Who needs to take a Vocational theory test?
You will need to take a theory test if you want a licence for a new category of vehicle, for example, if you have a car licence and you want a bus licence you will need to take a theory test. To upgrade within a vehicle category you will not normally have to sit the test, for example, if you have a category C licence (rigid body lorry) and you want a C + E licence (articulated lorry) you will not have to take a theory test. You will however have to take the relevant practical test. Anyone with sub-categories C1 and D1 entitlement who obtained those categories when they passed their car test and wants to upgrade to a C or D licence will have to obtain the correct provisional entitlement and pass a theory test. Please check with the Driver and Vehicle Licensing Agency (DVLA) or the Driving Standards Agency (DSA) if you are unsure if you should take a theory test.
