Driving Status, Habits and Safety of Older Drivers

Objective: To investigate the actual driving status and driving related safety issues of older drivers aged 65 years or older. Method: We conducted a survey on 56 elderly drivers about driving status, driving habits, safe driver self check list, and medical conditions that may affect safe driving. For comparison, 50 younger drivers aged between third and fifth decades were also surveyed. Results: The mean age of total 56 elderly drivers was 69.96 years old. Their mean driving time in life was 23.6 years and the purposes of driving were shopping (23.2%), religion activity (21.4%) and leisure (16.1%). Most vehicles were equipped with automatic transmission (83.9%) and power steering (91.1%) and the most common type of vehicle was a sedan (82.1%). The incidence of their motor vehicle accidents in recent 2 years was 21.4%, which was higher than that of control group (18.0%) without statistical significance. The driving habits questionnaire revealed elderly drivers tend to avoid rush-hour traffic, driving at night, and high-traffic roads in 75.0%, 69.6%, 51.8% of subjects respectively. The result of safe driver self check list showed that mean demerit score of elderly drivers was 4.3, which was higher than that of younger drivers (3.2). Elderly drivers had hypertension (33.9%), diabetes mellitus (17.9%), eye disorders (8.9%), heart disease (8.9%), arthritis (8.9%), stroke (7.1%), and respiratory disease (5.4%). Conclusion: Compared to younger drivers, elderly drivers tend to avoid unsafe driving situations and reported more safety problems in the safe driver self check list. Elderly drivers also had more medical conditions that may affect safe driving, such as eye disorders, cardiovascular, and metabolic diseases.
