"You MUST NOT tow more than your licence permits, if you passed your car test after 1st January 1997you are restricted on the weight of trailer you can tow"
I don't know what the weight is though.
Also the trailer must not exceed the weight your car is allowed to tow, you should find that in your car handbook.
750kg is it not? when i went for a job with the AA had to sit a test to be able to tow a trailer as i didnt pass my test until after 97. hopefully somone can confirm for definat ethough
If he has had his licence from the age of 18 and is now 27, he can't have passed in July 2008! However, the relevant letters on the licence are BE (or B+E). B means he can drive a car and E means he can put a trailer on it, so the second link in my previous answer is the one that applies.
