Speed limits
UK speed limits by vehicle and road
Summary: The sign on the road is only one part of the answer. Vehicle class, towing, weight and the UK nation can all set a lower maximum.

- Speed limits for carsThe national limit changes with the road, and a lower signed limit always wins.
- Speed limits for vansMost vans use goods vehicle limits, even when a car licence is enough to drive them.
- Speed limits when towingTowing reduces the national limit and changes which motorway lane you may use.
- Speed limits for motorhomesThe important figure is unladen weight, not maximum authorised mass.
- HGV speed limitsThe 7.5 tonne boundary and the nation matter on non motorway roads.
- The 20 mph default in WalesThe 20 mph rule is a default for restricted roads, not a blanket limit across Wales.

How do I read a national speed limit sign?
The sign on the road is only one part of the answer. Vehicle class, towing, weight and the UK nation can all set a lower maximum. GOV.UK speed limits and Highway Code rule 124, checked in 2026, publish the table. The law is the Road Traffic Regulation Act 1984, Schedule 6, as amended, including the Welsh 20 mph restricted-road order. A car on a dual carriageway is 70 mph. A van on the same road is usually 60 mph. A car towing is 60 mph. A heavy goods vehicle in Scotland can be 50 mph.
Use the calculator first. It applies the same rows as the topic pages underneath this hub. A lower posted limit always wins. Rule 125 says the speed limit is the absolute maximum and does not mean it is safe to drive at that speed in all conditions.
How do I check the limit before I drive?
- Choose the vehicle class: car, van, motorhome or goods vehicle.
- Say whether you are towing, and enter the published weights the calculator asks for.
- Choose the nation, because Wales uses 20 mph on restricted roads and Scotland and Northern Ireland drop heavy goods figures.
- Choose the road type: built-up, single, dual or motorway.
- Obey any lower sign, including variable motorway signs, even if the calculator showed a higher national maximum.
A van and a car on the same dual carriageway
Example
A car and a panel van both at 68 mph on an unsigned dual carriageway
- Road
- Unsigned dual carriageway, England
- Car
- Not towing
- Van
- Goods van, not car derived, not towing
- Speed
- 68 mph for both
- The car national dual-carriageway limit is 70 mph, so 68 mph is legal for the car.
- The van national dual-carriageway limit is 60 mph.
- 68 mph is 8 mph over for the van.
- GOV.UK speeding penalties start at £100 and 3 points for the van.
The car is inside the limit. The van is over. The sign is the same. The vehicle class is not.
What is the penalty for exceeding the limit?
GOV.UK says the minimum penalty is a £100 fine and 3 penalty points. A Notice of Intended Prosecution and a section 172 notice should be sent within 14 days of a camera catch, and the section 172 must be returned within 28 days. A court can fine up to £1,000, or £2,500 on a motorway, and can disqualify. New drivers lose the licence at 6 or more points within 2 years of passing. A speed awareness course may be offered. There is no right to one.
What changed in Wales in 2023?
Restricted roads in Wales default to 20 mph from 17 September 2023, under the Restricted Roads (20 mph Speed Limit) (Wales) Order 2022. Those roads are usually built-up streets with street lights no more than 200 yards apart. Repeater 20 mph signs are generally not used where that default applies. A signed 30 mph exception is legal where the highway authority has made a traffic regulation order. Dual carriageways, motorways and other signed limits stay as they are. The Wales 20 mph page is the place for how to ask for a review.
England, Scotland and Northern Ireland still use 30 mph as the usual built-up default, with 20 mph where it is signed or zoned. An English street-light habit in a Welsh town is how a 30 mph cruise becomes a 10 mph excess. The calculator's nation choice switches that built-up default.
Do vans, motorhomes and lorries use the car figures?
Most vans are goods vehicles for speed limits: 50 mph on a single carriageway and 60 mph on a dual carriageway, and 70 mph on a motorway when not towing and not over 7.5 tonnes. A qualifying car derived van, maximum laden weight no greater than 2 tonnes, and a dual purpose vehicle not over 2.04 tonnes unladen, use car limits instead. A motorhome uses 3.05 tonnes unladen as its boundary, which is not the 3.5 tonne MAM figure people remember. Goods vehicles over 7.5 tonnes drop further, and Scotland and Northern Ireland use 40 mph on a single carriageway and 50 mph on a dual carriageway for that heavy class.
Towing one trailer with a car, car derived van or motor caravan is 50 mph on a single carriageway and 60 mph on a dual carriageway or motorway, and the right-hand lane of a three-lane motorway is prohibited. The topic pages under this hub take each class in turn. Use the calculator if you have the weights, then read the page for the class you actually drive.
How do I challenge a speeding notice?
If a camera caught the vehicle, GOV.UK says a Notice of Intended Prosecution and a section 172 notice should arrive within 14 days. You must return the section 172 within 28 days naming the driver. Ignoring it can mean court. You can plead not guilty to a fixed penalty and go to court, where the fine can be higher. This site's speeding pages cover the Sentencing Council bands and the NPCC enforcement table. This hub is the place to check whether the limit you were measured against was the right class.
