RACE PROCEDURES
- The
only people allowed on the racetrack and outside the infield pit
guardrail are racing officials. Drivers must stay in their cars while
on racetrack. DO NOT GET OUT OF YOUR CAR. Pit crews, car owners and
personnel related to any car are not allowed on the track following any
accident or injury.
- No
repairs are allowed to a racecar except in the pit area. Pit crews are
not allowed to come on to the racing surface for any reason during an
event. This includes red flag situations.
- Drivers
may compete in only one division per race night (this does not include
the Showdown in Savannah). Late Model drivers are allowed to compete in
other divisions only on weekly race nights that the Late Model division
is not competing (must be approved by the chief steward).
- A
driver may move up a divisio*Rule Amendmentn during the season, but once they have
made the move, the driver cannot move back to that division without a
majority vote by that division’s drivers (must be approved by the chief
steward).
- Drivers
must draw their own number for heat and qualifying line-ups at the draw
window prior to entering the night’s event. Heat and feature line-ups
will be posted in the pits (at the pit concessions).
If a driver wins two (2) feature events in a row, they cannot start any
farther forward than the 8th starting position of the next feature they
qualify for; three (3) feature events in a row, they cannot start any
farther forward than the 10th starting position of the next feature
they qualify for; four (4) features in row, no closer than 12th; five
(5) or more features, the tail of the starting field.
- Any
car that has been qualified for the feature event can be driven by
another driver in that event, subject to notification to scoring, but
will relinquish their starting position and start at the rear of the
field. The same is true in the case of a driver using a back-up car.
The points will follow the driver of the racecar, not the car itself or
the car owner.
- A
back-up car may only be used in the event that a racecar becomes
disabled during preliminary competition (warm-ups or Heat Race) on that
specific race night. If the back-up car does not meet the divisional
specifications, the driver may only complete one lap and exit into the
pit area (no exceptions).
- Cars
must be lined up and ready to race prior to the white flag being
displayed in the previous race. Any driver failing to be lined up prior
to this time will be lined up at the rear of the field. Drivers in
place will move straight up in their rows with the latecomers falling
to the rear in the order they came to the staging area. All drivers
must follow the official’s direction.
- The
race begins at commencement of pace laps, but official scoring and
distance begins when the official starting flag is displayed. At the
beginning of the race, the field must maintain a nose to tail, side by
side formation at a consistent speed until the green flag is waved. If
a caution is displayed prior to a lap being completed, a complete
restart will result with all retaining their starting positions except
for those determined to be involved in the cause of the caution. If
after three unsuccessful tries at starting a race double file fails, a
single file start will be used.
- When
a caution flag is thrown, drivers must slow down safely and maintain
their position on the track. We do not race back to the flag stand. If
a full lap is not completed, we will go back to the last completed lap.
- At
the discretion of the officials, any car causing a caution or any car
involved in causing the caution will be placed at the rear of the field
for the resta*Rule Amendmentrt. Any driver involved with three (3) cautions within the
same race, will be black flagged from that race and sent to the pit
area.
- All
restarts are double file and made by the lead car anytime after passing
the designated line on the wall and prior to flag stand. If the leader
does not fire by the time he reaches the flag stand, the flagman will
restart the race. All drivers must remain in position and are not
allowed to pass until after the restart. When the leader accelerates,
the remainder of the field must do so also. If you do not accelerate
when the remainder of the field does and you are passed, this is not
considered a jump. Jumping is a judgment call that is determined by
track officials. The first time a driver is deemed to have jumped the
restart, they will be penalized two positions from where they were
before they jumped the restart at the next available time or at the end
of the race, whichever comes first. A second jump within the same race
will result in a black flag and a one-lap penalty. If a car breaks on a
restart, they should move to the inside or outside to allow remainder
of field to pass.
- If
a red flag is displayed, slow down as quickly as possible and come to a
stop on the track. We may need to dispatch the ambulance and fire truck
and they need a clear path to the accident.
- There
will be NO ROUGH DRIVING. Any car that intentionally spins out or
drives into another car will be immediately black-flagged to the pits
for consultation with the officials, and will be subject to further
penalty as deemed necessary. We will not tolerate rough driving.
- All cars must enter the speedway in turn one and exit the speedway in turn four.
