g 2008 GENERAL RULES
DISCLAIMER
1. The NASCAR/Southern National Raceway Park (SNRP) rules
are designed to provide for the orderly conduct of stock car racing events and
to reduce the always present risk of injury to both participants and spectators
during such events. A NASCAR sanctioned race is a competitive sporting event,
the conduct of which is governed by NASCAR officials. Ultimately, the solution
for unauthorized or improper officiating lies not in individual challenges
seeking to undo what has been done, but pressure brought upon the officials in
charge by drivers, owners, fans, and even NASCAR to improve the caliber of the
race supervisor.
2. It is ultimately the obligation of each participant to
insure that his conduct and equipment comply with all applicable NASCAR/SNRP
rules and regulations as they may be amended from time to time. No
express or implied warranty of safety shall result from publication of, or
compliance with these rules. 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.
3. No driver, car owner, crew member, or anyone else shall
have any claims for damages, expenses, or otherwise against the track or its
officials or anyone associated with NASCAR or Southern National Raceway Park.
NOTICE

SECTION 1
1.1. Application This general rules section applies to each
and every racer, mechanic and/or all pit personnel. Some items, obviously, do
not apply to each class. You can easily determine which rules do not apply to
you. You are expected to know the rules. Ignorance will not be tolerated as an
excuse.
1.2. GENERAL STATEMENT
1.2.1. The rules and/or regulations set forth herein are
designed to provide for the orderly conduct of racing events and to establish
minimum requirements for such events. These rules shall govern the condition of
all Southern National Raceway Park events. By participating in these events,
all participants, guests, race members and staff are deemed to have complied
with these rules. The race director shall be empowered to permit minor
deviation from any of the specifications herein or impose any further
restrictions that in his opinion do not alter the minimum acceptable
requirements. NO EXPRESSED OR IMPLIED WARRANTY OF SAFETY SHALL RESULT FROM
ALTERATION OF SPECIFICATIONS. Any interpretation or deviation of these rules is
left to the discretion of the officials. THEIR DECISION IS FINAL!
1.3. CONDUCT
1.3.1. Any fighting or reckless driving in the pit area may
subject the offender to suspension depending on the seriousness of the incident
and the decision of management. Any continued problems from the same individual
may result in permanent suspension. A fine of $500 or greater may be assessed
to each participant of a fight. The NASCAR Rule Book may dictate additional fines
and/or penalties for the offense.
1.3.2. We demand courteous conduct from all participants at all
times. We will not tolerate profanity in front of race fans, officials, or
management. Any text and/or graphics displayed on your race car found to be
profane or offensive in any way are strictly prohibited. We expect you to look
like a professional and act like one. Be clean, uniformed and look respectable.
1.3.3. Penalties and fines for violation of the conduct, race
procedure and general rules may be implemented per the NASCAR Rule Book to all
participants (NASCAR members and non-members) at the discretion of the
officials.
1.3.4. At any time, the display of any type of weapon or threat
of bodily harm may result in permanent suspension for the driver and/or crew
members and may also result in arrest of all parties involved. This offense may
also be subject to a $500 fine by NASCAR. The NASCAR Rule Book may dictate
additional fines and/or penalties for the offense.
SECTION 2: BENEFITS
AND INSURANCE

BENEFITS
2.1.1. Call Southern
2.2. BENEFIT PLAN
2.2.1. Each participant with a competitor or pit permit who has
signed the release sheet for the event for which the permit is issued is
eligible for benefits if he is accidentally injured as a result of external
violent and visible means while participating in said event. All competitors
agree to abide by decisions of the Benefit Plan officials in administering the
benefit plan. The benefit plan applies only at events and not while traveling
to and from the event.
2.3. GENERAL
INFORMATION
2.3.1. No participant
will be allowed in the pit area without a valid NASCAR license or an SNRP Track
license for minors and until he or she has secured a
competitor or pit permit and signed the waiver and release sheet for that
particular event.

not to be signed by anyone except the person to whom they are issued.
2.3.3. Southern

REPORT IS FILED PRIOR TO LEAVING SNRP PROPERTY ON THE DAY THE ACCIDENT OCCURS.

will negate any claim of benefits covered under the benefit plan.

