Eighty-eight wrong-way drivers have been arrested on suspicion of DUI so far in 2019, according to the Arizona Department of Public Safety.

There have been 36 wrong-way collisions resulting in 16 fatalities during the same period.

This data appears despite the Arizona Department of Transportation's investing more than $3 million into a wrong-way driver detection system along a 15-mile portion of Interstate 17 and a new law allowing felony aggravated DUI charges for impaired wrong-way drivers.

“Statewide, we had 36 wrong-way collisions so far this year,” DPS spokesman Bart Graves said. “This is since Jan. 1."

Driving the wrong way on a controlled-access highway in Arizona carries a $500 fine and mandatory traffic school. If the driver is found to be impaired, they can be charged with aggravated DUI, a Class 4 felony.

Wrong-way drivers who cause fatal accidents can be charged with second-degree murder if impairment is a factor in the crash.
