From MSN Money and the Tax Foundation, here's how Maryland's gas tax stacks up against other states.
Maryland is tied with Massachusetts for the 26th-highest gas tax rate among U.S. states.
A 2007 study by the Texas Transportation Institute found that traffic congestion in the Washington-Baltimore corridor cost Maryland $3 billion per year, up 1200% since 1982. Maryland's gas tax rate has been unchanged since 1992.
