The Bullring at Las Vegas Motor Speedway
2011 Official Rules and Regulations

These rules are in effect as of January 1, 2011.  This publication supersedes all previous LVMS rule books and rules updates.
LVMS reserves the right to alter or amend these rules and regulations in the interest of safety, cost control, and/or fair competition.  It is the responsibility of each competitor to read and understand the contents of this rule book. If there is a disagreement or dispute regarding the meaning or application of these rules, the decision of the Bullring’s Chief Technical Inspector shall prevail.
The rules and regulations set forth herein are designed to provide for orderly conduct of racing events and to establish minimum requirements for such events.  These rules shall govern the conditions of LVMS short track events, and by participating in these events, all participants, guests, race members and staff are deemed to have complied with these rules and/or regulations. No express or implied warranty of safety shall result from publication of, or compliance with these rules and regulations.  They are intended as a guide for the conduct of the sport and are in no way a guarantee against injury or death to participants, spectators or others.  In the event of a serious or fatal injury, LVMS reserves the right to impound race cars for review and evaluation, and may exercise this right at anytime.  The Chief Technical Inspector shall be empowered to permit minor deviations from any of the specifications herein or impose any further restrictions that, in his opinion, do not alter the minimum acceptable requirements.
No pretense is made for having designed a foolproof set of rules and regulations.  The spirit and intent of the rules is the standard by which LVMS short track events will be governed. LVMS tech officials are authorized to decide if an equipment change or modification is an attempt to circumvent these rules.  LVMS officials can and will disqualify a race car in violation of the spirit and intent of these rules. 
Note: If this rule book does not specifically state that you can alter, change, or otherwise modify something on your car, you should consider it a violation of these rules.  Illegal components may be confiscated and become the property of LVMS.  No part is deemed to have been approved by LVMS by passing through prior technical inspections.
All participants, guest and crew members fully understand that racing is inherently dangerous and that they are exposed to risks of death or serious bodily injury.  The participants, guest and crew members voluntarily assume these risks.

SECTION 1 – GENERAL RACE PROCEDURE RULES

The following are the track’s procedures for all 2011 events, unless otherwise specified at the drivers’ meeting.  Any questions about these procedures should be voiced at the drivers’ meeting.  All on-track or race procedure disputes, protests and concerns must be addressed with the race director for his final decision within 20 minutes of the conclusion of the final race of the night.

1-1.1  CHECK-IN – All participants must present their tech card and race car(s) to a technical inspector or a technical official before the drivers’ meeting on race night, and before car is allowed to practice.  All drivers must check in prior to the posted deadline on race day.  Any driver not checking prior to the posted deadline will automatically start at the rear of the heat races or, for classes that qualify, receive the second-fastest lap time as his official qualifying time.

1-2.1  DRIVERS’ MEETINGS – All participants must attend the drivers’ meeting.  LVMS reserves the right to penalize any driver not in attendance at the meeting by placing him at the rear of the field for the heat race or feature event.  Spotters should also attend each driver’s meeting.

1-3.1  TECH INSPECTION PROCEDURES – All cars are required to pass a pre-race technical inspection before being allowed onto the track. Failure to do so will result in a $100.00 fine. Drivers must bring their cars through the tech line (including back-up cars).  If a driver has any questions concerns pertaining to the legality of his car(s), it is his responsibility to speak with the Chief Technical Inspector.  Post-race inspection procedures are explained at each driver’s meeting.

1-4.1  QUALIFYING AND HEAT RACES – Drivers may not attempt to qualify more than one car during qualifying or heat races.  All car changes must be reported to the Chief Pit Steward prior to the line-up of qualifying, heat races or the feature event.  A driver may enter the feature event at the rear of the field in an approved back-up or borrowed car if he fails to qualify through time trials or heat races (provided there are less than 26 cars already qualified for the feature event).  If  a car is damaged during the first feature event on a night of twin features, the driver of that car is guaranteed a starting position in the next feature event of that night in an approved back-up or borrowed car.

