Current risk and exposure estimation is an important phase of the road safety assessment. These two factors are closely related – in order to estimate the risk, it is necessary to know a particular exposure measure. In addition to the population and the number of registered vehicles, one of the main exposure measures, which are used when estimating the risk, is the mileage driven. In relation to the first two exposure measures, the mileage stands out primarily because of low measurability and data unavailability, i.e. the lack of some efficient data collection methodology. In addition to the methodology, i.e. the way to collect exposure data – mileage driven by passenger cars in this case – this paper presents the correlation between mileage driven and passenger car age. Also, the paper presents descriptive statistics on the mileage driven by passenger cars. Mileage data for this study was collecting from April to May 2019. The sample was collected based on the data obtained from vehicle inspection companies. The results of this paper indicate that the drivers of older vehicles are less exposed than drivers of newer vehicles.
