Who makes the decision whether you should drive or not?

In our state A doctor can make the recommendation to the state but the state makes the decision.

A Doctor can make that decision .

Usually the state makes the decision. If you think someone shouldn't be driving, you can report it to the state and ask them to check. An alternative is to ask the doctor to check and report it if appropriate.

For better or worse, if you are under guardianship from the courts, your guardian has the ability to make that decision for you.

Ultimately, though, the resident state grants a drivers license and the resident state can revoke it as well.

These are just two that determine who can and cannot drive.
