The driving licence category B1 means that you can drive motor vehicles with 4 wheels (light vehicles and quad bikes) up to 400kg unladen or 550kg if they’re designed for carrying goods.
F stands for agricultural tractors. K stands for mowing machine or pedestrian-controlled vehicle. P stands for mopeds with an engine size not more than 50cc, with a maximum speed of over 45km/h but not more than 50km/h. Its engine size must not be more than 50cc if powered by an internal combustion engine.
Having a B on your licence allows you to drive a motor vehicle with up to eight passenger seats only. To drive a minibus with 9 to 16 seats with or without a trailer (weighing no more than 750kg), you would need a D1 on your driving licence.
If you need a trailer weighing more than 750kg you need a D1+E, and the total weight of the vehicle and trailer may be no more than 12,000kg.
Additionally, the minimum age to drive a minibus is 21. Certain exceptions exist which may allow someone as young as 17 to drive a minibus, such as being a member of the armed services.
See other conditions you must meet before you can drive a minibus at GOV.UK.
You won't be needing a driving licence for electric bikes, mobility scooters or powered wheelchairs.
