Get your heavy vehicle licence

Heavy vehicles types and licence classes

A heavy vehicle has a gross vehicle mass (GVM) or aggregate trailer mass (ATM) of more than 4.5 tonnes.

There are five different types of heavy vehicle. Each heavy vehicle type requires a specific driver licence.

You must obey any conditions listed on your licence at all times while driving. Read about licence conditions.

If you pass a practical competency assessment for a class HR, HC or MC licence, you will get a condition added to your driver licence. This depends on the transmission type of the vehicle you used in the assessment.