A van driver who was compared with a 70 mph dual-carriageway car limit, when the van row is 60 mph, still has an excess if they were at 68 mph. The class is the first question. The band is the second. New drivers should treat 3 points as halfway to a revoked licence.
What are the common speed limit mistakes?
Treating a national speed limit sign as 70 mph on a single carriageway. Treating two lanes each way as a dual carriageway when there is no central reservation. Using car limits in a panel van. Using 3.5 tonnes MAM as the motorhome speed test. Towing at 70 mph on a motorway. Using English 30 mph street-light habits in Wales. Assuming a limiter setting such as 56 mph is the legal maximum for a lorry, when the Schedule 6 motorway figure above 7.5 tonnes is 60 mph.
Hire cars, company cars and foreign vehicles on GB roads use the GB table for what they actually are. A hire agreement can set a lower in-contract cap. That is not a different national limit. Confirm the class, the nation and the road type before you copy a habit from the car you drive at weekends.
The topic pages under this hub take each class in turn: cars, vans, towing, motorhomes, heavy goods vehicles, and the Welsh 20 mph default. The calculator at the top of this page is the same table. A lower posted limit always applies. If you have been sent a notice, check the class first, then read the speeding pages for the penalty bands.
Where does the law sit?
Highway Code rule 124 is the table drivers actually read. The Road Traffic Regulation Act 1984, Schedule 6, is the statute behind it, as amended for England and Wales variable limits and for the Welsh 20 mph restricted-road order. GOV.UK speed limits restates the same rows in plainer words. nidirect publishes the Northern Ireland Highway Code text for rules 103 to 158. The calculator on this page does not invent a fifth table. It applies those published rows to the vehicle, nation, road and towing status you enter.
Speeding penalties are a different document. GOV.UK speeding penalties names the £100 and 3 point minimum, the 14 day Notice of Intended Prosecution, the 28 day section 172 reply, the court maxima of £1,000 and £2,500 on a motorway, and the 6 point new-driver revocation. The Sentencing Council guideline and the NPCC enforcement table sit on the speeding pages. Use this hub to find the limit, then those pages to find the band.
Built-up defaults are 30 mph in England, Scotland and Northern Ireland, and 20 mph on restricted roads in Wales. A dual carriageway is defined by a central reservation, not by the number of lanes. A national speed limit sign means the national maximum for that vehicle on that road. The topic pages spell out each exception, including car derived vans, the 3.05 tonne motorhome unladen boundary, and the 7.5 tonne goods-vehicle split.
Common questions
- Does a speed limit sign apply to every vehicle?
- It sets the road limit, but some vehicle classes have a lower national maximum. The lower of the signed road limit and the vehicle limit applies. A van, a car towing a trailer and a heavy goods vehicle can all be below the number on the sign. The calculator on this page picks the national maximum for the class you enter.
- Is the national speed limit always 60 mph?
- No. It depends on road and vehicle type. Cars use 60 mph on a single carriageway and 70 mph on a dual carriageway or motorway, while vans, towing vehicles and heavy goods vehicles can have lower limits. A national speed limit sign means the national maximum for that vehicle on that road, not a single number.
- Does Wales have different speed limits?
- The default on restricted roads in Wales is 20 mph. Signed exceptions exist, and the national limits for unrestricted single carriageways, dual carriageways and motorways still depend on vehicle type. The change took effect on 17 September 2023. Repeater signs are generally not used where the restricted-road default itself applies.
- What is the minimum speeding penalty?
- GOV.UK says the minimum penalty is a £100 fine and 3 penalty points. A court can fine up to £1,000, or £2,500 if you were driving on a motorway, and can disqualify. New drivers lose the licence at 6 points within 2 years of passing the test. A Notice of Intended Prosecution should arrive within 14 days of a camera catch.
- Does a dual carriageway always mean 70 mph?
- No. Seventy mph is the national car limit on a dual carriageway, but a signed lower limit applies, and vans, towing outfits and heavy goods vehicles have lower national maxima. A dual carriageway is defined by a central reservation, not by the number of lanes.
- Do Northern Ireland limits match Great Britain?
- Built-up roads in Northern Ireland use 30 mph unless signs say otherwise, matching England and Scotland rather than Wales. Heavy goods vehicles over 7.5 tonnes use the lower Scottish and NI single and dual figures. nidirect publishes the NI Highway Code table. The calculator on this page includes a Northern Ireland nation choice.
- Can local councils set their own limits?
- Yes. GOV.UK says local councils can set their own speed limits in certain areas, and these must be clearly signed. Variable signs on some motorways and dual carriageways can change the maximum. Until the sign changes, the current signed limit or the national default is the legal limit.
- Does a speed limiter change the legal limit?
- A limiter restricts how fast the vehicle can go. It does not raise or lower the legal maximum. GOV.UK says a limiter must be fitted on vehicles with more than 8 passenger seats and on goods vehicles with a maximum laden weight of more than 3.5 tonnes, and that having a limiter may mean the vehicle cannot reach the speed limit.
