Vehicle speed compliance statistics

Statistics and data about the vehicle speed compliance on roads in Great Britain.

Vehicle speed compliance statistics

Vehicle speed compliance statistics provides information on the speeds at which drivers choose to travel when free to do so, and their compliance with speed limits. They were published as free flow vehicle speed statistics before 2016.

These statistics on vehicle speeds in free flow conditions are not representative of average speeds across the whole road network. For such average speed statistics, please visit the road congestion and travel time statistics page.

Guidance on current or previous vehicle speed compliance statistics and free flow vehicle speeds are available.

About the vehicle speed compliance data and reports

Vehicle speed compliance statistics were assessed by the UK Statistics Authority and confirmed as National Statistics in February 2013. The publication includes data from the RAC Foundation and National Driver Offender Retraining Scheme which are not National Statistics.

Vehicle speed compliance statistics are produced by monitoring traffic speeds at about 100 sites using automatic traffic counters (ATC), deliberately located where external factors which might restrict driver behaviour are not present. Statistics are presented by different road types and by different vehicle types.
