ABSTRACT:
A system for on-board timing for a vehicle traversing a predetermined course having at least one marker or indicator such as a start/finish line placed on or adjacent the track. A sensor carried on the vehicle senses when the vehicle passes the marker and provides an electrical signal for actuating an on-board timer and display device. A timing circuit is activated as the vehicle passes a predetermined point (marker) the first and subsequent times. The display device displays the time it took to traverse the prior lap while the timing system times and records the time it is taking to traverse the lap being traversed so that this recorded time can be displayed during the following lap. This sequence of operation continues for each of the laps the vehicle traverses.
