In recent decades, the number of Americans using bicycles as their main form of transportation has been on the rise.  The increased number of  cyclists on the road has made it difficult for both drivers and riders to safely navigate through traffic.  The Washington Post reports that eleven cyclists died last year on Maryland roads, an increase from 2008. A new law that goes into effect today mandates that drivers can be fined as much as $500 if they pass within three feet of a cyclist.  The law also states that cyclists must ride responsibly; maintaining a steady course and using bike lanes and shoulders when present.
