Ok today is my birthday. Im 69. In Arkansas your drivers license expires on your birthday. I had a class A CDL that was good for 4 years. Been driving dig trucks since I bought one when I was 16. I know that my semi truck driving days are over. I have no business hurtling down the road in a 80,000 pound truck. So I did not renew my CDL I just got a regular Drivers License. That License is good for 8 years. I don't like that. As we get older our mental as well as our physical condition declines. I think its better to err on the side of caution. My opinion is once we reach retirement age 62 that driving license needs to be renewed every two years and we need to take a driving test when we get it renewed. Once we get to be 70 we need to have to take both a written and driving test every year. Yet I see folks barley able to walk see or hear driving large RV,s and towing a vehicle or boat? Every couple of years I have to get new glasses because my eye sight declines. Of course Im saying this right now because im certain I could easily pass a written and driving test at this time. However in a few years I might have no business driving and then I will be Ok with not having to be tested on a regular basis. Of course at this moment I tell myself that a good driver knows when to stop driving. In 8 years my grandsons will be old enough to drive. I will let them chauffer me around.
