The big change: the lead-in light will be changed from red to yellow, following suit with yellow caution flags and yellow caution lights: jumping and passing is allowed, but use caution while doing so.

AMA Supercross Race Procedure Update

Following the recent events at Round 7 of the AMA Supercross Championship in Arlington, Race Direction recognizes the need for clear communication and consistent visual signaling on the racetrack. Effective immediately, the following procedural updates are in effect:

Lead-In Light Update

The single red lead-in light (formerly known as the “pre-light”) that gave advance notice before the red lights will now be changed from red to yellow.

Going forward, it will be referred to as the Yellow Lead-In Caution Light.

This change aligns all on-track caution indicators under a consistent yellow designation:

• Yellow Caution Flags
• Yellow Caution Lights
• Yellow Lead-In Caution Light

Meaning of Yellow Signals

Yellow flags and lights indicate a potentially hazardous situation on or near the racetrack. Riders must exercise caution. Jumping and passing is allowed.

Red Lights and Red Cross Flag – No Rule Change

There are no changes to the current rulebook regarding Red Lights or the Red Cross Flag.

Red Lights and the Red Cross Flag:

• Indicates a significant safety concern and takes precedence over all other flags.
• Riders must follow all directions given by race officials.
• Passing is prohibited.
• Riders must traverse all obstacles individually, absolutely NO double, triple, step on/off, etc.
• Riders must exercise extreme caution and not race or accelerate in an unsafe manner.

Race Direction remains committed to improving clarity, consistency, and athlete safety through enhanced procedures and communication.
