d. The scales used for the event, provided by the series or the track, will be considered the official scales for the event.
e. Scales will be available for any team to verify its car weight as determined by the official scales for that event.
f. The number of cars to be scaled nightly will be announced at the driver’s meeting, on the pit board, and/or instructed via the driver’s one-way radio.
g. At the scales, the car must present themselves directly onto the scales. The figure shown is the official weight for that car.
h. Officials will allow a car to re-scale two times by pulling off the scale and pulling back on. Reading of the final attempt will become the entered weight.
i. If, at the scales, the car fails to meet the minimum weight, the following penalties apply:

i. Qualifying: The car forfeits the earned qualifying and must start last in a heat race.
ii. Heat Race: The car is penalized for that event but remains eligible for the next qualifying race.
iii. Preliminary Mains, LCS, and Feature: Car and Driver will be scored in the last finishing position of the race.

E. Restrictions

a. Once a racecar has been started or once any race has been started, all work on the racecar must be completed in the designated work area unless informed otherwise. Any participants who do not work on the car in the designated work area are subject to disqualification and/or fine and/or suspension and/or any other action deemed appropriate by Officials and/or World Racing Group Supervisory Officials.
b. On the initial push, during a yellow and/or red flag situation if a car needs more than one (1) ‘push-off’, except for safety reasons, that car will be penalized 2 running positions.  A ‘push off’ is considered completed only when the pushed vehicle has started and pulled away from the push vehicle.
c. Drivers and/or team members will not be permitted to tamper with track racing surface.  Any participants who tamper with the track racing surface are subject to disqualification and/or fine and/or suspension and/or any other action deemed appropriate by World Racing Group Supervisory Officials.
d. Any driver, crew member, or team associate that enters the racing surface without express approval from an official are subject to disqualification and/or fine and/or suspension and/or any other action deemed appropriate by World Racing Group Supervisory Officials.
e. All drivers should not exit their car unless there are extenuating emergency circumstances.  They should shut off the electrical power, remain in their car, and wait for track and/or safety officials without removing any personal safety equipment.  At no time should a driver and/or crew member approach any portion of the racing surface or another moving vehicle.
f. If a car/driver switch is made, for any reason, that car/driver must start at the rear of the next segment of the racing program in which that car/driver has qualified for.

F. Entry and Pill Draw

a. All drivers and/or teams entered, in any event, must draw for a position in qualifying order at the designated location. The drivers and/or teams are responsible for their own pill draw.  Only one (1) car may be entered per driver in any event.
b. All pills will be drawn prior to the driver’s meeting. If a driver and/or team entered and present at the event does not draw, that team will be placed at the end of the qualifying order. In the event that there is no qualifying, then the driver and/or team will start at the rear of their specified qualifying race.
c. All participants shall be DIRTcar Members in good standing to participate in any event draw.

G. Hot Laps

a. All entered cars will hot lap by the qualifying order.  If a driver misses their respective group, they will forfeit their opportunity to hot lap.
b. The AMB Scoring Transponder must be mounted on the racecar prior to hot laps.
c. If and when track packing is required any car that does not participate will be given only one (1) qualifying lap and/or the best the car may qualify is 50% + 1 of the entered cars for that event.

H. Qualifying

a. Qualifying will consist of two consecutive timed laps unless otherwise noted. Changes to the two-lap qualifying procedure will be at the discretion of series Officials.
b. When conditions and circumstances allow multi-car qualifying may be utilized at the sole discretion of WoO Officials.
c. Qualifying may be split into two or more separate qualifying groups based on car count.  Regardless of the situation, a car must qualify within its overall assigned group.
d. Qualifying will take place in the order of the pill draw. Each car and/or team will have a two-car and/or two-group grace period to be in line for their own qualifying opportunity.
e. If the grace period is missed the late car will take its qualifying at the end of the scheduled lineup and receive only one qualifying lap. The best a late car can qualify is 50% (lower number) + 1 of the overall number of qualifiers in a group no matter what the qualifying time of record is posted.
f. Once a car is pushed and/or rolls for time trials, even if it doesn’t start, that is considered an attempt to qualify.  If the car leaves the track and goes to the pit area or returns to the qualifying line it will be considered late and will only receive one qualifying lap as outlined above.
g. The cars that are late must be in line before the last scheduled car attempts to qualify.  Qualifying will be closed once all cars that are in line have attempted to qualify.
h. In the event of two or more cars posting the same qualifying times, the tiebreaker will be the fastest other lap time of the two consecutive recorded laps. If this does not break the tie, the tie will be broken by the qualifying pill draw. In the event that one (1) lap qualifying is utilized, the tiebreaker will be the qualifying pill draw.
i. In the event of inclement weather and/or unforeseen circumstances, it is at the discretion of the World Racing Group Supervisory Officials to revise the qualifying procedure.

