A Department of Public Safety trooper who was off-duty was in the right place at the right time to stop a wrong-way driver in Phoenix.
DPS said she was driving home just before 5 a.m. on Sunday when she spotted the driver going north in the southbound lanes of the Interstate 17 in the area of the Stack.
She was able to stop the driver and call for back up. The driver stopped just south of Northern Avenue.
The suspected wrong-way driver was arrested and troopers said impairment is suspected.
