From single carriageways to city centres, understand UK HGV speed restrictions and how to avoid penalties and enforcement action.
Written by Tristan Bacon — Updated 21 September 2026
When you’re driving a heavy goods vehicle (HGV) in the UK, speed restrictions aren’t just guidelines, they’re legal requirements made to protect everyone on the road.
HGV speed restrictions vary depending on road type, vehicle weight, and sometimes even your load. In this guide, we’ll break down the current rules, cover penalties, and share some best practices to help you stay safe and legal.

UK HGV and LGV speed limits at a glance
Always check for posted signs — local limits, roadworks, and smart motorway gantries override these national figures.
HGVs and LGVs each fall under different speed regulations depending on weight and road type. HGVs are vehicles with a maximum authorised mass (MAM) over 3.5 tonnes, while LGVs are anything at or below that threshold.
If you’re still working out the correct vehicle class for your business, our guide on lorry sizes and UK regulations offers a detailed breakdown of weight categories, axle configurations, and legal definitions.
These LGV and HGV speed restrictions aren’t just random numbers; they’re based on years of data about stopping distances, vehicle stability, and accident risks. The full official speed limit table for all vehicle types is published on GOV.UK.
Heavier vehicles take much longer to slow down and are harder to control at higher speeds. For example, a fully loaded 42-tonne HGV has a total stopping distance of around 36 metres at 30 mph, compared to 23 metres for a car — and the gap widens sharply at motorway speeds.
In England and Wales, the national HGV speed limit for vehicles over 7.5 tonnes on single carriageways is 50 mph.
In Scotland the current limit remains 40 mph, though Transport Scotland is progressing legislation to raise it to 50 mph following a national speed management review.
These changes change were implemented in England and Wales on 6 April 2015 to improve safety and reduce dangerous overtaking on rural roads. Scotland did not adopt the same increase and its limits have remained lower since.
In Northern Ireland, HGVs over 7.5 tonnes are also limited to 40 mph on single carriageways.
Dual carriageways offer two lanes in each direction, making it easier for larger vehicles to maintain steady speeds.
The speed limit for HGVs over 7.5 tonnes on dual carriageway roads is 60 mph in England and Wales.
In Scotland the current limit is 50 mph, with a proposed increase to 60 mph subject to the same pending legislation.
In Northern Ireland, the dual carriageway limit for HGVs over 7.5 tonnes is 50 mph.
Light goods vehicles have slightly more freedom when it comes to dual carriageways.
The speed limit for car-derived vans on dual carriageway routes is typically 70 mph if not towing. However, if towing a trailer, the limit drops to 60 mph to maintain stability and safety.
Motorways are the safest roads for long-distance freight thanks to controlled access and multiple lanes.
The HGV motorway speed limit for vehicles over 7.5 tonnes is 60 mph. This limit balances travel efficiency with the need for longer braking distances and safe manoeuvring.
For many drivers working in a freight exchange network, motorways make up a large part of daily operations. The smoother flow of motorway driving, especially smart motorways and toll roads with less traffic, helps keep schedules on track and cargo moving efficiently across the country.
Whether you’re driving a rigid lorry with a trailer or a full articulated rig, the speed limit remains 60 mph on motorways. Articulated vehicles make up a large portion of UK freight traffic, so these limits apply to many haulage operators.
Drivers must remain aware of their vehicle’s length, especially when overtaking or changing lanes.
LGVs can usually follow the same motorway speed limits as standard passenger vehicles. This means 70 mph is allowed for LGVs not towing trailers.
However, it’s important to note that this 70 mph limit is not universally applicable. It applies only to car-derived vans. Larger vans (up to 3.5 tonnes) that are not car-derived must stick to 60 mph on dual carriageways, even if they’re not towing.
If towing, the limit reduces to 60 mph for all LGVs, keeping in line with stability concerns and legal requirements.
Speed limiters are mandatory on most HGVs to help enforce safe driving speeds. Operators can find approved speed limiter centres on GOV.UK.
For vehicles over 7.5 tonnes, the speed limiter is set at 56 mph — 4 mph below the 60 mph legal limit. This means most HGVs physically cannot reach the legal motorway maximum, and the gap exists to account for real-world variables like gradients, wind resistance, and calibration tolerances. If you’re on a motorway and the vehicle in front of you appears to be travelling faster than you despite an unrestricted legal limit, this is why.
It’s worth knowing that a tampered, faulty, or poorly calibrated limiter can allow a vehicle to exceed both 56 mph and the 60 mph limit. DVSA can issue an immediate prohibition notice at the roadside if a limiter is found to be non-functional, and the operator carries responsibility for keeping the device in working order.
If you operate a large haulage business, maintaining these devices is a legal obligation.
The same applies whether you run a single lorry or manage a small haulage business. Regular maintenance helps avoid penalties and keeps your drivers safe on the road.
Once you enter built-up areas, speed limits tighten considerably. Both HGVs and LGVs must stick to 30 mph in towns and cities in England and Scotland unless otherwise posted.
