HAE Fun Lab Complete Street Luge board and wheels. Also selling the Street Luge Survival Guide by Darren Lott. Wild Fro Racing Sno-Rider face shields, tire retread for brake shoes and glue. Of course going faster than the speed limit is speeding regardless of what you're riding. You are a pedestrian.
Pedestrian laws apply.
You can get a ticket for being in the roadway or blocking traffic. Check city, county and state laws. Most states have their vehicle codes posted on the Internet. Since 1994 I have encountered numerous police officers but have never received a ticket or had my board confiscated. If a law enforcement officer asks you to leave the road you are on, leave.
