When it comes up to the decision of giving up your keys, people can typically encounter powerful emotions.
Driving usually means mobility, independence, and control over your own life. Losing that control can trigger depression, and sometimes reduce the involvement in social activities.
As an older driver, you can remain mobile by adjusting your driving habits. For example, driving in daylight hours only, and driving during off-peak office hours. Try driving only on familiar roads with lower speed limits, and taking shorter trips. By adjusting your driving habits, you are minimizing the risk of getting into an accident.
