The official introduction to the 2026 Ultra4 Rulebook, including its purpose, applicability, equipment standards, document conventions, governing authority and liability information.
The Ultra4 Rulebook is the sole property of, and the copyright held by, FOCUS. The Ultra4 Rulebook may not be used by any person or entity, in part or in whole, for any reason whatsoever, without the express written permission of Ultra4 and FOCUS.
This Ultra4 Rulebook is issued on the authority of FOCUS and is effective upon receipt unless otherwise directed.
The Ultra4 Rulebook is intended to provide approved standardized regulations and procedures to ensure the safest, fairest, highest quality competitive motor sports experience for competitors, fans, and sponsors of offroad motor sports events.
The Ultra4 Rulebook contains the rules, regulations, specifications, and guidelines (hereafter collectively known as the “rules”) that govern the conduct of, and participation in, Off-road motor sports competitive events.
Ultra4 or FOCUS may issue Supplementary Regulations that are in addition to the rules contained in the Ultra4 Rulebook, or that amend, suspend or modify existing rules and regulations. Supplementary Regulations apply to a specific event, race, venue, or time and place. Ultra4 may issue Special Rules to account for conditions presented by the location of the event, the condition of the course, or other circumstance. Special Rules and Supplementary Regulations will be considered official amendments or additions to the Ultra4 Rulebook when issued in writing by Ultra4 or FOCUS.
Although this rulebook is directive in nature, no instruction, however comprehensive, can apply in all conceivable circumstances. Nothing in this rulebook, therefore, is intended to replace the requirement for all participants at all times to exercise sound judgment and embody a high level of sportsmanship; nor is it intended to replace the requirement for participants to be responsible for their own safety and conduct.
All participants in any Ultra4 event must comply fully with all applicable rules as published in this rulebook and in applicable Special Rules and Supplementary Regulations.
Equipment standards and specifications set forth in this rulebook, particularly safety standards, are to be considered minimum requirements. This rulebook or any particular individual rule, specification, or standard set forth herein should not be construed as constraining teams or participants from employing greater safety mechanisms or adhering to stricter safety standards than the minimums required, providing that doing so does not cause a conflict with other rules published in this rulebook.
In the event of any inconsistency within this rulebook, Ultra4 and FOCUS shall be contacted for clarification prior to the start of an event.
In the case of a discrepancy noted, or clarification required, after the start of an event, Ultra4 will use the post-race Competition Review Board (CRB) to determine the appropriate response. Such response may include, but need not be limited to, making a ruling, issuing a clarification, taking disciplinary action, or taking some other action deemed necessary by the CRB.
In the event of conflict between any documents referenced herein and the contents of this rulebook, the latter shall prevail.
In the event of any inconsistencies between the contents of this rulebook (including any documents referred herein) and any applicable United States federal, state, or local laws and regulations, the latter shall prevail.
In the event of conflict between the contents of this rulebook and the rules or specifications of any outside sanctioning body with whom an event is co-promoted, the stricter or more stringent rule or specification shall prevail.
Ultra4 and FOCUS reserves the right to modify this rulebook together, at any time, at their combined discretion.
Ultra4 reserves the right to refuse entry to any applicant, team, competitor, entrant, participant, or any other person, to any event for any reason.
The reader of this rulebook and all participants in any Ultra4 event hereby agree to waive, release, relinquish, protect, hold harmless, indemnify and defend the promoter, track operator, Ultra4, and FOCUS, and each of their heirs, successors, officers, officials, employees, agents, contractors, and all their respective insurance companies, successors in interest, commercial and corporate sponsors, agents, employees, representatives, assignees, officers, directors, and shareholders of and from any and all claims, demands, liabilities, losses, costs, or damages or expense for any other loss or damage arising, or alleged to have arisen, from any use of any information contained in this rulebook or by reason of any inaccurate information, omission of information, or any negligent act in or related to this rulebook.
