Elderly Drivers

Every time I drive down the road and see an elderly driving, I always get nervous and will find myself observing how they drive. I start thinking about wether he/she can see or hear clearly and wonder about how easy it would be for such a person to get into an accident. However, as much as I am worried about elderly drivers, I don't think there should be a mandatory state test to evaluate their driving. Such a test I feel, would be demeaning and embarrassing.
Demanding for elders to get mandatory testing for driving would be the opposite of testing for your license for the first time. Instead of feeling a sense of accomplishment and proud of reaching a stage of maturity, you would feel as if you're not worthy or good enough to be allowed to drive. I think it would crush their spirits and make them feel like they are losing their independence.
On the other hand, I'm not saying that elders who are losing their senses and motor skills should be allowed to drive until something bad occurs, but instead to leave the testing and evaluation up to the doctors and families who know that the person the best. It should be up to the families and doctors to asses a senior's health and determine whether he/she is capable of driving. It also should not be a one time test done after the age of 65. Even if an elder is fine and healthy this year, things can change drastically by the next year. Elder driver evaluation should always be a concern and an ongoing task for their primary care providers.
