ADI vs PDI
You have probably seen both terms when searching for a driving instructor and wondered what the difference actually is.
An ADI is an Approved Driving Instructor.
They have:
🟢 Passed all three DVSA qualifying exams
🟢 Met the required national teaching standard
🟢 Been assessed for instructional ability
🟢 A green badge displayed in the windscreen
An ADI is fully qualified and regularly standards checked to make sure their teaching remains at the required level.
A PDI is a Potential Driving Instructor.
They have:
🟣 Passed the first two DVSA exams
🟣 Permission to teach while training
🟣 Not yet passed the final instructional ability test
🟣 A pink badge in the windscreen
A PDI is still in training and working towards full qualification.
There is nothing “wrong” with learning with a PDI. Many are excellent and dedicated.
The key difference is experience, qualification status and assessment level.
When choosing an instructor, ask:
• Are you fully qualified?
• Do you display a green or pink badge?
• How long have you been teaching?
Driving is not just about passing a test.
It is about being taught correctly, safely and confidently from the very beginning.
Always check the badge in the windscreen.
