Motorhome Towing Rules in the UK (Complete Guide for 2026)

Towing a car, trailer or small vehicle behind a motorhome is a popular way to make travelling easier once you arrive at your destination. Many motorhome owners choose to tow a small car or trailer so they can explore without moving the motorhome itself.

However, UK motorhome towing laws can be confusing, especially when it comes to driving licences, weight limits and legal requirements.

This guide explains the motorhome towing rules in the UK, what you can legally tow and how to stay safe and compliant.


1. Check Your Driving Licence First

The most important rule when towing with a motorhome is whether your driving licence allows it. Your entitlement depends largely on when you passed your driving test.

If you passed before 1 January 1997

Most drivers who passed before this date can drive vehicle and trailer combinations up to 8,250kg Maximum Authorised Mass (MAM).

This means many motorhome and trailer combinations are allowed without taking an additional test.

If you passed after 1 January 1997

Drivers who passed after this date are typically limited to:

  • Vehicles up to 3,500kg MAM
  • Trailers up to 750kg, or
  • A combined vehicle and trailer weight of 3,500kg without an additional licence category.

Some motorhomes require a C1 licence if they weigh more than 3.5 tonnes.

2. Motorhome Towing Weight Limits

Even if your licence allows you to tow, you must stay within the vehicle manufacturer’s towing limits.

Important weight terms to understand:

Maximum Authorised Mass (MAM)

The maximum legal weight of the vehicle including passengers, fuel, and cargo.

Gross Train Weight (GTW)

The maximum allowed combined weight of the motorhome and trailer.

Towing Capacity

This is set by the vehicle manufacturer and must never be exceeded.

Before towing anything behind your motorhome, check:

  • Motorhome handbook
  • Vehicle weight plate
  • Tow bar rating

3. Speed Limits When Towing in the UK

If you are towing a trailer or vehicle behind your motorhome, reduced speed limits apply.

The legal limits are:

  • 50 mph on single carriageways
  • 60 mph on dual carriageways
  • 60 mph on motorways

You are also not allowed to use the outside lane of a motorway when towing.

These limits apply regardless of whether the motorhome could normally travel faster.


4. Tow Bar Requirements

If your motorhome is fitted with a tow bar, it must meet certain standards.

For vehicles registered after April 2012, the tow bar must be type-approved for that vehicle.

This ensures the tow bar has been tested for:

  • Structural strength
  • Safety compliance
  • Compatibility with the motorhome chassis

Because motorhomes often have water tanks or equipment underneath, professional installation is recommended.


5. Legal Equipment Required When Towing

When towing with a motorhome in the UK, you must have:

Number Plate

The trailer or towed vehicle must display the same number plate as the motorhome.

Lights

The trailer must have working:

  • Brake lights
  • Indicators
  • Tail lights

Towing Mirrors

If the trailer is wider than the motorhome, towing mirrors are legally required so you can see clearly behind you.

Failing to use proper mirrors could result in fines and penalty points.


6. Can You Tow a Car Behind a Motorhome?

Many motorhome owners tow a small car using:

  • A trailer
  • An A-frame
  • A tow dolly

However, UK rules can be complicated.

If you tow a car using an A-frame, the law generally treats the car as a trailer, meaning it must meet the same braking and lighting regulations.

Because of this, many motorhome owners choose to tow a car on a trailer, which is usually the simplest legal option.


7. Safety Tips for Towing With a Motorhome

Following a few safety practices can make towing much easier:

Check nose weight

Too much weight on the tow bar can affect steering and braking.

Load the trailer correctly

Keep heavy items low and balanced to avoid instability.

Practice manoeuvring

Driving with a trailer takes time to get used to, especially when reversing.

Inspect the tow bar regularly

Check for damage, rust, or loose bolts before long trips.


8. Common Motorhome Towing Mistakes

Many drivers accidentally break towing rules without realising it.

Common issues include:

  • Exceeding towing weight limits
  • Not checking licence entitlements
  • Incorrect number plates
  • Not using towing mirrors
  • Overloading the trailer

Avoiding these mistakes will help keep your journey safe and legal.


Final Thoughts

Towing with a motorhome in the UK is completely legal and very common, but it’s important to understand the rules before you start.

Always check:

  • Your driving licence entitlement
  • Your motorhome towing capacity
  • Your vehicle and trailer weights
  • Your legal towing equipment

Following these rules will help ensure your trips are safe, legal, and stress-free.