1-5.1 PRE-RACE LINE UP – All cars must line up in the designated staging area prior to their
respective qualifying session, heat races and feature events.  Any car not staged and ready to go when the race is called to the track will not retain the start position, and will start in the rear, in that race.  The Race Director may allow that car to enter a subsequent heat race or feature event at the rear of the field.  Driver and car are considered one for the entire night, unless the Chief Pit Steward is notified of a change.  In the event that a car drops out of the line-up before a race begins, the cars in the line behind that car will be moved straight forward. A car must take the green flag to receive last-place points.  

1-6.1 INITIAL RACE STARTS – The Chief Starter starts each race.  All initial race starts take place
on the front stretch when the green flag is displayed.  All initial starts will be double-file, nose-to-tail starts at the speed of the pace car.  When the green flag is displayed, cars may not pass the car in front of them until crossing the start-finish line.  Any car passing prior to the start-finish line will be penalized to last place on the lead lap at the next caution period or the end of the race, whichever comes first.  In the event that a start is waived off, the yellow flag will be displayed as the cars enter the backstretch.  Any car deemed to be intentionally slowing the field on a start – or moving out of line prior to the green flag – will be sent to the rear of the field at the Race Director’s discretion.  Any car not taking the initial green flag will not be allowed to enter the race.

1-7.1  RESTARTS – The lead car restarts each race. It is the lead car’s responsibility to accelerate at any point between the two stripes painted on the track in Turns 3 and 4.  If the lead car elects not to accelerate between these two stripes, the Chief Starter will display the green flag and racing may begin.  Cars may not pass the car in front and/or to the left, prior to the start-finish line.  A car is deemed to be “in the act of passing” if its front bumper is even with – or in front of – the rear bumper of the car in front of it at the start-finish line.  On restarts only: a car may pass to the right prior to the start-finish line after the green flag is displayed.  Any car deemed to be “in the act of passing” to the left, or passing to the right prior to the display of the green flag will be penalized to last place on the lead lap at the next caution period or the end of the race, whichever comes first.  All restarts will be single-file in a nose-to-tail formation, maintaining the speed of the pace car, until the green flag is displayed.  Any car deemed to be intentionally slowing the field on a start or moving out of line prior to the green flag will be sent to the rear of the field at the Race Director’s discretion.  Drivers choosing not to go to their designated positions at an official’s request may be sent to the rear of the field or to the pits at the Race Director’s discretion. 

1-8.1  PACE CAR – When the pace car’s lights are extinguished, the race will be “going green” the next time past the designated starting spot.  It is each driver’s responsibility to be ready to start at this time.  All starts and restarts must be at the speed of the pace car.  The leaders must maintain this speed throughout the entire start or restart.  Failure to maintain the proper speed will result in the lead car being sent to the rear of the field.  Any car called to track exit for consultation with an official may be permitted to pass the pace car during caution periods.

1-9.1  JUMPING ON STARTS AND RESTARTS – Any driver who begins racing, passing or is not in a nose-to-tail formation before the green flag is displayed will be penalized for jumping.  Any car not in the nose-to-tail formation is subject to penalty for jumping.  Any driver considered jumping will be penalized to last place on the lead lap at the next caution period or at the end of the race, whichever comes first, on the first jump-start.  If a driver is caught jumping a second time in the same event, he will be relegated to the pits.

1-10.0 CAUTIONS – At the Race Director’s discretion, the caution flag may be displayed at any time during the race, including on the white-flag lap.  The Race Director may decide to conclude a race while under caution due to time – or time limits – allowed for an event.  The Race Director may also reduce the posted number of laps due to time limits – or a division not being able to run consecutive laps without cautions periods.

1-10.1 ACCIDENT RULES –  When a race is slowed or halted, any and all cars which necessitated the race to be slowed or halted shall be placed to the rear of the field in the order which they com¬pleted the last complete lap. But, a car that is initially involved in an accident and continues through the accident scene under its own power could, at the discretion of the Race Director can return to its position just prior to the accident. The Race Director will make this decision, based on his view of the incident. Stopping to avoid an accident does not constitute causing a caution.

