PLACER COUNTY — Five people were injured in a multi-vehicle collision along Interstate 80 in Placer County, officials said Friday afternoon.

It happened shortly after 2:30 p.m. in the westbound lanes of I-80 at Drum Forebay Road. In total, 18 vehicles, including a Cal Fire pickup truck, were involved in the collision.

All injuries were described as minor.

Cal Fire's Nevada-Yuba-Placer unit said westbound I-80 was closed at Truckee but has since reopened. Eastbound traffic was open but delayed.

At this time, it is unclear if the weather was a factor in the crash. The collision happened as a major storm rolls through Northern California, bringing snow, rain and slick roads.
