75% of people with dementia still pass driving tests. But neurologists strongly recommend that people who have even mild dementia stop driving.
Caregiver input and assessments are more reliable than patient ratings termed as “safe.” Caregiver concerns should prompt a doctor visit. They have a “duty to report” those who are too impaired to drive.
1. Decrease in the number of miles driven (the person knows they are not safe).
2. Avoidance of driving in certain situations, such as at night or in the rain.
3. Recent history of collisions, moving violations. This includes unexplained damage to the car.
4. Aggressive or impulsive personality traits or behaviors.
