When should drivers over 70 consider stopping driving?

3. Heart and circulation: watch out for sudden episodes of dizziness

A brief dizzy spell… happening while  driving? Some cardiovascular issues, such as arrhythmias or high blood pressure, can cause dizziness, shortness of breath, or even fainting.

What helps:
Regular check-ups, a healthy lifestyle, and proper treatments. And most importantly: listening to your body. If you’re not feeling 100%, leave the car in the garage — without guilt.

4. Diabetes: when blood sugar affects your time behind the wheel

We don’t always think about it, but a hypoglycemic episode can cause blurred vision, trouble concentrating… or even loss of consciousness. And it can happen very quickl

A smart habit:
Always check blood sugar before driving, keep a snack on hand, and let someone know if you feel weak.

5. Reduced mobility: movement is also part of safety

Turning the  steering wheel, pressing the pedals, checking blind spots… driving requires fine coordination. Arthritis, joint pain, or conditions like Parkinson’s disease can limit movement and slow reactions.

Helpful options:
Car modifications exist (smoother steering, automatic transmission…), as well as physical therapy to maintain mobility. But if basic movements become truly difficult, it may be time to rethink mobility altogether.

Medications: those side effects that cloud your senses

Drowsiness, dizziness, reduced alertness… some medications — even common ones — can impair driving, especially when combined.
