Question

What is the purpose of the flashing light in some traffic lights?

Answer 1

The light indicates that the emergency signal priority system is interrupting the normal cycle of the signal to let traffic in the direction of the emergency vehicle to continue through the intersection. This helps to get the emergency vehicle through because it removes vehicles that would otherwise be stopped in their path.

Answer 2

Believe it or not, most people do not notice stop lights, and that is why so many people run them. They are too busy doing something other than paying attention to their driving. So they install those strobe lights to draw attention to it.. It works, you noticed it. (smile). . God bless you. carol Martin