4.3.2. No one may participate in race events without being registered.
4.3.3. All divisions must display car # on the back of their trailer

SECTION 5: SAFTEY
5.1. Stock car racing is an inherently dangerous sport. Each member
assumes that risk when he or she participates in an event. The risk of serious
injury or death cannot be eliminated and, in fact, will always be present at a
high level. Members are required to advise their spouses and next to kin, if
any, of this fact.
5.2. Although safety generally is everyone’s concern, NASCAR
cannot be and is not responsible for all or even most aspects of the safety
effort. NASCAR AND NASCAR EMPLOYEES AND REPRESENTATIVES OF NASCAR USUALLY ARE
NOT IN ATTENDANCE AT NASCAR WHELEN ALL-AMERICAN RACING SERIES EVENTS, AND
THEREFORE ARE NOT IN A POSITION TO OBSERVE OR HAVE KNOWLEDGE OF UNSAFE
PRACTICES, TRACK CONDITIONS, RACE CARS AND RACING EQUIPMENT. NASCAR, THEREFORE,
CANNOT AND DOES NOT TAKE RESPONSIBILITY FOR THE ADEQUACY - FOR PURPOSES OF
SAFETY - OF THE RACING FACILITY, SAFETY PERSONNEL OR EQUIPMENT, OR CONDITIONS
AT THE TRACK. In the NASCAR Whelen All-American Racing Series, the
responsibility for safety rests exclusively on the various participants in the
Event(s) as follows:
A. Promoter: The Promoter is directly and finally
responsible to ensure that the racing facilities are adequate for the event; that
adequate safety personnel and equipment are provided for each event, both for
the purpose of preventing injury where reasonably possible and responding to
injury when it occurs; and that the conditions at the racing facility are
maintained in a reasonable manner to reduce the risk of injury, all as more
fully set forth in the Sanction Agreement applicable to the event.
B. Competitors: All Competitors are obligated to inspect for
any unsafe condition with respect to the racing facilities, his/her race car
and all related equipment, safety personnel and equipment, and conditions at
the track on a continuing basis before, during, and after the Event. Competitors
must report to the promoter and track officials promptly any inadequacy or
unsafe condition in the facilities, race car, personnel, equipment, or
conditions at the track. Competitors also are solely and directly responsible
for the safety of their race cars and racing equipment and are obligated to
perform their duties (whether as a car owner, driver, or crew member) in a
manner designed to minimize the degree of possible risk of injury to themselves
and others. NEITHER NASCAR NOR THE PROMOTER CAN OR WILL BE RESPONSIBLE FOR THE ADEQUACY
OF A COMPETITOR’S RACE CAR, RACING EQUIPMENT, OR RACING ACTIVITY TO ACCOMPLISH THIS
PURPOSE.
C. Track Officials: Track Officials should report promptly
to the Promoter any observed safety inadequacies in the racing facilities,
safety personnel, equipment, and/or conditions at the track. In addition, if a
track official observes any safety inadequacy in a competitor’s race car,
racing equipment, or conduct, the track official may take whatever action is
deemed reasonable and appropriate in order to correct such inadequacy. Such
action may include, but is not limited to, physical examinations, medical
determinations, and driver ability or experience tests. The competitor is
obligated to follow the track official’s directives. NASCAR IS NOT RESPONSIBLE FOR
THE ACTIONS OR INACTIONS OF ANY TRACK OFFICIAL AS IT PERTAINS TO SAFETY, OR FOR
THE ADEQUACY OF A COMPETITOR’S RACE CAR, RACING EQUIPMENT, OR RACING ACTIVITY
TO ACCOMPLISH THIS PURPOSE.
5.3. Each Competitor agrees and consents that in the event of
injury or death in the course of or as a result of an event, NASCAR may obtain
access to and copies of any and all medical records of the competitor related
to such injury or death.
5.4. PERSONAL SAFETY
EQUIPMENT
A. General
1. Each
Competitor is solely responsible for the effectiveness of any and all personal
safety equipment used during an event. NASCAR, SNRP officials, SNRP management,
and/or promoters are not responsible for the effectiveness of any personal
safety equipment.
2. Each
Competitor is expected to investigate and educate himself/herself fully with
respect to the availability and effectiveness of personal safety equipment.
3. The
Promoter will be solely responsible for determining whether to mandate
particular equipment, and may establish Local Track Rules with respect to such
equipment. Each Competitor is solely responsible for familiarizing
himself/herself with such Local Track Rules. NASCAR strongly recommends, however,
that each Competitor consider the use of and follow the guidelines regarding
such equipment, as set forth in the remainder of this subsection.
4. Passengers
will not be permitted in or on a race car at any time.
B. PROTECTIVE CLOTHING
1. Each
driver should wear a fire resistant uniform.
2. Each
driver should wear fire resistant accessories that effectively cover the
remaining parts of the body.
3. During
race conditions, any crew member who steps into the car servicing area should
wear a fire resistant uniform.
4. Each
crew member should also wear fire resistant accessories that effectively cover
the remaining parts of the body.
5. During
race conditions, any crew member involved in fueling the car or handling and
transporting fuel in the garage or pit area, if any, should have all parts of
the body protected by fire resistant clothing and/or equipment.
6. It
is the responsibility of the driver and crew member, not NASCAR, track
officials, or the promoter, to insure that he/she maintains, wears, and
properly uses protective clothing.
C. OTHER SAFETY DEVICES
1. Each
car should have, within the driver’s reach, built-in, fully charged DuPont
FE-36 or equivalent fire extinguishing equipment with an operating pressure
gauge that is visible with the driver in the car. The fire extinguisher should be
securely mounted with a metal bracket beyond the right side or to the rear of
the seat.
**Note on the
Use of DuPont Halon Fire Systems**
“As the
racing industry began evaluating the use of alternative systems with low or no
ozone depletion potential (ODP), the SFI Foundation, Inc. (SFI), a non-profit
organization created to issue and administer standards for
specialty/performance automotive and racing equipment, established a new
standard, SFI 17.1. This new guideline set the requirements for system design
and hardware, as well as for live fire testing scenarios in order to assure the
system would suppress a fire. Part of SFI 17.1 requires re-testing every four
years or when there are any changes in the hardware to confirm that the systems
perform as expected. Rules governing the use of halons (40 CFR Part 82, Subpart
H) state that halons cannot be vented during testing or training. This means
halon systems that are currently in use cannot be recertified.”
As a result, halon systems will not be allowed in all sanctioned auto racing
after December 31, 2007, and the motor sports industry will be required to
replace all existing halon systems. Many teams have already started installing
hydrofluorocarbon (HFC) systems that use DuPont™ FE-36™ clean agent fire
extinguishant. DuPont™ FE-36™ is becoming the preferred alternative to halons
because it meets the SFI 17.1 standard, has zero ODP, and is safe for use where
people are present, such as driver compartments. Once halons are no longer
permitted, the environment will benefit from better protection. Fortunately,
effective fire extinguishant alternatives are readily available for the racing
industry”.

