This document reports information on the KPI speeding, which is defined as the percentage of drivers driving within the speed limit. Speed is a risk factor that is indicative for road safety, and the speeding KPI is an indicator for this risk factor. Seventeen Member States provided data on this KPI, and the figure below provides an overview[1]: it concerns passenger cars during weekday/daytime on motorways[2], rural roads, urban roads and expressways. Denmark and the Netherlands[3] are not in the figure as they provided results on different aggregation levels. The indicators average speed and 85th percentile of speed have also been provided by some Member States, and they complement the main KPI, e.g. by telling whether exceedances of the speed limit are mainly small or large. Speed limits per road type differ between Member States, and a higher speed limit on the same road type usually means a higher share of drivers driving within the speed limit, hence for further comparison between Member States a breakdown by speed limit is also considered.
The limited available data on different time periods suggests that driving behaviour in terms of speed may differ between daytime and night-time and between weekdays and weekends, and provision of data for these different time periods by more Member States could share more light on this.

[1]. No information on the traffic conditions in Ireland was available at the time of writing this report, hence their results may deviate methodologically and therefore are marked differently. The results of Sweden are also marked differently as theirs are based on measurements during daytime and night-time and weekdays and weekends combined.
