The "flashing lights" are supposed to be turned on/off by the contractor at the beginning/end of the workday.
Guess what happens? Constantly? The "flashing lights" are ALWAYS frickin' flashing! A**hole Union workers are too lazy to turn the lights off.
I went through a construction zone in Mt. Lebanon (South of Pittsburgh) many times last Summer on my way to the golf course, sometimes as early 5:15AM... on a Saturday or Sunday morning. Flashing lights everywhere. Stupid.
and yes, they usually leave the lights on all the time and there are drivers & state cops both that think the speed limit applies whenever the lights are flashing, even if no workers are present
