ST. PAUL, Minn. - St. Paul police say the driver who crashed into a Metro Transit bus in St. Paul Friday night showed "preliminary signs of impairment."

One person is dead and two are critically injured after the car struck a bus at the corner of Dale Street and Charles Avenue, nearly cutting it in half.

St. Paul Police spokesman Steve Linders says a 26-year-old Minneapolis man was driving eastbound on Charles when he became involved in a minor traffic accident and fled the scene. He was driving at an estimated 70 miles per hour when the driver lost control, hit a median and went airborne, flying into the side of the bus.

Linders says a passenger, 48-year-old Kenneth Foster of Minneapolis, was ejected from the bus and died at the scene. Another passenger, a 19-year-old man, was critically injured and taken by ambulance to Regions Hospital. He was rushed into surgery, and Linders said he may not survive.

The driver of the car was also critically injured and is being treated at Regions.

The car struck the Metro Transit bus broadside, nearly cutting it in half. 

Police say there were 6 to 8 passengers on the bus, which was running Route 65.

A veteran patrolman on the scene said it was the worst traffic accident he'd seen in decades on the police force. Blood will be drawn from the driver of the car to determine if he was under the influence of drugs or alcohol at the time of the crash.
