INTRODUCTION
Welcome to the World Racing League! WRL is a grassroots road racing club created on the premise that road
racing should be simple, fun and affordable while remaining safe and professional. WRL is a non-contact series
open to cars and drivers running in other clubs and organizations, and does accept novice drivers into a simple
but structured licensing program. WRL is inclusive, if you want to race, you are welcome here!

Please read the entire rulebook. It's short and sweet with a bit of levity thrown in so you don’t fall asleep. Our
rules were created to be general in nature for simplicity, but still provide enough detail to give you a concrete
idea of what is expected to enter, prepare for, and safely participate in a World Racing League event. If after
reading this rulebook you find that you still have questions, feel free to contact us at 800-377-0944.

Here’s the obligatory warning: You are about to engage in auto racing. Contrary to popular belief, piloting a
race car at breakneck speeds is physically, mentally and emotionally demanding. Possible side effects of driving
a car in a road race include but are not limited to: Elevated heart and respiratory rate, elevated blood pressure,
overheating/heat stroke, dehydration, over-exertion, exhaustion, and can otherwise aggravate or complicate
existing or underlying medical conditions. If you just broke out into a cold sweat, relax. It’s still relatively safe!
But only you and your doctor can assess your physical fitness for road racing ('cause we don't want to see you
naked in our office - even if we had one). If you know you have, or have any reason to suspect that you may
have any health-related issue that could be triggered or aggravated by this activity, see your physician before
getting in a race car!

Disclaimer: Despite the extraordinary advances in safety technology and all industry-standard safety
precautions, auto racing carries an inherent risk of property damage, personal injury and even death.
Observance of, and strict adherence to safety requirements, instructions, rules and precautions can reduce, but
not eliminate, these risks. All participants acknowledge that they are participating at their own risk, and hold
harmless World Racing League Racing LLC, its owners, officers, officials, associates, sponsors and assigns. You
and only you are responsible for adhering to the safety regulations set forth in these rules.

World Racing League is not responsible for medical expenses, repair bills, damages or any other loss you may
incur during a World Racing League event. However, you can be held financially liable for damages you cause to
track property or World Racing League property. Yes, even if it's accidental.

Anyone refusing to sign the insurance waiver will be denied admittance to World Racing League events.

And finally, a friendly bit of advice - No one here likes a "rules lawyer". We appreciate your input, but ultimately
our interpretation of the rules is the only one that matters.

So now that we've dispensed those little nuggets of wisdom, let's look at just how easy is it to race with this
stupendously awesome outfit. Just follow our simple 5-step process:

and forms, download the “Novice Guide in the “Rules” section of the website
c. Note that some events may restrict the participation of novice drivers. It’s not personal, we still love you

