In the past I have done some of the Timing on the Rookie Course at Bonneville, this is what usually happens; the starter gives me the race vehicle number and asks be to report back to him/her how the rookie pass went; here is what I look for at the 2 mile point of the course where the Timing Tower is located:
#1 did they go between 125 to 150? if so that qualifys for the run;
#2 if their racing class record is over 175 mph they must deploy the parachute for us to look at for its proper operation like did the deployment cause a problem to the car like lifting the rear or front wheels off the ground? then the chute is located wrong on the car,
#3 after going thru the finish line and deploying the chute, did the vehicle clear the course towards the return road so I can call the next car? if numbers 1-3 are accomplished OK, then I call the starter on the FM system and tell him that vehicle qualified for his "D" license, then the vehicle driver goes to the starter and
get his timing slip signed by the starter, so they can get their "D" license, after that they are no longer a rookie and can go to the 3 mile course for more license runs, hope that helps some.
