Sporting Regulations


It is the responsibility of both the overtaking and overtaken Drivers to assure
safe passing at racing speeds. A car traveling alone may use the full width of
the track. Passing may be either right or left depending on the conditions of
the moment.

Throughout the periods of practice, qualifying and racing, access to the pits
must be made through the designated pit entrance. The deceleration zone
before pit entrance and acceleration zone at pit exit shall not be considered as
part of the pits, and no work shall be performed on cars in these areas. IMSA
or the Race Director may impose penalties for driving in the pits which is
deemed dangerous, erratic or of inappropriately excessive speed for the
circumstances. IMSA will impose a speed limit of 60 kilometers/hour in pit

The following signals are used both to advise Drivers of various conditions and
to direct Drivers to obey various specific instructions. Cloth flags are normally
used, but may be replaced with similarly coded rigid signaling boards or with
lights. Steady light is equivalent to a motionless flag; flashing light to a waved

Start of race, or cancellation of a danger previously signaled. Track is clear.

6.3.2 BLUE FLAG Motionless: Another competitor is following you and may be trying to pass you. Waved: Make way for another competitor who is trying to pass you. Blue flag
will normally be used in a case where the overtaken Driver is obviously
unaware of the following car, or is clearly obstructing another car.

6.3.3 YELLOW FLAG Motionless: Danger, no passing, slow down. Motionless yellow flag is
generally used to advise of an obvious danger or to forewarn of a more serious
danger ahead. Drivers should stop racing until they are past the danger zone. Waved: Extreme danger, no passing, slow down, be prepared to stop. Waved
yellow flag may mean imminent and serious danger such as a partial track
blockage, fire on or near the track, or a crowd control hazard. Double stationary yellow flag: Safety car.

6.3.4 WHITE FLAG One (1) lap to go. When the Official Starter displays a waving white flag just
prior to the scheduled conclusion of the race, it means the leader has started
his/her last lap regardless of the elapsed time or distance. The Official Starter
will also normally hold up one finger at this time. Otherwise, the display of a stationary white flag anywhere on the circuit
denotes an ambulance, fire truck, wrecker or other service vehicle is on the
circuit, or a slow-moving race car is ahead.

Slippery surface and/or debris on course.

6.3.6 BLACK FLAG Furled: WARNING. You have committed a dangerous or unsportsmanlike
action. Desist or you will be penalized. Waved: Stop in the pits for a consultation next lap. This flag is usually
displayed along with the number of the car concerned for infraction of rules of
the circuit or act of poor sportsmanship. If a competitor should fail to obey the black flag after it has been displayed to
him/her, the Race Director may instruct the Timekeeper to stop timing and scoring
the car (see also Article 6.3.10).

Your car has a mechanical fault of which you may not be aware. Stop at your
pit next lap.

6.3.8 RED FLAG (see also Article 4.17) The race is stopped. This flag is used exclusively at the discretion of the Race Director to stop the
race and displayed exclusively by the Official Starter. All other corner stations
shall display a black flag. When the red flag is shown, Drivers will slow down to a slow speed and be
prepared to stop at any time. No passing. They will proceed in a line, slowly
and carefully around the circuit to the pits where they will be directed further. Unless it is specifically authorized by the Race Director and announced to all
competitors, no service of any kind may be performed on any cars from the
time the red flag is shown until the race is restarted. This includes cars which
may already be in the pits.

End of a session or end of a race. Return to the pits at reduced speed and
stop at the pits.

6.3.10 BLACK FLAG ALL Interruption of practice or qualifying session. Return to the pits at reduced
speed and do not overtake any other car during your slow lap back to the pits. The Official Starter will display a stationary black flag, all corner stations shall
display a stationary black flag, a waving yellow flag will be displayed at and/or
leading up to the scene of the incident.

