send an email to the state bike & pedestrian coordinator bikes AT sha.state.md.us

They'll send you multiple copies of things if you ask.
The booklet I keep is The Maryland Vehicular Law Pertaining to Bicycles with Definitions
It's older and missing the 6th item in lane position about being able to take the lane if it's too narrow to share (21-1205), so I pulled that bit of code from the state code on line, printed out and stapled it into the book. It's probably the most relevant thing. In any event I doubt anyone I've given it to has read it. It's the fact that it has a state seal on the cover and says the words "bicycle" and "vehicular law" which gives you instant credibility.
