You are driving a heavy goods vehicle going down a steep and long descent. When must you engage a suitable low gear?
Pick an answer to test yourself
The correct answer: A low gear should be engaged at the start of the descent.
In a heavy goods vehicle on a steep and long descent, engage a suitable low gear at the start of the descent. Waiting until the end is too late, and relying on a high gear and a speed retarder alone is not the correct way to keep control.
