EUGENE, Ore. - A driver came upon 3 vehicles stopped at a light in thick fog and couldn't stop in time, causing a 4-car crash Wednesday morning, Oregon State Police said.
The crash sent 1 person to the hospital with unknown injuries.
Highway 99 southbound was closed for about 30 to 45 minutes at Highway 36 while troopers investigates and tow trucks cleared the wreckage.
Trooper Jacob Luquin said 3 vehicles were stopped at the light when a fourth vehicle hit them from behind.
"There was thick fog at the time. I know it doesn't look like it now, but climates can change quickly," Luquin said. "Looks like a vehicle was traveling, didn't see the traffic control device, came upon some stopped vehicles and just wasn't able to stop in time. So we had the domino effect of one vehicle hits the one and it just kind of launches the others forward."
Three of the vehicles had to be towed. One was driveable.
Luquin urged drivers to leave space between cars and use caution when weather obscures visibility on the road.