d. Any driver transferring from the heat race(s) to the feature race that does not qualify for the redraw will line up for the feature race based upon the driver’s finish in the heat race.
e. Any driver that does not transfer from the heat race(s) to the feature race will be assigned to compete in an LCS and/or preliminary main.

J. Last Chance Showdown(s)

a. The Last Chance Showdown(s) lineup will be determined by the finishing order of the heat race(s).
b. The number of laps and number of transfer position(s) from the Last Chance Showdown will be based on the overall car count for the event and announced at the driver’s meeting.

K. Backup Cars

a. A backup car may be introduced at any time between qualifying and the start of the Feature due to the original car not operating properly and/or from extensive damage.  Such determination will be at the sole discretion of the Series Officials. Any such change will result in the driver starting at the rear of the next race segment for which the driver has qualified for. If a driver changes car(s) after hot laps, that driver will remain in his drawn position for qualifying and will be positioned in subsequent races accordingly.
b. If a backup car is introduced, the car must pass pre-race technical inspection prior to any competition. A backup car may be obtained from any source and does not have to be part of a team’s original equipment.
c. An additional entry/inspection fee may be due for the introduction of any backup car where applicable.

b. Any driver, team, and/or car, who purposely attempts to hold up the start of any race will be placed at the rear of the lineup and could be disqualified from the event, suspended, and/or fined at the discretion of the World Racing Group Officials.
c. Once the allotted time (announced at the driver’s meeting) allowed for being on the track or in the push-off and/or staging area, ready to race, has expired, any late car will be penalized to the rear of the field.  Sprint Car push off will be two (2) positions.
d. Any car pushed or joining the field after the field has started assembling must start at the rear of the field.
e. In any race once the one (1) to go signal has been displayed cars will not be allowed to enter the racing surface unless directed by a Series Official.
f. All starts and restarts will take place at a consistent speed. Consistent speed will be at the discretion of World Racing Group Officials. Starts will take place within a designated area that will be identified at the driver’s meeting. Any car out of line and/or passing before this point will bring out a caution period and will be penalized two (2) positions on the ensuing restart. If an offending car is located on the last row of the starting grid then that car is allowed to restart but will be penalized 2 positions from its finishing position. If the same car commits a second offense it shall be disqualified from that event. All front row cars must choose their racing line coming out of turn three (3) and must maintain that line until the start or restart occurs. Failure to do so will result in a two (2) position penalty.  Failure to acknowledge and comply with the “move back” signal may result in being parked for that race.
g. In the event that the race is not properly started by the two (2) front row cars, the responsible car(s) may be moved to the second row. Failure to acknowledge and comply with the “move back” signal may result in being parked for that race.
h. Alternate starters for any race will not be permitted to start any race after the original start has taken place.
i. One (1) complete lap must be completed before the race is restarted using a restart lineup.
j. The pole car sets the pace and the front row starts the race together at the designated area, regardless of a displayed flag. Any passing before the front row accelerates will not be permitted.
k. If a caution comes out on the original start or before one (1) lap is completed, the car or cars that brought out the caution will lineup at the rear of the field and the race will have a complete restart for the remainder of the field with cars lined up by position at the discretion of the race director.

