What are the eyesight requirements to drive?

Q575: Is there anyway I can find out who the owner of a car is?

The police will not pass on any information about a vehicle owner's details, unless they are talking to the owner. In addition, there are very limited circumstances on when the DVLA will release such information to a person who is not the owner of the car.

Please see the 'FORM V888' link under Web Sites in Related Information, which takes you to the appropriate explanatory notes and application form.
