Road Safety Reminder for the week of July 20 - 26, 2026

Traffic Signal Lights (Flashing/Not Working)

Flashing Red light is the same as a “STOP” sign. Come to a complete stop at the intersection before proceeding.

Flashing Yellow light means "SLOW DOWN" and proceed with caution. Slow down and be alert before entering the intersection. Yield to any pedestrians, bicyclists, or vehi-cles in the intersection. You do not need to stop for a flashing yellow traffic signal light.

Traffic Signal Light Not Working (Blackout) When the traffic signal lights are not working properly, whether flashing red or no lights are showing, treat the intersection as if it is controlled by a “STOP” sign in all directions. This means that all traffic must come to a complete stop prior to proceeding, obeying the rules for a “STOP” sign.

According to Guam’s Traffic Violation Bureau’s (TVB) Traffic Fine Schedule
