Rules for test vehicles
All test vehicles have to meet certain rules, depending on their category.
Category B1 - quadricycles and light 4-wheeled vehicles
You can only take a test on a category B1 vehicle if you’re registered as disabled.
The vehicle must:
- weigh no more than 550kg unladen
- be able to drive at 37mph
Category F - tractors
Category F includes tractors with 2 or more axles, built for off-road agriculture or forestry work.
Category G - road rollers
If you’re between 17 and 20, these must be small road rollers with metal or hard rollers. They can’t:
- be steam powered
- weigh more than 11,690kg
- be made for carrying loads
Category H - tracked vehicles
Category H vehicles must have adequate all-round visibility to let the driver carry out manoeuvres and deal with junctions safely.
Any vehicle needing a second person to help with observation, such as a military vehicle, can’t be used for a category H test.
Category K - mowing machines or pedestrian-controlled vehicles
A mowing machine is a specialist ride-on grass-cutting vehicle with permanent cutting equipment. You must be 16 years old to use this type of vehicle.
A pedestrian-controlled vehicle is where the operator walks with but doesn’t ride on the vehicle. You don’t need a licence to operate one.