N. Restarts

a. All restarts will take place with the lead lap cars moved to the front of the field. Lapped cars will pull to the inside and fall in behind the last car on the lead lap in their order of running.
b. If a car is unable to properly restart the race after the one (1) attempt, the car will be penalized two (2) positions.
c. When an infraction occurs on a restart, World of Outlaws Officials may exercise their discretion and allow the race to continue, not calling for another restart, and then penalize the offending car(s) under yellow flag conditions or at the conclusion of the race. The offending car(s) will be penalized two (2) positions plus any positions gained.
d. The restart area will be at the designated restart area, which will be announced at the Driver’s Meeting.

f. Any cars that stop in the pit/designated work area, during a caution period will be required to restart from the rear of the field.
g. Any cars that are involved in a red flag situation will be required to restart at the rear of the field, including cars that go to the pits during a red flag situation.
h. Under red flag conditions any car that stops because of a blocked track, at the discretion of the Series Officials, will not be considered involved in the red.
i. Any car that is stopped for consultation during a caution period will retain its position only if the Series Officials deem the car ‘clear’ and permit it to return directly to competition without adjustment.
j. If a car is not in a proper nose-to-tail alignment and/or is laying back to create an excessive gap between cars, then that car may be penalized. If there are multiple violations, the car may be disqualified from the event.
k. Double-File Restarts: Under yellow-flag conditions, the field initially goes to a single-file grid. Once the running order has been established and the field is set the race leader will choose either the inside or outside lane.   The field will then be signaled to realign double-file.  All cars positioned to line up behind the leader will go to the lane the leader has chosen and those positioned to line up behind the 2nd place car will go to the 2nd place car’s lane.  The grid must remain double-file and nose-to-tail until the race is started in the designated start area.  The race leader sets the pace and is the control car. The race leader restarts the race.  Once the leader starts the race it is started for the entire field.  Passing and maneuvering throughout the field is allowed as soon as the race has started.  World of Outlaw Sprint Car Series and/or World Racing Group Officials reserve the right to change and/or alter this rule, provided the competitors are given notice (in advance and/or over the one-way radio) due to any circumstances that require such a change and/or alteration.
l. Restarts will follow single-file procedures (i.e.: cone on front stretch) following a caution period and/or red flag period during the final ten (10) laps of any racing event over 20 laps and single file during the final five (5) laps of any racing event under 20-laps.
m. Single-File Restarts: A restart cone will be placed on the front straightaway.  Cars will assemble in a single file running order.
n. All cars must pass to the right of the restart cone(s) in a single file, nose-to-tail manner.
o. If a car passes to the left of the restart cone, hits the cone, passes another car before reaching the cone, is not in a proper nose-to-tail alignment, and/or laying back to create an excessive gap between cars, then that car will be penalized two positions. Any car in the last 2 running positions of the restart that commits an offense will be allowed to restart but will be penalized 2 finishing positions. If there are multiple violations, the car may be disqualified from the event.

