Elderly drivers can pose a risk to themselves and their passengers, so some Coloradans want to see them get driving tests, coaching, and in some cases put down the keys altogether. It's getting more important to address the issue because the number of drivers 65 and older is growing fast.
But there's a risk of getting people off the road too soon, because it may lead to depression and even early death, according to Emmy Betz, an associate professor at the University of Colorado School of Medicine. She tells Colorado Matters host Ryan Warner that doctors should talk regularly with older patients about when to stop driving.
