Motorhomes can have different speed limits from cars in the UK, depending on their maximum unladen weight and whether they are towing a trailer. Some motorhomes follow the same national speed limits as cars, while heavier models are restricted to lower speeds on single and dual carriageways.
This is particularly important for anyone hiring a motorhome for the first time. A vehicle may look similar in size to another model but fall into a different speed limit category. Before setting off, you need to know which rules apply to the motorhome you are driving.
UK Motorhome Speed Limits at a Glance
The national speed limits for motorhomes are determined by the type of road and the vehicle’s maximum unladen weight.
| Motorhome type | Single carriageway | Dual carriageway | Motorway |
|---|---|---|---|
| Maximum unladen weight of 3.05 tonnes or less | 60 mph | 70 mph | 70 mph |
| Maximum unladen weight over 3.05 tonnes | 50 mph | 60 mph | 70 mph |
| Motorhome towing a trailer | 50 mph | 60 mph | 60 mph |
These limits apply where no lower speed limit is displayed. Signed restrictions, including temporary limits and variable motorway speed limits, take priority.
In built-up areas, the usual limit on restricted roads is 30 mph in England and Scotland and 20 mph in Wales, unless signs indicate otherwise.
The important distinction is that not every motorhome is automatically restricted to 50 mph on single carriageways. Its maximum unladen weight determines which national limits apply.
Does Motorhome Weight Affect the Speed Limit?
Yes. UK motorhome speed limits use a threshold of 3.05 tonnes maximum unladen weight.
A motorhome at or below this threshold can generally travel at the same national maximum speeds as a car. Once its maximum unladen weight exceeds 3.05 tonnes, the limits fall to 50 mph on single carriageways and 60 mph on dual carriageways. The motorway limit remains 70 mph.
Maximum unladen weight versus maximum authorised mass
These two measurements are often confused, but they serve different purposes.
Maximum unladen weight is the figure used to determine which national motorhome speed limits apply.
Maximum authorised mass (MAM) is the maximum permitted weight of the vehicle when loaded. It includes the vehicle, passengers, luggage, equipment and other carried items.
Many motorhomes have a MAM of 3,500 kg, but that does not automatically place them in the heavier speed limit category.
MAM is particularly relevant when considering which vehicles your driving licence permits you to use.
If you are hiring, ask the motorhome provider to confirm the applicable speed limits before collection. Avoid relying on the vehicle’s appearance or its advertised maximum weight.
Speed Limits on Single Carriageways
Single carriageways are where motorhome drivers are most likely to encounter different national limits.
A motorhome with a maximum unladen weight of 3.05 tonnes or less can travel at up to 60 mph where the national speed limit applies. A heavier motorhome is limited to 50 mph.
This distinction matters when travelling through rural areas such as North Yorkshire, the Lake District and Scotland, where many popular touring routes use single carriageway roads.
Even where 60 mph is permitted, the road may not be suitable for travelling at that speed. Sharp bends, narrow lanes, cyclists, agricultural vehicles and poor visibility can require a much slower approach.
When enjoying scenic drives in North Yorkshire, travelling at a comfortable speed is often more appropriate than trying to maintain the maximum permitted limit.
Are Motorhomes Limited to 60 mph on Dual Carriageways?
Not always.
Motorhomes with a maximum unladen weight of 3.05 tonnes or less can travel at up to 70 mph on dual carriageways where the national speed limit applies.
Heavier motorhomes are restricted to 60 mph.
Drivers should also be aware that a dual carriageway is defined by a central reservation separating opposing traffic, not simply by the number of lanes. A road with one lane in each direction can still be a dual carriageway if the carriageways are physically separated.
The national speed limit sign therefore needs to be interpreted alongside the road type and the motorhome’s weight category.
Motorhome Speed Limits on Motorways
The national motorway speed limit is 70 mph for motorhomes in both weight categories, provided no lower restriction applies.
However, 70 mph is a maximum rather than a recommended cruising speed.
Motorhomes are generally taller and heavier than passenger cars, which can affect their handling in strong crosswinds and when passing larger vehicles.
Fuel consumption can also increase noticeably at higher speeds. Travelling at a steady, comfortable speed may be more economical and less tiring, particularly over longer distances.
Motorway drivers must also follow variable speed limits displayed on overhead gantries. These restrictions apply to motorhomes just as they do to cars.
Do Motorhome Speed Limits Change When Towing?
Yes. A motorhome towing a trailer is subject to lower national speed limits.
The maximum permitted speeds are:
- 50 mph on single carriageways.
