DISCLAIMER TREC’s primary interests are to enhance safety for spectators and participants as well as to promote trail racing as a major motor sport. TREC makes no representations or expressed or implied warranties that compliance with the rules as written or any addendums to those rules will guarantee against injury or death to spectators, participants, vendors and others or against damage to personal property. These rules and regulations constitute the minimum acceptable standards for competition and are intended as a guide for the conduct of the sport. The primary responsibility for the safe condition and operation of trail racing rests with the vehicle owner, driver, and navigator. Think safety first. In consideration of being permitted to participate in any event sponsored, promoted, sanctioned or directed by Trail Race Endurance Circuit (TREC), the competitor for himself/herself, his/her personal representatives, heirs and next of kin, hereby releases TREC, and their respective officers, directors, promoters, sponsors, employees, agents and volunteers (“releasees”) of all liability to the competitor, whether caused by negligent act or omission of releasees or otherwise while the competitor is for any purpose participating in such event. It is fully understood by each of the competitors that there is some inherent risk associated with this event, including damage to vehicles and to the individual. In addition, the competitor agrees to indemnify and hold harmless the releasees from any loss, liability, damage, or cost they incur due to such participation by the competitor, whether caused by releasees’ negligence or otherwise. The competitor agrees to assume full responsibility and risk for bodily injury, death, or property damage from releasees’ negligence or otherwise, while the competitor is participating in this event. Each competitor acknowledges and represents the following while competing: 1. That he or she has read the foregoing release and waiver of liability and indemnity agreement. 2. That he or she will at all times, while riding in a vehicle participating in an event, wear his or her respective seat and shoulder belts, eye protection , helmet, fire suite and protective safety gear correctly. 3. The owner/driver certifies that he or she has inspected this vehicle and that the same certifies it to be in good mechanical condition and adheres to all TREC rules. 4. The owner/driver has informed himself/herself about the event, either by prior participation or by investigation into the event. 5. The driver or any other person(s) in a vehicle participating in any TREC event may choose to cease racing at any time, therefore assuming all risk and liability, as indicated above. Although safety generally is everyone’s concern and certainly the highest priority of TREC, the final responsibility rests on the competitors. Competitors can, at any time, choose to not race or cease racing at any time or area they feel uncomfortable or unsafe driving. TREC approved Helmets must be worn at all times while driving in a competition vehicle on the course. All safety requirements and rules must be followed at all times. 2 2.1 Classes 2.1.1 TREC categorizes vehicles into the following classes: 2.1.1.1 Class A 2.1.1.1.1 Class A is intended for the most progressive four wheel drive vehicles in use today.
