Functional tests for older drivers show decreasing predictive value for crash risk over time. Periodic reevaluation, ideally every two years, is crucial for effective screening and public safety.

Area of Science:

  • Gerontology
  • Traffic Safety Research
  • Public Health

Background:

  • Crash data scarcity poses challenges for analyzing older driver safety.
  • Previous analyses examined functional capacity and crash involvement for older drivers.

Purpose of the Study:

  • To update previous analyses with an additional year of driving data.
  • To assess the stability of functional test predictors for older driver crash risk.

Main Methods:

  • Updated analysis of functional capacity measures and at-fault crashes for older drivers.
  • Utilized odds ratio (OR) calculation to examine predictor-outcome relationships.
  • Contrasted peak OR values and examined stability of pass-fail cut-points.

Main Results:

  • The predictive accuracy of functional tests diminishes over time.
  • Perceptual-cognitive measures showed a particular decrease in predictive value.

Conclusions:

  • Periodic reevaluation of functional capacity screening is essential (intervals ≤ 2 years).
  • Effective screening by licensing authorities and healthcare professionals enhances public safety and reduces risk.
