The first three races are not timed. These races eliminate the slowest cars. Races will be timed starting with the fourth race. One team member must wait at the finish line to catch the car. Cars stalled on the track will be retrieved at the conclusion of the race.
Judges have the option to inspect any car at anytime during or after heats.
Challenges must be made before the next round begins. All challenges must come from the participants who are actively involved in the heat. Participation ribbons will be given to all participants. Trophies may be given to the participants involved in the final race. The intent of the solar car project is for the kids to have fun.
