3 1. GENERAL 1.1. DISCLAIMERS No person attending a TCRC club event will have any claim for damages, expenses, lawsuits, or otherwise against a promoter, track operator, the TCRC, its officials, agents, or employees, resulting from any damage to any car, personal injury, or monetary loss of any kind whatsoever All attendants waive any claim they may have against a promoter, track operator, or the TCRC, when they participate in any event being run under this set of rules By entering or attending a TCRC event you agree to these disclaimers wholly and by your own accord. In addition, you agree to the rules set forth herein and the penalties associated with infractions of said rules COMPETITION From time to time questions arise and need to be answered. To help cure the possible confusion over whom to ask what question, the following break-down has been provided: For clarification or inquires about an TCRC event (race day schedule, frequency changes, etc.), questions should be directed in this order: (1st) Race Director (2nd) Appointed Host Official For clarification or inquires about technical inspection at an event, questions should be directed in this order: (1st) Appointed Technical Director/Inspector (2nd) TCRC Director (3rd) Appointed Host Official For clarification or inquires about the TCRC (series points, upcoming TCRC events, etc.), questions should be directed in this order: (1st) TCRC Director (2nd) TCRC Webmaster The event host or race director has the right to refuse any entry upon a valid reason If the refused entry is a competitor that has scored TCRC points during the current series year, the Host must communicate with the TCRC Director prior to refusing entry All drivers are responsible for the actions of their pit crew and/or accompanying party All drivers and/or pit crew are required to wear closed toe shoes at all times while on the track or in the pit lane area Substitute drivers will not have those runs counted towards overall finish or series points for the person being substituted for Any driver that does not have complete control over his vehicle must immediately pull his car off the racing surface.

4 A driver s official time will be the total laps completed by his vehicle and the total time elapsed from the starting time until the vehicle crosses the finish line on the final lap. If the final lap is not completed, the driver will be credited with the number of full laps finished and the time for those laps If a car is broken then fixed, it must be restarted from pit lane (restarting from pit lane applies to both Electric and Gas classes) CLASSES The following classes will be awarded TCRC Championship Points and will be offered at all TCRC events: SPEC Slash RTR Brushed/17.5 Short Course X4 Short Course Open 2WD Short Course /10th 2WD Open Truck /10th 4wd Open Buggy /10th 2wd Open Buggy /8th Truck (Both Nitro and Electric) /8th Buggy (Both Nitro and Electric) Additional, non-series classes may be offered. 3 vehicles constitute a class REGISTRATION & ENTRIES The Northwest RC Speedway and Tri-Cities RC club races are open to all competitors unless previously banned from any race, competition, event or facility; no special membership is required unless specifically stated on an event flyer In the instance of previous banning; the competitor must file petition (providing all related information on said expulsion) with the TCRC Director The TCRC Director will contact all of the current years TCRC Operators/Directors for a decision on allowing said driver into series competition Entry fees may be waived for those approved by the TCRC Series Directors/Track Operators/RD In the event that a class is not run at the first 6 TCRC events, due to a lack of entries, that particular class will be dropped from the series driver s championship for the remainder of the year. The class may still run just not within the championship point s race In the event that a class is not run at 5 TCRC events, series awards will not be issued A minimum of 3 drivers starting an A-Main constitutes a class Entry limits (class size limits or number of non-series classes offered) will only be implemented if time constraints are of concern.

5 1.5. PRACTICE Practice is open to the general public without fee during considerate operating times unless full scoring system is running and available at which time operators may charge a fee not exceeding $5 per person It is highly recommended that this practice day end no later than 10pm QUALIFYING Qualifying for an TCRC event shall be a minimum of 2 rounds (weather permitting) and shall be scheduled to finish by 6:00pm on Saturday and Sunday Races and by 11:00pm on evening starts The format shall be 6min IFMAR Qualifiers utilizing the Rocket Round system (Most laps completed in fastest time) for Electric classes and 7min IFMAR Qualifiers utilizing the live loop method and based on Rocket Round system (Most laps completed in fastest time) for classes running Nitro vehicles No Resort is required but may be desired if multiple heats of a class are present After the resort the slowest qualifier rounds (per class) will run first, progressing through the class finishing up with the fastest (per class) qualifying rounds last While the order in which classes are ran is up to that specific race RD to decide, it is highly recommended that Electric and Nitro classes be intermingled during qualifying so that the Electric class entrants have sufficient preparation time between heats/rounds The tie breaker for qualifying shall be the awarded to the driver whom has the most laps in the least amount of time in the unused qualifying rounds MAINS All Mains for a TCRC event shall be held on the day in which it started (unless with special request), scheduled to finish within reasonable time The format of the Mains shall be: ELECTRIC CLASSES: All classes to get Single Mains of 8min (Exception the SPEC Class will stay 6 min) 2 bump-ups per Lower Main GAS CLASSES: 15-Min A-Mains 7-Min Lower Mains 2-Bump ups per Lower Main All competitors must start their main event with the car they qualified with It is illegal to change cars/trucks during a heat or main event The tie breaker for Multiple Mains (If Run) shall be awarded to the driver whom has the highest combined laps with the lowest combined time in the 2 rounds that were scored SHORTENING OF MAINS

