The rules for car drivers who wish to tow a trailer, caravan or horsebox are different depending on when they passed their test.
Drivers who passed their car test before 1 January 1997 can tow a car and trailer combination up to 8,250kg maximum authorised mass (MAM).
Drivers who passed their car test on or after 1 January 1997 can:
· drive a car or van up to 3,500kg MAM towing a trailer of up to 750kg MAM
· tow a trailer over 750kg MAM as long as the combined MAM of the trailer and towing vehicle is no more than 3,500kg MAM
If they want to tow anything heavier, they must pass a car and trailer test (B+E).
