Towing a trailer with a passenger carrying vehicle

On this page reference is made to the maximum authorised mass (MAM) of vehicles and trailers. This should be taken to mean the permissible maximum weight, also known as the gross vehicle weight.

Subcategory D1: passenger carrying vehicles 9-16 passenger seats

Subcategory D1 vehicles may be coupled with a trailer up to 750kgs MAM. There is no upper weight limit for subcategory D1 vehicles. In order to gain the D1 subcategory, B category licence holders have to meet higher medical standards and pass both theory and practical tests for subcategory D1.

Subcategory D1+E: passenger carrying vehicles 9-16 passenger seats with a trailer above 750kgs MAM

Subcategory D1+E allows vehicles to be combined with a trailer over 750kgs MAM. This is provided the combination does not exceed 12 tonnes MAM and the laden weight of the trailer does not exceed the unladen weight of the towing vehicle.

The trailer must not be used for the carriage of passengers. In order to gain this entitlement category B licence holders have to first pass the theory and practical tests for subcategory D1 and then pass a further D1+E practical test. There is no subcategory D1+E theory test.

Category D: passenger carrying vehicle with more than eight seats

Category D vehicles may be combined with a trailer up to 750kgs MAM. There is no upper weight limit for category D vehicles and national limits apply. In order to gain this entitlement category B licence holders have to pass theory and practical tests for category D (it is not necessary to gain subcategory D1 entitlement first).

Category D+E: passenger carrying vehicle with more than eight seats with a trailer over 750kgs MAM

Category D vehicles may be combined with a trailer over 750kgs MAM. In order to gain this entitlement category B licence holders have to first pass the theory and practical tests for category D and then pass a further D+E practical test.
