The law requires drivers to either move over one lane, or slow down below the speed limit when approaching stopped emergency vehicles.

In 2010, trooper Marc Castellano was killed by a passing driver in Monmouth County.

His mother is now working to ensure no one else has to endure the pain she felt after losing her son.

The new bumper sticker campaign was launched to coincide with the start of the busy summer driving season.