C. PREPARE YOUR CAR TO RACE
1 Car Eligibility: Mass-produced passenger cars or trucks sold in North America regardless of year model. WRL
allows you to build a bona fide race car. Some modifications are “open” giving you leeway in applying them
to your platform. Others, while still allowed, may affect which class your car falls into. See ‘APPENDIX B -
Vehicle Performance Preparation and Classification’ for more info. Many cars racing in other organizations
are eligible, including Performance Touring, Spec Miata, Production, Improved Touring, Street Stock, Spec
Boxster, and various budget endurance racing series. Questions about your car? Call us!
2 Log Book: World Racing League will issue each car a log book. Once issued, it is your responsibility to have it
at every race and produce it on demand. Don't leave home without it, we take your beer money if we have
to re-do all your paperwork at the track
3 Safety Requirements: The following are the minimum safety requirements we expect (demand) to see on
and in your car. Feel free to build your car to exceed these standards:
a. Roll cage: A full roll cage is required, equivalent to those generally required by SCCA, NASA, LeMons, and
others. Yes there are some exceptions. See APPENDIX A for WRL roll cage specifications. We get final say
on whether your cage passes or not, get it right!
b. Fire Suppression: At a minimum, each car will carry a fully charged 2.25lb fire extinguisher rated A:B:C,
mounted in the cockpit in plain view using a metal mounting system with a quick-release. No plastic
allowed. A properly installed fire suppression system of at least 2.3 liters capacity is recommended.
Electrically operated fire systems must be wired directly to the battery. “Circle E” extinguisher decal must
be displayed on the exterior of the car to indicate the general location/access to the fire bottle/trigger
c. Master Kill Switch: Switch location is open as long as it can be deactivated by the driver while secured in
the seat. Switch must isolate battery from all circuits and must interrupt the ignition circuit. Positive
terminals of the battery and switch must be insulated. A “Master switch” decal with the universal
“lightning bolt” and the word “OFF” must be displayed on the exterior as near to the switch as possible
d. Battery: Must be properly secured. If mounted in the cockpit, any non-AGM battery must be enclosed in a
battery box
e. Harness: 5, 6, or 7 point racing harnesses with current FIA or SFI rating are required to be installed and
used per manufacturer specifications (FIA certs are valid for 5 years, SFI for 2 years). Sub belts and laps
belts must be attached to structural members or bolted through floor with 3" dia. (minimum) backing
washers or plates. Shoulder straps must be properly secured to harness bar. Reputable manufacturers
provide instructions, read and follow them
f. Window Net: Must be installed so that driver's head or arm cannot extend outside the plane of the driver's
window while seated. Net must be secured to the cage and must be easily removed at the top using a
quick release system. Do not attach window net to door. Arm restraints are an acceptable alternative to
nets when used properly, and are required for convertibles. Be safe. Stuff happens
g. Seat: One-piece seat designed specifically for auto racing is required. Seat must be mounted at a minimum
of four points at the base. If bolting through the floor, 3" dia. washers or backing plates are required. If the
seat back will be more than 3" from the harness bar for any driver, a seat back brace must be installed to
prevent rearward movement of the seat. Back brace can be adjustable but must not present a risk to the
driver by its design or installation
h. OEM Safety Systems: Ignition locks must be disabled. Airbags must be disabled and removed

plastic vessel enclosed in metallic can and be manufactured by ATL, Fuel Safe or JAZ. Other
manufacturers may be approved, contact us for more information
ï‚· Cell must be properly protected, plumbed and vented. Since there is an infinite number of possibilities
on location and installation, WRL officials will make the final determination on what is a proper and safe
installation. If there is any doubt, ask questions before tech
ï‚· Fuel, brake or oil lines passing through the passenger compartment must be rigid metal tubing or steel-
braid armored, free of damage, kinks or leaks
h. Firewalls: Firewall must be present between fuel cell/fuel tank and the driver, and between the engine and

