title: Relationship Between Cognitive Perceptual Abilities and Accident and Penalty Histories Among Elderly Korean Drivers.
abstract: OBJECTIVE
  To investigate the relationship between cognitive perceptual abilities of elderly drivers based on the Cognitive Perceptual Assessment for Driving (CPAD) test and their accident and penalty histories.
  
  
  METHODS
  A total of 168 elderly drivers (aged ≥65 years) participated in the study. Participant data included CPAD scores and incidents of traffic accidents and penalties, attained from the Korea Road Traffic Authority and Korea National Police Agency, respectively.
  
  
  RESULTS
  Drivers' mean age was 70.25±4.1 years and the mean CPAD score was 52.75±4.72. Elderly drivers' age was negatively related to the CPAD score (p<0.001). The accident history group had marginally lower CPAD scores, as compared to the non-accident group (p=0.051). However, incidence rates for traffic fines did not differ significantly between the two groups. Additionally, the group that passed the CPAD test had experienced fewer traffic accidents (3.6%), as compared to the group that failed (10.6%). The older age group (12.0%) had also experienced more traffic accidents, as compared to the younger group (2.4%).
  
  
  CONCLUSIONS
  Overall, elderly drivers who experienced driving accidents had lower CPAD scores than those who did not, without statistical significance. Thus, driving-related cognitive abilities of elderly drivers with insufficient cognitive ability need to be further evaluated to prevent traffic accidents.
