OECD study says inappropriate speed responsible for up to 30% of all fatal crashes

Inappropriate speed is responsible for 20 to 30% of all fatal road crashes according to the latest review of research on the relationship between speed and crash risk.

A new report by the OECD’s International Transport Forum analysed eleven cases from ten countries that have recently changed speed limits or introduced large-scale automatic speed control i.e. using time-over-distance cameras. The analysis confirmed the very strong relationship between speed and crash risk and that higher speed is associated with increased occurrence and severity of road crashes.

The study also echoes ETSC’s view that the default speed limit where motorised vehicles and vulnerable road users share the same space, such as in residential areas, should be 30 km/h.
