Can I Drive This Motorhome on My Licence?

The driving licence category you need depends mainly on your motorhome's maximum authorised mass (MAM). This checker gives general guidance for drivers in Great Britain based on the vehicle's MAM, power type and the licence entitlement you tell us you currently hold.

Important: This checker is guidance only. It cannot see your DVLA driving record, restriction codes or individual circumstances. Always check the categories shown on your current driving licence before driving.

What Does MAM Mean?

Maximum authorised mass (MAM) is the maximum permitted total weight of the motorhome when fully loaded. It includes the weight of the vehicle itself, plus occupants, fuel, water, luggage, accessories and everything else being carried.

Driving licence categories use the vehicle's plated MAM rather than simply what it happens to weigh on a particular day.

Where do I find it? Your motorhome's MAM may also be described as its MTPLM (Maximum Technically Permissible Laden Mass). You can normally find this maximum weight on the manufacturer's or chassis weight plate (often called the VIN plate), and it may also be listed in the motorhome's technical specifications.

Motorhome Licence Weight Limits

Up to 3,500kg

The normal Category B limit for petrol, diesel and hybrid motorhomes in Great Britain.

Up to 4,250kg

Category B can cover a qualifying zero-emission electric or hydrogen vehicle up to 4,250kg MAM.

3,500–7,500kg

Category C1 covers medium-sized vehicles in this range, subject to the separate zero-emission Category B allowance.

Over 7,500kg

A motorhome above 7,500kg MAM falls outside Category C1 and normally requires Category C.

Passed Your Car Test Before 1 January 1997?

Drivers who passed a Category B car test before 1 January 1997 normally received additional entitlement including Category C1. This is why many long-standing motorhome owners can drive vehicles above 3,500kg without having taken a separate C1 test.

You should still check your current driving record rather than rely on the test date alone.

What Happens to C1 When You Reach 70?

In Great Britain, your driving licence must be renewed when you reach 70 and then every three years. Category C1 cannot be renewed through the standard online over-70 service and must be dealt with separately.

If you rely on C1 to drive a motorhome above the Category B weight limit, check that C1 is still shown after renewal.

Do I Need C1 for a 3,850kg Motorhome?

For a conventional petrol, diesel or hybrid motorhome, 3,850kg is above the normal 3,500kg Category B limit, so Category C1 is normally required.

A qualifying zero-emission electric or hydrogen vehicle is different because current Great Britain Category B rules allow up to 4,250kg MAM.

How Do I Get Category C1?

If C1 is not already on your licence and you need it, GOV.UK explains the process for adding higher vehicle categories. This can include obtaining provisional entitlement, meeting medical requirements and passing the relevant tests.

GOV.UK — adding higher categories

Does Towing Change the Licence You Need?

It can. Category C1 permits a C1 vehicle with a trailer up to 750kg MAM. A trailer over 750kg behind a C1 vehicle can require C1E. Category C similarly allows a trailer up to 750kg; a heavier trailer can require CE.

Downplating or Uprating a Motorhome

Some motorhomes can be professionally downplated or uprated. Downplating can reduce usable payload, while uprating may move the motorhome into a higher driving licence category.

Before changing a plated weight, check the vehicle's technical suitability, axle limits, documentation, remaining payload and your driving entitlement.

Motorhome C1 Licence FAQs

Can I drive a 3,500kg motorhome on a normal car licence?

In Great Britain, a conventional petrol, diesel or hybrid motorhome with a MAM no greater than 3,500kg normally falls within Category B.

Is 3,500kg based on the motorhome's actual weight?

No. Driving licence categories use maximum authorised mass (MAM), which is the vehicle's maximum permitted laden weight.

Can Category B cover a 4,250kg motorhome?

Category B can cover a qualifying zero-emission electric or hydrogen vehicle up to 4,250kg MAM in Great Britain.

Does passing before 1997 mean I have C1?

Drivers who passed Category B before 1 January 1997 normally received C1 entitlement, but you should confirm that C1 is still recorded on your current licence.

Can I drive a motorhome over 7,500kg with C1?

No. Category C1 covers vehicles up to 7,500kg MAM. A motorhome above that limit normally requires Category C.
