Topeka ? Gov. Kathleen Sebelius on Monday signed into law legislation aimed at increasing drug and alcohol tests at the scene of traffic accidents.

The measure – House Bill 2617 – was conceived by Dennis and Denise Bixby, of Tonganoxie, whose daughter Amanda, 19, was killed in a Valentine’s Day 2007 wreck near Basehor.

Upon hearing of Sebelius’ action, Dennis Bixby said he was relieved.

“A lot of people went to a lot of work to do all this,” he said. He commended state Rep. Kenny Wilk, R-Lansing, for introducing the bill.

The measure increases the authority of law enforcement to order a test for drugs or alcohol in a vehicle accident that results in a death or serious injury.

The Bixbys have said the driver responsible for the collision that killed their daughter should have been tested for drug use.
