5. Parkinson’s Disease and Limited Mobility
Diseases that affect movement, such as Parkinson’s, arthritis, or other musculoskeletal disorders, can severely impact coordination and reaction time. Turning the steering wheel, pressing the brake pedal, or checking blind spots may become difficult.
Stiff joints and muscle tremors can delay response times by even a few seconds — which, in traffic, can mean the difference between safety and disaster.
In early stages, adaptive driving equipment (such as hand controls or swivel seats) can help maintain independence. However, as the disease progresses, doctors usually recommend transitioning away from driving to avoid serious accidents.
