One of the most important — and contentious — conversations between adult children and their parents often focuses on whether an older driver should give up the car keys.

Sometimes, the reasons are concerns over cognitive or physical problems. Other times, it's a growing litany of small accidents or close calls that spark a crisis. In some cases, the older driver can help ease worries by agreeing not to get behind the wheel at night, in bad weather or during heavy rush-hour traffic.
