A motorcycle with an engine capacity of under 50cc is classed as a moped. Learner moped riders must undertake a compulsory basic training course before they can ride on the road. This is a legal requirement specified in the Road Traffic Acts. Once a course has been successfully completed, a rider is issued with a certificate. The Driver and Vehicle Licensing Agency will update the rear of the persons photocard licence on successful completion of the course to show code 122. Any persons riding on the road who ignore this training requirement are committing an offence and are liable to prosecution.
