By age 65, hearing loss occurs to 39% of people. High sounds go first, making sirens difficult to hear. Background noises can significantly distort sound and interfere with your driving. A turn signal left on because you don’t hear it can cause a crash.

Because approximately 90% of the cues you get while driving come through sight, you must recognize and understand these age-related changes in vision: slower focusing, poor vision in dim light, difficulty seeing in bright sun or glare, reduced peripheral vision.

These changes don’t always show up on eye exams, but they do affect your ability to drive safely. Being able to see road signs and signals, other vehicles, and pedestrians is affected by more than just visual acuity.

• Keep your glasses, windows, mirrors, and headlights clean.

• Avoid driving at night and when visibility is poor.

• If you must drive at night, don’t wear sunglasses of any kind.

• Have your vision checked annually.

• Clean the inside and outside of windshield and windows.

• Clean headlights and mirrors.

• Give your eyes a few minutes to adjust to changes in light and dark. Use this time to fasten seat belt and adjust mirrors.

• If you can’t see over the steering wheel, sit on a cushion or pillow make sure you can still reach the gas and brake pedals.

Drinking alcohol impairs judgment, slows reflexes, distorts decision-making, and hinders coordination. And you don't have to be a problem drinker to have alcohol-related driving problems, because alcohol tolerance decreases with age. If you drink, don’t drive.

Both prescription and over-the-counter medications have side effects that can affect your ability to drive safely. Whenever you take any medication, ask your pharmacist or physician about driving.
