Junction 17 has B + E Instructors available to train across the UK.
If you want to tow a trailer weighing more than 750 kilograms when the combined weight of the towing vehicle and trailer is more than 3,500 kilograms you will have to pass a further test in category B+E. You will then be able to tow trailers up to 3,500 kilograms. To pull a heavier trailer you must pass a C1E test.
If you got your driving entitlement before 19 January 2013 you will retain it. There are no further changes to rules on towing trailers. Full DVLA Details
