Unlimited Off-Road Racing Course Marking Guide
Speed Zones: Race speed in all pits is 25 mph.
GPS File Markings vs. Ground Course Markings:
Course markings on the ground always take priority over what is provided on the GPS file, both in pits and on the entire race course.
Stop Checks:
Stop Checks entering the pit are noted as “STOP CHECK, 25MPH SZ BEGINS” on the GPS file. All vehicles must come to a complete stop before entering the 25mph speedzones. Please use caution, as we will have course workers in that exact location.
Resume Race Speed:
When it is approved to resume race speed, it is noted as “25MPH SZ ENDS” on the GPS file. All vehicles may resume race speed when passing through the resume race speed signs.

Caution Marker (Yellow)
Single Caution Ahead signs will be used to alert drivers to potential hazards that are not an immediate danger but still require extra driver awareness. Generally speaking, cautions will be placed in areas in which you do not need to slow down, but need to be prepared to do so if necessary. Some examples include road crossings and speed zones.
- First Marking – Single Caution Ahead Sign, at approximately 150ft before the caution.
Moderate Danger (Pink)
Danger signs will be used to mark hazards that may cause moderate damage to race vehicles. Generally speaking, dangers will be placed in locations where you may need to slow down. Some examples include blind turns, drop-offs, and moderate g-outs.
- First Marking – Single Danger Ahead Sign, at approximately 150ft before the danger.
- Second Marking – Single Arrow, within 50ft of the location of the danger. Dangers will be marked on BOTH sides of the course wherever possible.
Extreme Dangers (Pink)
Extra markings will be used to mark the most significant hazards that are likely to cause heavy to extreme damage to race vehicles. These will be marked with progressive signage to provide multiple warnings prior to the danger. Some examples include high speed 90 degree turns, large g-outs, and dangerous cliffs/drop offs.
- First Marking – Single Danger Ahead Sign, at approximating 300-350ft before the danger.
