Abstract

With the increasing number of older drivers, road traffic safety is an urgent public health issue. It is not easy for older drivers or their relatives to detect early signs of dangerous driving behaviors. We examine the types of driving behavior that increase in frequency with age. We surveyed people aged 40 and over among the general public in Japan using a self-administered questionnaire on sociodemographic factors, driving status, frequency of driving, 12-items on physical symptoms possibly related to driving performance, and 28-items on driving behaviors. Multiple logistic regression models were used to estimate the odds ratios (OR) of occurrence of each of the 28 driving behaviors for a 5-year increase in age. Significant associations with a 5-year increase in age after adjusting for confounding factors were found for the following directly unsafe driving behaviors: (1) little or no sign of attempts to avoid dangerous situations (OR for a 5-year increase in age=1.38, 95% CI: 1.18-1.63); (2) lack of attention to other people and cars (1.33, 1.12-1.60); (3) improper maneuvering around curves (1.33, 1.09-1.65); and (4) improper or no turn signals (1.33, 1.06-1.69). Information about these driving behaviors should be given to drivers and their stakeholders and used to caution participants when implementing educational programs for older drivers. Self-assessment of driving ability in older drivers provides useful information to raise awareness of their driving performance.
