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.

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.
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.

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.

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.

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

B. Once a driver has refused and/or chose not to use their awarded provisional, they will have forfeited their right to use said provisional for that night and it will be awarded to the next eligible driver with no exceptions.
C. All Teams wanting to take a provisional must have attempted to compete in at least one preliminary event leading up to the Feature.
D. Provisional starters tag the rear of the Feature.
E. If provisionals are permitted in the Feature event; the car(s) owner(s) and driver(s) will earn full WoO points.
F. All 2022 WoO Platinum Member race teams that raced the entire 2021 season either as an Owner or Driver are permitted unlimited provisionals during Volusia Speedway’s February Event. After the Volusia Event, these teams will be awarded 2 provisionals. 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.
G. Any Owner or Driver that has already exhausted their allotted provisionals but gain additional provisionals by switching teams and/or by any other legal means will earn show-up points only for any further provisional starts.
H. Multi-car teams cannot rotate drivers to enhance their provisional position.
I. Any Team using a provisional shall forfeit the minimum start money paid for the Feature. Any position attained that pays greater than the start money will be paid as advertised minus the start money amount.
J. All Teams wanting to take a provisional must have attempted to compete in at least one preliminary event leading up to the Feature.
K. Provisionals tag the rear of the Feature.
L. An unlimited number of WoO awarded provisionals will be permitted for each event’s Feature.
M. The following guidelines will be used for determining provisional order:
a. For the first 5 race nights of the 2022 season provisionals will be awarded and lined up according to last year’s final Owner and Driver Point standings.
b. Beginning on the 6th night of racing, current Owner Points will determine the provisional order.
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.
