A heavy goods vehicle (HGV) is any vehicle weighing over 3.5 tonnes, including cargo, and designed to transport heavy or bulky goods. HGVs are more commonly referred to as trucks or lorries.
It’s important to understand what qualifies as an HGV to comply correctly with licensing, safety and emissions regulations, as well as planning fleet operations effectively. This page defines: what HGVs are, which vehicles fall into this classification, licence categories, relevant UK/EU regulations and how they differ from LCVs/LGVs.
What is an HGV?
HGV stands for heavy goods vehicle. But what makes them so heavy? HGVs are used to transport large loads from one site to another. Their cargo can vary between consumer goods (e.g. clothing), industrial materials (e.g. construction supplies) and bulk commodities (e.g. fuel). These trucks and lorries are vital to the UK transport and logistics sector, moving goods both nationally and internationally.
In the EU, HGVs are officially known as large goods vehicles
(LGVs). However, to avoid confusion with the category acronym for light goods vehicles
(smaller vans under 3.5 tonnes) the UK uses the term HGV.
What is the difference between HGV and LGV?
The difference between an HGV and a light goods vehicle (LGV) — also known as a light commercial vehicle (LCV) — is their weight. HGVs weigh over 3.5 tonnes, while LGVs weigh 3.5 tonnes or less. The UK classifies vehicles by weight to apply different safety standards, licence requirements and tax rules. This means that factors such as driver training, maintenance and road regulations differ between HGVs and LGVs.
Here’s how they are classified.
| Classification | Weight | Typical examples | Licence type |
|---|---|---|---|
| LGV/LCV | Up to 3.5 tonnes | Delivery vans, small trucks | Category B (standard car licence) |
| HGV | Over 3.5 tonnes | Lorries, articulated trucks | Category C1 or C |
The switch from using LGV to HGV to refer to large/heavy vehicles has its roots in old UK tax practices. Before 1992, large goods vehicles were abbreviated as LGVs for tax purposes, but this caused confusion with references to light goods vehicles. To distinguish between them, the term HGV was introduced.
The differences between light goods vehicles (LGVs) and HGVs in terms of fleet management lie in licensing, compliance and cost. Running HGVs is more expensive due to higher insurance and maintenance costs. They require specialist drivers to handle their significant sizes and are subject to stricter safety and emissions standards. LGVs are therefore considered more apt for last-mile delivery and urban logistics.
What is classed as a heavy goods vehicle?
Any commercial vehicle with a gross weight over 3.5 tonnes, including its cargo, falls into the HGV category. There are many types of HGV, each with a specific purpose and design.
Common examples include:
- Box trucks, curtain siders and Lutons — general freight and high-volume deliveries.
- Flatbed, drop-side and tipper trucks — construction work, bulk materials or easy side loading.
- Refrigerated trucks — temperature-controlled goods.
- Tankers — liquids, gases or bulk goods.
- ADR-certified vehicles — hazardous material.
The specific rules for licensing, safety and road use depend on the vehicle’s exact weight and configuration.
Is a 7.5-tonne vehicle an HGV?
Yes. A 7.5-tonne vehicle is an HGV as the weight exceeds 3.5 tonnes.
That said, there are different weight brackets within the HGV category that divide them by licensing and operational rules.
For example, vehicles between 3.5 and 7.5 tonnes fall into a different licence class to those weighing more than 7.5 tonnes. The lighter class of HGVs typically includes medium-sized commercial vans, removal vehicles and those towing a trailer.
HGV categories and licence requirements
All professional HGV drivers must possess a Driver Certificate of Professional Competence (CPC) that is renewed every 5 years, granted that they have continued the necessary training.
In the UK, the weight and configuration of an HGV determines the type of licence required to legally drive it.
- Category C1: vehicles weighing 3.5-7.5 t.
- Category C: vehicles over 7.5 t without a trailer over 750 kg.
- Category C+E: heavy goods vehicles with trailers exceeding 750 kg, such as articulated lorries.
HGV regulations and compliance
The UK and EU have set strict safety regulations for HGVs due to their size and potential impact. These rules are designed to keep all road users out of risk and ensure professional standards in the freight and logistics industry.
Vehicle safety regulations
Before being allowed to operate on public roads, HGVs must meet a select set of safety requirements:
- HGVs must be fitted with speed limiters, anti-lock braking systems (ABS) and electronic stability control (ESC) for improved handling and collision prevention.
- HGVs must be installed with blind-spot reduction measures, such as mirrors, side cameras and underrun protection systems.
- HGVs must undergo MOT tests and routine safety inspections to ensure continued roadworthiness.
HGV driver regulations
Professional HGV drivers must also follow certain regulations for the sake of their safety and wellbeing:
- Use a digital tachograph to comply with EU and UK driving hours rules to prevent fatigue-related accidents.
- Hold a valid Driver CPC and complete regular refresher training.
- Comply with the weekly driving limits and rest periods set by the Working Time Directive.
Environmental and emissions standards
Environmental regulations are in place to limit the pollution caused by HGVs.
- Euro VI called for stricter engine emissions limits and new technology requirements.
- Cities such as London, Birmingham and Bath have mapped out Low Emission Zones (LEZ) and Clean Air Zones (CAZ) to prohibit or charge for access.
Incentives and funding schemes have also been set up to encourage vehicle replacement and vehicle retrofitting to cleaner technology.
