Grass Hogs Racing - 2017 Rules


**NOTE** THERE ARE NO NEW RULES OR CHANGES FOR 2017

General Rules
The following rules are for all races held by Grass Hogs Racing. They are designed to be as fair as possible for all.
The members of this club have adopted a code of conduct for its members, crew personnel, officials, and any other persons involved with a sanctioned race event.
All of the rules should be read thoroughly as they will be enforced at all events.
Failure to abide by the club rules will result in penalties being imposed on the driver:
Any offense of the rules will result in discretionary action as deemed appropriate by the race officials.


Code of Conduct
1. No drugs or alcohol shall be consumed during any race event.
2. Absolutely NO profanity or insulting behavior will be tolerated at any race events.
3. Each racer is responsible for his or her guests while at each race event.
4. All drivers must register no later than Ĺ hour prior to the drivers meeting.
5. It is the responsibility of each driver to know the flag rules.
6. At no time during a race shall anyone other than the track officials and the participating drivers be on the track, unless a red flag has stopped the race. The exception will be during the juniors' races when support persons will be allowed access to the track.
7. Absolutely NO unsportsmanlike conduct will be tolerated.
8. In the event there is an issue on or off the track involving drivers or pit crew, the people involved shall not confront each other in any way. Any issues shall be brought to the race officials to be dealt with in a civilized and fair manner. Failure to do so will result in immediate removal from the racing area and pit area. The race officials will decide the future of those involved as in penalties or complete banning from racing and the possibility of revoking membership.
9. If approached by a driver or member asking for variances in the rules to accommodate a driver to use a tractor not meant for that class to fill in on race day it is up to the race officials to allow the variances on that day. IT IS BY NO MEANS A RULE CHANGE. In the event that the variance has been agreed upon the driver will be made aware that he or she will not be receiving a trophy or any money available on that race day. Allowing these variances to the rules on race day helps keep our performance level up for the spectators and venues.

Personal Safety Equipment
Personal safety gear as follows:
CSA/DOT approved full face helmet with a shield, visor or goggles in all classes of racing
- Chest protectors are manditory in all classes of racing
- safety neck brace
- gloves
- long pants
- boots which cover the ankles
- a jacket or long sleeved shirt
- attached tethered KILL switch to be used at all times when on the tractor
- ALL safety rules will be strictly enforced for everyone's safety
- No entry to race track without ALL safety gear

Race and Track Rules
- Racing grid will be determined by public draw at the drivers meeting. Qualifying heats will be run to determine your position for the feature race.
The number of heat laps will be 12 laps and the feature race will be 15 laps for all classes except Juniors which well be 5 laps for the heat qualifier and 8 laps for the feature. Any questions on this can be directed to the Track Director at any time.