2. Any
car that is not equipped with a built-in fire extinguisher should have an
adequate fire extinguisher, with an operating pressure gauge, visible with the
driver in the car, securely mounted beyond the right side or to the rear of the
seat with a metal bracket.
3. All
entrants should have in their hauler and/or pit area, if any, as part of their
equipment at all times a fully charged minimum 10 pound dry chemical, FE-36, or
its equivalent fire extinguisher with a visible, operating pressure gauge.
5.4.1. HELMETS, HEAD
AND NECK RESTRAINT DEVICES
A. Helmets
1. Drivers
should wear a helmet carrying at least a valid SA 1995, SA 2000, SA 2005
Standard Snell and/or a valid SFI 31.1, SFI 31.2 or SFI 31.1/2005 label at all
times on the race track.
2. The
driver should wear the helmet in accordance with the directions provided by the
helmet supplier and/or manufacturer. Any modification to the helmet for any
purpose should not detract from its effectiveness.
3. During
race conditions, any crew member who steps into the car servicing area should
wear a helmet.
4. During race conditions, any crew member involved in
fueling the car should wear a full face helmet and a fire resistant head sock.
B. Head and Neck
Restraint Devices/Systems
1. At
all times during an Event (practice, qualifying and competition), drivers
should connect their helmet to a NASCAR approved head and neck restraint
device/system. The head and neck restraint device/system, when connected,
should conform to the manufacturer’s mounting instructions, and it should be
configured, maintained and used in accordance with the manufacturer’s
instructions.
2. It
is the responsibility of the driver, not NASCAR, SNRP Officials or promoter, to
insure that his/her device/system is NASCAR approved, correctly installed,
maintained, and properly used.
3. Currently
the HANS Device and the Modified Hutchins Device are the NASCAR-approved head
and neck restraint systems.
5.4.2. SEAT BELTS
A. Each car should be equipped with a NASCAR-approved seat
belt restraint system. The seat belt and shoulder harness should not be less
than three (3) inches wide except for use with the HANS Device. When used with
the HANS device the shoulder harness should not be less than two (2) inches wide
as it passes over the HANS Device. Approved seat belt restraint systems should
have a latching mechanism attached to the lap belt. This latching mechanism
should provide a common connection and release for the lap belt, shoulder
harnesses and the anti-submarine belt(s), and should be designed with a quick
and easy one- handed, gloved release of all belts in all conditions. It should
have one (1) of two (2) approved release designs:
1. Latch/Lever:
Utilizes a lever opening away from the body in a right to left hand movement,
parallel to the lap belt with a complete release of all belts. The lever should
have a provision to prevent an unintentional release.
2. Cam
Lock: A circular handle or raised surface that turns in both directions for a
motion of not less than 30 degrees before completely releasing all belts. A
downward facing tab or toggle may be used, provided that its length does not
extend more than 1/2 inch beyond the outer diameter of the release mechanism
unless a provision to prevent unintentional rotation or release is provided.
B. The seat belt restraint system should be installed in
accordance with the directions provided by the system supplier and/or
manufacturer. In addition, please note the following guidelines:
1. Lap
belts should be installed and used in such a manner that, when secured to the
latching mechanism, the seat belt webbing travels in a straight, clear and free
path from the belt mount through the seat opening to the latching mechanism. When
the driver is buckled in the seat, the free end of the seat belt webbing should
rest in a position clearly aligned over the seat belt webbing entering any
adjustment or latch release hardware.
2. If
a roller adjuster is used on the left lap belt it should have tension springs
installed and it should be attached to and be part of the latch release
mechanism directly with no webbing loop. The roller adjuster should not be
attached to the lap belt mounting tab at the frame. A 3-bar slider, threaded to
the manufacturer’s instructions, may be used for the left lap belt length
