Was a real life Beerman.....
In CDL class A training, a point was made that if you can't stay within 15mph of the speed limit, your 4 ways need to be turned on.
I'm gonna go off topic for a sec, I held a Class A and it's previous equivalent for 35 years If you're on a highway or interstate and you're running under the speed limit you should have your flashers on to notify people coming up on your that you're traveling lower than the limit, it's not only common sense, it's a courtesy and a notification of traffic behind to to switch lanes.
