But what happens when you see a vehicle displaying a flashing green light?
For many drivers, the sight can be confusing. Green warning lights are much less familiar than red, blue, or amber signals, and their meaning can vary depending on where you live.
In some areas, green lights may identify volunteer emergency responders or specialized service vehicles. In other locations, they may be used for specific emergency operations or other authorized purposes.
The most important thing to remember is that green warning lights do not have one universal meaning everywhere.
