RACE RULES
-All drivers must draw a pill before Hot Laps. Anybody who has not drawn a pill before hot laps will be put on the tail of the heat or qualifying.
-Bombers and Mod Lites will use pill draw for heat race lineup.
-When qualifying starts, you must be in the staging lane when the car before you pull on the track or you will lose your qualifying attempt. You will then have to start the tail end of a heat.
-Heat races will be listed on the pit board at pit building after qualifying. Drivers will be expected to be lined up and ready when it is time for your heat.
-Double-file starts will begin at cone or chalk line coming off turn four at the signal of the green flag. Pole Sitter will set pace speed.
-No passing or getting out of line before passing the cone or chalk line.
-Single-file restarts will start at cone on the backstretch.
-No passing or jumping the start before the cone. First offense you will be warned. Second offense you will be sent to the tail. Third offense you will be disqualified and sent to the pits.
-Line up reverts back to the running order of the previous lap. Drivers will be expected to fall in line where you belong. The track officials will make the necessary adjustments. Do not jump out of line after a track official has placed you. You will be warned on the first offense, if you still do not line up in the correct position, you will not be scored.
-The two-caution rule will apply to all drivers. If you cause two cautions, you will be black-flagged and sent to the pits. Also any car deemed unsafe or too slow will also be black-flagged.
-Rough driving will not be tolerated. Drivers are aware of what "rough driving" is, and so are we. You will be called for it, so don't do it.
-We will be using the judgment rule, so if you need to stop to avoid an accident, you won't be sent to the tail. If you spin someone, you will go to the tail. If two cars are both at fault for causing the caution then both cars will be charged and go to the tail.
-No drivers are allowed to pass below the racing surface. Violations can result in being sent to the tail and disqualification.
-No Radios.
-Once you leave the track you are done, so do not try to come back on the track.
-No crewmembers will be allowed on the track, flag stand, or press box to argue an official's call. Violators can face suspensions.
-No Fighting . Fighting by drivers and/or pit crew members can result in lengthy suspensions.
-Any driver who holds up show by not leaving track after being black flagged can face suspension.
-If a driver is DQ'd for a serious violation such as holding up the show and not leaving the track when told, using their car as a weapon, or endangering a track official, that driver will receive no pay or points and will be scored last. This DOES NOT include a situation where a car is DQ'd for being too slow, causing two cautions, etc. This will only include serious and dangerous situations. In the tracks five year history, a situation like this has only happened three or four times so we are not expecting a situation like this to occur.
-When a driver is shown the layover flag, you must KEEP YOUR LINE when faster cars approach. If a driver refuses to yeild to the layover flag and keep their line, they will be black flagged and sent off the track. This is a safety issue as we do not want cars wallering all over the track while faster cars are trying to pass.

RACE RULES
-All drivers must draw a pill before Hot Laps. Anybody who has not drawn a pill before hot laps will be put on the tail of the heat or qualifying.
-Bombers and Mod Lites will use pill draw for heat race lineup.
-When qualifying starts, you must be in the staging lane when the car before you pull on the track or you will lose your qualifying attempt. You will then have to start the tail end of a heat.
-Heat races will be listed on the pit board at pit building after qualifying. Drivers will be expected to be lined up and ready when it is time for your heat.
-Double-file starts will begin at cone or chalk line coming off turn four at the signal of the green flag. Pole Sitter will set pace speed.
-No passing or getting out of line before passing the cone or chalk line.
-Single-file restarts will start at cone on the backstretch.
-No passing or jumping the start before the cone. First offense you will be warned. Second offense you will be sent to the tail. Third offense you will be disqualified and sent to the pits.
-Line up reverts back to the running order of the previous lap. Drivers will be expected to fall in line where you belong. The track officials will make the necessary adjustments. Do not jump out of line after a track official has placed you. You will be warned on the first offense, if you still do not line up in the correct position, you will not be scored.
-The two-caution rule will apply to all drivers. If you cause two cautions, you will be black-flagged and sent to the pits. Also any car deemed unsafe or too slow will also be black-flagged.
-Rough driving will not be tolerated. Drivers are aware of what "rough driving" is, and so are we. You will be called for it, so don't do it.
-We will be using the judgment rule, so if you need to stop to avoid an accident, you won't be sent to the tail. If you spin someone, you will go to the tail. If two cars are both at fault for causing the caution then both cars will be charged and go to the tail.
-No drivers are allowed to pass below the racing surface. Violations can result in being sent to the tail and disqualification.
-No Radios.
-Once you leave the track you are done, so do not try to come back on the track.
-No crewmembers will be allowed on the track, flag stand, or press box to argue an official's call. Violators can face suspensions.
-No Fighting . Fighting by drivers and/or pit crew members can result in lengthy suspensions.
-Any driver who holds up show by not leaving track after being black flagged can face suspension.
-If a driver is DQ'd for a serious violation such as holding up the show and not leaving the track when told, using their car as a weapon, or endangering a track official, that driver will receive no pay or points and will be scored last. This DOES NOT include a situation where a car is DQ'd for being too slow, causing two cautions, etc. This will only include serious and dangerous situations. In the tracks five year history, a situation like this has only happened three or four times so we are not expecting a situation like this to occur.
-When a driver is shown the layover flag, you must KEEP YOUR LINE when faster cars approach. If a driver refuses to yeild to the layover flag and keep their line, they will be black flagged and sent off the track. This is a safety issue as we do not want cars wallering all over the track while faster cars are trying to pass.
