Riding bikes on highways/freeways?

[Rizuin]

Is it illegal? I live by a highway called Route 15 and I don't see a sign saying "no" I've seen people do it. I know it's dangerous. I don't care! I've ridden down a hill that's life threatening 1000 times! And by "bike" I mean a manual powered 2-4 wheel bike. No motor. I'm asking this because my dad is always working, my brother's in WV, and I can't afford a taxi! I LIVE IN THE FICKIN' SUBURBS! So my only option at the moment is to go there by myself. I want serious answers. Not "You're insane"

yes you can ride your bike, but you have to wear a helmet and obey all traffic laws, so i would make sure a learn the hand signals for turning and stopping.
