The Vanderburgh County Sheriff's Department says the Evansville man's blood-alcohol content was 0.26, more than three times Indiana's legal limit.
Police say Wallace's ex-wife called police Sunday to say Wallace was bringing their two children home following a visit and may have been drinking.
Wallace allegedly accelerated and drove past his ex-wife's home to avoid deputies. A witness says he heard the children screaming and crying after Wallace ran over a curb, jolting the vehicle.