6.3.11 SAFETY CAR The Race Director may dispatch the safety car at any time during an event in
order to correct a hazardous situation. Drivers will be warned that a safety car
will be used when all turn stations display two stationary yellow flags. No
passing will be permitted anywhere on the circuit. The safety car will take the
course ahead of the current leader, if possible. All contestants will then follow
the safety car in single file. The primary purpose of using the safety car is to create a traffic interval on the
circuit so that marshals may handle emergencies quicker and more safely;
therefore, it is essential that stragglers catch up with the field as quickly as
possible. It is forbidden for a contestant to pass the safety car unless he/she is
instructed to do so by an IMSA official. Competitors may enter the pits while the safety car is on course, but they may
not re-enter the racing circuit unless directed by a marshal. They must fall into
line at the rear of the field after it has passed the pit area. The safety car will pace the field for a minimum of two laps. The Race Director will instruct the safety car to extinguish its safety lights to
indicate that the end of safety car intervention is about to occur. The safety
car will exit the course at the entrance to pit lane. On the restart, the green flag will be displayed at the Start/Finish line, the
yellow flags dropped, and racing may begin again. Special safety car procedures for a given event will be discussed at the
Drivers’ briefing.

While the R.R.M.V. is in motion on the race circuit, it is forbidden for a
contestant to pass the R.R.M.V. unless he/she is waved by specifically.

Only a Driver may perform work on an automobile within the first line of
protection on the circuit. It is not permitted for the crew or any other person to
render physical assistance in performing such work. Marshals or other officials
may push or tow a disabled car to a safe location without penalty. It is not
permitted for a Driver to push his/her car except in the pits.


Crew members shall wear clean uniforms or other appropriate and safe attire
at all times during practice, qualifying and the race in order to present the best
possible appearance to the public. Tank tops, shorts and similar attire will not
be permitted. Whenever Prototypes and/or GT cars are being refueled in pit
lane during practice, the refueler must wear fire-resistant clothing, including
gloves and balaclava or helmet with face shield and goggles. During a race, if
the race is of a length such that refueling is anticipated, crew members,
industry support people and all other individuals over the pit wall must wear full
fire-resistant clothing on their exterior. Industry support people must be clearly
identified as non-Team members.

All fueling in the pit lane during a race must be done using IMSA approved
gravity fed fueling rigs. Refer to the Supplementary Regulations for the
individual series for specific refueling regulations.

6.5.3 OTHER EQUIPMENT General: Compressed air tanks, air lines, hoses, fuel barrels, refueling
equipment, tools, spare parts, spare body panels and any other equipment or
materials stored in the pits must be situated behind the pit wall and may not
block or infringe upon fire lanes or other designated safety zones. Carts: Motorized carts and similar 3- or 4-wheeled vehicles may not be driven
into pit lane. Use of such vehicles in the paddock/garage areas must be for
legitimate purposes only. Excessive speeds in these areas will not be
tolerated. Participants may be required to abide by state regulations regarding
the licensing and use of these vehicles. Such vehicles may be prohibited at
certain events by local ordinance. Air Tanks: Air tanks must be securely fastened or anchored once their
protective caps are removed. A protective cage or guard around the
regulators and fittings must be in place at all times. Sparks: No electric-driven tools or other equipment which may generate
sparks are permitted in the pits. Face Masks: It is recommended that crew members changing tires wear
protective face masks to prevent inhalation of certain materials. All structures or fixtures extending over pit lane must be at least 6’ 7” above
the road surface.

6.5.4 PIT LANE REGULATIONS A maximum of two (2) people per car will be permitted at the wall which
separates pit lane from the track depending on the layout and track
regulations. The Race director may further limit this number. Crossing pit lane
must be done under a pit marshal’s supervision during a race and should be
kept to a minimum at all other times. Just before the start of the race, until all
cars have passed the pits on the first green flag lap, no one except authorized
Officials and fire marshals may be at the signaling wall. During a race one (1) person may go over the pit wall just prior to a scheduled
pit stop to signal the race car to its pit. This person may talk to the Driver or
crew members, but is not allowed to perform any other function. All other
Team members and all equipment must remain behind the wall until the car
has come to a stop in its designated pit. At that time a total of five (5) Team
members are permitted over the pit wall to perform service on the car. Not
counted in this total are:

a. A Driver seated in the car.

b. A Driver entering or leaving the car.

c. Industry representatives examining a car’s equipment, tires or other

d. The Team member manning a fire extinguisher.
All other Team members over the wall will be considered working on the car,
as will a Driver if he/she performs any work on the car. Whenever a Team member is working under a car in pit lane, jack stands or
safety supports must be in place under the automobile. Before leaving its assigned pit box, the race car must be completely free of all hoses,
tools, etc. At no time may a car be driven over its own air line, tool or part. Lines,
tools, parts, wheels, etc. must not be allowed to encroach upon, roll into, or otherwise
be propelled into the fast pit lane or adjacent pits. This regulation may be modified in
certain pit configurations. At the conclusion of the pit stop, Team members should
promptly carry all equipment back behind the pit wall. During official practice and qualifying sessions, these same regulations are in
effect except that the Team is not restricted to a total of five Team members
performing service on the car.