- Drivers
must maintain a safe speed in the pit area (even if during a race). Any
driver entering or exiting the pit area at what is deemed to be an
unsafe manner may be black-flagged from the race and be subject to
further penalty.
- During
the regular season on regular race nights (does not include double
feature nights or nights when heats are not run), the following
distances and time limits will be imposed, unless changes are necessary
and are made by chief steward prior to the event:
| Division
Heat Laps | Feature Laps | Time Limit |
|---|
| LM | 5* | 25* | 25 minutes |
|---|
| *Rule AmendmentSS | 5 | 20 | 25 minutes |
|---|
| MS | 4 | 15 | 20 minutes |
|---|
| PS | 4 | 15 | 20 minutes |
|---|
| 440 | 4 | 15 | 20 minutes |
|---|
*The number of heat and feature laps will be determined by the car
count at that event. A time limit of seven (7) minutes will be imposed
upon each heat race. The time begins when the initial green flag falls.
When the time limit has been exceeded, the race will be declared
official when the leader is given the checkered flag. Rookies must
begin their heat and feature race from the rear of the field for their
first three events (double features are considered two events).
18. If the time limit is reached prior to the completion of the
scheduled laps, a green-white-checkered format will be
implemented immediately. There will be one chance given to
complete the race event under this format. If a caution is
thrown after the
green-white-checkered format has begun, the cars will be scored as they
cross the line and the race
will be considered complete. 19.
Line-ups will be determined by:a. Heat
Races by a blind draw conducted at the draw window. Those failing to
draw prior to draw being cut-off will be placed at the rear of a heat
race. Transfer positions will be dependant upon car count. Divisions
having less than twelve (12) cars will run one (1) heat race.
b. If
a “B” Feature is run, the non-qualifiers will be lined up according to
their finish in the heat races straight up. Transfer positions will be
dependant upon car count.
c. The
“A” Feature for the Late Model, Street Stock, Pure Stock, and Mini
Stocks will be lined up according to their finish in the heat races
straight up. The 440’s will be lined up according to their finish in
the heat races with all previous feature winners in the rear with the
most recent winner at the tail.
d. On
nights when a division does not run heat races, the line-ups will be

20.
On
nights when a division runs double features, there will not be any heat
races run for that division. The line-ups will
be according to the blind draw held at the draw window. The
feature will be inverted from the starting field line up for
the second feature (If you started on the
pole for the first feature, you will start last for the second
feature). 21.
After
any race has been completed, the officials have the right to inspect
any part of any cars. If you are directed to go
to the scales or the inspection area, you must do so immediately.
Any competitor not going directly to the tech area
will be disqualified from the race. 22.
Only
the following persons will be allowed in the tech area unless asked by
an official: OSP officials, OSP management
and two (2) members of the racing team being inspected who are handling
the removal of the requested components to
be inspected. After the components have been removed, only OSP
officials, OSP management, one (1) representatives
of the racing team will be allowed into the inspection
room or area to determine the legality of the components. 23.
All
drivers (including those not directly involved with the inspection) are
reminded they are responsible for their crew
and fans at all times. Misconduct or behavior that is
detrimental to the inspection
process may result in fines and/or
suspensions levied against those teams disrupting the procedure.
This includes activity outside the tech area. Respect
the task at hand.
24. Any participant who refuses to allow tech officials to inspect
their car will be subject to the following: Any competitor
who fails to tear down a car for inspection and/or
fails to surrender any illegal part(s) and/or equipment when
requested to do so by an official will be disqualified from the
event, lose all points and prize money from that event,
be suspended for the next two (2)
events and forfeit 50% of all accumulated championship points. There
cannot be an appeal allowed without the
parts in question turned in at the time the official’s request is made.
The car will remain ineligible
until after the required inspection has been completed by an official. 25.
Any
participant found to be illegal will not
receive prize moneyand may not receive points for that event.
If found
illegal on a double features night, the car will be
declared illegal for both races and will not receive prize money
and may not receive
points for either race. 26.
Confiscation
rules will be in effect at all Oglethorpe Speedway Park events for all
competing divisions. Any team
refusing to relinquish a confiscated part will be
immediately suspended from all speedway operations for a period set
forth by the speedway
officials and management and is subject to further penalties that may
include loss of accrued
points and/or fines. PROTESTS
- If
an Oglethorpe Speedway Park driver with a current OSP license believes
that another competitor has or will obtain a significant unfair
advantage by some action that the driver believes is in violation of
this rulebook, the driver may protest such action to an Oglethorpe
Speedway Park official. All protests must be presented by the driver to
an OSP official in writing; the driver must be competing at the event
and must follow the guidelines of this rulebook.
