An SUV driver who was involved in a deadly crash on a Seattle bridge says a charter bus and amphibious tour vehicle were headed in opposite directions when they collided.
Twenty-three-year-old Brad Volm, of Philadelphia, says he was driving behind the duck boat, heading north on the Aurora Avenue bridge, when the amphibious vehicle swerved in front of him.
Volm says it appeared the duck boat's front left tire locked up, and the vehicle swerved into the oncoming charter bus.
Seattle police and fire officials didn't immediately describe the chain of events leading to the crash. But they say initial reports described it as a head-on collision.
The crash Thursday left four people dead and dozens injured.

Students and staff from North Seattle College's International Program were involved in the deadly crash between a charter bus and an amphibious tour vehicle.
School spokeswoman Melissa Mixon said in a statement that the wreck that killed four people and injured dozens occurred at about 11:15 a.m. Thursday. She says the uninjured students and staff were taken back to campus, where counsellors were on hand.

North Seattle College is a two-year institution with about 18,000 students. Mixon says it's trying to determine more information.
The charter bus was from Bellair Charters and Airporter, based in Ferndale, Washington. A message left with the company's president wasn't immediately returned.
The other vehicle was an amphibious bus operated by a tour company called "Ride the Ducks."

A witness says she was walking across a Seattle bridge just after a charter bus and an amphibious tour vehicle crashed and came upon a mess of jumbled metal and glass.
Jahna Dyer, a registered nurse, told The Associated Press on Thursday that some victims were sprawled out on the pavement while others milled about seemingly in shock and falling down.
Authorities say the crash killed two people and critically injured nine others. Dyer says she stabilized the neck of an injured man and helped a woman who had a cut lip and glass in her eye.
Another witness, John Mundell says he was at the south end of the bridge when he heard a screech and twisted metal and saw what appeared to be a few dozen people on the ground.
Mundell says wanted to help the injured but "felt helpless."
