Road safety 

Speed enforcement

Driving too fast or inappropriate speed contributes to a third of all collisions.

Thames Valley Police uses modern technology to identify locations where and when speed enforcement is needed. We focus on the blatant offender, roads where excessive speed contributes to injury collisions and locations which are subject to valid complaints.
