> Once you get a license you never get retested for vision or driving ability If you are in California, you will occasionally be required to go to an office in-person for DL renewals where your vision will be tested as part of the process. Many insurance companies also incentivize older drivers taking "mature driver improvement" courses every few years as a refresher. Then of course there's things like traffic school if you are driving and receive a moving traffic violation. This seems straightforward... Also, I might note this because I went through this process with my father... when your vision is bad enough to fail the DMV's criteria of 20/40 corrected vision with either or both eyes, they have a whole load of things they make you do. With my father he could theoretically hit the 20/40 vision requirement but made mistakes due to scarring from surgeries that blurred vision in only certain areas. He had to get documentation from his doctor as to what kind of driving he could potentially do (e.g. no night driving), got additional mirrors installed in the car, went through a special drive test (after he did his own refresher driving class voluntarily), and had a whole load of restrictions added to his already limited term license (e.g. he had to get a new license after only a couple of years, and every renewal would require a drive test). In the end, it was such a hassle despite zero functional issues driving that he ended up giving up his DL at the last renewal. If his vision had declined significantly from there, DMV would have immediately revoked the license and suspended his ability to receive a new one. So, sure, seniors and teens alike cause a lot of accidents, but we're not exactly lacking on trying to reduce problems.
