I'm really confused. In what state is it illegal to "pass on the right" when on a freeway or interstate? Granted, I've virtually lived my whole life in the "armpit of the midwest", but I'm not aware that it is illegal to pass on the right when on a freeway or interstate highway? In fact, I make it a habit to "stay right unless passing", which I learned in Driver's Ed back in 1968 and it appears that nowadays, 85% (or more) of the current drivers have forgotten that or ignore it. It seems most drivers come down the on ramp and immediately go into the middle or left lane and virtually "park" their car there forcing people to pass them on the right. They seem to think it is their "right" to choose an interstate lane and drive at whatever speed they choose ignoring that they are in fact breaking the law by not yielding to faster drivers. What they don't realize is that the faster driver trying to get around them might just be having an emergency and is driving to the hospital because someone had a heart attack, someone got stabbed or shot, or their wife is about to deliver. I ALWAYS yield to faster drivers just because I have NO IDEA why they are driving faster. True, they might just be idiots that like to drive faster, but do you really want to jeopardize a life because you SUSPECT they might not have a reason for driving fast? Yield to them, move to the right. If they have no reason for speeding, they just might find karma a mile or two up the road when a trooper pulls them over.
