2015 Tire Rules Update: Driver feedback meeting to be scheduled later this spring to finalize tire rules.

Transponders Mandatory in 2015: My Laps or AMB compatible transponder must be mounted on the backside of the midplate on Late Models, Modifieds, Pro Stocks & Mid Mods.  Hornets are not required to have transponders.

Pro Stocks must weigh 2,800# at race end with driver (Changed from 2,700# on 4/18/2015)

Race Procedures:

1. Cut off time is 45 minutes prior to start time unless there is a line or traffic delay. Any car arriving late will start in the tail of the first available heat.
2. The only way a car will get a heat position number is when the car goes through the pit gate. It is your responsibility to remember your number. Races will be lined up by the draw except during special events
3. No driver changes after heats. Driver may only qualify one car.
4. Cars must be lined up ready to race at the track entrance 5 minutes prior to their race in starting order. It is the drivers’ responsibility to let an official know if you will be driving two or more cars or will be late. If you are late for your race you will start in the tail of that race. If a lap has been completed you will not be allowed to enter that race. If you miss your heat you will start in the tail of the B feature. If you make cutoff but are unable to race a heat or B Feature you may start at the tail of the A feature.
5. Before the start of the heat race, cars must be lined up in order prior to the flag stand ready to race.
6. In the event of a no show cars will slide forward or criss-cross at official’s discretion.
7. All races will have a time limit. On the original start the field will be given 1 minute per lap to complete the race once the green flag is displayed. In the event of multiple or lengthy yellow flags the white flag will be displayed after the time limit has expired. Please keep in mind that we do not wish to eliminate race length but present a more professional show due to car count and the 11:30 p.m. curfew. The officials will do everything they can to finish each race within the time limit.
8. On all starts there will be no free laps. For example: pulling to the top of the track or delaying the start in any way. You will be put to the tail of the field. No brake checks will be tolerated on starts.
9. Features will be lined up using a redraw for the top finishers in each heat.  The number of cars qualifying for the redraw will vary on the number of heats and total cars competing that night.  The redraw will be configured so no more than half the field is redrawn.
10. All drivers must follow all race officials and lap recorders instructions. Failure to follow instructions or line up in a professional manner during yellows or prior to starts will result in the following penalties. First time is a warning, second warning you will be sent to the pits.
11. Green flag. A cone will be placed in Turn 4. On the original DOUBLE file start the front row will approach the cone at a slow/moderate pace and fire at the cone. The Green flag and light will then be displayed. At that time you will be allowed to pass prior to the cone. If you are in the front row and fire prior to the cone the race will be stopped and that car will be put 1 row back. One or both of the front row cars may be penalized. If you jump the start and are not in the front row you will be penalized two (2) positions per car passed. Jumping a start is considered getting out of line or passing a car prior to the Green flag. On SINGLE file restarts the leader will approach the cone at a slow/moderate pace and fire at the cone. You CANNOT pass a car before you pass the cone. If you jump this start you will be penalized two (2) positions per car passed. Races will not be stopped once the Green flag was been displayed other than for an accident or on track incident. Penalties will be assessed if a yellow is displayed prior to race end or at the pay window if race stays green.
12. Yellow flag. The Yellow flag will be displayed only if an incident has occurred on the track or a car has stopped on the race surface. The car or cars determined to have caused the yellow to be displayed will be placed at the tail of field. Any car that spins or stops to avoid the accident will receive their spot back. If you stop your car in the infield and are not in a dangerous spot we will not stop the race. If you are spun into the infield by another car and cannot reenter race safely the yellow will be displayed and the car that spun your car out will go to the tail. If you are the leader of the race and are spun or get collected in an accident, you will get your spot back. You will not get your spot back if you cause the accident. If you cause two Yellow flags in any event you will be sent to the pits and scored in that position. Mutual respect and courtesy should limit Yellow flags.
13. If you spin by yourself and determined to be out of contention in any heat and make no attempt to reenter race under Green safely you will be sent to the pits and scored in that position.
14. Lapped cars will go to tail on a yellow flag and receive their lap back.
15. In the features only. If you get a flat tire you can stop the race. You will receive Two (2) laps to change the tire in the Hot Pits near the scale. If you go in the pits under green we will not throw the yellow flag or allow you back on the track. If for any reason you enter the pits during the race other than to change a tire you will be scored in that position and will not be allowed to reenter race. If a CLS official sends you to the pits for repairs, two laps will be given to make those repairs. You may reenter the race at the tail.
16. If the flagman stops the race for any car due to safety reasons that car will be sent to the tail. Unsafe cars must be fixed quickly or you will be disqualified.
17. All drivers are responsible to know where the scale is and know when to use it. (Top 3 in heats and Top 5 in features.) Any car that finishes in a scalable position and avoids or passes scale road will be disqualified. After the Features the top 5 must present their car in tech area immediately after scaling their car. Failure to present car for inspection will result in disqualification.
18. Cedar Lake Speedway reserves the right to inspect any car at any time. If a car is found to be illegal prior to a race they must correct infraction prior to racing next event. If a car is found to be illegal after a race the driver will be disqualified and will be awarded zero (0) points and zero (0) purse.
