The role of exposure on differences in driver death rates by gender and age: Results of a quasi-induced method on crash data in Spain.

•Part of the age and gender differences in driver death rates (DDR) depends on the exposure.•However, direct indicators of exposure are not available in many countries.•When using quasi-induced exposure methodology an increased adjusted DDR for older drivers were found.•The increased risk of death for male drivers was reduced when adjusted DDR were used.•Direct traffic indicators of exposure are needed by sub-groups of drivers.