6 Gas mains shall not be shortened unless the following has occurred: 1) No cars are on the track. 2) With the time remaining in the race no positions can change. 3) In the event the timing and scoring computer fails at any point beyond the halfway point of a 15 or 8 min main, all positions at the time of failure shall be used as the final results for that main event TIMING AND SCORING FAILURE In the event the timing and scoring computer fails before the halfway point of a 15 or 8 min Main, the main will be restarted with half of the mains original length to be run; regardless of the point at which the failure occurred Cars running or fueling in the pits at the time of the failure will be allowed to start the restart Any broken vehicles at the time of failure may be allowed to run the restart per director but shall start in the back of the grid A False Start called within the first 2 laps of a main is NOT a Timing and Scoring Failure If timing and scoring transponder fails during a heat or main event neither the Race Director nor the TCRC are responsible for lost or missed laps or the resulting position at which said driver will be credited with. Best efforts may be made to adjust for proper laps however The use of personal transponders are highly recommended, but not required. Use of personal transponders will greatly increase the reliability of counting drivers laps. Rentals are available during the day of the race and require a form of collateral RAIN-OUTS In the event of a rain out of: 1) The entire event: TCRC will reschedule the event at a later date with the host. 2) All of Mains: Qualifying shall be used to determine finishing positions and series points. 3) All of qualifying: The most current TCRC series standings shall be used to determine grid positions for the mains. 4) 2 rounds of Qualifying: 1 round of Qualifying shall be used to determine grid positions TURN MARSHALING It is required that all entrants turn marshal (or provide a replacement turn marshal) in the heat directly after: Their assigned controlled practice heat (whether they have driven or not) Their assigned qualifying heat (whether they have driven or not) Their assigned race heat (whether they have driven or not) Failure to turn marshal as specified by rule may result in penalties to be assessed by the officials listed. However due to the small nature of most club events it is per the TCRC director discretion whether it is feasible for the participant to Marshal.

7 Turn Marshals should not work on cars while marshaling and rather be focused on their duties as a marshal Turn Marshals shall be actual entrants of the event whenever feasible. The Operator/RD shall determine if substitutes who are not event entrants are deemed acceptable TECHNICAL INSPECTION FOR CLASSES REQUIRING INSPECTION (SLASH) At the earliest possible time prior to a TCRC event or during the drivers meeting prior to the start of qualifying the Appointed Tech Inspector shall be identified The Appointed Tech Inspector shall oversee the tech inspection process and may appoint associates to help in the tech inspection process Any appointed associates will have shown sufficient aptitude in understanding the tech inspection process The Appointed Tech Inspector shall instruct/train the associates on correct tech inspection processes The Appointed Technical Inspector may inspect any car, at any time for compliance with event and/or TCRC regulations All vehicles are required to pass requirements listed with these rules. While most likely not all rules will be inspected, it could happen and all entrants should be prepared for such a complete inspection It is highly recommended all cars pass through Technical Inspection at some point during the practice day Any questions with regard to Technical Inspection policies, practices or to the legality of a specific component are to be asked prior to the beginning of qualifying After the first qualifying heat for a particular class begins all cars within that class are subject to the technical rules and penalties set forth herein Failing technical inspection: 1st Offense: Warning 2nd Offense: Disqualification from the round, forfeiture of all points earned at that round for all classes entered In lieu of fuel capacity technical inspection for all Gas Class competitors, the drivers competing in the A and B Gas Mains will be required to make the following number of pit stops: Class A-Main (15min) 1/10th Gas Truck 1 1/8th Buggy (Nitro/Electric) 1 1/8th Truck (Nitro/Electric) 1 Monster Truck (Nitro/Electric) 1 A pit stop shall be defined as: 1.

The car must receive fuel, batteries, repairs, or brief inspection.

8 4. The car must be returned to the surface of pit lane. 5. The car must exit pit lane. Hopping the divider (pipe) entering or exiting pit lane during a pit stop will NOT be considered a pit stop and the stop will NOT count toward the required number of stops. A stop and go penalty is NOT considered a pit stop and does NOT count toward the required number of pit stops. A 2-lap penalty may be administered per pit stop missed PENALTIES The penalties listed through-out these rules are to be used as a reference. Depending on the severity of the infraction or the level of blatant disregard for a rule, the penalty applied shall be consistent with the circumstances The Race Director and the Appointed Host Official will have the authority to penalize, disqualify or eject any driver from their event for the violation of these rules The TCRC Director will have the authority to penalize or disqualify any driver from receiving series points for an event The following actions by a driver or his pit crew could result in disqualification and/or ejection from an event and/or the TCRC: Assaulting (verbally or physically) another individual Unruly or unsportsmanlike behavior Showing evidence of being under the influence of alcohol while the race program is running The use of illegal substances, showing evidence of being under the influence of illegal substances and/or being in possession of illegal substances on the facility premises Not reporting to the inspection area when requested Not providing equipment for technical inspection when requested Operating a car near the track that endangers others, or while a race is going on Turning on a radio during a race with the purpose of interfering with another drivers race Failing technical inspection and/or refusing repairs Any driver ejected from an event will not be refunded event entry fees for any reason The following actions by a driver could result in a time penalty or loss of a heat: Ignoring a penalty given by the Race Director Rough driving or hacking Failing to corner marshal on time.

9 Allowing individuals to substitute for you in a race (no penalty but no points awarded for that heat) Using a non-assigned radio frequency Failing to attend the morning drivers meeting A race official must witness the infraction before a penalty can be assessed.
