HGV Speed Limits by Road Type in the UK: Complete 2026 Guide

HGV speed limits in the UK vary by vehicle weight, vehicle type, and road classification. Goods vehicles over 7.5 tonnes are limited to 60mph on motorways, 50mph on dual carriageways, 40mph on single carriageways, and 30mph in built-up areas. Lighter goods vehicles between 3.5 and 7.5 tonnes follow a different set of limits. The full breakdown by road type and weight category is set out in the table below.

UK Speed Limits for Goods Vehicles: Complete Table

Understanding these limits is essential for every fleet operator, transport manager, and professional driver. The penalties for exceeding them include fines, penalty points, and — for persistent offenders — referral to the Traffic Commissioner.

Road Type	Cars & Vans up to 3.5t	Goods Vehicles 3.5t-7.5t	Goods Vehicles over 7.5t
Built-up areas	30mph	30mph	30mph
Single carriageway	60mph	50mph	40mph
Dual carriageway	70mph	60mph	50mph
Motorway	70mph	70mph*	60mph

*Goods vehicles between 3.5t and 7.5t that are not articulated follow the 70mph motorway limit. Articulated vehicles or those towing a trailer are limited to 60mph.

Important Notes on the Table

Articulated vehicles: Any articulated goods vehicle, regardless of weight, follows the lower speed limits that apply to the over-7.5t category on single carriageways and dual carriageways.

Trailers: A goods vehicle of any weight towing a trailer is subject to reduced limits: 60mph on motorways, 50mph on dual carriageways, and 40mph on single carriageways.

Local restrictions: Many roads carry lower limits than the national defaults. These take precedence. Speed limit signs always override the national speed limit for that road type.

How Speed Limiters Interact with These Limits

Here is where things get interesting for fleet operators. All goods vehicles over 3.5 tonnes must be fitted with a speed limiter under UK law. For HGVs, that limiter is set to 56mph (90 km/h). For more detail on the legal requirements, see our guide on HGV speed limiter law.

This creates a practical situation that every HGV driver and fleet manager needs to understand.

The Motorway Paradox

The national speed limit for HGVs over 7.5 tonnes on motorways is 60mph. However, the mandatory speed limiter is set to 56mph. This means that while the law permits 60mph, the vehicle physically cannot exceed 56mph.

In practice, a speed-limited HGV on a motorway typically cruises at 52-55mph, accounting for slight variations in speedometer accuracy and limiter calibration tolerance. The 60mph limit is effectively a ceiling that the vehicle can never reach.

This is not a conflict in the law. The speed limiter requirement (Construction and Use Regulations, Regulation 36A) operates independently of the road speed limit. The vehicle must comply with both: the road speed limit sets the maximum legal speed, and the speed limiter sets the maximum physical speed. Whichever is lower applies.

On Other Road Types

On single carriageways (40mph limit for heavy HGVs), the speed limiter provides an additional safety margin. The driver must still observe the 40mph limit — the 56mph limiter setting does not grant permission to travel at 56mph on a 40mph road. It simply means that even in the worst case, the vehicle cannot exceed 56mph.

On dual carriageways (50mph limit for heavy HGVs), the same principle applies. The driver is responsible for observing 50mph, with the limiter providing a hard stop at 56mph.

Speed Limits for Buses and Coaches

Fleet operators running passenger service vehicles should note different limits apply.

Road Type	Buses & Coaches (over 12m or over 3.05t unladen)	Smaller Buses & Coaches
Built-up areas	30mph	30mph
Single carriageway	50mph	50mph
Dual carriageway	60mph	60mph
Motorway	60mph	70mph

Coaches and buses must be fitted with speed limiters set to 62mph (100 km/h), which aligns more closely with their 60mph motorway and dual carriageway limits.

Penalties for Exceeding HGV Speed Limits

The penalties for a goods vehicle driver exceeding the speed limit depend on the severity of the offence.

Fixed penalty notice: For minor exceedances, the standard penalty is GBP 100 and 3 penalty points on the driver’s licence.

Graduated penalties: Higher fines and more points apply for greater exceedances. In the most serious cases, a court summons can result in fines of up to GBP 2,500 for motorway offences or GBP 1,000 for other roads.

Driver CPC and operator implications: Repeated speeding offences by drivers within a fleet can trigger a DVSA investigation and referral to the Traffic Commissioner. This can result in conditions being placed on your operator’s licence, or in extreme cases, revocation.

Speed limiter offences: Operating a goods vehicle without a functioning, correctly calibrated speed limiter is a separate offence. A DVSA roadside check finding a non-compliant speed limiter can result in an immediate prohibition notice, preventing the vehicle from continuing its journey. Fines of up to GBP 1,000 apply. Full details are covered in our speed limiter regulations UK guide.

Practical Compliance for Fleet Operators

Managing speed limit compliance across a mixed fleet requires a systematic approach.

Vehicle categorisation: Ensure every vehicle in your fleet is correctly categorised by weight and type, and that drivers know which speed limits apply to the vehicle they are operating on any given day.

Speed limiter calibration: All vehicles over 3.5 tonnes should have their speed limiters calibrated by an approved installer, with records maintained and available for inspection. The speed limiter plate in each cab should be current and legible.

Telematics and monitoring: Modern fleet management systems can alert you when a vehicle exceeds the speed limit for its category on any given road. This provides an evidence trail for compliance and identifies drivers who need additional support.

Driver training: Speed limit awareness should be a core element of driver induction and ongoing training, particularly for drivers who switch between vehicle categories.
