I've found that most states will sell you a copy of the Vehicle Codes for a few bucks (almost always less than ten) and they're a lot easier to wade through than the websites - plus, you can highlight, add bookmarks, underline, whatever - and carry it with you. It's a step better than a printout when you're showing it to a cop...
I get my copy every three or four years (about when I renew my license) for $5 or so, and it's saved me thousands in fines, equipment crap, and things like that.
The last time I used it was to prove that yes, the use of hand signals for indicating traffic maneuvers is actually legal (ran across a CHP that didn't know that...)
