It is the law in Illinois to slow down or move over one lane for stopped police, fire, or service vehicles. Due to the lack of forethought I've seen on the road I move over for all vehicles on the shoulder.
As far as the full face helmet goes with pepper spray....I have vents that go right up my face.
Yes, same way here in NC, you must move over for Emergency vehicles..
oh, good point about the vents, never thought of that.
