American Rock
Crawlers Association Rules & Regulations 2001 Course Rules
Point System The following is a list of point assignments for
competition in all ARCA events: Stopping 1 point
One point will be issued after a competitor's vehicle has stopped
forward progress for four (4) seconds. Stopping is defined as a
vehicle not making forward progress. A team whose vehicle's tires
are rotating, but the vehicle is making no progress, is considered
stopped and will be marked as such. Once stopped, the competing
team will receive no further calls until forward or backward
progress is made. Backing 1 point
One point is issued for a purposeful reversal by a competitor. A
purposeful backup is considered when a driver puts the vehicle in
reverse and backs, pushes in the clutch and rolls back, etc. A back
is not counted when the vehicle is nudged back by the obstacle.
Reversals are counted only when the vehicle moves backward.
A
reverse in an attempt to save a rollover is considered a back and
will receive backing points. If a competitor has stopped (after the
full four seconds) he receives his points for the stop. If he then
chooses to reverse he will receive the point for the reverse. If a
competitor reverses prior to the four-second stop rule, he will
receive only one point for the back. Gates
Each obstacle is marked with gates or flags. The gates include the
start gate, course gates, trees and bushes that are tagged with
yellow ribbon, and the ending gate.
Ten (10) points will be issued for every gate touched. The gate
does not have to fall to be counted. It only needs to be touched by
any part of the vehicle. This does not include the base holding the
gate.
Exhaust, wind, bases that fall over due to unstable rocks that have
been touched by the vehicle will not count as a touched gate.
Spotters, winch cables, pull straps, etc., will count if a gate is
touched.
Once a gate is touched it is considered disqualified from that
obstacle for the team who touched it and may not be counted for a
second contact. Gates are designed to lay out the course; however,
a competitor may exit a gate and return through the same gate
without points or obstacle disqualification in areas designated and
advised by the official.
It is the responsibility of the competing team to ask a judge prior
to any attempt to leave a laid out course. If a vehicle tire is on
the outside of a gate (outside of the course layout), a gate
penalty will be issued. From time to time, brush or trees will be
marked with yellow ribbon. Hitting the tree or brush thus marked
counts as a gate. As in the course gate, the team has only to touch
it to receive points. Tools
Vehicles must pass through an obstacle under the power of the
vehicle and spotter. Tools may be used with a ten (10)-point tool
penalty. Tools are considered any item used as a means of leverage
or bridge building that is brought with the competitor and not
found naturally in the area surrounding the obstacle. Rocks may not
be carried in a vehicle. Spotters may, and are requested to use
straps on the vehicle to aid in spotter leverage without
endangerment and will not be assessed tool infraction for such use.
Pullies or any torque/leverage multipliers for spotters are counted
as tools. Tools used to clean the course are considered a penalty.
Winches
Winching is assessed a thirty point (30) point penalty for use.
Winching is considered when a team hooks a winch cable/rope to any
anchor and begins to load the cable. A loaded cable is considered
as soon as the cable has tension on it. As an example only, a cable
that is off the ground but sagging has tension on it. However, ARCA
recognizes that all pulls are not straight and, therefore, does not
consider that a cable must be off the ground to be counted. A
separate call is issued each time a cable is attached and loaded on
an anchor point.
Therefore, two anchor points on one obstacle will
count as two winches. There are occasions where a judge or marshal
may allow a cable to be attached to an anchor for safety and no
points will be issued as long as the winch is not used to pull the
vehicle. This is called a safety cable. Breakdown Time
Each competitor is allowed forty-five (45) minutes of cumulative
breakdown time per day of competition. If a breakdown occurs, the
team may use the time left on the obstacle to begin repairs. The
team must, however, immediately move the vehicle off of the course
when they have timed out (see timing out below). Repairs and work
done while on the obstacle clock must be performed entirely by the
team (Driver and Spotter).
Outside help will immediately time out
the team and the vehicle must be moved. Once moved (either after
timing out or before), the competitor must advise the Judge of the
obstacle that he broke on that he is using his breakdown time. The
judge will mark the competitor's scorecard with the time of day and
sign it. When the repair is completed the team must tell the SAME
judge of the completion. The Judge will then mark down the time,
sign it, and mark down the number of the vehicle the competitor is
following. The team does not have to use breakdown time if they
feel they can make the repair prior to the time they are required
to be on the next obstacle.
Teams who move to an obstacle out of
order and without a judge's signature will be disqualified for that
day and receive fifty (50) points for the remaining obstacles.
Safety
The Judge has the right, but not the responsibility, to advise
spotters and drivers of unsafe acts. Further, any act deemed unsafe
by a judge is to immediately be discontinued. Failure to comply can
result in an immediate point out and the team will be asked to move
to the next obstacle. Safety requirements include, but are not
limited to, the proper use of seat belts, winch covers, controlling
spilling fluids, loose articles in the vehicle, etc.
Judges
ARCA Judges have the final say in all cases save for a
misunderstanding of the rule. The ARCA recognizes that there will
be, from time to time, errors in a Judge's calls as there are in
all sports. ARCA Marshals can overturn a Judge's decision in cases
of misunderstanding of rules. This is the case whether the points
are given to a team or taken away. Treatment of Judges, spectators
and volunteers falls under sportsmanship. Sportsmanship
An ARCA event begins the morning of sign in and continues
throughout the days until the morning after the final day of
competition. During this time, proper sportsmanship is required. If
a competitor or team member (including backup help) promotes
un-sportsmanlike conduct, is rude or abrasive to local authorities,
destroys property, displays drunken or disrespectful behavior, they
may be disqualified from the current event or future events or
both. The ARCA's goal is to promote a respectable sport and promote
sponsoring companies in a professional light. Therefore,
un-sportsmanlike conduct will not be tolerated. Purse

percentages:
- POSITION %