1-11.1 TWO-CAUTION RULE – Any driver causing two caution periods in one event – for any reason – will be black-flagged from the event and relegated to the pits.  Cars stopping to avoid an accident are not required to leave the track after two cautions.  The Race Director will make the final determination regarding this rule.

1-12.1 SPIN-OUTS – Drivers that spin out must make an attempt to continue immediately and not stop the race.  The Race Director reserves the right to penalize any driver one (1) lap for intentionally causing a caution.

1-13.1 ROUGH DRIVING – Any driver who is observed causing other drivers to spin or lose control of their car during a race – or during the “cool-down lap” – may be warned, fined, disqualified and/or suspended indefinitely at the track management’s discretion.  This rule also applies to lapped cars choosing to re-enter the event.  It is important for every driver to respect the equipment of his fellow competitors.

1-14.1  PASSING – It is the responsibility of both the overtaking and overtaken drivers to assure safe passing at racing speeds.  A driver being overtaken must give the overtaking driver a lane to race in. A car is ruled to have lost a position when the overtaking car’s hood pins are even with the driver’s side door of the car being passed.

1-15.1  BLACK FLAG – A black flag will be given to any driver that is losing a part on their race car, smoking, leaking badly, or to assess a penalty.  Lost parts include front or rear bumpers, hoods, body panels, etc. When a black flag is displayed, that driver should immediately report to the hot-pit lane for consultation.  Decisions on black flags will be made by the Race Director.

1-16.1  PITTING DURING A RACE – Any driver going to the pits under during a caution period may return to the race at the rear of the field.  The hot-pit lane may only be used for the removal of loose body parts or other minor repairs.

1-17.1  WORKING ON CARS – All work on the race car must be done in the pit area or any area, which is designated by the officials at the driver's meeting.  No crew members are permitted on the race track at any time except if requested to be there by an official.  Cars in the designated pit area may not be worked on during red-flag conditions.

1-18.1  LAPPED CARS – All lapped cars must move to the outside groove to permit faster cars to pass.  On restarts, lapped cars should remain in their position unless they choose to go to the rear of the field.  Drivers choosing to go to the rear will remain lapped.  If a driver is shown the "move over" flag (blue with yellow diagonal stripe) for two (2) consecutive laps and does not move out of the racing groove to allow faster cars to pass, the black flag will be displayed to that driver.

1-19.1  CARS MOVING THROUGH THE PITS – Cars moving through the pits must do so with extreme caution and at a maximum speed of 5 mph.  Any driver who is observed driving dangerously or at an excessive rate of speed will be fined a minimum of $100 for the first infraction.  No one (except the driver) is allowed to ride in or on the race car at any time.  Failure to obey these rules may result in disqualification from the entire race night.

1-20.1  DRIVER SAFETY – Drivers may not get out of their cars while the car is on the track – except in an emergency such as a fire, fuel leak or severe accident.  Drivers will comply with the directions of safety personnel.

1-21.1  DRIVER AND CREW BEHAVIOR – Any driver or crew member causing a disturbance at the flag stand or on the track with any official will be suspended for a minimum of one (1) week.

1-22.1  DRAIN PLUGS – Please check all drain plugs and gas caps before every race to minimize caution periods due to leakage.  Any competitor “oiling down” the track due to a missing drain plug is subject to a $250 fine and disqualification for the night.

1-23.1  Any situation or incident not covered by these rules will be dealt with at the discretion of the race officials.

SECTION 2 – LINE-UP PROCEDURES

2-1.1 LINE-UP PROCEDURES – All event schedules, qualifying procedures and line-up orders will be released prior to the start of the season.  These may be modified as necessary for special events or circumstances. A copy of the event schedule and line-up procedure will be posted at the credentials building and pit sign-in area.

