(1) No person shall stand on a highway for the purpose of soliciting a ride.
Based Basically, hitchhiking is illegal based on the definition of highway, it . You CANNOT solicit rides form the shoulder or berm. It would be very hard to defend your position against an officer who claims you are breaking the law by soliciting a ride within the boundary lines of any "way"road property, therefor therefore avoid cops in this state at all costs!
The cops in the southern two thirds of the state can be tricky to avoid. The cops in the northern third of the state (highway 12 and all points north) seem not to mind hitchhikers as much.
