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.
- Second Marking – Danger Ahead + Arrow, at approximately 150ft before the danger.
- Third Marking – Double Arrow, within 50ft of the location of the danger. Dangers will be marked on BOTH sides of the course wherever possible.
