  • Becoming lost when taking a familiar route.
  • Appearance of new scratches and dents on the car.
  • Getting ticketed for a driving violation.
  • Getting into a car accident, or having a near-miss.
  • Receiving a recommendation from a doctor to stop or reduce driving, having health problems that impact driving, or taking medications that affect driving.
  • Finding that road signs and road markings are suddenly overwhelming.
  • Driving too fast or too slowly for no apparent reason.