D. SHOW UP AT THE RACE
1 Arrival: Check the Event Race Information sheet for specific information related to arrival time, parking, etc.
2 Vehicle Inspection: Cars must be inspected by World Racing League officials prior to racing. While most
everything else is fun and games, this is where we get serious-
a. All cars will be scrutinized for:
 Weight – cars will be weighed by WRL without driver and CoolShirt water each time they are inspected
ï‚· Adherence to safety requirements
ï‚· Proper cage design and construction
ï‚· General safety issues including leaks, loose parts, etc.
ï‚· General preparation requirements, including modifications
b. The team captain or a representative will bring the car to the inspection location identified in the Race
Information sheet prior to the car's first race and annually thereafter
c. Each car will undergo two types of inspection:
 Safety Inspection will be on an annual basis and will be recorded in the car’s log book. A World Racing
League Annual Safety Inspection sticker will be issued to cars that pass. The sticker must be placed in
plain view on the front hoop, main hoop or rear stay of the roll cage on the driver’s side so that it may
be seen at Black Flag. Lost or missing stickers will incur a $25 fine unless you can produce the original
 Preparation and classing inspection will be completed prior to a car’s first race with WRL, or as needed
thereafter (see section d. below). Each team must present a World Racing League Log book filled out for
the car to be inspected. Upon passing scrutiny, WRL officials will assign your car to the appropriate Class
(See Appendix B). You must disclose all modifications that are not allowed in Appendix B. Undeclared
modifications or attempts to hide modifications will make your car ineligible for a podium finish
d. A car that has been modified, wrecked, rolled, upgraded, downgraded, or that has undergone major repair
or a weight change since its last inspection must be re-inspected. This includes major repairs at a race
e. Officials may suspend your car from racing at any time until any outstanding issues are resolved
f. Altering or forging Inspection stickers or log books will result in a penalty as determined by World Racing
League officials, up to and including indefinite suspension from the series
g. All rulings of the officials are final
3 Check In: Unless otherwise specified in the Race Information sheet, only the Team Captain is required to
report to the Check In desk to receive his/her team’s credentials and complete registration
a. Team Captains will verify payment, car number, and transponder number at the Check In desk
b. The Team Captain must also bring the car's log book to Check In. Cars without current log books will not be
permitted to race
c. All team members must be listed along with their emergency contact information
d. Transponders will be available at the Check In desk for those in need. Securely mount the transponder as
low to the ground as possible, with a clear, unobstructed view of the track below. You are responsible for
loss of, or damages to, a rented transponder
4 Driver’s Safety Gear Inspection: All drivers must present their required safety gear for inspection annually. A
valid Annual Equipment Inspection sticker must be worn on the left side of the driver's helmet in order to go
on track. It is each driver's responsibility to wear the required safety gear while in the car. Non-compliant
drivers will not be allowed on track
5 Social: After Inspection and Check In are closed for the day, participants are invited to join World Racing
League staff for a social activity as announced in the event's Race Information sheet. Have a band? Own a
beer distributorship? Like to smoke large chunks of meat? Contact us. It could reduce the cost of your racing!

World Racing League Rules and Procedures

E. RACE!
1 Race Formats: World Racing League runs one- or two-day endurance races lasting up to 24 hours as well as
combined HPDE/enduro weekends. The specific format, fees and schedule for each race will be outlined in
the Race Information sheet for each event. In any case, you'll get all the seat time you can handle!
2 Racing Rules:
a. Contact: World Racing League is a non-contact racing club. To avoid contact, all drivers should maintain
racing room at all times and in all situations. "Racing room" is defined as allowing all competitors room to
maneuver their car on the racing surface, or more simply put, giving your competitor a lane to race in
b. World Racing League defines contact in 3 categories-
ï‚· Incidental Contact: Minor contact incidental to close-quarters racing that leaves no damage nor moves a
car off its line. Example: an unintentional side-to-side bump while going two wide in a turn. No penalty
unless repetitive. Repeated incidental contact will be treated as Avoidable Contact
ï‚· Unavoidable Contact: Any contact that damages a car or moves a car off its line, but where one or more
drivers could not reasonably be expected to avoid the contact. All parties involved will be Black Flagged
ï‚· Avoidable Contact: Any intentional contact, repeated contact, contact resulting from reckless or careless
driving, or any contact where a driver could have taken reasonable measures to prevent or avoid the
contact incident. All parties involved will be Black Flagged
c. Multiple or subsequent contacts by the same team, regardless of driver(s) involved or contact type, will
increase the severity of the penalty assessed up to and including probation and/or removal from the series
d. Passing: Safe and drama-free passing requires that everyone adhere to the following passing rules-
ï‚· Making a pass: It is your responsibility to plan and execute a safe pass, maintain racing room at all times
ï‚· Being passed: It is your responsibility to check your mirrors, hold a consistent line, be predictable, use
hand signals and to maintain racing room at all times
ï‚· Safe pass: A safe pass is defined as a pass where no contact takes place and no car involved in the pass
spins or leaves the racing surface, because all parties maintained racing room at all times. If a car is next
to you and you deprive him of racing room by causing contact or "squeezing" him off the track, you have
violated safe passing etiquette and will be Black Flagged
e. Unsafe and dastardly maneuvers: "Dive bombing" into corners, chopping, and blocking are unsafe
maneuvers and may result in a penalty. Driving like an asshat is frowned upon in this establishment.
f. Loss of control: A spin or four wheels off incident resulting from a lack of control or over driving the
car/course will result in the driver being black flagged for a stop and go penalty on Pit Road. Multiple spins
and/or four-offs by the same driver may require a driver change
g. Reckless or dangerous behavior on course is a black flag offense. Penalty will be at the Steward's
discretion, but will at a minimum require a driver change
h. Driving Stints: Any maximum time per driving stint will be assigned in the Race Information sheet.
However, each driver must have at least 1 hour behind the wheel. Race officials will observe drivers for
signs of fatigue, deterioration of judgment etc. and will act accordingly
i. Timing/scoring: You need an AMB 260X transponder if you want to be scored for the race. Whether you
buy it or rent from WRL, you are responsible for the proper installation and operation of your car's
transponder. We will notify you at the start of the race if your transponder is not being read. WRL is not
responsible for improperly mounted transponders, or team-owned transponders that fail or malfunction.
j. Violations and Penalties: For a list of all race violations and penalties, see APPENDIX C
k. Race- or track-specific rules and regulations can be found in the event’s Race Information sheet
3 Fueling: Fueling will take place on Pit Road only during hot track. Driver may remain in the car. Any and all
spills will be cleaned up immediately
a. All crew on the "hot" side of the pit wall must wear helmets/visors, and fire retardant suits, gloves and
shoes while the fuel port is open
b. No more than four team members may be over the wall while the fuel port is open, including the
"fireman". The fireman's sole function will be to man a 10lb ABC fire bottle while fuel is being transferred,
World Racing League Rules and Procedures

