Most
older drivers will agree to limit or stop driving after patient,
caring conversations with family members. If the driver refuses
to comply, you may need to enlist the support of a doctor or driver
rehabilitation specialist for a formal driver assessment.
If you feel that safety is seriously compromised, you may have to take unilateral action, such as contacting the motor vehicle licensing authority.
If the older driver has dementia, families should be vigilant about observing driving. Dementia will eventually rob the driver of necessary skills and diminish insight into driving ability.
