1. The requirement for taking the test does not apply if the Maximum Authorised Mass (or MAM) of the trailer is under 750Kgs. The MAM is the maximum
potential weight of the trailer and it’s contents as shown on the weight plate or manufacturer’s handbook and not the actual weight. Similarly, if you passed
your car test prior to 1st January 1997, you do not need to take the additional test.
For example, most horse trailers have a MAM of between 2 tonne and 2.5 tonne; most caravans are between 1.2 and 1.5 tonne.
2. If the MAM of the trailer is over 750Kgs you need to take the test if the following weight combinations apply:
Either The combined MAM of the car and trailer exceeds 3500kgs (3.5 tonnes)
or The MAM of the trailer is greater than the unladen weight of the towing vehicle.
3. If you passed your car test on or after 1 January 1997 and either of the above weight combinations applies, you will need to take the test. This will give
you B+E entitlement.
4. If the combined MAM is less than 3500Kgs, and the MAM of the trailer is less than the unladen weight of the vehicle, you will not need to take the test.
5. If you passed your car test before 1 January 1997 you will have category B+E entitlement on your license already and will not need to take the test.
