A yellow flashing light on a vehicle is a warning to you to do what?

A yellow flashing light on a vehicle serves as an important warning signal to drivers on the road. When you see a vehicle with a yellow flashing light, it indicates that you should slow down. This signal is often used by emergency vehicles, construction crews, or other types of service vehicles that may be operating in or near the roadway, prompting drivers to exercise caution and be prepared for unexpected activities such as vehicle stops, personnel working, or equipment being used.

Slowing down allows for better reaction time and increased safety for yourself, the flashing vehicle, and any potential hazards or obstacles in the area. Maintaining a reduced speed gives you the ability to assess the situation more effectively and make safer driving decisions.
