(1) No person shall drive any vehicle in any race, speed competition or contest, drag race or acceleration contest, test of physical endurance, exhibition of speed or acceleration, or for the purpose of making a speed record, and no person shall in any manner participate in any race, competition, contest, test or exhibition.

(2) The provisions of this section shall not prohibit the use of the highways for organized motoring activities where speed or acceleration is not the objective of the contest but rather the prime objective is the precise measurement of time and distance within the posted legal speed limits.

(3) The provisions of this section shall not prohibit organized motoring activities upon the highways where speed is a primary objective of the contest when prior written permission is obtained from the authority having jurisdiction over the area to be used, and prior notification is given to law enforcement agencies in the area to be used.
