If you feel you can no longer safely operate a motor vehicle, you can give up your driving privileges (i.e., grant of legal authority to operate a motor vehicle on publicly accessible roadways) and turn in your driver license at a local DMV office. You may qualify for, and be issued a free identification card if you meet all requirements and are relinquishing an unexpired Oregon driver license. Otherwise, you will have to apply for an identification card and pay the applicable fees.
Please note that if you give up your driving privileges but later want to reapply for them, you will need to obtain medical clearance from DMV. Then you must pass the vision screening, knowledge and drive tests, clear any suspension, revocation or cancellation actions on your driver record and pay original licensing fees.