adjustment, in the absence of the roller adjuster. The 3-bar slider should be
positioned outside the seat opening and as close to the mounting tab as
possible. On the right lap belt, if a roller adjuster is used, it should have
tension springs installed and the adjuster may be located anywhere on the belt except
at the frame mounting tab. A webbing link may be used to connect the roller
adjuster to the latching mechanism. A 3-bar slider, threaded to the
manufacturer’s instructions, may be used for the right lap belt length
adjustment, in the absence of the roller adjuster. The three bar slider should
be positioned outside the seat opening and as close to the mounting tab as possible.
Wrap-around style lap belt mounts and hook/eyebolt style mounts should not be
permitted; only tab style lap belt mounts secured with a nut and bolt should be
permitted.
3. Shoulder
belts should mount to horizontal shoulder bar (#7) or shoulder belt bar (#7B)
only. Only individual shoulder harness belts should be permitted. The seat
opening should be a single or double open slot with a finished inside edge or grommet.
Y-type shoulder harnesses should not be permitted. Wrap-around shoulder harness
mounts should be permitted provided the belts do not cross behind the driver
and all the wrap-around mount style shoulder belts should be retained by a
guide on horizontal shoulder bar (#7) or shoulder belt bar (#7B) to prevent
lateral movement of the belt on the roll bar. Shoulder belts may cross behind
the driver provided they use a tab style mount and not a wrap-around mount.
Each shoulder belt using a tab mount should use an individual mounting tab or a
steel sleeve welded through horizontal shoulder bar (#7) or shoulder belt bar
(#7B) and be secured with a nut and bolt. The seat opening should be a single,
open slot with a finished inside edge or grommet where the shoulder belts cross
behind the driver. Roller adjusters on the shoulder harnesses should have
tension springs installed. Sternum or cross belts using metal or hard surface
hardware should not be permitted.
4. Approved
6-point anti-submarine belts should be mounted to the seat frame or a steel
reinforced seat bottom mount. Either wraparound or tab style anti-submarine
belt mounts should be permitted on 5-point or 6-point belts.
C. The manufacturer’s label should not be located under the adjusting
mechanism when the driver is buckled in the seat and has tightened the seat
belts and shoulder harness. If the label is under the adjusting mechanism, the
label should be removed or relocated in a manner that does not affect the integrity
of the belt material. The date of manufacture should remain visible on the
belts at all times. Seat belt restraint systems should not be used beyond
two (2) years after their date of manufacture.
D. The driver should use the seat belt restraint system at
all times on the race track, in accordance with the instructions and/or
recommendations of the system supplier and/or manufacturer, as set forth above.
E. It is the responsibility of the driver, not NASCAR, SNRP Officials,
or the Promoter to insure that his/her seatbelt restraint system and all
components are NASCAR-approved, correctly installed, maintained, and properly
used.
5.4.3. SEATS
A. Custom-manufactured aluminum seats constructed from solid
aluminum sheet materials from the seat bottom to above the driver’s shoulders
will be permitted if acceptable to SNRP Officials. Holes and/or other
modifications that, in the judgment of track officials, were made with the
intent of weight reduction will not be permitted.
B. All aluminum seats should have padded side protectors and
padded aluminum seat leg extensions on the left and right side.
C. A headrest acceptable to Track Officials should be used.
All headrests and hard surfaces around the driver’s seat should be padded with
impact absorbent material.
D. Strap-type headrest supports or nets should be equipped with
a quick release fastener.
E. The upper seat back should be secured to horizontal shoulder
bar (#7) or to a bracket that is secured to horizontal shoulder bar (#7) with a
minimum of three (3) high quality bolts. The seat bottom should be secured to
the car’s structure with a minimum of two (2) high quality bolts per side. When
mounting through aluminum seats or brackets, large diameter washers should be
used.

