When did you pass your car test mark??....if it was prior to jan 1997 you can tow trailers.....if it was after, you havnt got entitlement to tow until you take a trailer test....
Car licences held before 1 January 1997
All drivers who passed a car test before 1 January 1997 retain their existing entitlement to tow trailers until their licence expires. This means they are generally entitled to drive a vehicle and trailer combination up to 8.25 tonnes MAM. They also have entitlement to drive a minibus with a trailer over 750kgs MAM.
Car driving licence first obtained since 1 January 1997
Drivers who passed a car test on or after 1 January 1997 are required to pass an additional driving test in order to gain entitlement to category B+E and all larger vehicles.
Category B+E: Vehicles up to 3.5 tonnes MAM towing trailers over 750kgs MAM
Category B+E allows vehicles up to 3.5 tonnes MAM to be combined with trailers in excess of 750kgs MAM. In order to gain this entitlement new category B licence holders have to pass a further practical test for category B+E. There is no category B+E theory test. For driver licensing purposes there are no vehicle/trailer weight ratio limits for category B+E.