- 60 mph on dual carriageways.
- 60 mph on motorways.
This applies when towing a trailer carrying luggage, equipment or another vehicle.
There are also additional motorway restrictions. Vehicles towing trailers must not normally use the right-hand lane of a motorway with three or more lanes.
Before towing, check that the motorhome is approved for the trailer’s weight and that the driver has the appropriate licence entitlement. If you are hiring, you must also confirm whether the hire agreement permits towing.
Speed Limits in Towns, Villages and Residential Areas
The national speed limits for open roads do not override restrictions in built-up areas.
In England and Scotland, restricted roads with street lighting generally have a 30 mph limit unless signs indicate otherwise.
In Wales, the default limit on restricted roads is generally 20 mph, although some roads have different signed limits.
Local authorities can also introduce lower limits in particular areas, including near schools, residential streets and roads with known hazards.
Motorhome drivers travelling across different parts of the UK should pay particular attention to changes in speed limits when entering towns and villages.
Do not rely entirely on your sat-nav, as speed limit information may be outdated. Road signs and applicable legal restrictions determine the limit.
Can Motorhomes Have Speed Limiters?
Some larger motorhomes may be fitted with speed limiters, depending on the vehicle and its classification.
A speed limiter restricts the vehicle’s maximum speed, but it does not automatically adjust to changing road limits.
For example, a motorhome with a limiter set at 60 mph could still exceed a signed 50 mph restriction.
Cruise control should be treated similarly. It can help maintain a consistent speed on suitable roads, but the driver remains responsible for adjusting to traffic, weather, gradients and changing restrictions.
How Speed Limits Affect Motorhome Journey Planning
Speed limits are worth considering when planning a motorhome holiday, particularly if your route includes long stretches of single carriageway.
A journey that looks straightforward in a car may take longer in a larger motorhome. Lower speed limits, narrow access roads and the need for more careful manoeuvring can all affect arrival times.
This is particularly relevant when planning campsite arrivals or travelling between several destinations in one day.
Before setting off, check:
- Vehicle category: Confirm the motorhome’s maximum unladen weight and relevant speed limits.
- Route suitability: Check for narrow roads, low bridges and restrictions affecting larger vehicles.
- Journey duration: Allow enough time for slower roads, breaks and unexpected delays.
- Weather conditions: Reduce speed where wind, rain or poor visibility affects vehicle handling.
- Campsite arrival times: Check the latest permitted arrival time before planning your route.
Knowing the correct speed limits before collecting a motorhome removes one of the uncertainties of driving an unfamiliar vehicle.
For anyone hiring a motorhome, it is worth confirming the vehicle’s weight category during the booking or handover process. That way, you can travel knowing which limits apply rather than making assumptions based on the type or size of motorhome.
FAQs About UK Motorhome Speed Limits
What happens if you receive a speeding ticket in a hired motorhome?
The speeding notice may initially be sent to the hire company as the vehicle’s registered keeper. The company can then identify the person responsible for the hire so the relevant authorities can contact the driver. Some hire agreements also include an administration charge for processing traffic offences, so check the rental terms.
Do campsites have their own speed limits for motorhomes?
Yes. Campsites often set low speed limits on their internal roads to protect pedestrians, children and other guests. These may be considerably lower than public road limits. Follow the speed restrictions displayed at the campsite entrance and throughout the site, particularly around pitches, play areas and shared spaces.
Do campervans follow the same speed limits as motorhomes?
Not necessarily. A campervan’s applicable speed limits depend on its vehicle classification and weight, not simply whether it has a bed or cooking facilities. Some converted vans may remain classified as goods vehicles and have different limits. Check the vehicle’s registration details and classification rather than assuming all campervans follow car speed limits.
Do UK motorhome speed limits apply when driving abroad?
No. Each country has its own speed limits and vehicle classification rules. Some European countries apply different motorway limits to motorhomes above 3.5 tonnes, for example. Before taking a hired motorhome overseas, confirm that international travel is permitted and check the rules for every country on your route.
Where can you find a motorhome’s unladen weight if it is not shown on the paperwork?
The V5C registration certificate may not provide the exact figure needed to establish the applicable speed limit. The vehicle manufacturer or converter may be able to confirm it using the model specifications and vehicle identification number. For a hired motorhome, ask the hire company to establish the correct classification rather than relying on an estimate.
Are motorhomes over 3.05 tonnes limited to lower speeds?
Motorhomes with an unladen weight over 3.05 tonnes have lower speed limits on single and dual carriageways than lighter motorhomes, so check the weight in the handbook.
