This case and commentary explore health professionals' duties to advocate for individual patients, protect their communities, and navigate conflicts between them.

Mr P's state statute on physician reporting of impaired drivers states: "Drivers should self-report medical conditions that could cause a lapse of consciousness, seizures, etc.
