Towing a Caravan: What Do You Need to Know

Towing a Caravan: What Do You Need to Know

Caravan holidays can be so much fun. The open road, the ability to pick any destination, the caravan community. It really is a Great British pastime that has to be tried by all.

But if you're new to the caravan towing lifestyle, then the thought of pulling a 1000kg load down a dual carriageway can be a tad overwhelming.

No doubt you're thinking:

“Can I tow a caravan on my license?", “Where can I learn to tow a caravan?", and “What do you need to tow a caravan?".

To help you tow safely, we've put together this complete guide. Detailing what you need to know about caravan towing, this guide covers a range of caravan towing tips that will have you towing a caravan in no time.

What size caravan can I tow on a car licence?

The rules on what caravan you can tow are quite straightforward. However, there are different rules depending on when you passed your driving test outlined by the government.

If your driving licence was issued on or after 1 January 1997 you can:

  • Tow a trailer that weighs up to 3,500kg MAM

MAM stands for 'maximum authorised mass'. This is the complete weight of the car, trailer (caravan) and the trailer contents combined.

If your driving licence was issued before 1 January 1997 you can:

  • Drive a towing vehicle and trailer combination of up to 8,250kg MAM.

Additional guidance for towing over the age of 70

If you're 70 or older and enjoy towing a caravan or trailer, here's what else you need to know:

Renewing Your Licence:

  • All driving licence entitlements expire at 70. However, category B (standard car licence) automatically renews upon completion of a simple eyesight test.
  • Category B+E (car and trailer), which allows towing heavier trailers, only remains valid if it was obtained before your 70th birthday. If you acquired it later, you'll need to renew it by passing a B+E driving test.

Medical Clearance:

  • While not a legal requirement, The Caravan Club recommends a D4 medical test at age 70 to ensure your fitness for towing. This is especially important if you have any pre-existing medical conditions.
  • You must still pass the standard eyesight test during your licence renewal process.

What can my car tow? (weight)

Making sure you can legally tow your caravan is vital. Failure to correctly match the weight of a car and caravan is an easy way to end up with a large fine, points on your licence or worse... a big crash.

To figure out what your car can tow, you can either use:

  • The VIN plate method
  • A dedicated online calculator

What is the VIN Plate Method?

The maximum towing capacity for each vehicle is set by the vehicle manufacturer. This information can be found on the Vehicle Identification Plate (VIN plate). The VIN plate can usually be found under the bonnet or on a door pillar.

It contains 4 lines of numbers:

  • 1st Line - 2500kg - Gross Vehicle Weight
  • 2nd Line - 4800kg - Gross Train Weight
  • 3rd Line - 1250kg - Maximum front axle load
  • 4th Line - 1300kg - Maximum rear axle load

The maximum towing capacity can be calculated by subtracting the gross vehicle weight from the gross train weight.

If the weight in the 1st and 2nd line are identical or line 2 doesn't contain a value, then your towing capacity is zero kg.

This means that your car manufacturer has concluded that your car is not capable of towing.

What is a Tow Match Calculator?

If you find that method a little complicated, you can use a dedicated caravan tow match calculator provided by a third-party service.

These calculators have a catalogue of VIN plate numbers stored in their memory, and you can easily discover your car's towing capacity in a few clicks.

However, there is a small fee for using these services and there have been reports that they are not always 100% accurate on obscure car models.

What can my car tow? (width and length)

Now you have figured out what your car can tow in weight, it's also important to consider what your car can tow in width and length.

These are the two main rules:

  • The maximum towing width is 2.55 metres
  • The maximum towing length is 7 metres

Unfortunately, there is no third-party service that can give you these figures. You will need to access a vehicle manual and calculate the overall width and length. Alternatively, you can perform a double check using a tape measure.

What is the legality of towing a caravan?

Alongside the obvious licensing and weight rules, you will also find that there are a variety of other laws that you must adhere to when towing a caravan. These include:

  • All towbars must meet type approved EU regulations. All towbars sold by Witter are type approved and are specifically designed for your vehicle
  • Do not exceed the 50mph speed limit on a single carriageway
  • Do not exceed the 60mph speed limit on dual carriageways
  • Never carry passengers in a caravan while driving
  • Your number plate and registration number must be clearly displayed at the rear of your caravan
  • Your rear lights must be working and visible. Double check all your vehicle lights before driving
  • Any caravan over 750kg must have a working brake system
  • You must fit suitable towing extension mirrors, especially if you are towing a large caravan or trailer that is wider than the rear of your car, so you can maintain an adequate view of the road behind you. Failure to do so could lead to 3 points on your licence and a £1,000 fine.


Beware of snaking and pitching! Snaking is when your trailer sways from side to side and pitching is when it moves vertically, pulling on the rear of the car. To avoid snaking and pitching you can:

  • Pack the caravan carefully so that your car and caravan are equally matched
  • Add a caravan stabiliser to your car or use the anti-sway function if you have a newer car to give you more stability on the road

However, if there is a big gust of wind or a lorry goes past, you may not be able to completely prevent swaying. If you do start to sway, take your feet off the pedals and keep steering in a straight line until you regain stability.

How do I load a caravan correctly?

Packing your caravan correctly is the key to towing as safely as possible. Failure to place heavy and light objects in the right area can lead to an unbalanced load and is one of the number one causes of snaking.

Follow these rules:

  • Secure heavy loads low down and over the axles
  • Do not place heavy items at the very front or rear of the caravan
  • Do not drive with full water or waste tanks (the water will move when driving and can cause snaking)

How to tow a caravan safely

So, you've checked your vehicle's towing capacity, selected the right towbar, checked other legalities and hitched your caravan to your vehicle using a caravan mover…now it's time to hit the road.

Here are some practical tips to help you get from A to B and enjoy the journey.

Hitting the road:

  • Drive slow and steady. Allow extra time for braking and accelerating and be prepared to take corners wider than usual.
  • Be aware of your surroundings. Pay attention to other vehicles, cyclists, and pedestrians and give yourself plenty of space.
  • Use your mirrors regularly. Check your mirrors frequently to make sure you're not towing too close to the curb or other vehicles.
  • Take breaks. Stop every few hours to stretch your legs and check on your caravan.


  • Reversing with a caravan can be tricky, so it's best to practise in a safe area before you try it on the road.
  • Get someone to guide you. If you have someone to help you, they can stand outside the caravan and guide you into position.
  • Take it slow and be patient. It takes time and practice to master reversing with a caravan.

And, finally, make sure you plan your route carefully. Choose routes that are suitable for caravans and avoid narrow roads and steep hills so you don't get yourself stuck in a tight spot.

Where can I learn to tow a caravan?

Towing a caravan is not difficult, but it can be quite intimidating. If you are worried about towing, then it's probably best to get at least one lesson.

You can learn the basics of manoeuvring the caravan, mirrors, preparing the caravan and the importance of electronic stabilisers. This will provide you with so much more confidence when jumping in the driving seat.

So, where can you get behind the wheel?

You will also be able to find local caravan driving instructors in your area.

Does towing a caravan affect my insurance?

Your car insurance will cover your car, but it will not cover your caravan. You will need to purchase a separate caravan insurance policy to cover any damage caused to your caravan in the event of an accident.

Please note: It is not a legal requirement to have caravan insurance. Your car insurance will still cover third-party damage to another vehicle.

It is also worth noting that fitting a towbar can also affect how your car insurance premium is calculated. Fitting a towbar is classified as a car modification so it is important that you notify your insurance provider about this change to your vehicle.
