Speed limits for vehicles

Some drivers must obey speed limits for their vehicles as well as speed limits for the roads on which they are travelling.

The table below outlines the speed limits that apply to different vehicles.

Vehicle speed limit
Type of vehicle to which it applies
65 kilometres an hour (65km/h) On all roads
A single or double deck bus or coach designed for carrying standing passengers
City single bus
80 kilometres an hour (80km/h) On all roads except motorways
A goods vehicle with a maximum authorised mass (MAM) of more than 3,500 kilograms
Truck
90 kilometres an hour (90km/h) On motorways
A goods vehicle with a maximum authorised mass (MAM) of more than 3,500 kilograms
Truck
80 kilometres an hour (80km/h) On all roads
Any vehicle towing a trailer, caravan, horsebox or other attachment
Jeep
80 kilometres an hour (80km/h) On all roads except motorways or dual carrigeways
A single or double deck bus or coach that is not designed for carrying standing passengers
Coach facing left
100 kilometres an hour (100km/h) On motorways or dual carriageways where no lower speed limit is in place
A single or double deck bus or coach that is not designed for carrying standing passengers.
Coach facing right

If the vehicle and road speeds are different, the driver must obey the lower of the two. For example, if a bus designed to carry standing passengers is travelling on a road with a speed limit of 80 km/h, it cannot travel faster than its vehicle speed limit of 65 km/h. But if it is travelling on a road with a speed limit of 50 km/h, it must obey this limit regardless of the maximum speed at which it might otherwise be allowed to travel.
