Being independent and being able to drive is a huge freedom for most people. However, there is a point where people of a specific age should be tested on whether they are free to be on the road and operating a vehicle. Various disabilities such as Dementia and Alzheimer's disease can often be present in people early on and are caught later in life when the disability becomes more severe. Those who suffer from these disabilities will have early on problems like remembering little details which can be a concerning danger to other people on the road. 

As people age, reaction time and processing are delayed 2-6 milliseconds per decade. Though this data may not seem alarming to most, in just two seconds of being distracted from the road the chances of getting in a life-threatening accident are doubled. Driving in heavy traffic or work zones, and during inclement weather or at night may become more challenging for older drivers. With this being said, drivers aged 70+ have higher crash death rates per 1,000 crashes than middle-aged drivers (ages 35-54). Higher death rates in those aged above 60 are primarily due to increased vulnerability to injury in a car crash. The older a person is, the weaker your muscles become along with your bones becoming more fragile and more susceptible to being easily broken.

A cutoff in age should be put in place for all people over the age of 65 (when these types of issues start arising) to where they are required to take a test that would check if their reaction time, awareness, and spatial reasoning are all adequate. Along with this a test of the basic rules of the road to reinforce the main ideas of driving. With this test in place, early symptoms of various disabilities could be caught or on the contrary basic driving skills could be reviewed leaving everyone on the road in more secure situations.
