Show answer

Correct answer to question 52 (Combination Vehicles): Do not operate the trailer until the spring is repaired or replaced

Why

A cracked spring can fail completely under the stress of a loaded trip, which affects both ride control and braking, so it needs to be fixed before the trailer goes back into service.
