The main difference between an Approved Driving Instructor (ADI) and a Trainee Driving Instructor (PDI) is their level of qualification and experience.

Here’s a breakdown:

1. Approved Driving Instructor (ADI)

✅ Fully Qualified – Has completed all three parts of the DVSA instructor qualification process.                   

✅ More Experienced – Has likely spent more time teaching learners.
✅ Recognized by DVSA – Listed as an official instructor.
✅ Green Badge – Displays a green badge in the car window.

Pros of Choosing an ADI:

• Fully trained and experienced.
• Can provide structured lessons with a tested teaching approach.
• More likely to help you pass efficiently.

2. Trainee Driving Instructor (PDI)

🛠️ In Training – Has passed the first two tests but is still working on the final qualification.
🛠️ Limited Experience – May not have as much teaching practice.
🛠️ Licensed to Teach Learners – Can provide lessons but is still being assessed.
🛠️ Pink Badge – Displays a pink badge in the car window.

Pros of Choosing a PDI:

• Sometimes offers cheaper lessons.
• Still trained, but may not have as much experience as an ADI.
• Could be more motivated to help learners as they gain experience.

Which Should You Choose?

• If you want a highly experienced instructor, go for an ADI.
• If you’re looking for lower-cost lessons and don’t mind a less experienced teacher, a PDI can still be a good option.
