Many people assume that driving a Heavy Goods Vehicle (HGV) always requires a commercial driving licence. While this is generally true, there are certain exceptions where you can legally drive specific heavy vehicles with just a standard car licence.
In this guide, we’ll explain when it’s allowed, the rules you must follow, and the types of vehicles you can drive without an HGV licence.
What Is a Commercial Driving Licence?
A commercial driving licence is required to operate large or heavy vehicles for business purposes. This includes trucks, trailers, and buses used for transporting goods or passengers.
To obtain an HGV licence, drivers must pass multiple tests and meet strict eligibility requirements.

What Is MAM (Maximum Authorised Mass)?
MAM refers to the total weight of the vehicle plus the maximum load it can carry. It plays a crucial role in determining which licence you need.
- 3.5 to 7.5 tonnes → Requires Category C1 licence
- Above 7.5 tonnes → Requires Category C licence
Can You Drive an HGV with a Car Licence?
Yes—but only in specific situations. If you hold a full Category B (car) licence, you may drive certain heavy vehicles without additional HGV training, provided they meet specific conditions.
Exempted Heavy Goods Vehicles
You can drive the following vehicles with a car licence under special exemptions:
- Vehicles powered by wood or coal-burning engines
- Vehicles designed for engineering or construction operations
- Forklift trucks or dumper trucks used for personal purposes
- Agricultural vehicles like combine harvesters (excluding some tractors)
- Off-road haulage tractors (under weight and speed limits)
- Digging machines (only for traveling between work sites)
- Vehicles used for transporting lifeboats and related equipment
- HGVs manufactured before 1 January 1960 (used unladen)
- Articulated vehicles with unladen weight under 3.5 tonnes

- Vehicles used by authorities to clear road obstructions
These exemptions apply only when vehicles are used for specific purposes—not for commercial transport.
