Driving Assessment for Elderly Parent: When and How to Get One

You've noticed the dents, the close calls, the wrong turns on familiar routes. But "I think Mom shouldn't drive anymore" isn't a conversation that goes well without evidence. A professional driving assessment gives you objective data — and if the result says your parent is unsafe, it transfers the judgment from you to a credentialed evaluator. That shift matters enormously in families where the parent refuses to listen to their children.

The Three Types of Assessment

Office-based physician screening is the fastest and cheapest option. Your parent's primary care doctor administers cognitive tests — the Montreal Cognitive Assessment (MoCA), Trail Making Test Part B, or Clock Drawing Test — during a regular appointment. A MoCA score of 18 or below, or an inability to complete the Trail Making Test Part B within three minutes, is considered an immediate clinical indicator for driving retirement.

The physician can also review medications for side effects that impair driving — drowsiness, slowed reflexes, blurred vision — and check physical function: neck rotation for blind spots, grip strength, reaction time. The appointment costs a standard co-pay under Medicare or private insurance, typically $15–$50.

Certified Driver Rehabilitation Specialist (CDRS) evaluation is the gold standard. A CDRS conducts a comprehensive two-part assessment: a clinical screening (vision, cognition, physical function) followed by an on-road driving test in a specially equipped evaluation vehicle. The CDRS observes how your parent handles real traffic, lane changes, intersections, and unexpected situations.

CDRS evaluations cost $300–$800, are almost always out-of-pocket, and are not covered by Medicare or most insurance plans. But the investment is often worth it because the result carries authority with DMV medical review units, insurance companies, and resistant family members. Some occupational therapy practices that employ a CDRS can bill the clinical portion under OT codes, reducing the out-of-pocket cost.

Find a CDRS through the Association for Driver Rehabilitation Specialists (ADED) directory or ask your parent's occupational therapist for a referral.

DMV driver reexamination is triggered by a report from a physician, law enforcement officer, or family member. In mandatory reporting states like Pennsylvania and California, physicians are legally required to report patients with conditions that impair driving — including dementia, seizure disorders, and significant vision loss. In voluntary states, reporting is discretionary, and family members may need to use the state's reporting process.

The DMV reexamination typically includes a written knowledge test, a vision screening, and sometimes an on-road driving test. If your parent fails, the state can restrict or revoke their license. The process takes weeks to months depending on the state.

Which Assessment to Pursue

If your parent is cooperative and willing to discuss driving safety, start with the physician screening. It's low-cost, it's within the context of a routine medical visit, and it provides the baseline cognitive and physical data you need. If the physician identifies concerns, they can refer to a CDRS for a definitive road test.

If your parent refuses to discuss the topic and you're worried about immediate safety, you have two paths. In mandatory reporting states, ask your parent's physician to fulfill their reporting obligation — the DMV process begins without your parent needing to agree. In voluntary states, family members may need to act directly; check the DMV's Medical Review Unit for the state's reporting and confidentiality rules. California uses Form DS 699. Wisconsin uses Form MV3141. Filing options and confidentiality rules vary by state, so follow the relevant DMV's instructions.

If you need objective evidence to resolve a sibling disagreement — one sibling says Dad is fine, another says he's dangerous — the CDRS evaluation provides the most authoritative answer. The report is detailed, defensible, and hard to dismiss.

What Happens After a Failed Assessment

A failed physician screening doesn't automatically revoke a license. The physician may recommend driving cessation, refer to a CDRS, or file a mandatory or voluntary report with the DMV. Your parent can choose to stop driving voluntarily, continue driving against medical advice (which leaves the safety risk unresolved), or request a CDRS evaluation for a second opinion.

A failed CDRS evaluation is harder to ignore. The specialist may recommend immediate cessation, restricted driving (daytime only, familiar routes only), or vehicle modifications. The report can be shared with the DMV and may trigger a formal license review.

A failed DMV reexamination results in license restriction or revocation. Your parent has the right to appeal, which usually involves an in-person hearing and may include a new road test. But once the DMV has acted, continuing to drive with a revoked license can carry additional penalties under state law.

After the Keys Are Gone

The assessment is step one. Step two is replacing the car with a reliable alternative — ADA paratransit, Medicaid NEMT, volunteer driver programs, and rideshare services that don't require a smartphone. The Transportation Solutions for Non-Driving Parents toolkit covers the full transition: from the initial observation period through clinical evaluation, legal liability protection, and building a weekly ride schedule that keeps your parent mobile, connected, and safe.

The hardest part of this process isn't the assessment itself. It's what comes after — the conversation, the grief, and the logistics. But families who approach it with objective data, rather than opinions, consistently report less conflict and faster resolution.
