Wrong-way drivers becoming an increasing problem in the Valley

We've seen multiple wrong-way crashes this week and another one last night. This one happened in Casa Grande on the I-10 near State Route 387. The wrong-way driver collided head-on with a commercial vehicle which was then rear-ended by another car. Police say the wrong-way driver appeared to be impaired. She was taken to the hospital to be treated for injuries from the crash and will face a number of charges. We're told the drivers of the other two vehicles are OK. This is the fourth wrong-way crash in Arizona this week.
