http://gomdot.com/bicycling/laws.htm is a MS Dept. of Transporation page listing laws pertaining to bicycles in this state.
I'd only known of a couple of these prior to this evening, so this was an interesting find.
I've made a .pdf file with this information and printed it off for future reference. I'm thinking it may be handy to have a copy sealed up in a freezer bag to carry along when biking on the roads.
MDOT's site turned out to have a bunch of info not found on other sites I've found, including:
P.O. Box 1850
Jackson, MS 39215-1850
MDOT's got a Bicycle/Pedestrian Coordinator? Cool. That info might come in handy.
