(AP) — A Colorado man has been hospitalized following a car crash in the Nebraska Panhandle.

Scottsbluff police say 35-year-old Grant Ross, of Sterling, Colo., was driving eastbound Monday on the South Beltline Highway when he clipped the rear of another eastbound car.

The second car was pushed into the median. The car driven by Ross continued east and eventually veered into the parking lot of a nearby business. It struck a parked vehicle, which hit another parked vehicle.

Police believe Ross’ erratic driving was caused by a seizure. Ross is the only person involved in the crash that was injured, and he remains in serious condition at a local hospital.