O. Racing

a. Any car that does not race on the designated racing surface in order to better its position will be black flagged and penalized at the discretion of the Series Officials.
b. The maximum number of event laps will be stated by the Series Race Director during the driver’s meeting but may change due to extenuating circumstances.
c. Any car that spins, is involved in an incident, and/or has a problem but does not bring out the yellow flag and/or create a caution period, will blend back into the field where the driver is able to do so. If there is an inadvertent caution period, the Series Officials will determine the placement of the car(s) involved. The placement of the car will be where the car blended back into the field.
d. At the discretion of the Series Official, any car that is involved in two (2) or more unaided spins may be penalized.
e. All races must be completed in a “green-white-checker” finish. This means if the yellow flag is displayed or caution lights illuminated prior to the leader receiving the checkered flag, that race will be restarted and run for two consecutive laps before completion. Under certain conditions, at the discretion of Series Officials, a one-lap “white – checkered” finish is allowable.
f. If a race is red-flagged due to weather conditions and cars are sent to the pits, then any and all work, including tire changes, is permitted.
g. If there is an incident resulting in a closed red situation and the determination is made to go to an open red then all the cars that were considered involved, whether they went to the work area or not, will re-align at the rear of the field in their scored position on their last completed lap. Order is lead lap cars, 1 lap down cars, and multiple lap down cars
h. A spin or stoppage that requires a car to be restarted during a yellow flag slow down period is considered as being involved and will result in said car or cars re-aligning at the rear of the field along with other cars that were involved in the yellow stoppage.
i. If it is determined in any race, after the original start, that any competitor deliberately initiates a caution period, by any means, that competitor may be penalized.  The determination of what constitutes deliberately initiating a caution period will be at the judgment of the and/or World Racing Group Officials.
j. Any cars going to the work area and re-entering the race together will be positioned in the order of their last scored lap at the rear of the field behind cars that are on the same lap as they are.  If a restart green flag is displayed and followed by a yellow or red flag before a lap is scored, then any car(s) that remained in the work area can re-enter the race but will be positioned behind any same lap car that took the aforementioned restart green flag.  If a car remains in the work area it can re-enter during any ensuing race stoppage, lining up behind any cars that are on the same lap as said car that is re-entering.
k. Officials may complete an event, at any completed lap count, at their discretion, if a condition or circumstances create a reasonable inability to continue. The race will be considered complete unless announced otherwise.
l. If, when officials determine in their sole discretion that unforeseen circumstances prevent the completion of the advertised distance or make it impractical to continue or complete the race within a reasonable time after it has been stopped, the race will be considered officially completed as of the last lap scored by the leader prior to the race halt. The finishing positions will be determined, as they would have held if the race had been restarted.
m. A pace car may be utilized to pace the field prior to the start of the event and on all restarts. Passing of the pace car, unless otherwise instructed to do so by the Series Race Director will not be permitted.
n. Hand signals, colored gloves and colored sticks will be permitted during the use of communication with drivers. Flashlights, anything with electricity and/or two-way radio communication or any electronic communication with drivers will not be permitted.
o. Any driver not qualified for the Feature that gains entry into the Feature due to a car/driver separation will earn show-up points only for the entire event.
p. In the event that a race car is inadvertently or purposely hit by a push truck, pace vehicle or purposely hit by another race car during push-off, or under yellow flag conditions or other non-racing activity and such incident is witnessed by a World of Outlaws Official, then repairs can be made to the contacted vehicle and that car will resume it’s running position. The maximum time period allotted for such repairs is six (6) minutes.  If repairs cannot be completed within this time period, then the car will be scored as finishing last in that race. Alternate(s) starters will not be given a starting position in this situation. In the event the damaged car is not able to reenter the race, the car will be scored last on the lap in which that car has completed.
q. When a car is presented in the designated lineup area or during push-off for any event competition, any tire change is prohibited.  Any tire change will result in forfeiting starting position. Penalty will be starting in the last position.
r. Adding fuel, whether on the track or in the work area, will not be permitted when yellow flag and/or closed red flag conditions exist.

P. Work Area

a. When the yellow flag is displayed a two (2) minute period will be permitted for the repairs of any race damage.  The time will begin once the car has reached the designated work area.  The car will rejoin the field at the tail of the lap it’s on once the work has been completed at the direction of Series Officials.  After the completion of halfway of the race, the two-minute period will no longer be in effect.

Q. Flag Rules and Officials Signals

c. Red Flag

i. All red flags are considered closed red flags unless Series Officials determines it needs to be an open red. In an open red flag, a work area may be designated on the racing surface. All cars will be moved to the designated work area on the racing surface before work begins.
ii. When the red flag is displayed all cars on the racing surface and in the pit areas must come to a complete stop in a controlled manner, while not stopping and/or driving through the area of the incident.  Cars are not permitted to move for any reason unless instructed by Series Officials.  Any car that moves during the red flag without permission will be penalized and/or parked.
iii. During any red flag situation all drivers, unless involved in the incident must remain in their car unless otherwise instructed by Series Officials.
iv. During any red flag, once the field is stopped, the race director may offer the opportunity for any car to the work area by signaling to do so with instruction over the one-way radio. Any car that goes to the work area for service during the red flag period will surrender its running position and have to restart at the rear of the field and/or if the race is canceled due to inclement weather, the car will be scored behind those cars which did not go to the work area.
v. If the race is red-flagged due to inclement weather conditions, work and tire changes will be permitted.
vi. CLOSED RED:  The track will be closed. Crew members will not be permitted on the race track and/or to their race cars.
vii. OPEN RED:  The Race Director will determine when the track is open. Any repairs and/or adjustments, except changing a tire or wheel, can be made to the race car.  When the Race Director determines that the racing may resume; an air horn designating the start of a 2-minute work period will be sounded.  At one-minute remaining, the air horn will be sounded twice.  At the end of the 2-minute period, the horn will be sounded, officially ending the work period.  Crews must be clear of their car when the 2-minute period has expired or be penalized 2 running positions. Last row cars violating this procedure will be penalized 2 positions from their finishing position.  Any car still being worked on once the field has started assembling will be disqualified and not allowed to re-enter the race.
viii. FUEL RED: As soon as all the crews have reached their cars an air horn designating a 2-minute work period will be sounded.  The 2-minute work period procedure is the same as outlined above. Any repairs and adjustments, except changing a tire or wheel, can be made to the race car as long as they are completed before the 2-minute period has expired.