- A
“visual protest” must be declared in writing to an official at least
fifteen (15) minutes prior to the start of the feature race for that
division and be accompanied by a cash bond of $25. A “visual protest”
is a protest, which does not require any type of measuring device to
determine the legality of any part on the car. “Visual” refers to
anything outwardly visible, and “visual” therefore means anything under
the hood or car that is outwardly visible to the official.
a.
If a “visual protest” is upheld, the driver must turn over the
protested part to the officials prior to the
beginning of the feature. The driver will be fined
$100, which is payable that night or the driver will lose all
points and
prize money for that event.
3. A “formal protest” must be declared in writing to an official
within ten (10) minutes after the conclusion of the feature
race for that division (the second feature in the case of
double feature events). The “formal protest” must include the
proper cash bond at the time the protest is
presented to the official. A “formal protest” can be lodged against
another competitor’s car for an alleged
violation of rules, which is only accessible through the use of tools. a. A
driver must finish in the top ten of their division’s feature race; on
the lead lap and within three places of the car they wish to protest.
There is no protesting of cars finishing worst than you in that feature
event. If needed, official scoring will announce each driver’s
position.
b. The
Oglethorpe Speedway Park official shall decide whether the matter is
protestable and if so, shall decide the protest as promptly as
possible. A decision that the matter is not protestable is final and
non-appealable. The officials have the right to not accept a protest
that they feel has been made in retaliation and/or spite.
c.
Any competitor who fails to tear down a car for after being
protested and/or fails to surrender any illegal part(s) and/or
equipment when requested to do so by an official will be disqualified
from the event, lose all points and prize money from that event, be
suspended for the next two (2)
events and forfeit 50% of all accumulated championship points. There
cannot be an appeal allowed without the parts in question turned in at
the time the official’s request is made. The car will remain ineligible
until after an official has completed the requested inspection.
d. A maximum of one (1) item allowed per protest. Bore/Stroke is considered one item.
e. If
the protest is upheld, the protested driver forfeits all points/purse
won at that event and the cash bond less the inspection fee, is
refunded.
f. If the protest is disallowed, the cash bond will be forfeited to the driver of the protested car less the inspection fee.
g. All
tech items cannot be covered in this book. If while in the process of
inspection or engine tear-down, officials see another non-protested
tech item which is viewed to be an intentional violation of the
rulebook, then tear-down will cease and the car will be declared
illegal. The official must see the tech item in question and may ask
the team to show them the tech item for further inspection.
h. Only
the following persons will be allowed at a protest: In the teardown
area only OSP officials, OSP management and two (2) members of the
protested racing team handling the removal of the protested components.
After the protested components have been removed and turned over, only
OSP officials, OSP management, one (1) person of the protested team and
one (1) person of the protesting team will be allowed into the
inspection room or area to determine the legality of the protested
components.
i. All
drivers (including those not directly involved with the protest) are
reminded they are responsible for their crew and fans at all times.
Misconduct or behavior that is detrimental to the protest process may
result in forfeiture of the protest bond and/or ceasing of the protest
procedure with additional fines and/or suspensions levied against those
teams disrupting the protest procedure. This includes team members, car
owners and fans of other race teams. Respect the task at hand.
j. Any
car protested for a P & G check must have the car ready for
inspection within thirty (30) minutes after the completion of the
feature event. Head and engine removal protests must have their engines
ready within one (1) hour after the completion of the race. Unless
these time limits are observed, a car may be declared illegal.
4. Protests in the Street Stock, Mini Stock and Pure Stock divisions. a. P & G fee is $75 (track retains $40). P&G is considered one item.

6. On P & G check only, any car protested where P &
G shows engine to be larger than legal size (at 180 degrees engine
temperature) must have head removed
for additional checking (at no cost to the protester). If the engine
checks less than the legal
size, then the engine is declared legal. If the protester is not
satisfied, he may add an additional cash bond of
$200 and the protested car’s heads will be removed for additional
checking. This must also be in writing prior to the
beginning of the P & G protest and accompanied by the
additional cash bond. If the additional cash bond is not used,
the additional money will be returned. APPEALS
