Section 20.10.I.2: Add the following sentences: “There are three trip beams at the Start line, each approximately 7.75” off of the ground; the Pre-Stage beam, the Stage beam, and the Red Light beam or Guard beam. The Pre-Stage and Stage beams are 7” apart, with the Red Light beam 17” from the Stage light beam. The Pre-Stage light and beam is only advisory to the driver and the light does not need to be on when the tree is activated. The Stage light must be on when the tree is activated and until the green light comes on (see Section 20.10.I.3). If the Red Light (Guard) beam is broken, the Stage light will go off indicating a “deep stage”. If the tree is activated while the Guard beam is broken, the red light will immediately come on and the run will be scored as a DNF.

Section 20.10.I.3: Replace 4th and 5th sentence with the following: “If the car is not staged with the Stage Light on from the time the tree is activated until the green light comes on, the Red Light will illuminate and the run will be scored as a DNF. This includes the car lifting and coming out of the stage light beam upon leaving the line before the green light comes on. If a car is barely breaking the Stage beam, the driver is advised to add a “flapper” to avoid staging problems upon acceleration (See Section 20.10.I.6 & 7). In the case of bye run where only one car is staged, the red light will come on immediately for the side of the tree corresponding to the empty lane when the tree is activated by the starter, while the side of the tree corresponding to the lane with a car will operate in the normal manner.

Section 20.10.I.6: Replaced with the following: “All vehicles may add devices (flappers) to break the stage, start, and finish light beams (trips).
