PHOENIX (FOX 10/AP) - Authorities say the driver of a semi-truck has been arrested for DUI after driving the wrong way on a Valley freeway.
The Arizona Department of Public Safety says the semi-truck was pulled over early Friday morning on Interstate 17 near the Interstate 10 split.
The truck was spotted driving the wrong way on I-10 before it was pulled over by DPS.
The driver has not yet been booked into jail.
Metro Phoenix has had a spate of crashes and other incidents of wrong-way vehicles on freeways, and state officials are taking a variety of steps to try to curb the problem.
Those steps including installing "wrong way" signs on freeway off-ramps and testing a camera system on part of Interstate 17 to detect wrong-way vehicles, warn other drivers and notify authorities.
