-The traffic light that's on the turn to get to everything you need to get to and often with a limited amount of time left

Ex. I only had a few minutes to get to school because I set my alarm to PM instead of AM like a dote. Had to wait for this friggin' thing to change for well over five minutes and ended up late to home room. Same thing happened when I had to catch a train and matters were made worse because I got stuck behind a slow ass truck.

This is also the same light that you must wait for if you want to get to the Post Office or CVS to get a prescription before they close.
