caravan towing

Are you planning a UK seaside trip or a short city break? If you’re taking a caravan in tow, preparation could be critical. Towing a caravan requires more thought than just driving a car. There are different rules for speeds, lane access, safety checks, and even restrictions on the weight and width. Plus, you might want to consider caravan insurance to cover you during the drive and your holiday.

To ensure your trip runs smoothly, we’ll take you through the need-to-know information for towing caravans – from pre-trip checks to insurance policies.

What can you tow?

Towing a caravan requires a full driving licence (category B)[1], which you receive after passing your driving test. However, there are restrictions on the weight of the caravan you can tow. It all depends on when you received your driving licence2.

Weight guidelines are provided as maximised authorised mass (MAM) measurements, considering the combined weight of a vehicle and a caravan. So, you’ll need to ensure the total MAM of your car and caravan doesn’t exceed the limits when loaded, rather than just the caravan’s weight2.

Driving licences issued before 1 January 1997

If you received your licence before January 1997, the combined MAM weight allowance is up to 8,250kg[2].

Driving licences issued after 1 January 1997

The government introduced changes in Autumn 2021 that removed the need for additional tests to tow trailers up to 3,500kg2. Now, all new licences contain a BE code, so you’re automatically entitled to drive a caravan or trailer with a MAM of up to 3,500kg2.

For anything heavier, you’ll need to take a new test to get a category C1 licence. This will allow you to drive caravans with a total MAM of up to 7,500kg3.

Understanding UK towing and trailer regulations

The government has specific requirements for towing a caravan. Alongside the MAM, you’ll need to comply with width, length, towing bars, and lighting regulations. Here’s what you need to know.

Caravan width

The maximum width for all towed caravans is 2.55 metres4.

Caravan length

The maximum length for all towed caravans is 7 metres, excluding the A-frame (the triangular section where the hitch is attached)4.

Towing bars

Any tow bars used must be EU-approved or ‘type approved’. So, they should have a label including an approval number and the vehicle types it’s approved for5.

Towing mirrors

Towing mirrors give you sufficient rear view while driving. Failure to use these may result in a fine of up to £1,000, plus three points on your licence 5.

A quick visual check might be enough to determine whether you need towing mirrors. But if you’re unsure, check whether the caravan is wider than the width of your car. If it is, use towing mirrors.

Number plates

You should fit your caravan with a licence plate on the rear that matches your vehicle’s licence plate5.

Caravan lights

Your caravan must have lights in 6:

  • Two rear red sidelights
  • Two red stop lights
  • Two amber indicator lights
  • Two triangular red reflector lights
  • An illuminated number plate

Caravans over 1.3 meters wide must also have at least one red fog light. In addition, you must fit caravans or trailers built after 30 September 1990 with front reflector lights and front position lights if wider than 1.6 meters6.

Speed limits

You must stick to the following speed limits when towing a caravan 7:

  • 30 mph (48 km/h) in built-up areas
  • 50 mph (80 km/h) on a single carriageway
  • 60 mph (96 km/h) on a dual carriageway
  • 60 mph (99 km/h) on a motorway (three or four lanes)

Lane access

It’s illegal to use the right-hand lane on a motorway when towing a caravan, including three and four-lane motorways 8.

Preparing your car to tow a caravan

Getting ready for your trip means more than packing a suitcase. The government recommends running some checks to ensure your vehicle and caravan are safe and legal 8.

First, check the maximum weight your car can safely tow and calculate the MAM. Check the vehicle’s handbook or manufacturer’s plate to find this information. It is also recommended that you:

  • Weigh your caravan to ensure it’s within limits — you could take it to a weigh bridge.
  • Check your tyres are correctly inflated and have at least 1.6mm of tread6.
  • Ensure you have the right towing equipment and that it’s fastened correctly, especially the breakaway cable.
  • Ensure all lights and indicators work correctly.
  • Check your brakes are working correctly.

If needed, you can arrange for a free safety check for any caravan up to 3,500kg from the National Trailer and Towing Association (NTTA) 6.

Safety tips for towing a caravan

You should always take extra caution while towing a caravan on the road. In particular, you should consider the following:

  • Make sure all heavy items are loaded on the axle.
  • Ensure all loads are fastened down securely.
  • Make certain all doors, latches, and cables are secure.
  • Never allow passengers in the caravan while you’re towing it.
  • Drive with extra caution, adhering to speed and lane access requirements.

Do you need insurance to tow a caravan?

Insurance is needed to drive on the road with or without a caravan. Some car insurance policies cover towing a caravan, but it’s always worth checking with your provider. However, even if you’re covered, it might only protect against third-party damage, potentially leaving you liable if something goes wrong. That’s why it’s a good idea to consider purchasing Touring caravan insurance to help protect against extra risks.
