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.
If you want to get your heavy vehicle licence you must follow these steps:
Step 1. Learn to drive that type of heavy vehicle.
Step 2. In some cases, pass a heavy vehicle theory test.
Step 3. Pass a driving assessment.
Find out what type of heavy licence you want to get, and then apply for that licence.
All drivers of vehicles with a GVM greater than 15 tonnes must have a zero blood alcohol concentration.
Theory and practical test results remain valid for 12 months from the date of assessment.
If you do not upgrade your licence within this period you will need to sit your test again.
