Time Limits – A 30-minute time limit will be imposed for the A feature, with a 15-minute time limit for all heats and the B feature dependent on the number of cars. When the time limit is nearing expiration or inclement weather dictates otherwise, laps may be cut and the drivers will be advised via the receiver. Track management will determine qualifying and line-up procedures for special events. LICENSE AND MINOR REQUIREMENTS – Persons under 18 years of age are required to have written permission signed by parent or legal guardian before they are allowed in the pit area.

Once all qualifying heat races have been completed, the show is considered to be complete. Any features not yet completed will be made up during a future regularly scheduled program.
If the race program is shortened due to bad weather, refunds will not be given as your ticket will be good for the next regularly scheduled event.
Raceceivers All competitors are required to use a raciever at each event. Drivers must notify a track official preferably Line Up Person if he or she is having problems with their devices prior to the start of their race. If you do not use a raceceiver, you will not race. If found in tech after race to have not had a raceceiver you will be disqualified. (Exception being hearing impaired) Original Starts Original starts will be 2 abreast – side by side. The front row must set an even pace. If the front row cannot set a pace that allows the start of the race, after 2 attempts, they will be placed at the back of the field. Cars must be nose to tail until the green flag is dropped. Your signal that we are ready to start the race is when the flagman turns out the yellow light. Heat Race Restarts Restarts will be single file. The leader of the race will set the pace for the restart. No passing is allowed until you reach the orange cone in turn #4. Any driver that jumps on a restart will be penalized the number of positions jumped and will be so notified over their raceceiver. Should there be a yellow flag prior to the end of the race, the offending driver will be moved back the appropriate number of positions. Once the white flag has been displayed the next flag will end the heat race. Unassisted Yellow Flag – Heat Races If a driver causes an unassisted yellow, your heat race is over and you must exit the track. Feature Restarts After the completion of a lap and either a yellow or red flag is displayed, the race will restart with the leader in front of the field. The remaining field will have a double file realignment with the second-place driver choosing either the inside or outside position (With the exception of RaceSaver Winged Sprint that restart single file). The fourth-place driver will always start inside the third row. Only two double file restarts will be allowed. Once we have had two double file restarts, any additional restarts will be single file. Track management may, at their discretion, choose single file realignments. Once single file restarts are in order, drivers are not allowed to pass until they have reached the Orange Cone in Turn #4. Unassisted Yellow Flag – Feature If a driver causes 2 unassisted yellow flags in the feature, he or she must exit the track. Their race is over. Track Protocol Any car that stops on the track without cause will be placed to the rear of the field. Should your car be disabled, stay in your car (until the race is over) with helmet and seat belts on, unless you are in danger from spilled fuel or other fluids. If you do so, you will be disqualified. If you stop to miss a wreck on the track and regain forward motion before the yellow is displayed, you will get your spot back. If you spin or stop on the track before the yellow is displayed to avoid a wreck and do not make contact, you will get your spot back. If any contact is made, you will be placed at the rear of the field. If driver is driving in a detrimental, dangerous manner a warning will be issued over the raceceiver, if actions and contact continue the black flag will be displayed and you will be asked to leave the track. Any driver who track officials deem to be driving in a manner that is detrimental to other drivers or unsafe will be black flagged and sent to the pits. Track officials reserve the right to relocate any driver to the rear of the field for the safety of all competitors. All race cars must be able to start under their own power (Red flag condition is an exception). Should a push start be required, the driver will be placed at the rear of the field. Any driver that intentionally stops on the track and brings out a caution without the effort to exit track to infield will be disqualified from the race. Working on your car while on the track during a yellow or red flag is not allowed. If the red has been displayed and you have been allowed to exit the track to the hot lane, you are not able to work on your car until the caution light has been turned on.
Powder Puff and Mechanic Races All Powder Puff and Mechanic race entries must not be registered drivers at any track including US 36 Raceway and Bethany Speedway. Powder Puff and Mechanic race drivers can not be entered nor race another division. Lap Count Any cars that pass the start/finish line before a yellow or red flag will be scored the way in which they came across the line. All other cars will be scored by the order in which the crossed the line on the previous completed lap. Races will be considered complete after the leader takes the checkered flag. Should a yellow or red flag occur during the feature before the lead car takes the checkered flag, the race will be realigned and revert back to the running order of the previous lap. The race will finish with 2 more laps (Green, White, Checkered). Hot Lane A designated hot lane will be provided for use during feature events. Drivers will be given two laps after the initial yellow is thrown to return to the track. If your car was deemed to be involved in the yellow incident, you are not guaranteed any laps in the hot lane. Do not try to re-enter the racing surface until a track official has given you permission to do so. Post-Race Tech The top 5 finishers in the feature must proceed to the scales in the infield. Cars not meeting weight requirements will automatically be disqualified with no points or pay being awarded. Drivers will be notified via racecievers as to who needs to proceed to the tech area, also located in the infield. Failure to scale and or go to the tech area will cause an immediate disqualification. The feature winner will proceed to Lake Road Warehouse Victory Lane at US 36 and Pettijohn Winners Circle at Bethany Speedway for the trophy presentation before reporting to the tech area. Pay Pay will be by check available at the West Concession Window at US 36 and Concession Stand at Bethany as soon as race results are finalized. Drivers must start the feature in order to earn feature pay. Drivers or their designee will be required to sign for their pay. Drivers are responsible for collecting their pay. Conduct Fighting in the pits will not be tolerated. Drivers are responsible for your pit crew’s actions. Driver’s, pit crew or family members going to another competitor’s pit without US 36 Track Officials is not allowed. Should a driver want to talk to another competitor, contact Track Officials and they will go with you to that person’s pit area. By not doing so, you will be subject to a fine or suspension. We expect all rivers to respect one another, Track Officials, and most importantly our Fans. We will not tolerate profanity and or obscene gestures directed towards Track Officials, Other Competitors or Fans. If you have any questions contact one of our Track Officials who will relay your question to the appropriate person. We may not be able to provide an immediate answer but will get you an answer as soon as possible. Under no circumstances should the driver or any person affiliated with the car approach the scorer’s booth without prior permission. Track Officials decisions will be final.

LAKESIDE SPEEDWAY - CENTRAL MISSOURI SPEEDWAY - US-36 SPEEDWAY - BETHANY AND GRAIN VALLEY SPPEDWAY 2019-2024 PURE STOCK RULES As of 12-20-2019 The spirit and intent of these rules is to maintain the integrity of “stock” car racing. In recent years, stock car class rules have moved away from the original intent of maintaining a car class that is easy as possible on the common man’s wallet! Help us keep the integrity of the rules by conforming and abiding by the rules in keeping with the intent of maintaining the future of the class! Do not read between the lines, if something is not in this rule book; do not assume you can make things up on your own, ask questions and clarifications if you are unsure of anything. The assigned Technical Inspector has the final say in rules clarification. Although these rules were designed around already existing “like” car classes in the general area, there are differences, read carefully, “I didn’t know” is not an excuse. The track owner has final say on permission to race in this division. Younger or inexperienced drivers may be asked to turn practice laps prior to being allowed onto the race surface for competition. Changes, additions, and edits since the last edition (2018), are annotated in bold red and underlined.