Ver: 201501.02 ©2014, 2015 World Racing League LLC Page 9 of 16
standing 7' - 10' from the fuel port on the hot side of the pit wall. The outgoing and incoming drivers
during a driver’s change count as 1 team member
c. The fuel port will not be opened until the engine is off
d. No one may perform any work on the car while the fuel port is open. Driver change is allowed
e. Only fuel jugs with a capacity of 5 US gallons or less may be used to fuel the car. Cross section of the
hose/nozzle or funnel spout may not be larger than 1.0” inside diameter. Jug vents may be modified but
must remain safe. Fuel jugs must be leak free at all times. No pressurized fueling systems allowed
f. Any fuel delivery system found by officials to be unsafe will not be used
g. A drip pan/catch pan must be used where fuel may spill onto the ground while fueling
h. Cars arriving at Pit Out with driver not properly attired and strapped in will sit for a 5 minute penalty
4 Winning: Not that we need to explain this one, but the team that finishes the race in the lead, wins
a. Cars must take the checkered flag to finish the race
b. A car may cross the finish line while not under power but cannot be pushed or pulled across the finish line
by the driver, other drivers, crew members, or spectators
c. Podium cars will be impounded after each race and will expose themselves for inspection by World Racing
League officials and competitors for a period determined by the race officials
ï‚· Podium teams will go straight to Impound upon exiting the track. Failure to do so results in
disqualification
ï‚· Podium teams will display their log book during Impound. Failure to display the log book will result in
disqualification
ï‚· All impounded cars will be weighed without driver and weight verified against their log book
ï‚· A competitor may protest a podium car if he/she finds any undisclosed modification or major rule
violation. All protests will be made to the Chief Steward and held in confidentiality
ï‚· Modifications that were not disclosed at pre-race Inspection will result in disqualification. Other rules
violations will be penalized at the discretion of the officials
ï‚· The outcome of any protest rests solely in the hands of the officials and is final once impound closes
5 Awards:
a. Podium Awards:
ï‚· The top three finishers in each Competition Class will receive Fame, Glory and a World Racing League
team trophy. Individual trophies may be ordered after the event. Each podium team will also receive a
race credit certificate (value depending on event) that may be applied toward a future race
ï‚· Podium teams may receive other awards based on sponsorships, contingencies or event type/duration
b. Other Awards will be given as warranted by your efforts and/or antics before and during the race, and may
include race discounts, trophies, gift certificates, unclaimed children or anything we find on the “impulse
buy” display at the local truck stop checkout counter. You must be present to win
c. Contingency/sponsor awards will be given as outlined in the Race Information sheet

