This is because not all vehicles are treated the same on the road, and some may be subject to lower speed limits without the driver realising.
With more Brits opting for road trips and staycations, many drivers are turning to campervans and motorhomes for summer travel.
How your campervan is registered however, could change the speed you are legally allowed to travel at.
7 Common Speed Camera Myths
If a campervan is still classified as a commercial vehicle, it may be subject to lower speed limits than a standard car.
This can catch drivers out, especially as limits vary depending on weight, road type and whether a trailer is attached.
The Highway Code sets out clear rules for different vehicle types and failing to follow them could result in fines or penalty points.
Understanding the difference before setting off could help drivers avoid unexpected penalties and keep journeys on track.
Paul Gorry, from Auto-Trail, explained: “Many drivers assume their campervan follows the same speed limits as a car, but that is not always the case, especially if the vehicle is still registered as a commercial van.
“If a campervan is classed as a light goods vehicle up to 3.5 tonnes, the national speed limit is typically 50mph on single carriageways and 60mph on dual carriageways, which is 10mph lower than a car.
“This difference often comes down to how the vehicle is registered rather than how it is being used, which can lead to confusion for owners who have converted a van into a camper.
“Vehicles still classified as vans must follow lower speed limits on certain roads, particularly single carriageways, which can catch drivers out if they assume they are treated the same as a motorhome.
“This misunderstanding can lead to speeding fines, especially for those new to campervan ownership.”
Speed limits for campervans and motorhomes are largely based on weight, with 3.05 tonnes being a key threshold that determines whether car or van limits apply.
For vehicles under 3.05 tonnes, drivers can follow standard car limits, including 60mph on single carriageways and 70mph on dual carriageways and motorways.
Road signs many drivers don’t know
Once a campervan exceeds that weight, the limits drop to 50mph on single carriageways and 60mph on dual carriageways, even though motorway speeds can remain at 70mph.
Mr Gorry stressed the importance of checking your vehicle classification with the DVLA before setting off on your journey.
He said: “Before heading off on a trip, drivers should check both the weight of their campervan and how it is registered with the DVLA.
“A campervan that looks like a leisure vehicle may still be legally treated as a commercial van, which changes the speed limits that apply.
“Taking a few minutes to confirm this can help drivers avoid fines and keep their journey running smoothly.”
How do speed cameras work?
Speed cameras work using radar or road markings to monitor a vehicle’s speed and capture evidence of any offence.
While older cameras used film, most modern devices are fully digital and can even track your average speed over many miles.
These digital systems record:
- Vehicle speed
- Time and location of the offence
- Vehicle registration
- Road speed limit
In some cases, they even capture a clear image of the driver and passenger.
What Speed Actually Triggers a Camera?
Contrary to common belief, there’s no universal “10% + 2mph” rule baked into law.
Experts from BigWantsYourCar.com explained: “The idea that you’re safe doing 35mph in a 30 zone is one of the biggest myths we hear.
“Technically, you’re liable for a fine the moment you go even 1mph over the limit.”
While the National Police Chiefs’ Council (NPCC) does recommend a “10% plus 2” margin to allow for officer discretion, this is not a legal threshold and can vary depending on the enforcement area or the officer reviewing the case.
RAC advice adds: “The law states that you are liable for a speeding fine as soon as you exceed the limit, so if you’re doing 31mph in a 30 limit or 71mph on a motorway, you’re breaking the law and could receive a fine.
“It is well worth remembering this is totally dependent on the officer who catches the speeder, and it is up to that officer whether to fine the offender or not.
“The best advice is to not speed full stop.”
Common speed camera myths
Here are some other common speed camera myths :
Is it true that speed vans have to be visible at all times?
No. There are no laws about visibility, so nothing is stopping an officer from operating in the dark. But they don’t often choose to do this and maintain that being visible acts as a deterrent in its own right.
Go Safe Casualty Reduction Officer, Gareth Thomas said: “Legally, we don’t have to be visible. I could camouflage myself if I wanted to – but it’s all about being fair, education and preventing an accident. Even if I parked my van and went for a walk somewhere, it would deter people from speeding right away.”
Is it illegal to flash your headlights to alert motorists of a GoSafe speed van?
If drivers choose to flash to warn others about a speed van, they could be in breach of the law. Under section 89 of the Police Act 1997 it is an offence to “wilfully obstruct a constable in the execution of his/her duty”.
However, Gareth says while it is an offence, it is very difficult to prove. He said: “It doesn’t bother me that people flash to warn them of the speed van – I just want to educate people and the van to act as a speed deterrent.”
What happens if I am caught speeding?
It all comes down to the circumstances within which you were caught speeding, and how much you were more than the limit. The minimum penalty for being caught speeding on the UK’s roads is a £100 fine.
But Gareth explained in some circumstances, police can offer the option of attending a speed awareness course – an alternative to a fine and penalty points. Gareth, said: “An accredited course is far more likely to improve driver behaviour and consequently make our roads safer.
“Courses are available to drivers who respond quickly to the ‘notices’ and who were driving at no more than 10 per cent, plus 9 mph above the posted speed limit.”
So for example, anyone travelling over 86mph on a motorway would not be offered the awareness course. Those who don’t have a clean licence at the time of the office, or if you have been on the course in the last three years, it is unlikely you will be offered the awareness course as an option.
