Mandate drivers license test's to be retaken every 3 years after the age of 60

After the age of 60 your body slows down your reaction time slows, your eyes become weak. You thoughts and thought processes change and slow as well. Driving is a task that requires reaction time and good thought process. After the age of 60 you begin to loose that. I suggest license retakes after the age of 60 every 3 years because it will cut down on accidents with the elderly who shouldn't be driving as well as create job opportunities at the local DMV. Every year your body slows and in three years time it can be completely different. Elderly drivers are a hazard to other drivers. If they can't pass the test the license should be revoked
