Driver and Vehicle Standards Agency (DVSA)
Car and Trailer (B+E) test – Show me Tell me Questions You will be asked up to 5 of the following questions. Some will be a 'show' question where you may need to open the bonnet to identify certain parts of the engine bay, or actually demonstrate how you would make a safety check. The other questions will be a 'tell' question whereby you will need to simply describe what you would do. Even though you should have been through these questions with your instructor before you take your test, it is easy to forget, or get your words mixed up when under pressure... Do not worry. If you get a question wrong, you will not directly fail your test. A driver fault (minor) will be marked. The possible questions are listed below. There are some pictures, but your instructors car and trailer may vary from the pictures below.
Q1. Open the bonnet, identify where the brake fluid reservoir is and tell me how you would check that you have a safe level of hydraulic brake fluid.

Q.2 Show me how you would check that the direction indicators are working. A. Applying the indicators or hazard warning switch and checking functioning of all indicators.
Q3 Tell me the main safety factors involved in loading this vehicle.
A. The load should be distributed evenly throughout the trailer. Heavy items should be loaded as low as possible so that they are mainly over the axle(s). Bulkier, lighter items should be distributed to give a suitable ‘nose weight’ at the towing coupling. The nose weight should never exceed the vehicle manufacturer’s specifications.
Q4. Tell me the main safety factors involved in securing a load on this vehicle.
