Race
Procedure
4.15 There will free practice
on the Saturday (subject to local track operating hours) preceding Sundays
racing and where possible, practice sessions will be organised on race day
(Sunday) by the Race Director. The criteria for the duration and number of
sessions being the engine start time, number of entrants and mix of skill
factors. This under normal circumstances will be done in heat order at the
discretion of the Race Director. Sunday’s race
day will have a pre-defined timetable. I.E - drivers briefing before any engine
running, organised practice in heat order and no lunchtime practice.
4.16 Group
‘C’ or Sports Car body shells can be used for racing as long as they appear in
the BRCA approved list of body shells and conform to their respective
construction rules.
4.17 Four rounds of heats will be run
if the total number of entries is 40 or less.
4.18 The
appointed Race Director may not participate in the days racing. The Race
Director will be in control of driving standards, interference decisions,
protests, rule applications, etc and will be appointed by the club in consultation with the BRCA. If the host Club/Circuit cannot
supply a Race Director, then £1 per competitor will be deducted from the race
fees payable to the Club/Circuit, this money to be given to the Race Director
towards expenses incurred travelling to the race meeting.
4.19 All
interference claims and any protests MUST be referred to the Race Director. Any
subsequent action will be made by the Race Director whose decision will be
final. Any driver claiming interference must switch off and see the Race
Director WHILE THE RACE IS STILL IN PROGRESS. The following guide-lines will be
used by Race Directors:- To ensure continuity no
qualifying heat will be stopped unless the Race Director is satisfied that two
or more drivers have detectable interference. The Race Director will aim to
provide each competitor with ONE heat free from extraneous interference. The
Race Director will check interference possibilities with all drivers before the
start of finals and these races will not be stopped unless the Race Director is
satisfied that on site interference is occurring. A driver claiming
interference must switch off and report to the Race Director immediately. At
the discretion of the Race Director any competitor found with equipment causing
on site interference will be asked to leave the circuit.
4.20 The Race Director or
a Person who has been nominated by the Race Director will monitor driving
standards and competitor behaviour. For a first offence the Race Director will
normally impose a 10 second penalty off that heat (adjusted at the end of the
heat). For a second offence, a one lap penalty, and for a
third offence, disqualification from the meeting.
4.21 The Race Director or
a Person who has been nominated by the Race Director may impose penalties
without warning
where he considers the infringement or misbehaviour to warrant such penalty. As
a guide to drivers the following driving standards are expected:-Slower cars
are to give way to the faster cars and the driver of the slower car should call
his intention of moving off line. Deliberate collision from behind with an on line car at a corner (T-boning) will be regarded as an
unacceptable practice.
4.22 Any
driver not fulfilling his marshalling obligation will be penalised by loss of
his/her FTD. Drivers MUST arrange a competent substitute, with the Race
Directors approval, if they are unable to marshal for any reason. Unless the
Race Director considers special needs apply and except for the driver
performing scrutineering duties, marshalling obligations will be as follows:-
Drivers to marshal the heat following the one in which they race, except for
drivers from the last heat who marshal heat one. Drivers from the Open Final
will marshal the First Final to be run. Finalists
4.23 The
Race Director may request inspection of any entrants
car, at any time, to cover any or all applicable specifications. Any part of a
car may be substituted during a race except the chassis. The chassis may be
changed with the approval of the Race Director. The essence of this is that a
car cannot be replaced or substituted once entered into a days racing.
4.24 Racing will commence
at the start of the day, and no race, heat or race programme will be stopped,
or delayed, due to reasons of change in the weather, except in extreme
circumstances that it would be deemed by the Race Director too dangerous to
continue.
4.25 The
pit lane must be kept clear at all times. Re-fuelling must take place clear of
cars passing through the pit lane. Only one mechanic per
driver to be allowed in the pit lane during the race.
4.26 Frequency
pegs must be used during practice, heats and finals. Every driver must own a
peg with his/her name on it which he/she will place on the pegboard in place of
the frequency peg he/she is using.
5. Scrutineering
5.1 This
will be performed by a driver from his/her own heat. Instead of having to
marshal in the following heat, the selected driver will scrutineer the cars
from his/her own heat. His/her own car will be scrutineered by a person
selected by the race director or committee.
5.2 The
race director will use his discretion to select a suitable person from each
heat to perform the scrutineering function. A committee
member, will scrutineer first to fourth positions in each of the finals.
5.3 At the end of a heat all cars
that have taken part in that heat must be taken together with the fuel bottle
to the scrutineering area. Even if a car has been wrecked during the course of
that heat it still must be presented to the scrutineer. Failure to do this will
result in loss of FTD.
6. Start procedure for Heats
6.1 Starts to be of a staggered
nature. Order to be:-
3 Rounds - Rnd 1, 1 to
10 - Rnd 2, 4 to 10 & 1 to 3 - Rnd 3, 8 to 10 & 1 to 7.

Race Director. Cars missing the start and restarts during a race must start
from the pit lane. Note:- In order to be given a
correct finish time, a car must cross the finishing line under its own power.
