What is DVSA ADI (Approved Driving Instructor)?

An Approved Driving Instructor (ADI) is an individual registered with the Driver and Vehicle Standards Agency (DVSA) who is legally permitted to charge for car driving tuition in Great Britain. ADIs display a green octagonal badge in the windscreen; trainee instructors with a Potential Driving Instructor (PDI) licence display a pink triangular badge and may give paid tuition only while supervised or within set hours. The ADI register can be verified at check.vehicle.service.gov.uk. The ADI qualifying process involves three tests: theory and hazard perception, driving ability, and instructional ability. ADIs must undergo periodic check tests and continuing professional development to remain on the register.