1. 1st Infraction
Disqualification of that race - 0 points, $0.00 in prize
money won during the race, including, but not limited to Pole Award; SNRP
suspension of the next (2) race weekends at that participants home track (for
example - if Tom Smith is suspended for 2 races and the next 2 races are rained
out, Tom Smith will remain suspended until 2 separate nights have passed where
racing has occurred at that speedway. This allows for the possibility of Tom
Smith missing 4 races.); probation for the remainder of the current season; and
a SNRP Fine of $1,000.00. The racer will not be allowed to race at SNRP until
the fine has been paid.
2. 2nd Infraction
Disqualification of that race - 0 points, $0.00 in prize
money won during the race, including, but no limited to Pole Award; SNRP
suspension of the next (4) race weekends at that participants home track (see

been paid and a sufficient amount of time served for suspension has passed.
Once that racer returns, he/she will be on probation (length to be determined).
ADDITIONALLY, each time a crate engine has been found illegal, that track will
confiscate the engine. The engine will be unbolted at the bell housing and
removed. Everything, including, but no limited to, the carburetor, engine
mounts, clutch, belts, air cleaner/filter, and the oil pan will be removed from
the racecar and confiscated by the track. IT WILL NOT BE RETURNED UNDER ANY

a claim exchange is approved, both carburetors must be left at the track and at
the next race, the Track Officials will ensure that the carburetor are put on
and run. The Track reserves the right to deny any request for a Claim/Exchange.
Additionally, the owner of the claimed carburetor may opt to have the claimer
buy his carburetor for a fee of $800.00. (This forfeits the $200.00 Claim Fee & the driver
of the claimed carburetor will not receive the other’s carburetor.) The Track
reserves the right to deny any request for a Claim. SNRP reserves the right to
an exchange at any time during the night with any competitor. This will be a

