Tennessee: Move it on Over: Despite Laws, Simple Traffic Stops Still Put Police in Crosshairs

In 2006, Tennessee became the 30th state to pass a "Move Over Law," creating a safety zone to protect police working along the sides of roadways. It has since been amended to include firefighters, other emergency personnel and utility workers.

It requires that passing motorists merge into the adjacent lane of traffic — when safe to do so — or when moving over isn't possible, slow down for emergency vehicles. The penalty for violating Tennessee's "Move Over Law" is a maximum fine of up to $500 and possibly up to 30 days in jail.