SECTION 3 – SCORING PROCEDURES

3-1.1 SCORING LAPS – Every lap is scored when the leader has passes the start-finish line under green-flag conditions. Yellow-flag laps may be counted as described in rule 3-4.1.  If the field completes the first lap under green, the first lap shall be scored and any subsequent yellow flags shall result in the drivers lining up single-file in their designated position, based on the last scored green-flag lap. Any racer unable to complete a green flag lap without two (2) cautions will be started single file. Drivers are guaranteed a “green-white-checkered” finish for all restarts within three (3) laps of the finish. After the initial “green-white-checkered” attempt to complete a race, it is the Race Director’s decision to complete (direct the Starter to wave the checkered flag) the race under caution.  If during a “green-white-checkered” finish the caution is displayed with the checkered flag, the drivers involved in causing the caution period will be scored at the rear. The finish will be the last complete lap, with those who were involved in the caution being scored at the rear of the last complete lap.

3-2.1  PASSING UNDER CAUTION – Any driver attempting to improve his position while the race is under caution will be warned and returned to his correct position.  Failure to do so may result in disqualification from the event.

3-3.1  RESTART LINE-UPS – All restart lineups will be derived from the Chief Scorer’s lap sheets, or computer transponder sheet, as the field crossed the start-finish line on the last completed green-flag lap.
Double file re-starts:

All restarts for Bombers, Chargers, Legends, Thunder Cars and Super Late Models are double file.  Once the caution flag is waived the field will remain single file until the caution lights go out and the 1 lap to go is given by the flagmen. When the leader gets to the start/finish, line with the caution lights out, they will remain in the front row all by themselves. Once second place reaches the start/finish line they will remain in the inside in the second row, the vehicle in the third position will go to the outside of the second place car. The vehicle in the forth position will then fall in behind the second place vehicle which would put them in the inside of the third row, fifth place would fall in behind the third place vehicle which would be the outside of the third row. And the same for every vehicle farther back in the field. Drivers will only have half of a lap to get into position as the green flag is being waived the next time by the start/finish line.  Any violation of this rule will result in penalties at the next caution or end of the race, whichever comes first.  Once the pace car has left the field, the leader must maintain pace car speed until the leader is in the vicinity of the white line in turn 4 where the green flag will be waived. At this point you may pass - all passing must be to the right until you have passed the start/finish line. Drivers may only pass prior to the start/finish line in an attempt to avoid colliding with a disabled car (car ahead loses power, misses a shift, etc.).  Any car jumping the start will be penalized a minimum of two places per position gained at the discretion of the Race Director. Any driver who pulls out of line to the left, or passes to the left, before crossing the start /finish line will be penalized a minimum of two positions for jumping the start. In either instance, the driver's position will be corrected at the next caution or at the end of the race, whichever comes first.  Drivers involved in the incident that caused the caution will line up at the tail of the line up for the restart.  Restarts within the final five laps of the event will be single file, with lapped cars going to the tail of the field.

This rule will be reviewed after the third race of the season and is subject to change at the discretion of LVMS officials.


3-4.1  COUNTING CAUTION-FLAG LAPS: Caution-flag laps are not counted in events that are 75 laps in length or less. However, time limits are in effect for all races.  Rules and procedures for extended distance races will be posted at racer registration and covered in driver meeting.

3-5.2 LAPPED CARS –  Lapped cars must go to the rear of the field for restarts when there are less
than five (5) laps remaining in an event.

SECTION 4 – TECHNICAL INSPECTIONS AND PROTESTS

4-1.1  TECHNICAL INSPECTIONS – All cars, car parts, components and equipment are subject to inspection at any time. All decisions regarding the timing and manner of inspection as well as which cars, car parts, components or equipment will be inspected are final. Only one (1) crew member may accompany the driver into the tech area, unless the Chief Technical Inspector requests more crew members.

4-1.2  Only those persons approved by track officials will be admitted into the inspection area.

4-1.3  Track officials will determine whether a car, including any parts, components or equipment meets the specifications for an event as set forth in this rule book.  Only the cars, parts, components and equipment determined to meet the specifications are eligible to compete.  Such determinations may be made at any time before, during or after an event.

4-1.4  A competitor must take whatever steps are requested, including tear-down of car, to facilitate inspection of the car.  This obligation includes, but is not limited to, installing inspection holes, inspection ports and/or any other means of inspection in the roll cage bars, engine components, etc.

