(Wanatah, IN) - A semi-truck driver could have saved a life after pulling beside a suspected drunk driver passed out behind the wheel where two state highways come together in Wanatah.

According to La Porte County Police, Scott Mills was behind a car at U.S 421 and U.S 30 early Sunday.  The traffic signal changed a couple of times but the car failed to move.  Police said Mills noticed the female driver unconscious and the car was still running.

According to police, Mills placed chocks under her tires to keep the car from rolling into the intersection if driver’s foot came off the brake pedal.  Police said the driver woke up once paramedics arrived and pushed down on the gas pedal to leave.  However, the chocks despite the tires screeching kept the car in place.

Alyssa Minix, 21, of Knox was arrested with an alleged blood alcohol level of .094-percent.
