For most people, their first full licence is a C Class licence.
If you have a C Class licence, you can drive any vehicle with a gross vehicle mass (GVM) not greater than 4.5 tonnes. This includes most cars, station wagons and minivans.
You can't drive a bus, a truck, a motorcycle or a motor trike. To drive these, you need to qualify for a different class of licence.
