I have read the Rulebook.
Drivers Signature:___________________________ Date:__________________
Keep copy of this Rulebook with vehicle log book. (NASA Preferably)
No pretense is made of having designed a fool proof set of rules and regulations.
The spirit and intent of the rules is going to be standard by which ProTruck racing
will be guided. Event officials are authorized to decide if any equipment change is an
attempt to beat the rules. If there is a disagreement or dispute regarding the
meaning or interpretation of the ProTruck rules, the track officials shall prevail.
IF THIS RULE BOOK DOES NOT SPECIFICALLY SAY THAT YOU CAN DO
SOMETHING, THEN YOU MUST CONSIDER THAT THE CHANGE IS ILLEGAL!
Any questions about the legality of a change must be answered by a ProTruck
official in writing and that decision is final. The trucks and engines are designed to
remain in their original form, in which they were purchased new from SpecTruck, Inc.
ProTruck reserves the right to impound any truck and remove any component from
your truck at any time. Any illegal assembly or component shall become the property
of ProTruck.
If an illegal component is found, the component or assembly will become the
property of ProTruck and the driver may be fined accordingly. No fine will exceed
$5,000 dollars. If the driver refuses to surrender an illegal component or assembly,
or to pay any fine, the driver (and possibly the truck owner) will be suspended from
ProTruck competition indefinitely.
An assembly shall be considered a component that can be removed from a truck
without disassembly, such as engine, transmission, and rear end.
Engine assembly includes: carburetor
intake manifold
oil pan
distributor
balancer
pulleys
water pump
flex plate
fuel pump

using existing mounting holes for fuel cell. Fuel cell must remain attached using

materials as existing.
If you want to make a change that is not on this list it will be considered
illegal unless approved in writing by ProTruck.
FRAMES
All frames must be purchased from SpecTruck and must remain stock. Frames may
be repaired, if damaged, so long as they remain within ProTruck specs. Specific
specifications may be obtained from ProTruck in writing.

vendor. Any engine with a broken or tampered with seal will be subject to a complete
inspection at owner’s expense. In the event that an engine should need repair, it
must be taken to an authorized ProTruck vendor, with seals intact, who is the only
one allowed to repair and re-seal a damaged engine. Or a new engine may be

valve may not be modified in any way! A fuel sample device must be in place and
accessible for technical inspection.
LICENSE
All competitors will be required to conform to ProTruck and NASA licensing
requirements to compete. If a driver is not deemed to be safe to other competitors
by the event officials, he or she may be asked to start at the rear of the field or to
withdraw from competition until the event officials feel he or she is not a safety
threat to the other drivers.

eligible for any prize or contingency money.
OFFICIAL RACE
In order for any race to be considered an official points paying race, the event must
be on the official protruck schedule, there must be at least three trucks competing
and the NASA requirements for an official race must be met. If any one of these
requirements is not met, the race will be considered non points paying.
PROTESTS
A competitor may anonymously protest any specific component on another
competitor's truck. All protests must be in writing and must be filed within 15 minutes
after the conclusion of the main event. The competitor filing the protest will be
required to pay a protest fee to ProTruck officials in cash at the time the protest is
filed. The amount of the fee will be determined by ProTruck officials based on the
specific item being protested. After the inspection, if the protest is valid, the
competitor filing the protest will have the protest fee returned in full. If the protest is
found invalid, the competitor filing the protest will forfeit the protest fee and the
competitor being protested will be compensated by ProTruck officials.
FINAL RESULTS
Results are final 30 minutes after race! If there are any questions regarding your
finishing position, you must take this up with NASA officials directly following the
race. Once the final results are posted and there are no discrepancies, those results
will be final.
SEASON POINTS
All drivers must throw out the results of two races each season in determining the
year-end points results. The Protruck Champion will be determined by the points
leader after the two races are dropped. Any two races can be dropped, whether any
points were earned for those races or not.