In Wales, the default speed limit on restricted roads (those with street lighting) is 20 mph, following legislation introduced on 17 September 2023. Operators running routes through Welsh built-up areas must comply with the lower limit unless a sign indicates otherwise.
Many local authorities also apply 20 mph zones near schools, residential areas, and high pedestrian zones for extra safety.
Local councils may introduce temporary restrictions for construction or special events. Always check for signage indicating lower limits or roadworks. Ignoring these temporary limits could result in fines and penalty points.
Even if you’re driving in familiar areas, road layouts and limits can change frequently. Keeping up to date ensures you don’t fall foul of unexpected restrictions.
Staying alert helps protect pedestrians, cyclists, and other vulnerable people using the road.
Roadwork zones are one of the most common places HGV drivers pick up speeding offences.
Temporary limits apply for the full length of any active roadwork zone, and most are enforced by average speed cameras — which calculate your speed across the entire stretch, not just at a single point. There is no exemption for HGVs, and tachograph data provides DVSA with a separate record of speed throughout a journey.
On smart motorways, a displayed number on an overhead gantry sign is the mandatory maximum for all vehicles, including HGVs — it replaces the national motorway limit for as long as it is showing. A blank sign or a national speed limit sign (white circle with a diagonal line) means the normal 60 mph HGV motorway limit applies. A red X on a gantry means the lane is closed; driving in a closed lane carries a £100 fine and 3 penalty points.
Ignoring HGV speed restrictions carries stiff penalties that affect both drivers and operators.
Offenders face fines, penalty points, and possible disqualification depending on the severity of the offence. The minimum fixed penalty is £100 and 3 penalty points. If the matter reaches court, fines are set as a proportion of weekly income — up to a maximum of £1,000, or £2,500 for a motorway offence. Building up 12 or more points within three years results in disqualification.
The GOV.UK speeding penalties page sets out the current fine bands and points thresholds.
If you’re thinking of starting a transport company, understanding these regulations early on is key to staying compliant from day one.
For companies, repeated offences can threaten the Operator’s Licence, potentially shutting down business operations. Even minor infringements add up quickly if not addressed.
For operators, there is a second and often more serious consequence: every speeding Fixed Penalty Notice issued to one of your drivers feeds directly into your DVSA Operator Compliance Risk Score (OCRS). This is the rating DVSA uses to decide how often to pull your vehicles over for roadside inspection. A higher OCRS means more frequent stops, more delays, and — if the score deteriorates far enough — referral to the Traffic Commissioner for a formal public inquiry.
DVSA holds OCRS data on a rolling three-year basis, so a pattern of speeding offences compounds over time rather than clearing quickly. Operators can check and monitor their OCRS on GOV.UK.
Compliance isn’t just about following rules; it protects your business long-term.
Tachograph data provides clear evidence of speed compliance during audits and inspections. Ensuring your fleet operates within legal limits and UK tachograph regulations keeps your records clean.
Prevention is always better than arguing your case in front of a Traffic Commissioner.
It’s not just drivers of HGVs who need to understand the rules. Other road users should give lorries space, especially when overtaking or merging.
If you can’t see the lorry’s mirrors, assume the driver can’t see you either.
Cutting in too sharply after overtaking can create dangerous situations. Large vehicles need extra time and distance to stop safely.
Giving HGVs plenty of space benefits everyone sharing the road.
Remember that even fully loaded lorries still need to navigate tight junctions and roundabouts. Be patient when following or approaching one in built-up areas.
A little extra caution helps everyone get home safely.

The dual carriageway speed limit for HGVs over 7.5 tonnes is 60 mph. This applies whether fully loaded or empty. Always watch for local speed signs that may override national limits.
On UK motorways, the maximum legal speed for HGVs over 7.5 tonnes is 60 mph. For LGVs not towing, the limit rises to 70 mph. Towing reduces LGV limits to 60 mph.
Yes, HGVs can legally travel at 60 mph on dual carriageways and motorways. However, many vehicles are restricted to 56 mph by mandatory speed limiters. This helps improve road safety and fleet fuel efficiency.
For HGVs over 7.5 tonnes, the dual carriageway speed limit is capped at 60 mph. LGVs may drive up to 70 mph unless towing, in which case it’s 60 mph. Always follow posted signs for local variations.
Scotland and Northern Ireland both have lower national limits for HGVs over 7.5 tonnes than England and Wales. In both nations the limits are 40 mph on single carriageways, 50 mph on dual carriageways, and 60 mph on motorways. Scotland is progressing legislation to raise its limits to match England and Wales, but the change is not yet in force.
The minimum fixed penalty for speeding is £100 and 3 penalty points, regardless of vehicle type. If the case goes to court, fines are set as a proportion of weekly income — up to £1,000, or £2,500 for a motorway offence. For operators, there is an additional business risk: Fixed Penalty Notices contribute to the DVSA Operator Compliance Risk Score, which affects how frequently your vehicles are stopped for roadside inspections.
