HITCHHIKIN' LAWS

But if it was illegal then there would be "pedestrians prohibited" signs at every ramp but since there are none in OR and I'm assuming there are none in MT than I don't think there is a law, at least not a state law prohibiting it.

I got dropped off at almost every exit on the I-76 from colorado to nebraska and there were not any "no pedestrian" signs, but when I decided to walk along the freeway a state trooper pulled up and told me that it's illegal to walk along the freeway.
