The speed limit includes all the lanes.
I have good insurance on my vheicles and as long as my family isnt with me I brake check very hard. Cop or not thats crap and asking for a problem. I would have laughed if the cop rearended him.
One of the great things about semi's is I cans slow down at a decent rate without my brake lights ever coming on. I used my engine brake on a cop who was doing that to me on 31 once. He pulled up beside me and told me I was number one.
So, are you suggesting that you hang out in the left lane merely because the speed limit applies to all lanes?