d. Black Flag

i. If the black flag is displayed, then the driver that the flag is being displayed toward must bring their car to designated pit work area immediately for consultation. The car will not be scored from the point that the black flag has been displayed. If after the car is inspected and it is able to return to competition, the car may only return to the track during a caution and/or red flag period.

e. White Flag

i. When the white flag is displayed this signifies that the leader of the race and/or the car that is qualifying has started the last lap of that event.

f. Checkered Flag

i. The checkered flag signifies the completion of the event. All cars must pass underneath the checkered flag to be scored correctly on the final lap of the event.
ii. Once the leader has crossed under the checkered flag, that race will be considered complete.

g. Officials Signals

b. All cars must have and/or provide adequate hardware for the attachment of the Scoring Transponder.
c. All cars are required to be equipped with a scoring transponder securely mounted on the specified location. It is the competitor’s responsibility to ensure proper installation and working condition of the scoring transponder.
d. If a car is found to have a non-functioning scoring transponder, they will be directed to the pits to have one installed.  A penalty may be assessed at the discretion of series officials.

Section 2 – Scoring Procedures

A. All races are scored at the designated start/finish line.
B. A lap will not be scored on the original start and/or any restart unless all cars complete the lap by passing through the start/finish line except for the cars involved in the incident.
C. After the first completed green flag lap, following the original start or restart, when the caution is displayed all cars that were scored under green flag conditions will hold that scored position with all other cars lining up according to their last completed green flag scored lap. This partial lap will count toward the event’s total number of laps. Racing back to the start/finish line will not be permitted.  This is also known as split scoring.  A completed lap is considered leader plus one (1).

Section 3 – Payoff Procedure

A. All paid purses, appearance money and/or other awards and/or funds as outlined in the promoter’s contract shall be paid to the car owner and/or designated owner’s representative.

Section 4 – Provisional and Alternate Starting Positions

On July 1, 2022, any Platinum Team in good standing will earn an additional 2 provisionals. 2022 Gold Members will start the season with 2 provisionals but do not receive unlimited provisionals at Volusia. Gold Members in good standing will transition to Platinum status after the 5th night of racing.  The total provisionals any team can accumulate for the 2022 season is four (4). However, unlimited provisionals will again be awarded to all Platinum Teams that are in good standing during the World Final’s event at Charlotte Motor Speedway.

c. When using 2021 Owner and Driver Points for the first 5 nights of racing, the provisional order will be established by combining the two-point lists into one, numerically sequenced, list. If a team consists of a 2021 Owner and a different 2021 Driver, then that team uses whichever has the highest point position. Owner Points will take precedent if a tie exists between any Owner and Driver. Other ties will be broken first by 2021 A-Main Feature wins, then top 5 finishes, then top 10 finishes, and finally by qualifying position.

N. Tracks, where a weekly sprint car program is raced and pointed, may install a program identically paid and pointed as the WoO provisional program, for up to 2 local drivers.
O. In the event a qualified car/driver for the Feature Event is unable to take the initial green flag, the qualified car/driver will receive feature points and purse for last place. Any reason for not being able to take the initial green must be approved by Series Officials. In the event that multiple cars/drivers cannot make the initial green, they will be scored and pointed at the back of the field based on starting position. Alternates will no longer be taken to the Feature Event.
P. If at any time during the racing season a Platinum Team splits and both the Owner and Driver retain their Platinum status then both the Owner and Driver will be eligible for any unused Provisionals the Team had when the split occurred.

Section 5 – Racing Program and Special Show Events

A. There may be special event shows during the year that do not follow the Series racing formats. When such events occur, all teams will be informed of specific program and/or procedural changes for that particular event. All racing programs are subject to change and any such changes will be explained to all competitors prior to the race.
B. From time-to-time mandatory appearances, interviews and or/autograph sessions will be scheduled. Drivers will be notified of attendance and location at selected events. If any driver fails to report to any autograph session a written penalty may be issued, which could result in loss of points, starting positions earned and/or fine(s).
