Municipalities in Vermont can have varying traffic laws. Burlington's ordinances, for example, have a few differences from State Statue.  They include:

• Prohibition of cycling two abreast on roadways
• Prohibition of cycling on the sidewalks in Burlington's "Inner Fire District" -- basically the downtown area bounded by Pearl Street, Winooski Avenue and Main Street.

For other municipalities, contact the local Town Clerk or City Clerk.
