A friend recently asked me what a speed trap is, in terms of F1. The speed trap is the fastest point on the racing circuit. It is generally towards the end of the longest straight, and just before the braking point of the corner. The speed trap is used to obtain and compare the fastest speeds amongst drivers.

This snippet from formula1.com shows the speed trap of the Valencia circuit (the yellow spot) – it’s located at the end of the longest straight section of the track.
