2.10 RAIN SITUATION
The Race Director will stop the racing if it rains. If there are delays due to weather, re-arrangements will be made as follows:
2.10.1 In case of the interruption of a heat, the entire heat will be re-run.
2.10.2 In the event of rain, the track must return to 100% dry conditions before racing can re-commence. The 100% dry conditions will be determined by a majority decision of the International Jury.
2.10.3 If a round of heats is started, it must be completed under the same conditions. If a round is halted due to rain or unforeseen circumstances and cannot be completed, this round will not be counted until the remaining heats in the round can be completed.
2.10.4 If weather and time permit and there is no time restriction on track use, every endeavour should be made by the Race Director to run as many of the maximum six (6) rounds of heats as possible.
2.10.5 A minimum of two (2) of the total of six (6) rounds must be completed.
CHRISTMAS TREE FINALS
2.10.6 In the event of rain during the 1/4 finals, if 50% of the race has been run before the rain, the race is declared. If rain falls before 50% of the race has been run, the results will be kept from the moment of stopping which will be the previous lap when the leading car crosses the finishing line. The new start will be given for the time which remains to complete the final. The two results will be added to give the final and definite placings. If the second start cannot be given for any reason, the results from the first part will be used as the final and definite placings.
2.10.7 In the semi-finals, if 75% of the race has been run before rain commences, the race is declared. If rain falls in the first 25% of the race, a total re-run will take place. If rain falls between the 25% and 75% mark, the total of the two (2) combined legs will be added together.
2.10.8 In the event of a semi-final being interrupted in this way, the top three (3) from each semi-final will advance to the final.
2.10.9 In the event of rain falling before the 25% mark where a complete re-start is required, drivers will be allowed to undertake maintenance on their cars.
2.10.10 If 75% of a main final has been run before rain commences, the race is declared. In the event of a main final being interrupted by rain where the two results will be added together (i.e. after the 25% mark), drivers may make repairs, re-fuel and change tyres before the re-commencement of that main final.

Transmitters will be furnished to each competitor after completion of technical inspection and prior to their heat. All transmitters must be returned to impound following their heat. Transmitters in the pit area, or areas other than the drivers' stand and impound, during official competition hours, will cause disqualification.
2.14.2 TRANSMITTER INSPECTION
All transmitters must be tested and inspected prior to their use. A spectrum analyser will be used for radio inspection. All transmitters passing inspection will be identified and only these transmitters, thus identified, may be used in the event.
2.15 LAP COUNTING AND TIMING
counting, with cumulative and split lap times, will be in place for each car.
Competitors are required to install
a small transponder into their cars according to the organiser's instructions.
An audio/video tape recording will be made.
Every competitor is also allowed to use his own IFMAR approved personal transponder if the lap counting officials are informed and agree.
If an organiser is using a personal transponder system, he has to provide to all participants, not having their own transponder, a transponder for every heat or final free of charge. It is strictly forbidden to ask for a rental fee. A deposit of the replacement value for the personal transponder may be demanded. If a competitor for any reason destroys or does not return a personal or normal transponder, he loses his deposit.
The driver has to ensure that his personal private transponder belongs to the marked chassis.
Significant stops (refuelling, tyre changes, crashes, etc.) will be noted with times of stop and restart. This record might not include every incident, however, its intent is to verify incidents, whenever possible.
AMB lap counting system or IFMAR approved equivalent must be used in duplicate. A suitable working computer with proper race proven programmes must be provided to sort lap times, print results from heats and sort final positions from each round of heats within l5 minutes of the completion of the round of heats. Chronometers must give time to 1/100th of a second, in all cases, the hundreds will be utilised. In the case of equal results, the following best heat will separate the competitors. If both the primary and support lap counting systems fail during a qualifying heat or final, the heat or final will be re-run as soon as is practicable. Under no circumstances will any lap score or time, other than those from the official time keeping equipment, be accepted for any purpose to do with the running of an IFMAR race.
2.16 DISPLAY AND DISTRIBUTION OF THE RESULTS
The display of the positions in a specific heat or final will be done in the pits and in the Team Managers'/Press stand. At the end of each heat (every l5 minutes) or of the finals, a copy of each competitor's lap sheet will be available for checking and information. Copies of the time-lap sheets of all cars of the heat or the final will be displayed with the result. At the end of each round, results of the general classification will be available.

SUB-FINALS AND FINALS
SUB-FINALS AND FINALS
4.2.4 An audible warning will be given in English language at one (1) minute and at thirty (30) seconds.
4.2.5 From thirty (30) seconds until three (3) seconds the cars may be placed in the starting boxes. If a car is not in the starting box at the three (3) second mark, it must start from the pitlane after all cars have started officially.
