Road user charges and heavy vehicle operation
What the exam tests
This domain checks that you understand road user charges (RUC), how the RUC weight is set, and the operating rules that apply to heavy vehicles.
RUC basics
RUC is a distance-based charge. It applies to diesel vehicles and to all heavy vehicles over 3,500 kg, whatever fuel they use. You buy a RUC licence in units, commonly 1,000 km, and display the label. The price depends on the vehicle type, axle configuration and the RUC weight you choose.
RUC weight
The RUC weight is the maximum weight you declare for the vehicle. It must be at least the heaviest weight the vehicle will operate at, and it must not exceed the legal gross vehicle mass. If you run heavier than your licence, you are under-licensed and commit an offence.
Operating rules
- Keep the RUC label displayed and carry records.
- Overloading, exceeding axle limits and missing RUC can attract infringement fees and penalties.
- Overweight or overdimension loads may need permits and pilot vehicles.
- Heavy vehicles must use weighbridges when directed.
Worked example
A truck has a legal gross vehicle mass of 25,000 kg but is licensed for 20,000 kg RUC. It is loaded to 22,000 kg. The load is under the legal GVM, but the RUC licence is exceeded. The operator must upgrade the RUC weight to at least 22,000 kg before the trip. The exam often separates legal GVM from RUC weight.
Traps
- Thinking RUC applies only to diesel vehicles.
- Confusing RUC weight with the legal GVM.
- Forgetting that a trailer may need its own RUC licence.
- Not displaying the RUC label.
