Towing trailers with medium-sized vehicles between 3.5 and 7.5 tonnes
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 C1: medium-sized goods vehicles 3.5 to 7.5 tonnes MAM
Subcategory C1 vehicles may be coupled with a trailer up to 750kgs MAM allowing a combination of up to 8.25 tonnes MAM. But unlike category B, the 750kgs MAM trailer weight limit is an absolute limit. In order to gain the C1 subcategory, B category licence holders have to meet higher medical standards and pass both theory and practical tests for subcategory C1.
Subcategory C1+E: medium-sized goods vehicles 3.5 to 7.5 tonnes MAM plus trailer over 750kgs MAM
Subcategory C1+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. In order to gain this entitlement category B licence holders have to first pass the theory and practical tests for subcategory C1 and then pass a further C1+E practical test. There is no subcategory C1+E theory test.
Although 18-year-old drivers are allowed to take a test for subcategory C1+E which will allow trailers in excess of 750kgs MAM to be towed, entitlement is limited to a combination weight of 7.5 tonnes MAM until the driver reaches 21 years. At this time the balance of 12 tonnes MAM entitlement automatically becomes effective.
