Mild Cognitive Impairment in an Older Driver Living Alone
Mrs. L is a 76-year-old widow who lives alone in a single-family home. She has amnestic mild cognitive impairment (CDR 0.5, MoCA 23/30) and hypertension. She still drives 10 to 15 minutes to church, the pharmacy, and the grocery store two or three times a week. Her daughter reports two low-speed parking lot collisions in the past 8 months and says Mrs. L got lost once on a familiar route. Mrs. L denies any problem and says, 'I have driven for 58 years.' She has 20/25 acuity, full visual fields, no neglect, and no motor deficits. Her neurologist has not restricted her. The state has permissive reporting for physicians and no mandatory reporting for driver rehabilitation specialists. She refuses to stop driving and becomes tearful when the topic arises.
1. How would you structure the fitness-to-drive assessment for Mrs. L, and what would you tell her at the outset?
Read the worked answer
I would frame the assessment as a functional evaluation, not a memory test or a punishment. At the outset I would explain the limits of confidentiality, including that I may need to share safety concerns with her physician or licensing authority under the state's permissive reporting framework. I would assess insight separately by asking her to explain the two collisions and the getting-lost episode; denial despite concrete events is itself relevant. The clinical battery should include repeat cognitive screening, attention and divided-attention tasks, visual scanning, reaction time, and a behind-the-wheel evaluation in a dual-brake vehicle on familiar and unfamiliar routes. The daughter's report is collateral evidence, not proof, and should be documented as such. I would tell Mrs. L that the goal is to preserve her independence as long as it is safe, and that the on-road result, not her age or diagnosis, will drive the recommendation.
2. Given the findings, what recommendation and monitoring plan would you make? Include restrictions and review intervals.

The two low-speed collisions plus one getting-lost episode in a driver with amnestic MCI create a high index of suspicion, but MCI alone is not an automatic disqualification. If the on-road evaluation shows unsafe lane position, poor hazard detection, or route-finding errors, I would recommend driving retirement. If she passes narrowly, I would recommend a restricted license: daylight only, familiar routes within a 5-mile radius, no freeway, no unfamiliar destinations, and a passenger when available. Review would be at 3 months initially and every 6 months thereafter, with repeat cognitive and on-road testing. I would also involve her daughter in a family meeting and arrange alternative transportation, because a restriction without a practical alternative is likely to fail. If she continues to drive unsafely despite counseling, I would document the specific risks and consider a voluntary report to the licensing authority with her knowledge, consistent with state law.
3. What are your reporting obligations and how would you document the decision?
Read the worked answer
In this state, reporting by a driver rehabilitation specialist is permissive, not mandatory, so the legal obligation is limited; the ethical obligation is not. I would document the collision history, the getting-lost episode, the MoCA and CDR scores, the on-road findings, her denial, and the counseling provided. I would state clearly whether she was told the recommendation and whether she understood the consequences. I would contact her neurologist with her consent to share the evaluation and ask whether reversible factors, such as medication effects or depression, have been addressed. If she continues to drive against advice and presents an imminent risk, I would explain that I may make a voluntary report to the licensing authority and give her the opportunity to participate. The record should avoid labels such as 'demented' and should describe observable behavior and test performance. This protects her autonomy, supports the family, and creates a defensible rationale for whatever action is taken.
