Driving Safety for Older Adults
By Anne Riddering, OTR/L, CLVT, COMS
Driving is an extremely complex everyday task. There are visual, cognitive (thinking, judgment, reasoning, remembering) and physical demands of driving that require the older adult driver to attend to a rapidly changing environment outside of the car. As the car moves through the environment, the driver must react quickly, often to unexpected events, such as pedestrians crossing in the middle of the road, the unexpected stop or turn of another vehicle, or an animal running into the road.
Contrast Sensitivity and Driving
Contrast sensitivity refers to the ability to detect differences between light and dark areas; therefore, increasing the contrast between an object and its background will generally make an object more visible. Usually, the strongest contrast is black-on-white or white-on-black. Seeing curbs and faded road surface markings are examples of low-contrast driving activities. Rain, snow, and fog (see photo at left) can also create a low-contrast driving environment.
Glare Sensitivity and Driving
Glare sensitivity (see photo at left) is another problem for many older adult drivers, during both day and night. By keeping your windshield, other car windows, and your eyeglasses clean, you can help to prevent some glare. Smudges, streaks, and dirt will often refract light at odd angles and will create more glare.
When the light from oncoming cars shines directly in your eyes, you should look slightly down and to the right of the road. You will be able to see the road using your peripheral vision which is less sensitive to glare.
Sunglasses may also help to reduce glare, especially those with a yellow or amber tint, which tends to increase contrast without darkening the environment. A yellow tinted lens may help on cloudy, rainy, or snowy days, or at night. Only a yellow tinted lens should be used for night driving.
Scanning and Driving Safety
Individuals with minimal vision problems who continue to drive should learn to scan in an organized manner. You can practice scanning when you are a passenger in the car. Begin at the left side of the road. Quickly scan horizontally across the road, looking for oncoming traffic, traffic lights, and pedestrians on sidewalks or corners. You can learn more about efficient horizontal scanning techniques at Scanning Efficiently for Activities of Daily Living.
Also, learn to pay close attention to the “Walk/Don’t Walk” signals. If the “Walk/Don’t Walk” signal is blinking, indicating don’t walk, be prepared to stop as the light could be changing soon.
Suggestions for Road and Driving Safety
To stay safe on the road, older adults can implement the following suggestions:
- Know the environments and situations that make you uncomfortable. Certain types of weather or busy roads may be distressing for you. Avoid these situations or environments, if possible.
- Stay in the right-hand lane as much as possible. Use familiar routes and stay close to home.
- Drive in the daytime if you are bothered by night glare. Avoid dusk hours, which create low-contrast driving situations.
- Avoid heavy traffic times, such as rush hour or around the time of school dismissal. Mid-morning or mid-afternoon may be a time when there is not as much traffic on the road.
- Identify and eliminate distractions. Turn off the radio. Don’t use your cell phone. Don’t eat, drink, or smoke in the car. Limit the number of passengers in your car.
- Plan your routes ahead of time. Think about the traffic on the roads you will drive. Consider where and in what direction you will turn. Have an alternative route in case of construction or when an accident closes lanes or the road.
- Maintain an appropriate speed and drive no slower than five miles per hour below the posted speed.
- Participate in a regular exercise program in order to maintain or increase mobility of your neck and trunk, your coordination, and your overall endurance.
- Explore local alternatives to driving. Senior and community centers may offer a door-to-door transportation service. Taxi services may offer discounts to older adults. Churches or neighborhood groups may organize volunteer drivers for older adults. These alternatives may come in handy if you need to get to an appointment scheduled at rush hour or during winter weather.
