A driver with a Category C1 licence is qualified to drive a vehicle over 3,5000Kg (C), but below 7,500Kg. This might include vehicles like:
Home/Supermarket Delivery Vehicles
Removal Trucks
Ambulances
Small horseboxes
These types of vehicles are also referred to as Class 3 or 7.5 tonne trucks. If you opt for a C1+E licence, the +E means that you can add a trailer over 750kg to the weight of any vehicle you are driving.
If you obtained your car licence (Category B), before January 1997, then you automatically have ‘grandfather rights’, which means you are qualified to drive C1 category vehicles, without upgrading your licence. Anyone who obtained their car licence after that date, and is medically fit to drive, can upgrade their licence to a C1 licence.
