What does a flashing yellow light indicate?

A flashing yellow light indicates that drivers should proceed with caution. This signal is typically used to alert drivers to a potentially hazardous intersection or situation ahead. It serves as a warning that they need to be mindful of their surroundings and be prepared for any obstacles, pedestrians, or other vehicles that may require their attention.

In contrast to a solid yellow light, which cautions drivers to slow down as the light is about to change to red, a flashing yellow light does not instruct drivers to stop. Instead, it allows for continued movement, but with heightened awareness. This promotes safety by encouraging vigilant observation and readiness to react if necessary while still maintaining the flow of traffic.
