Rules Disclaimer and Release:
The following rules are designed to establish certain minimum accepted requirements for, and the orderly management of, WILROC sanctioned events. They are intended to be followed by all racing teams (including owners, drivers and pit crew members) participating in WILROC racing events, but WILROC reserves the right to interpret, change or modify the rules at any time.
WILROC officials (including board members, committee members and race day officials) are empowered to make the necessary changes, modifications and interpretations of the rules at their sole discretion and their decision is final and cannot be challenged, except as outlined in the rules below.
All participants in WILROC sanctioned events understand that racing is a dangerous sport. By participating, each person agrees to follow the WILROC rules, accepts the risk inherent in sprint car racing, accepts that the rules in no way guarantee the safety of any participant and agrees to release WILROC from any liability for injuries or damages.
Racing teams are solely responsible for the design, construction, fabrication and maintenance of their sprint cars and related equipment, as well as safety equipment (including seat belts, head and neck restraints, arm restraints, safety netting, helmets, racing suits and shoes) used in the sprint car or worn by the driver and pit crew members. WILROC rules must be followed, but it is the responsibility of all participants to ensure that their sprint car, driver and crew are safe.
WILROC is not responsible for any damage or injury to equipment or participants at any WILROC sanctioned event.
THERE IS NO EXPRESS OR IMPLIED WARRANTY OF SAFETY FROM THE WILROC RULES, COMPLIANCE THEREWITH, OR PARTICIPATION IN WILROC SANCTIONED EVENTS. BY PARTICIPATING, EACH PERSON ACCEPTS ALL RISKS ATTACHED TO SUCH PARTICIPATION AND RELEASES THE WILROC SPRINTCAR ASSOCIATION, ITS OFFICERS, DIRECTORS, OFFICIALS, EMPLOYEES AND AGENTS FROM ANY AND ALL LIABILITY, AND INDEMNIFIES THEM JOINTLY AND SEVERALLY FROM ANY LEGAL ACTION ARISING FROM ANY EQUIPMENT DAMAGE OR INJURY SUFFERED BY THE PARTICIPANT AT ANY WILROC SANCTIONED EVENT.
VOTING: Only one vote for representative of a car (owner or driver). Multiple car teams have only one vote. Car must have competed under the WILROC banner to have voting eligibility.
WILROC Rules shall apply at all WILROC events. Track officials and/or WILROC officials will be responsible for enforcement at all WILROC sanctioned events. At the discretion of WILROC officials in charge, any competitor may be disqualified for rule violations, hazardous equipment or unsafe actions. All race cars at a WILROC sanctioned event are subject to inspection at any time. Approval of a race car, at a WILROC sanctioned event, by WILROC official(s) shall mean only that the car is approved for participation in a competitive event and shall not be construed in any way to mean that the inspected race car is guaranteed mechanically sound.
The WILROC official(s) shall not be liable, nor shall WILROC, for any mechanical failure, and not for any losses or injuries resulting from same. Tech and safety inspections may occur at any time and are solely at the discretion of the Tech and Safety Committee members.

For our part we will make every effort to be consistent with our rules regardless of whom or what is involved. We will treat all participants with respect and expect similar treatment in return. A racer’s pit area is his castle-therefore please stay out of other racer’s pit areas, especially after an incident when you have been involved with that racer. Drivers remember that you are responsible for the actions of your crew. Any offending parties will be fined appropriately and disciplinary actions will be initiated as deemed necessary.
