A device for placement on a toy racing track to count the number of laps traversed by a toy vehicle, comprising a spring loaded lever extending into the path of the vehicle that advances counting wheels which display the count. The deflection of the lever by the toy vehicle winds the spring, and the advance of a counting wheel occurs only on the return of the lever, so that the counting wheels do not receive the shock of a fast vehicle hitting the lever. The lever directly advances both a digit wheel and a 10-counting wheel, the digit wheel having a depression that allows a ratchet on the lever to engage the ten-counting wheel once in each revolution of the digit wheel.