6.5.5 PIT TRAFFIC It is strictly forbidden to drive a car in reverse or against traffic under its own
power in pit lane. A Driver who overshoots his/her assigned pit must either
complete another lap or he/she may be pushed by his/her crew to his/her pit in
reverse direction. A car may be pushed in the pits by its Driver, its crew or by officials.

Cars may be removed from the pits during a race only with the approval of the
Race Director. The Race Director may assign a marshal to observe the work

All automobiles must be gridded at a time designated in the Supplementary
Regulations. Any automobile arriving after the published time may, at the
discretion of the Race Director, be placed on the back of the grid; it must not
attempt to regain its original starting position. The running of engines during
pre-race ceremonies will not be permitted.

These procedures will be used when IMSA classifies a race as an oval race on
Any yellow light or flag displayed is to be considered a full course yellow.

a. During Practice or Qualifying: As soon as a yellow light/flag is observed, all
Drivers must reduce speed and enter the pits as soon as possible.

b. During a Race: As soon as the yellow flag or light is observed, speeds must
be reduced with the leader slowing the field gradually in anticipation of the
safety car entering the circuit. OVAL TRACK RACE START
On the final pace lap, the pace car will turn off its lights in Turn 2 and
accelerate from the field. The pole car brings the field gradually up to speed
Safety car will extinguish its lights and exit the circuit. Leader will gradually
bring the field back up to speed in anticipation of a restart. When the green
flag is displayed, all yellows will be immediately withdrawn and racing may

then be conducted in any manner deemed appropriate by the Race Director. There
shall be no fee payable for such informal inquiry.

9.5.2 If the informal inquiry does not resolve the dispute, the time limitation for filing a formal
protest shall commence as soon as the informal inquiry is terminated, or as otherwise
provided in Article 9.2.1.

publisher, to publish any decision, penalty or judgment imposed by IMSA, the Race
Director, Stewards or the Board, including publication of the names of the involved


IMSA will publish rules and specifications for various classes of cars eligible to

The automobile or car shall be defined throughout the IMSA CODE as consisting of
the bodyshell/chassis unit, and the IMSA approved engine block or crankcase, neither
of which may be replaced during a race. In the case of rotary engines the cylinder
block shall consist of the front, intermediate and rear housings. It must have at least
four wheels not in a line, two of which must effect the steering and two that effect the

11.2 TIRES

11.2.1 IMSA will regulate the eligibility of tires in its sanctioned competitions in order that no
competitor shall have any tire advantage in qualifying or a race. IMSA may require a
competitor to use the same tires as he/she used in qualifying or restrict the number of
tires used during qualifying.

11.2.2 It is prohibited to use traction compound or any substance which might alter the
physical properties of a competition tire as supplied by its manufacturer.

11.2.3 Tire warmers and any other means of artificially warming tires are prohibited.

11.3 FUEL

11.3.1 IMSA reserves the right to have all cars use the same brand and designated grades
of gasoline in a given event. When this right is exercised, it will be stated in the event
Supplementary Regulations or in other IMSA bulletins for that event. Fuel used for
practice, qualifying and the race will be supplied by the “Official Fuel” supplier and
must be used exactly as supplied by the “Official Fuel” supplier. An approved
lubricant may be added to the fuel for some engine types with the prior approval of

11.3.2 In the case of any event where an “Official Fuel” has been named, IMSA may sample
the actual fuel(s) provided by the fuel supplier and those samples will become the
benchmark from which all competitors’ samples will be judged. IMSA reserves the
right to check any fuel at any time during a competition.

11.3.3 Competitors are responsible for the proper handling, transportation and security of
their fuel from the time it is dispensed to them and for the proper disposal of unused
fuel and/or fuel drums afterwards.

