Your trap speed is based on how long it takes you to clear both sets of lights, and is therefore your average speed while you traveled from the first set to the second. Technically, it should be a hair lower than your actual speed at the finish line, assuming the car is accelerating the whole time. That said, this is the accepted way to measure trap speed, and people in the know understand that it's not truly your exact speed at the moment you cross the finish line. It's not an estimate, it's an approximation. The difference is subtle.
