Q: How would it be illegal for a provisional licence holder to drive?
Explanation
When driving a motor car, a learner driver who holds a provisional driving licence must do all of the following: display red L plates (or D plates in Wales) to the front and rear of the vehicle; be insured to drive the vehicle; be accompanied by someone who's at least 21 years old and who has held for at least three years (and still holds) a full licence for the category of vehicle being driven.
