In these classes, the restrictor plate is removed from the engine, giving the driver a substantial increase in power over what was available in the Novice Class. Like the novices, the Stock and Honda Classes are divided into Junior and Senior Divisions. Also there are additional Heavy Divisions for drivers over a certain weight. This helps to eliminate the inherent handicap that larger sized drivers have as compared to their lighter competitors. Each of these classes has Light and Heavy Divisions based on driver weight, as with the Stock and Honda Classes described above.
Drivers draw numbers for starting positions in the heat races.
Heat races are typically 8 or 10 laps long. They are also under the watchful eye of three or more judges who make decisions on what will happen after an incident on the track. Quarter Midget drivers who commit infractions of the rules designed to promote safe and fair racing are penalized. These penalties are assessed immediately and would range from restarting the race at the rear of the pack to being disqualified from the event. When a penalty is assessed, the effected driver is given an explanation of why the penalty occurs.
