before turning stops them mounting the kerb.