4.2.6 From ten (10) seconds until three (3) seconds, time is counted down in English language, second by second.
4.2.7 At five (5) seconds, the starter will lower the starting flag and at three (3) seconds, the flag will be down, touching the ground. At this time, cars must be released by the mechanics who will all step back behind the hold line. The cars must remain in the boxes, no part of the car touching the starting line.
4.2.8 From 3 seconds, the counting stops and the start signal will be given by the starter between 0 and 5 seconds. If the grid is not to the satisfaction of the starter, he may command a re-start, beginning count down from 30 seconds.
4.2.9 The official starting signal will be audible by means of a horn operated by the starter. This signal will also start the timing systems.
4.2.10 Early starts - ALL FINALS ONLY.
Early starts, i.e. any car touching or crossing the starting line, will be penalised with a stop and go penalty. The duration of this stop and go penalty has a to be determined at the Team Managers’ Meeting and depends on the lap times. This penalty is issued by the starting official or the time-keeping official and has to be announced immediately after the start. The penalty will be marked on the result sheet.
4.2.11 Under no circumstances will the race be stopped due to a jumped start.
4.2.12 Only the Race Director may interrupt the race and order a restart in the event that he considers the starting procedures or the start were not carried out correctly.
4.2.13 DELAYED START - As long as the starter has not called the cars to the starting line, every participant of the semi- finals and the final may request a delay of ten (10) minutes for repairs on his car. The delay will be granted only once for each semi-final and final. The track shall be closed to all cars during the delay period. The driver requesting the delay for whatever reason, except an error in frequencies by Race Control, must start from the back of the grid, six (6) metres/19.68 feet behind the last official grid position.
Marshals will be provided for all racing. No other person is allowed on the track when racing is in progress. If a car stops on the track, it will be returned to the pit area by a marshal. A penalty will be given for any violation of this rule. All marshals must wear closed shoes.
Only vehicles which conform to all regulations will be accepted for racing. Technical inspection will be done on Sunday and Monday. The cars will be examined and, if the car conforms to the rules, the chassis will be marked. At any time, the Race Director may ask the competitors to present their cars to the Technical Inspector. Random inspection will occur on the start line for numbers, tyres, wings and chassis.
No race will be delayed because of non-compliance by a competitor. At the completion of each heat all cars in that heat, whether they finished or not, must be presented for technical inspection. Cars which are not presented for technical inspection at the end of a heat will be disqualified from that heat. Any race damage will be taken into account. At the end of finals, all cars will be impounded and may be inspected for engine size, fuel tank capacity, etc. Any infringement concerning engine, fuel tank and weight will cause disqualification from a driver's best existing qualifying heat or a final. For the first infringement, the disqualified driver’s position will be shown as the last position in that heat or final.
A second infringement concerning any one of engine, fuel tank or weight, will cause total and immediate disqualification from the entire event. The disqualified driver will be placed on the last position of the final qualifying results and/or the last position of the final positions’ results and he will be noted as a disqualification. Any infringement, other than those concerning engine, fuel tank and weight, will cause disqualification from that heat or final and the disqualified driver’s position will be shown as the last position in that heat or final. All cars must be fitted with a clutch, a braking system and an exhaust pipe that conforms to the rules.
The engine and fuel tank may be checked at any time. The volume of the fuel tank will include all fuel piping and filters up to the carburettor. Following method of measurement will be used:
- pinch off pressure lines, - fill the fuel tank completely, - remove fuel pipe from the carburettor inlet, - connect a calibrated syringe to the fuel line which has been disconnected from the carburettor and pull all the fuel into the syringe. The amount of fuel removed by the syringe will be considered as the total content of the fuel system.
4.4.1 Only one car per driver will be accepted.
4.4.2 The chassis plate of each car will be marked with the competitor's number.
4.4.3 Only one chassis may be used for all qualifying heats and finals. The only exception to this rule will be in the case of a broken or bent chassis which may be changed with the Race Director's approval. The new chassis must be presented to technical inspection for marking before re-building the car.
In the case of two drivers using the same frequency and qualifying for the same final, the higher placed driver may keep his frequency and the lower placed driver must change. The time allowed for frequency change will be ten (10) minutes. The lower placed driver who cannot or will not change his frequency may not take part in the final for which he qualified. If a driver must change his frequency before the start of a semi-final or a final, due to an organiser's error, he will be allowed (ten) 10 minutes. If a driver finds his radio defective or has made an error in the selection of his frequency at the start of a final, the race will not be delayed. For the entire duration of the event, the frequencies in use by all drivers will be known only by the Race Director and each individual driver. All frequency changes must be authorised by the Race Director before the change is made. The organiser shall not display any driver's transmitter frequency on any heat sheets, result sheet or race schedule to preserve the security of the frequency control systems. Each driver in the main final shall be permitted to change his frequency before the start of the race. Only the Race Director is permitted to know the frequency used by the main finalists.
