Before you set off on a trip with a trailer or caravan, make sure you meet the legal requirements for towing. Check your driving licence and your vehicle and be sure you have the right equipment to be safe on the road.
If you passed your driving test after 1 January 2024 and have an ordinary Category B licence, you can drive either of the following:
For anything heavier you need to take a Category B + E driving test.
The rules are different for drivers who passed their test before 1 January 2024 and have not been banned since. You can find full details by following the link below.
Most standard cars have a maximum recommended towing weight. It's usually listed in the handbook or specification sheet. You can also find it on the vehicle identification number (VIN) plate on the car.
The VIN plate is usually under the bonnet or inside the driver's door. It will list a maximum vehicle weight and a maximum train weight. The maximum vehicle weight is what the fully loaded car weighs and the train weight is the maximum weight for the car plus a trailer. If your VIN plate doesn't list a train weight, you should not use your vehicle for towing.
The width limit for any towing vehicle is 2.55 metres. The length limit is 7 metres for a trailer towed by a vehicle weighing up to 3.5 tonnes (3,500 kilograms).
The equipment you use with your trailer or caravan must meet certain safety standards.
If you get a tow bar for your car, make sure it is type-approved. This means it meets EU regulations and is designed for your car. A type-approved tow bar will have a label with an approval number and details of the vehicles for which it is approved.
If your car was registered before 30 July 1998, your tow bar doesn't need to be type-approved.
If your caravan or trailer is wider than the rear of the towing vehicle, you must by law fit suitable towing mirrors. These mirrors are usually 'E-marked' (mirrors with this mark meet EU requirements).
If you're towing blind (without towing mirrors) or using unsuitable mirrors, you can be:
Any trailer weighing over 750 kilograms must have a working brake system. Some smaller trailers also have brakes, although these are optional. Any brakes on a trailer or caravan must be in good working order. If you haven't used the trailer for while, you may need to get the brakes checked and serviced.
If you attach an A-frame to a car in order to tow it with a larger vehicle, the car plus A-frame counts as a trailer.
If you use a dolly to tow a broken-down vehicle, the dolly counts as a trailer.
In both cases the usual safety regulations for trailers apply.
You can use your motorcycle to tow a trailer if the:
When the trailer is loaded it must weigh no more than 150 kilograms or two-thirds of the kerbside weight of the motorcycle - whichever is lighter.
When hitched, the distance between the end of the trailer and the rear axle of the motorcycle must be no more than 2.5 metres.
American trailers and caravans don't always meet European safety regulations. For example, there are often differences in the braking systems and the size of the ball hitch used for coupling.
If you're considering using an American caravan or trailer in Britain or elsewhere in the European Union, you must first check that it is legal. Follow the link below to download the factsheet about using one of these caravans or trailers in Britain.