- You and your tractor MUST run in the Qualifier to make it to the Feature. A MINIMUM of two complete laps must be made in the qualifier to race in the feature race. Drivers who qualify (complete at least 2 laps) but don't finish their qualifying heat will start in the rear of the feature race grid. Any driver not completing 2 full laps in the qualifying race starts at the back of the grid and will not receive any trophy or monies that may be available on race day, unless you have gone off the track due to mechanical failure and verified by a track official. You will then be eligible trophies or money that may be available on race day. A driver must use the same tractor for both the qualifier and the feature race - if you change tractors for the feature race you will not be eligible for any trophies or monies that may be available for that race.
NOTE: you cannot just race two laps then drive off the track; there MUST be a legitimate problem with you or your machine.
- the race track is CLOSED immediately following the feature race. There will be NO extra laps unless the track owner gives permission.
- All starts will be rolling Nascar type.
Starts are controlled by the main flagman. When the green flag drops the race is started, but you must maintain your position until you cross the start line.
- Yellow flag laps do not count.
- Under the yellow flag drivers must stay in single file in their current running position. Main flagman will ensure that drivers are in proper restart position.
- If you cause the yellow flag you must take the rear position.
IF A DRIVER GOES INTO THE INSIDE OR OUTSIDE OF THE TRACK THERE WILL BE A YELLOW FLAG AND THE RACE RESTARTED AS PER YELLOW FLAG RULES
IN THE EVENT OF A YELLOW CAUTION FLAG FOR ANY REASON, ALL DRIVERS INVOLVED WILL BE MOVED TO THE BACK OF THE PACK. DRIVERS ARE RESPONSIBLE TO BE IN CONTROL OF THEIR TRACTORS AT ALL TIMES AND SHOULD BE PREPARED TO TAKE EVASIVE ACTION TO AVOID COLLISION WITH A STOPPED TRACTOR ON THE TRACK, OTHERWISE THEY WILL BE CONSIDERED PART OF THE CAUTION CAUSE AND WILL BE MOVED TO THE BACK OF THE PACK. THE MAIN FLAGMAN IN COLLABORATION WITH THE SCOREKEEPERS WILL ENSURE CORRECT POSITION OF ALL DRIVERS BEFORE THE GREEEN FLAG RESTARTS THE RACE.
- Intentional bumping, uncontrolled ramming of the racer ahead, reckless driving or blocking will not be tolerated, and will result in disqualification. Any intentional infractions will result in being black flagged after one warning.
- Racers being lapped must stay on the outside line of the track.
- Drivers are responsible for knowing their starting positions for the heats and features.
- Drivers must stay near their tractors while in the grid line up. Failure to be present at race grid immediately prior to your race may mean forfeiture of your position and you may not be allowed to participate in that race.
- If a driver leaves the track during racing they must safely reenter as close as possible to where they left the track, and must yield to traffic (you can not gain a position). If a driver does gain a position they will be given one lap to give the position back. Failure to do so will result in being black flagged or no longer scored.
- If a tractor quits running during a race the driverís first responsibility is to move the tractor to a safe distance off the track (to the center or outside the track, whichever is closer). You must remain on your tractor until the race is over, you can not work on your tractor during the race.
- All tractors will be inspected at registration by the tech personnel to ensure the tractor's eligibility in each class. The tech stewards have the right to retech any tractor at any event upon their discretion.

Flag colors and what they mean

Six flags are used to send signals to the drivers during the race. The flag colors are white, yellow, green, red, blue with yellow stripe and black. Flag positioning will have different meanings ie. open flag, rolled flag. Drivers should be familiar with the meaning of the signals used by the flagmen, to ensure safe and fair racing for everyone.
Green flag - Signals the start of the race, or restart of racing after a caution or stop flag.
Crossed green and white flag signals the half way point of the race.
Yellow flag - This is a caution flag. When the yellow flag is out racers are to slow down, continue at a slow speed in single file and do not gain position (do not pass). Racers should watch the flagmen for further instruction.
IF A DRIVER GOES INTO THE INSIDE OR OUTSIDE OF THE TRACK THERE WILL BE A YELLOW FLAG AND THE RACE RESTARTED AS PER YELLOW FLAG RULES

IN THE EVENT OF A YELLOW CAUTION FLAG FOR ANY REASON, ALL DRIVERS INVOLVED WILL BE MOVED TO THE BACK OF THE PACK. DRIVERS ARE RESPONSIBLE TO BE IN CONTROL OF THEIR TRACTORS AT ALL TIMES AND SHOULD BE PREPARED TO TAKE EVASIVE ACTION TO AVOID COLLISION WITH A STOPPED TRACTOR ON THE TRACK, OTHERWISE THEY WILL BE CONSIDERED PART OF THE CAUTION CAUSE AND WILL BE MOVED TO THE BACK OF THE PACK. THE MAIN FLAGMAN IN COLLABORATION WITH THE SCOREKEEPERS WILL ENSURE CORRECT POSITION OF ALL DRIVERS BEFORE THE GREEN FLAG RESTARTS THE RACE.
White flag - This flag signals the start of the last lap.
Checkered flag - Signals the end of the race, and indicates the winner.
Red flag - All drivers are to stop and wait for further instruction.
Blue flag with yellow stripe - This is a flag to indicate to driver to move to the outside of the track so he can be passed by faster traffic.
Black flag - A rolled black flag is a warning to the driver for an infraction of the racing rules. An open black flag signals disqualification and the driver must remove himself from the track immediately.

All decisions are final and at the discretion of the main flagman, the two corner flagman and the score keepers.