4.6 CAR NUMBERS AND LAP COUNTING TRANSPONDERS
Only the numbers supplied by the organiser will be used on the cars. Each participant is responsible for attaching the lap counting transponder to his car. During qualifying, any car starting without a lap counting transponder will not be counted. If a lap counting transponder fails or falls off during the heats, the vehicle will be timed and counted manually, if possible. In this case, the Race Director will verify the results and his decision will be final. During the final, any car without a lap counting transponder will be counted manually by a manual back-up system. Under no circumstances will a heat or a final be re-run due to a car not having a lap counting transponder or failure of the same. This also applies to a car not having the correct numbers and placement of these numbers.
Start - green flag or national flag.
Finish - chequered flag for final only.
Blue - The car which is blue flagged must allow the car behind him to pass.
Yellow - Danger on the track - slow down.
Black & white - Official warning to the car which is flagged (diagonal).
Black - The car in question must stop immediately in the pits.
Green - Track open.
Red - Track closed. All cars must stop immediately.
The black and white diagonal and the blue flags are recommended but are not compulsory. All flags are under the direction of the Race Director who can delegate and authorise their use.
4.7.1 USE OF THE BLACK FLAG
Drivers who impede the progress of other participants
Participants driving in a manner deemed to be dangerous by the Race Director
Cars judged by the Race Director to be in an undriveable or dangerous condition. These cars, after the repairs have been carried out, may be allowed to resume.
Cars which lose their bodies or silencers must immediately stop and carry out the necessary repairs after which they may restart.
Cars which have been black flagged may re-enter only with permission from a Race Official.

The Team Manager will show to the Race Director the time-lap sheet in question (the one given or displayed by the organiser) and will indicate where he thinks an error has been made. The Race Director will resolve the problem by checking with the second lap counter and, if necessary, with the manual record of stops. The audio/video tape may be used as a last resort, if necessary, for the final result. If the request is justified, the result will be modified immediately and the Race Director will advise the Team Manager, in writing, of the result. After checking, if the Team Manager persists with his request, he will have to present a written protest within ten (10) minutes, including a $50 U.S. deposit.
4.9 PENALTIES AND SANCTIONS
During finals, participants will be allowed to change the bodies of the car with the authorisation of the Race Director, providing the bodies are of the same type and painted in the same colour scheme. In the event of a different body being fitted to the car, the Race Director must give his permission before the participant re-enters the race. Any illegal modification or change made to the car which is found during the technical inspection at the end of the race will automatically entail disqualification of the participant.
EXCEPTIONS:- Tolerances allowed in technical inspection for fuel tanks. Any damage incurred during a heat or final will not entail a forced stop or disqualification of the participant except in the following cases:
- loss of a body (the spoiler does not count as part of the body).
- loss of the silencer or its ability to silence the engine.
- a car which becomes dangerous or undriveable.
- The car in question may re-start after the repairs have been effected.
Any car which, by the fault of another driver, is damaged or obstructed during a heat or final cannot, under any circumstances, be allowed to re-run in another heat. All participants must strictly observe the instructions given by the Race Director, Jury and Referees. The bad sportsmanship and behaviour of any competitor, even outside the official race meeting, which could injure the image and promotion of the sport, may become the object of an official, national or international sanction.
4.10 OFFICIAL ANNOUNCEMENTS
All official announcements concerning the race must be made in the English language in the pit area, drivers' stand and mechanics' area.
4.11 OFFICIALS - REFEREES
4.11.1 One IFMAR Referee will be appointed by IFMAR. Approved travel and accommodation expenses will be paid for by IFMAR, EFRA, ROAR, FEMCA and FAMAR equally. The IFMAR Referee will be supported by two (2) appointed deputy referees, one nominated and paid for by the host Bloc and one nominated and paid for by the host country’s association (see General Rule 1.12). They must be experienced and unbiased people with a good knowledge of the English language and the current IFMAR rules and will have acted as a referee at least on national level before.
4.11.2 The main task of the Referees is to observe the racing and, in particular, the good sportsmanship during the racing. They will ensure that the current rules are observed by everyone.
4.11.3 Referees may be called for information by the International Jury when a meeting is called by the Race Director.
Referees must be provided with an area from where all parts of the track,
the drivers’ rostrum and refuelling area can be
observed. The place must be separated from the drivers’ area to ensure a quiet and undisturbed working area. Protection (walls, roof, etc.) must be given against all weather conditions. The place must be equipped with a minimum of three (3) chairs, a table and a monitor connected to the lapcounting system to show the race order. There must be a separate communication system with a microphone and speakers direct to the drivers’ rostrum and the pitlane to enable Referees’ instructions to be heard only by the drivers and the mechanics in the pitlane. N.B. This system is to be totally separate from any public address system used for announcements. The organiser is responsible for providing the Referees with lunch, refreshments and a ticket to the Awards’ Banquet.