APPENDIX A - Roll Cage Design and Construction Specifications

This section provides the generally accepted minimum roll cage design and construction requirements. Existing
roll cages used in NASA, SCCA, and other national road racing sanctions, if properly built and inspected, should
meet or exceed the standard below. If you are contemplating building a new cage yourself and do not have a
proper tubing bender, welder and notch saw, don't know how to weld or don't understand why cardboard
comes into play in the process, stop here. Take this Appendix and the car to a reputable fabricator and feel
secure in knowing you just made a smart call...

1. General Criteria
a. Professionally designed and built roll cages are highly recommended. This is not something the
untrained or unskilled should attempt to do themselves.
b. Professionally manufactured bolt-in cages are allowed provided they are installed using the
manufacturer-provided or specified tools and hardware and meet the design criteria in Section 2
c. Welds must be professional quality, 360 degrees around every tube joint, with full penetration
d. Minimum tubing size will be determined by the weigh of the car. All tubing will be seamless mild
steel or DOM, ERW is not acceptable unless a waiver is granted for an existing cage
ï‚· Under 2500 lbs - 1.50" x 0.095"
ï‚· 2501 and over - 1.50" x 0.120" or 1.75" x 0.095"
e. Tubing will be Rotary Drawn or Mandrel Bent and properly notched with appropriate tools. Bends
must have a radius no less than 3 times the outside diameter of the tubing and will not show any
signs of crimping, stretching or other potential failure.
f. Any cut made in a firewall to accommodate tubing must be re-sealed once the tubing is installed
g. The use of gussets to strengthen connecting points is open
h. Any portion of the finished roll cage that may be contacted by the driver's helmet, body or limbs
must be padded with roll bar padding
2. Roll Cage Design
a. Main Hoop must be a single, continuous length of tubing with no more than 4 bends, and should
follow the b-pillars and roofline as closely as possible with a rake of no more than 5 degrees off
vertical. The Main Hoop will be tall enough so that any driver's helmet does not extend above a line
connecting the centerlines of the Front Hoop and Main Hoop
ï‚· A diagonal brace will be added in the same plane as the Main Hoop, with one end
connecting at lower right of the Main Hoop at the mounting plate or as closely as
possible, and the other end connecting to the top left (horizontal) of the Main Hoop
within 12" of the bend nearest the driver's head
ï‚· The Main Hoop will be braced with two tubes extending rearward from the top corners
(bends) of the Main Hoop, or within 6" thereof, running straight to the floor, cross
member or strut/shock towers. Rear bracing will not have any bends and should be at a
30-60 degree angle to the plane of the Main Hoop
b. Forward section of the main cage may be one of three configurations:
ï‚· Side Hoops (aka "Forward Hoops"): Tubes extending forward from the top corners
(bends) of the Main Hoop and down to the front floor, following the roof line and a-
pillars as closely as possible, each with no more than 2 bends, and both connected by a
tube running as close to the top of the windshield as possible. (SCCA Production cages
that do not follow the original roof line may qualify, petition the officials before the race
to gain approval), or;
ï‚· Halo: A single tube bent into a "halo" that extends forward from either corner of the
Main Hoop in a horizontal plane to the top of the windshield and follows the roof line as
closely as possible. The front of the halo will be supported from the floor/sill by a
