Who Are the Medically at Risk?

Just because someone is old, does not necessarily make them an at-risk driver.  In fact, the research shows that older adults are generally safe drivers (1) and it is not until advanced aging crash rates significantly increase (2). 

However, with increasing age, there are increased medical conditions that impact driving capacities. Thus, it is not older drivers per se that are unsafe, it is the medically at-risk driver that needs to be identified and supported through appropriate evaluation and intervention.  A medically at-risk driver can be any age, although, certainly, older adults have increased conditions, such as dementia or other cognitive impairments.


What we do know about older drivers. 

  • Older drivers are generally safe drivers (1). 
  • As one ages, drivers tend to self restrict (3).
  • We all age differently 

HOWEVER…. 

  • Clear evidence: with aging: increased processing speed.
  • We will outlive our ability to drive!
  • Men – 6 years 
  • Women – 10 years

Why is driving such an issue for older adults? 

  • Many older adults live in suburban & rural areas (8).
  • Driving will remain the primary choice and personal mode of transportation (1,9).
  • Decision to stop driving has adverse consequences (10-11).
  • Older adults want to age in their communities (12).
  • Want and need to continue driving to maintain health & quality of life (12).
