Incorrect!

When should an endurance brake (retarder) be used?

On motorways only

When braking quickly

You selected this answer

When you stop or park

On long downhill slopes

Correct answer

DVSA theory test explanation

An endurance brake can help to control your speed on long downhill slopes without using the service brake. Reducing the use of the service brake helps to prevent the brakes from overheating and reduces the risk of brake fade.