4-1.5  If a track official determines prior to the race that the car, including any part, component or equipment, does not meet the specifications, the car will not be permitted to compete unless the deficiency: (a) will not adversely affect the orderly conduct of the race; (b) cannot be corrected in time for qualifying or the race; (c) will not provide the competitor with a significant competitive advantage; and (d) is so insubstantial as not to warrant a determination that the car is ineligible to race.  If the track official permits the car to compete under these circumstances, the track official will apprise the competitor of the deficiency, and if the deficiency has not been corrected by the next race, a penalty may be imposed and the car will not be permitted to compete until the deficiency has been corrected.

4-1.6 NASCAR and the track officials have the right, for inspection purposes, to seal or impound cars, parts, components or equipment entered and competed in an event.  NASCAR, track officials or the promoter are not responsible for payment, reimbursement, damage or loss to the competitor as a result of such sealing or impounding.

4-1.7 Any car that has competed in the event may be inspected at the conclusion of the event.  NASCAR and/or track officials have the right to confiscate any part, component, equipment and/or fuel – without obligation for payment or reimbursement – which fails to meet the specifications of the NASCAR or LVMS rule book.  If track officials determine that any part, component, equipment of fuel used by a competitor does not meet specifications, track officials may declare the car ineligible for the event, resulting in loss of points and/or prize money.

4-1.8 Track officials have the right to confiscate any part, component, equipment and/or fuel – without obligation for payment or reimbursement – which fails to meet the specifications of the NASCAR or LVMS rule book. 

4-1.9 Inspection and/or eligibility decisions are final.  All decisions made by LVMS officials will be final – and are not appealable – at the conclusion of the racing event.  LVMS officials have the right to postpone a ruling to have an independent third party test the equipment in question.  LVMS officials will notify the competitor at the event if such action is taken.  Any competitor that refused tech inspection after competing will forfeit points and prize monies for that event. Second refusal during the same season will result in loss of all track points earned to that date, and loss of points and purse monies for that event. The competitor or one team representative has the right to be present during inspections.

4-2.1 PROTESTS:  If a NASCAR member who is a driver believes that another driver has obtained a significant unfair competitive advantage by some action that the member believes is in violation of NASCAR or LVMS rules, the member may protest such action.  The protest must be made in writing by the competitor (may be made by his crew chief if the driver is on the race track) within 20 minutes after the checkered flag is displayed.  Each separate protest shall be accompanied by a $200.00 protest fee; however, a separate protest that involves the removal of the crankshaft from the engine shall be accompanied by a $750.00 protest fee.  Also, a separate protest that involves the removal of a piston and/or connecting rod for the engine shall be accompanied by a $500.00 protest fee.  Track officials will decide whether the manner is eligible for protest, and if so shall decide the protest as promptly as possible, and shall inform the parties to the protest of the decision.  If a protest is accepted and deemed to be a valid protest, LVMS will retain $100.00 for an administrative fee.  If the protested vehicle is found to be legal, then the protest fee – less $100.00 – will be given to the protested vehicle.  If the protested vehicle is found to be illegal, the person filing the protest will retain his protest money, minus $100.00.  A track official may decline a protest – even if the matter is eligible for protest – if he determines that the alleged rule violation is so insubstantial as to not provide the competitor with a significant competitive advantage.  The decision that the matter is not protest able is final and not eligible for appeal.  In deciding the matter, track officials may take whatever action is appropriate to further the interests of fairness and finality in competition results.  Such action includes – but is not limited to – revising the official race results, imposing penalties (disqualification, suspension or fines, and/or loss of finishing positions in the event), awarding or subtracting points or taking no action.

4-2.2 Protests will not be accepted on any subject not specifically provided for in these rules.  Such
subjects include –  but are not limited to – timing-and-scoring decisions, inspection decisions and race procedure decisions.

4-2.3  LVMS officials have the right to deduct points and/or disqualify competitors that violate these rules.

SECTION 5 – IDENTIFICATION
