How to Ask a Doctor to Evaluate an Older Driver's Fitness

Why the Doctor Matters

When conversations with your parent about driving safety stall — and they usually do — the physician becomes your most powerful ally. A doctor's clinical authority carries weight that family concern alone doesn't. Your parent may dismiss your observations as worry or overreach, but a physician's recommendation to stop driving is harder to brush aside.

Beyond the persuasive power, doctors serve a practical function in the driving safety process. They can screen for the cognitive and physical impairments that make driving dangerous, refer to a Certified Driver Rehabilitation Specialist (CDRS) for a formal evaluation, and — in six states — are legally required to report certain conditions to the DMV.

The key is knowing how to communicate your concerns through proper channels and what to expect from the medical process that follows.

Sharing Your Concerns Confidentially

You don't need your parent's permission to contact their doctor with your observations. HIPAA allows one-way incoming disclosures — meaning a physician can receive information from a caregiver without the patient's consent. They just can't share the patient's medical information back to you without the patient's authorization.

The practical path: Send a detailed letter or secure message through the patient portal describing specific driving behaviors you've observed — with dates, locations, and descriptions. Faxing is also acceptable and creates a documented record. Include:

• Specific incidents (ran a stop sign on May 3, got lost driving home from the pharmacy on May 8)
• Observable changes (can't turn neck to check blind spots, slow pedal transitions, confusion at familiar intersections)
• Any recent accidents or near-misses
• Relevant behavioral changes (missed medications, difficulty with familiar technology, increased confusion)

The doctor can incorporate your observations into the next clinical encounter; HIPAA does not require your parent's authorization for the doctor to receive them, but it does not guarantee that the doctor will keep the contact undisclosed.

What the Doctor Can Do

In-office cognitive screening. Using tools like the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), or the Clinical Assessment of Driving Related Skills (CADReS), the doctor can assess the cognitive domains that driving depends on — attention, executive function, spatial processing, and reaction time. These screenings aren't driving tests, but they identify the functional deficits that make driving dangerous.

Physical assessment. The doctor can evaluate vision, neck range of motion, grip strength, ankle flexibility, and peripheral neuropathy — the physical systems that control steering, braking, mirror checking, and hazard response.

Referral for formal driving evaluation. If screening reveals concerns, the doctor can refer your parent to a CDRS for a comprehensive clinical and on-road evaluation. The physician referral carries clinical weight and may be required by the evaluation facility.

The "prescription" to stop driving. Some physicians will write a formal recommendation — effectively a prescription — for their patient to retire from driving. This shifts the authority from the family to the medical profession: "Your doctor says it's time" is a fundamentally different conversation than "Your kids think you should stop."

DMV reporting. In six mandatory reporting states — California, Delaware, Nevada, New Jersey, Oregon, and Pennsylvania — physicians are legally required to report specific, state-defined medical conditions to the DMV within state-specified timeframes. In all other states, physician reporting is voluntary but permitted.

The Mandatory Reporting States

If your parent lives in one of these states, the physician reporting pathway may be the most direct route to a formal driving review:

In mandatory reporting states, the physician — not you — becomes the reporting party, which can preserve your relationship with your parent while still initiating the DMV review process.

What Doctors Won't Do

Most physicians are reluctant to unilaterally "ban" a patient from driving. There are good reasons for this:

• Liability concerns. A doctor who tells a patient to stop driving and is wrong faces potential legal action. A doctor who doesn't tell them and an accident occurs also faces liability. This tension makes many physicians cautious and procedural rather than decisive.
• Relationship preservation. The physician-patient relationship depends on trust. Directly ordering a patient to stop driving — especially when the patient doesn't recognize their own impairment — can damage the therapeutic alliance and cause the patient to avoid medical care altogether.
• Scope limitations. Primary care physicians are not driving evaluators. They can screen for functional deficits and refer for evaluation, but a definitive determination of driving fitness is properly the domain of a CDRS.

This is why your communication to the doctor matters. The more specific and documented your observations, the easier it is for the physician to act clinically rather than relying on general impressions from a routine appointment where the patient is on their best behavior.

After the Doctor's Involvement

The physician's role opens the door to the formal processes that follow — the CDRS evaluation, the DMV medical review, and the family conversation grounded in clinical findings rather than opinion. None of these guarantee your parent will stop driving willingly, but they shift the conversation from subjective family concern to objective clinical evidence.

The Taking Away the Car Keys guide covers how to coordinate the physician communication with the broader driving retirement process — including the HIPAA-compliant communication channel, what to include in your observation letter, how to work with the doctor's findings in a family meeting, and what to do when the medical process alone doesn't resolve the situation.
