I think its legal here in WA, however you must use your blinker when crossing the turtles.(according to a friend of mine thats a cop)Here in WA the cagers get their roadrage up when you do this,In CA it seems to be acceptable what about other states and cops PLEASE chime in.
One time a cager bumped me on purpose and :twofinger at the same time, I parked it and went to his window and asked him what the hell he thought he was doing, "just being rude like you,want me to get out of my car and show you more?"I just told him I was wearing protective gear and a helmit,your not,so bring it. He apologized.