11.3.4 Competitors are specifically requested not to leave any fuel at the circuit after the


11.4.1 The official fuel supplier will establish an ecologically-sound disbursement area at
each IMSA event. All fuel will arrive in a special series tank truck. Fuel can be
dispensed in any quantity into 55 gallon drums or directly into the race car
(contestants may need an adapter for fuel cells). A maximum allotment per Team
may be established to avoid shortfalls.

11.4.2 Payment arrangements should be made directly with the official fuel supplier.

In addition to the special series tanker, the official fuel supplier will provide technical
support in the disbursement area at each event to lend technical assistance and
answer competitors’ questions about fuel.

Each entered car must be inspected and approved by the Technical Director or
his/her delegated assistant(s) before it will be allowed to participate in competition or
practice. No expressed or implied warranty of safety shall result from this inspection or
approval. It is the responsibility of the Entrant to have his/her car free from mechanical
defects and in safe racing condition. Cars damaged or altered after they have been
approved at inspection are subject to re-inspection and approval. IMSA will make the
final decision on the safety and eligibility of an accident-damaged vehicle. Major body
components must be maintained in normal position throughout the competition.
Questionable cars are subject to approval by the Technical Director. Cars shall
present a neat, clean and professional appearance.


11.7.1 IMSA at its sole discretion, reserves the right to impound and inspect cars competing
in an event.

11.7.2 The timing, location, method and type of car inspection, and the number of vehicles to
be inspected at any event will be determined by the Technical Director.

11.7.3 It is the responsibility of the Driver or Entrant to prepare a car for inspection when
requested to do so by the Technical Director or his/her assistant(s). Any expense
incurred, except in the case of a protest, shall be the liability of the Entrant.
Preparation of a vehicle for inspection must be performed in a timely manner as
determined by the Technical Director. Any part that does not comply with the IMSA
CODE may be indefinitely retained by IMSA.

11.7.4 Admittance to any area in which inspections are being made is controlled by the
Technical Director.

11.7.5 Each car entered must submit to Technical Inspection during scheduled hours and
display an official Tech sticker.

11.7.6 Eligibility under IMSA rules:
a. Both metric and English dimensions may be given in the IMSA CODE. In such
cases, when the two systems do not equate exactly, measurements for
compliance during inspection will normally use the system most advantageous to
the Entrant.
b. The IMSA Technical Director may establish tolerances for measurements taken
during inspection; may require components on the car to fit IMSA templates; may
require IMSA monitoring devices to be fitted to a car; and/or may require IMSA
limiting devices to be fitted to a car.

11.7.7 Safety of the design and construction per inspection form.

11.7.8 Appearance: Clean and neat, no old damage.

11.7.9 Identification numbers must be placed on both sides and front, and must be legible to
the satisfaction of the Chief Timekeeper. Specific requirements may be provided in
event Supplementary Regulations.