RULES AND PENALTIES
A. Balancers must be original. They cannot be changed.
Everything must be the original equipment. NO EXCEPTIONS.
B. If during technical inspection, at any time, a racer’s
crate engine is found to have been altered, tampered with, or wrong for any
reason whatsoever, the engine is illegal.
The penalty for this is as follows:
1. 1st Infraction
Disqualification of that race - 0 points, $0.00 in prize
money won during the race, including, but not limited to Pole Award; NASCAR
suspension of the next (2) race weekends at that participants home track (for
example - if Tom Smith is suspended for 2 races and the next 2 races are rained
out, Tom Smith will remain suspended until 2 separate nights have passed where
racing has occurred at that speedway. This allows for the possibility of Tom
Smith missing 4 races.); probation for the remainder of the current season; and
a SNRP Fine of $1,000.00. The racer will not be allowed to race at SNRP until
the fine has been paid.
2. 2nd Infraction
Disqualification of that race - 0 points, $0.00 in prize
money won during the race, including, but no limited to Pole Award; SNRP
suspension of the next (4) race weekends at that participants home track (see
above example of Tom Smith; he may now miss 8 races); probation for the
remainder of the current season; and a SNRP Fine of $2,000.00. The racer will
not be allowed to race at SNRP until the fine has been paid.
3. 3rd Infraction
Disqualification of that race - 0 points, $0.00 in prize
money won during the race, including, but no limited to Pole Award; SNRP
suspension for AT LEAST the remainder of the current season; and a SNRP Fine of
$5,000.00. The racer will not be allowed to race at SNRP until the fine has been paid and a
sufficient amount of time served for suspension has passed. Once that racer
returns, he/she will be on probation (length to be determined). ADDITIONALLY,
each time a crate engine has been found illegal, that track will confiscate the
engine. The engine will be unbolted at the bell housing and removed.
Everything, including, but no limited to, the carburetor, engine mounts,
clutch, belts, air cleaner/filter, and the oil pan will be removed from the
racecar and confiscated by the track. IT WILL NOT BE RETURNED UNDER ANY
CIRCUMSTANCES.
C. There will be no claim or claim/exchange on the crate
engines by competitors. SNRP has the right to pull an engine and check it at
any time. If it is wrong, the above penalties will apply. If it is right, the
Track will return the engine in a timely manner. SNRP reserves the right to
impound anyone’s car and/or any part of anyone’s car for the purpose of
technical inspection. SNRP will impound the car until the racer agrees to allow
his car to be inspected.
D. Any crate engine torn down at the request of SNRP and found to be legal,
SNRP will pay a nominal fee for gaskets only (All protest rules apply as well).
E. All crate engines are subject to Dyno testing or tear
down at any time.
F. All crate engines that need to be freshened or repaired
should contact the track for service through a certified engine builder.

and size of the filter must be acceptable to Track Officials.
D. Fuel injection and superchargers are not permitted.
E. If a carburetor does not pass technical inspection after
the race, the racer will be disqualified for that night and forfeit all points
and prize money. The racer will receive 0 points and $0.00 in prize money. The
carburetor will be confiscated by the track and will not be returned. A $500.00
NASCAR fine will be levied. The racer will not be allowed to race at any NASCAR
track until the fine has been paid. If a carburetor does not pass technical
inspection after Qualifying, but BEFORE the Green Flag, the carburetor will be
confiscated, a $500.00 Track fine will be levied, all winnings up to that point
will be forfeited, and the racer will start at the rear of the field. The racer
will not be allowed to start the race that night or any other races at a NASCAR
track until the $500.00 fine has been paid. (The only things that can be
changed on the carburetors are the power valves and jets. If anything else is
different, then the carburetor is illegal.)
9.5.8.1. Carburetor
Claim/Exchange
A. Any racer that finishes in the Top 5 will have the option
to claim another competitor’s carburetor that finished in the Top 5 that same
race (only like carburetors may be exchanged e.g. 500 to 500). The claim fee is
$200.00. Both carburetors must pass technical inspection before exchanging. If
a claim exchange is approved, both carburetors must be left at the track and at
the next race, the Track Officials will ensure that the carburetor are put on
and run. The Track reserves the right to deny any request for a Claim/Exchange.
Additionally, the owner of the claimed carburetor may opt to have the claimer
buy his carburetor for a fee of $800.00. (This forfeits the $200.00 Claim Fee & the driver
of the claimed carburetor will not receive the other’s carburetor.) The Track
reserves the right to deny any request for a Claim. SNRP reserves the right to
an exchange at any time during the night with any competitor. This will be a
straight exchange with no money switching hands. SNRP reserves the right to do
a straight exchange, at any time, with a track carburetor.
