NASHVILLE, Tenn. (WSMV) – It was money Shelli Hoover didn’t have. The ignition interlock device she was court-ordered to put on her car after being arrested for DUI cost $82 at the signing of the lease for the equipment. And the costs kept coming: $117 for “other charges,” and nearly $50 every two weeks. And that didn’t even include what she had to pay to have it installed in her car.
