Make sure that you can legally teach people to drive.
If people are paying you for lessons then you must be on the Driving Standards Agency’s Register of Approved Driving Instructors (ADIs). Even if they are just paying for the petrol you use you will be breaking the law if you are not an ADI.
Find out about becoming an ADI or renewing your registration on GOV.UK.
Make sure your driving licence is valid, and make sure you report any motoring or non-motoring cautions or convictions to DSA – these may affect your licence to teach.
Display your ADI certificate in the passenger-side edge of the front windscreen when you’re teaching – this is a legal requirement.
