The CBT gives you a basic understanding of motorcycle skills, it lets you ride on L plates but you can't take a pillion or go on a motorway and it has a life of 2 years.

If you don't pass a motorcycle test in this time you need to retake the CBT course.

Full UK Car licence holders

On a full UK car licence, a CBT certificate (DL196) allows you to ride a motorcycle up to a maximum of 125cc, either automatic or manual, with a power output of no greater than 14.6 bhp (11 kW). You have to display L-plates and you may not take passengers. You are not allowed to ride on motorways.

However, if you only want to ride a 50cc moped and you gained your full car licence before February 2001, you do not need to complete CBT, but it would be very worthwhile doing so. You will be a lot safer on the road. You may carry passengers and you do not need to display L-plates. A moped is defined as a motorcycle with a maximum design speed not exceeding 31 mph and with an engine capacity not exceeding 50cc.  If you want to ride a moped and gained a full car licence after February 2001 you may not ride on the road until you have obtained a CBT certificate.

Provisional UK licence holders

On a provisional UK car licence, a CBT certificate (DL196) allows you to ride a motorcycle up to a maximum of 125cc, either automatic or manual, with a power output of no greater than 14.6 bhp (11 kW), providing you have valid provisional motorcycle entitlement (Category A) on your licence. You have to display L-plates and you may not take passengers. You are not allowed to ride on motorways.

If you do not have provisional motorcycle entitlement on your licence and only have provisional moped entitlement (Category P) then you may only ride a moped once you have completed CBT. A moped is defined as a motorcycle with a maximum design speed not exceeding 31 mph and with an engine capacity not exceeding 50cc.

        To tell if you have provisional motorcycle entitlement                         (Category A) and you have the photocard licence, turn over         the photocard and it will list all the provisional categories you         have on the back of it (provisional licence holders only).  At             age 16, you will only have provisional moped entitlement.  If             you have the old style paper provisional licence, your                     Category A most probably has expired and you will need to             renew it.  If you are not sure about your licence and require             further information, please go to the DVLA website or call                 them on 0300 790 6801.

  The five elements have to be               completed in sequence, although  
  the order of the exercises within the   element can be varied. You will only     move on to the next element when       your instructor is satisfied you have     learnt the necessary theory and           demonstrated the practical skills to a     safe basic level. Trainees must, by       law, receive a minimum two hour           on-road ride in Element E.

After CBT, you must take the Theory Test prior to further training and Practical Test.
