What Size Motorbike Can I Ride With a Car Licence?

If you already hold a full car licence and fancy adding two wheels to your life, you don’t have to start entirely from scratch. Here is exactly what size motorbike you can ride with a car licence in the UK.

What Can You Ride on a Car Licence Alone?

With a full UK car licence, you can ride a 50cc moped in some cases without L-plates or a moped test, provided you obtained your car licence before 1 February 2001. If you passed after this date, you’ll still need to complete CBT before riding any moped or motorcycle, regardless of engine size.

Riding a 125cc Motorbike on a Car Licence

To ride a 125cc scooter or motorbike with a car licence, you need to complete Compulsory Basic Training (CBT). Once completed, you can ride a motorcycle up to 125cc and 11kW with L-plates displayed, no motorway riding, and no pillion passengers, for up to two years before your CBT certificate expires.

Pre-2001 Car Licence Holders: Special Rules

If you obtained your full car licence before 1 February 2001, your licence includes provisional entitlement to ride a moped without L-plates and without a CBT certificate. This is a legacy rule that only applies to those specific pre-2001 licence holders, so always check your licence for category P if you fall into this group.

What a Car Licence Does NOT Cover

  • Motorcycles above 125cc: you’ll need to pass a full A1, A2, or Category A motorcycle test.
  • Riding without L-plates on a 125cc (post-2001 licences): a full motorcycle test is required to remove this restriction.
  • Motorway riding on a CBT-only entitlement: motorways remain off-limits until you hold a full motorcycle licence.

Frequently Asked Questions

Can I ride a 125cc with just a car licence?

Yes, but only after completing CBT, and you must display L-plates and avoid motorways and pillion passengers.

Does a car licence let me ride any moped without a test?

Only if you obtained your full car licence before 1 February 2001. Everyone else needs to complete CBT first, regardless of moped engine size.

Can I carry a passenger on a 125cc with just CBT?

No, pillion passengers are not permitted while riding on CBT entitlement alone, regardless of your car licence status.
