Ashley McIntosh, 33, had a green light when she went through a Route 1 intersection in Alexandria in February 2008. The police officer who ran into her car did not. The officer had turned on her flashing lights, but was not using sirens, and McIntosh was killed.
The accident happened close to the home of Virginia Sen. Toddy Puller, who sponsored a bill that's become known as Ashley's Law. The bill requires all emergency vehicles in the state to use lights and sirens in most emergency situations, or else slow down at intersections.
"It's one of the policies of Fairfax County police, which that obviously this woman did not follow," Puller says of the officer involved in the crash. "But it was not state law."
Puller says she first crafted the law in 2009, but a lawsuit filed against Fairfax County by the McIntosh family prevented the General Assembly or the crime commission from considering it until the case was settled.
