360 SPRINT CAR RULES
ASA Membership is mandatory for all 360 Sprint Car drivers. It
is highly recommended for all crew members as well.
A. QUALIFYING
1. East Bay Raceway Park or their representative will advise
drivers of the make up of the number of heat races, main events,
field maximum size and other pertinent information at the
driver's meeting.
2. The lineup posted on the pit bulletin board when cars enter
the racing surface for any race shall be the final lineup. In
the event a car drops out of the lineup for mechanical reason,
the balance of the field shall move straight forward.
3. The start will be official only upon the starter signaling
with the green flag. In the event a pace car is used, all cars
shall take their proper position behind it. If a pace car is not
used, the pole car will set the pace, which shall be consistent
with track conditions and as required to keep the field in
formation. East Bay Raceway Park shall be empowered to
disqualify or penalize any driver violating this rule.
4. A cone will be placed on the turn four area for all double
file starts. All cars must remain in proper order until they
pass this cone. (NO PASSING BEFORE PASSING CONE.) The flagman
will throw the green flag to start the race when the front row
is in side-by-side formation and the remaining field is in good
formation. If, in the official’s judgment, the front row car or
cars are out of position, a yellow will be displayed, after the
green and a warning given to the offender. Any further violation
will result in the offender being placed a row back with the car
behind the offender being brought to the front row. Any other
car not in proper position in officials' judgment will be
penalized a minimum of two positions plus one position for each
position gained over one. It will be enforced on the next
caution period or at the end of the race.
5. On all single file starts after one lap, the restarts will
start at the discretion of the leader. The leader must start
race after passing the last sign on the outside of turn 4 and
before he reaches the cone. The leader must maintain a
reasonable pace (at least 1/3 to ½ race pace), after passing the
back gate, the leader is not to slow down at all. If the leader
fires early, maintains too slow a pace or brake checks field, he
will be subject to being penalized to rear of field.
All cars must maintain single file status until after passing
the cone in turn 4. Any car passing or up beside a car before
the cone will be subject to being penalized 2 positions for each
car passed or beside, even if you do not compete the pass.
Safest way to keep from being penalized is to stay in nose to
tail formation until after the cone.
6. Any car not running at a reasonable racing speed may be
subject to disqualification for safety reasons.
7. Any car on or near the racing surface that delays the start
or restart any race shall be penalized one lap by officials. A
work area will be designated.
8. Alternates will be taken to fill any vacancies that occur,
from first unqualified cars. No alternate for any race will be
taken after the original green flag.
FLAG PROCEDURES:
YELLOW FLAG
All cars causing yellow or stopping on a yellow will be placed
at the rear of restarting lineup. An area will be designated for
any work to be done during a yellow flag. Cars causing yellow
and remaining on racing surface that are able to restart without
service, will be placed at the rear (if multiple cars, they will
be lined up in order in which they were running prior to the
yellow flag). Cars going to work area will be placed at the rear
in the order in which they return to the track.
If a car needs a second push off after all cars have started,
except for safety reasons, he will start at the rear of that
race.
RED FLAG
ALL CARS MUST STOP AT ONCE!
All restarting lineups will be single file after one lap with
any lapped cars being placed in the lineup.