11.7.10 Racing Tires: Mandatory, unless Supplementary Regulations provide otherwise.

11.7.11 Leakage: Not allowed.

11.7.12 Driver Safety Equipment: Per Article 5.14.

11.7.13 Compliance with sponsor advertising requirements.

11.7.14 Mandatory safety requirements listed below.

11.7.15 Mandatory safety modifications for all cars except as specified in the Supplementary
Regulations for a specific series. A 3" wide, six point Driver restraint system of approved design must be installed. The
effectiveness and longevity of a seat harness is directly related to the way in which
they are installed and maintained. The belts must be replaced after a severe collision
and whenever the webbing is cut, frayed or weakened due to the action of chemicals
or sunlight. They must also be replaced if any buckles are bent, deformed or rusted.
Any harness which does not function correctly must be replaced. All cars must be equipped with two master electrical circuit breakers, one accessible
from inside (accessible by the Driver when normally seated and fitted with the
mandatory safety harness), and the second outside the car, that control all electrical
power (except electrically actuated fire systems). The preferred outside location is the
passenger side cowl area. The circuit breakers must be clearly marked by a spark in a
blue triangle. All cars must have at least two operating red brake lights and two taillights. Amber
brake lights will not be permitted. (During a competition, the Race Director may accept
one functioning headlight, one functioning taillight and one functioning brake light due
to damage or equipment failure.) Headlights must be protected against breakage. Headlights may be taped. Two external rear-view mirrors must be installed. Minimum dimension of each external
mirror: 100 cm2. Safety fuel cell of an approved type meeting FIA Spec FT-3 is required, must be
mounted outside the Driver’s compartment, separated by firewalls, flame and
leakproof, and protected as far as practicable by the roll cage. Steel or steel braided
fuel lines with appropriate fittings, fuel cell check valve, and vent line check valve are
mandatory. The fuel cell vent system on the car must be designed so that all fuel
vapors released during refueling are returned to the overhead tank via the 2" ID
refueling vent hose. NO SPILLAGE WILL BE TOLERATED! Refueling equipment
protruding into the Driver’s compartment must be shielded so as to prevent hazard to
the Driver in the event of rupture. Dry break fuel fillers and vents are required on all
“LM”P/”LM”GTP and “LM”GT cars. They must be located away from the engine
compartment and exhaust. The bodywork may be modified to install fillers and vents
so they do not protrude beyond the plane of the outside mounting surface. All fuel
cells less than 20 cm from the lateral flanks must be protected by an adequate
crushable structure. Hoods, deck lids and movable body sections must be secured with supplemental pins
or fasteners. Latches may be deactivated. On cars where a key is required to open
the trunk lid, the lock must be deactivated or may be removed. Supplemental pins used to secure movable body sections (such as hoods, doors,
fenders, lids and removable tops) must have attaching cables to prevent accidental
loss of pin. No concealed pressure type containers, feed lines or actuating mechanisms are
permitted, even if inoperable. Full roll cages of approved design are mandatory. Material and construction
specifications and recommended designs are contained in FIA Sporting CODE,
Appendix J, Article 253, Section 8 and in these rules.
a. Competitor must be prepared to drill inspection hole(s) in the roll structure for
b. See the technical regulations for “LM”P/”LM”GTP and “LM”GT material and
dimension requirements. A fire extinguisher of the following type and size is required for the respective
categories and must be carried and in certified working order at all times. All
“LM”P/”LM”GTP and “LM”GT cars must have an on-board fire extinguisher system
with an approved extinguishing material that is in accordance with the FIA Sporting
CODE, Appendix J, Article 258.14.1. Trigger must be marked with a red circle with the
letter "E" and be operable by the Driver and also from outside the car. Outlets must be
directed into the Driver, engine and fuel compartments. All cars must be fitted with one front and one rear towing eye, painted red, accessible
without the use of tools. They must be securely fitted to the chassis of the car by
means of a metallic rigid element (cable loops are forbidden). They must be strong
enough to allow recovery of a car lying on its flat bottom in a gravel bed. Should the
towing eye break, the track marshals will pull the car to a safe position using any
element of the chassis or of the bodywork whatsoever, which they consider strong
enough, and the car may be excluded from the race. In the event that a car is
damaged as a result of these actions, IMSA will accept no responsibility for any
damage caused, however it may have been caused. In all cases, the Driver must be able to easily exit the car through both the Driver side
and the passenger side in an emergency. An on-board starter and energy source must remain functional at all times, except
when deactivated in an emergency by the master electrical circuit breaker
(Article During periods of darkness, up to three (3) identification lights are permitted on the
top or on the side, provided they do not face rearwards, flash or blink. They may not
be yellow, blue or excessively bright red, and all identification lights are subject to
approval by IMSA. All cars must conform to current IMSA regulations for sound enforcement regulations.
These regulations may be superceded by local ordinances. An "arrow" decal denoting tow hook location, window net release and door release
must be affixed in each of these locations. Evaporative-loss Freon cool-suits are not permitted.

11.8 If the Technical Director determines prior to the race that a car does not meet the
applicable specifications, the car will not be allowed to compete unless, in the
discretion of the Technical Director, the deficiency

a. Will not affect safety;
b. Cannot be corrected in time for qualifying or the race (if no qualifying);
c. Will not provide the competitor a significant competitive advantage over other
competitors; and
d. Is so insubstantial as not to warrant a determination that the car is ineligible to
If the Race Director permits the car to compete under these circumstances, the
Technical Director will apprise the competitor in writing of the deficiency, and the car
will be prohibited from competing in any future events if the deficiency has not been

11.9 On an individual basis, IMSA may approve equipment to be fitted to race cars and/or
Drivers or waive certain procedural requirements for the sole purpose of enhancing
the television coverage of the event.
