Washington State Patrol troopers are imploring drivers to "wake up" to the dangers of drowsy driving.
In 2010, there were 17 people killed and 74 seriously injured in the state because motorists were either drowsy or had fallen asleep while driving, troopers said.
Nationally, drowsy driving resulted in 1,550 deaths, 71,000 injuries and more than 100,000 collisions each year, according to the National Highway Traffic Safety Administration.
"It always breaks my heart to hear that someone was killed or injured because a driver fell asleep at the wheel," said Chief John Batiste. "These are totally preventable deaths and collisions."
