In basic terms, a drag race is an acceleration contest from a standing start between two vehicles over measured distance. These contests are started by means of an electronic device commonly called a "Christmas Tree". Upon leaving the starting line, each contestant activates a timer which is, in turn, stopped when the same vehicle reaches the finish line.
The start-to-finish clocking is teh vehicle's E.T. (elapsed time), which serves to measure performance and often serves to determine handicaps during competition.
Who can compete?
Virtually anyone can compete in drag racing. Drivers are required to have a valid FIA International License, and must be capable of the safe operation of the vehicle.
