Because everyone ages differently, some drivers are safe behind the wheel well into their eighth or ninth decade, while others need to find other sources of transportation much earlier. Some key risk factors for senior drivers follow.
Risk Factors of Aging That Can Affect Driving Ability:
Visual decline
Vision declines with age, which means depth perception and judging the speed of oncoming traffic become more difficult. The eyes also lose the ability to process light, which makes night vision worse and causes more sensitivity to bright sunlight and glare. By age 60, you need three times the amount of light that you did at age 20 in order to drive safely after nightfall (AgeNet.com).
Hearing loss
Approximately one-third of adults over age 65 are hearing-impaired. Because hearing loss happens gradually, seniors may not realize they are missing important cues when driving, such as honking, emergency sirens, or a child's bicycle bell.
Limited mobility and increased reaction time
With age, flexibility may decrease as response time increases. A full range of motion is crucial on the road. In addition, chronic conditions can limit mobility (rheumatoid arthritis, Parkinson's disease, sleep apnea, heart disease, or diabetes).
Medications
People often take more medications as they age. Certain medications, as well as a combination of medications and alcohol, can increase driving risk. Be particularly careful about medication side-effects and interactions between medications.
Drowsiness
Aging can make sleeping more difficult, resulting in daytime tiredness and an increased tendency to doze off during the day (or while driving). In addition, certain prescription drugs cause drowsiness.
Dementia or brain impairment
Mental impairment or dementia makes driving more dangerous and more frustrating. Brain impairment may cause delayed reactions to sudden or confusing situations on the road.
In addition, numerous environmental factors that affect people of all ages can magnify a senior’s diminished ability to drive safely:
signs and road markings that are difficult to see or to read
complex and confusing intersections
older vehicles that lack automatic safety features
newer dashboard instrument panels with multiple displays
Warning signs of unsafe driving are
If a senior who is close to you is finding driving more difficult than before, watch for signs of unsafe driving. If you notice any of the warning signs, it is time to reassess the senior’s road risk. Many small warning signs of unsafe driving can add up to the important decision to quit driving.
Some Warning Signs of Unsafe Driving are:
Abrupt lane changes, braking, or acceleration
More frequent "close calls" (i.e., almost crashing), or dents and scrapes on the car or
on fences, mailboxes, garage doors, curbs, etc
Failing to use the turn signal, or keeping the signal on without changing lanes
Drifting into other lanes
Driving on the wrong side of the road or in the shoulder
Trouble reading signs or navigating directions to get somewhere
Missing highway exits or backing up after missing an exit
Range-of-motion issues (in looking over the shoulder, moving the hands or feet, etc.)
Trouble moving the foot from the gas to the brake pedal, or confusing the two pedals
Feeling more nervous or fearful while driving or feeling exhausted after driving
More conflict on the road: other drivers honking; frustration or anger at other drivers
Oblivious to the frustration of other drivers, not understanding why they are honking
Reluctance from friends or relatives to be in the car with the senior driving
Getting lost more often
Trouble paying attention to signals, road signs, pavement markings, or pedestrians
Slow reaction to changes in the driving environment
Increased traffic tickets or "warnings" by traffic or law enforcement officers
Some steps to take if you are concerned about the safety of a senior driver include
If you are concerned about an elderly driver, closely monitor their driving before deciding whether they need to brush up on their driving skills or give up their driver’s license altogether. Some steps include:
Watch for changes in driving habits, general behavior, and health.
Encourage a driving evaluation through your local Department of Motor Vehicles, along with refresher driving lessons and the
AARP Driver Safety course.
Explore ways to reduce driving, such as making purchases online or through mail-order catalogs. If possible, arrange for home delivery of groceries, and home visits by clergy, medical and personal care providers, and government service providers.
If necessary, garner support from the older adult's primary care physician and other family members.
Talking to a senior driver who should stop driving
If you feel that it is time to talk to a senior close to you about stopping driving, approach the issue with sensitivity. A driver’s license signifies more than the ability to drive a car; it is a symbol of
freedom
independence and independent living
self-sufficiency
being employed
fun and spontaneity
involvement in social and religious activities
Understandably, driving is not a privilege that anyone—teenager or elder—wants to relinquish willingly. As important as it is to treat the senior driver with respect and not jump to unjust conclusions, it is also important to help the elderly driver retire from the road.
Start slowly and try to persuade the senior to give up the keys. Some approaches that may work:
Be understanding about resistance. The senior may dismiss you and refuse to listen to you. Emotion may get in the way of a rational decision.
Ask questions, rather than make demands. For example, “Would you consider not driving at night?”
Talk about safety considerations. Many senior drivers who shouldn’t be driving have already had an accident or some close calls. Remind the impaired driver of the danger of serious injuries and that the safety of others is also at risk.
Explain transportation options. Help the senior driver see that living without a car won’t make them permanently homebound.
Acknowledge the lifestyle change, but also show them how to continue favorite activities and to remain mobile.
Emphasize monetary savings. The cost savings associated with giving up a car may be a selling point for some older drivers. Costs include insurance, gasoline, maintenance and repairs, and license and registration fees.
Offer rides and visits. Volunteer to come by once a week or to provide rides on a regular basis for things like grocery shopping, library visits, or doctors’ appointments.
Seek confirmation of the situation.
Some elderly drivers may be aware of their faltering ability, but be reluctant to give up driving completely. Another person’s concerns may force the senior driver to act.
They may even feel relieved to have someone else help make the decision to stop driving.
