What does a flashing yellow light mean?

A flashing yellow light indicates that drivers should proceed with caution. This signal warns drivers that there may be a potential hazard ahead or that they are approaching an area that requires careful attention, such as a school zone or a construction area. It serves as an alert that while it is okay to continue driving, extra vigilance is necessary to ensure safety.

In contrast, a solid green light typically means you can go ahead freely, while a yellow light alone suggests that you should prepare to stop if it's safe to do so. The option about stopping and looking around does not align with the intention of a flashing yellow light, as it encourages movement while prioritizing caution. Therefore, understanding that the flashing yellow light signifies the need for careful driving helps maintain safety on the road.
