Variables of gender and age of the driver, type of vehicle, head injury during the accident, getting to the hospital after the accident and location of the accident were investigated. Kaplan-Meier and Cox proportional hazards model were used for data analysis. Results: The variables, head injury during the accident and getting to the hospital after the accident, had a significant effect on risk of death caused by road accidents.
