A two-vehicle accident involving an 18-wheeler Monday night in Benton County sends three people to the emergency room.

The highway patrol says it happened on South Highway 65 at Route-AC when the car driven by 45-year-old Kimberly Martinez, of Lincoln, ran a stop sign striking a southbound freightliner driven by 60-year-old Kenneth Hicks, of Cross Timbers.

Hicks was uninjured while Martinez and one of her passengers, 24-year-old Taylor Thompson also from Cross Timbers, suffered serious injuries and were both flown to University Hospital.

A second passenger, 34-year-old Chad Tidwell-Kaska of Cross Timbers, suffered moderate injuries and was treated at a local hospital.

The driver, Martinez, also faces a pending felony DWI charge as a result.
