New jersey has had a fast lane is the pass lane only law since the early 90s and cops ticketed people that didnt abide by it.
That law should be universally in place. Good luck teaching most of this state’s residents that one. I grew up knowing that law so I do it all the time unless some shitbox is driving erratically at which point I choose to slow down and box them in.
As far as the emergency light law, I move over if there is room in the lane to the left mostly because of those videos you see of someone getting clipped. I dont want to clip someone on the side of the road so I move over whenever possible, be it a cop, towtruck or stopped vehicle.
