A motorist’s dash cam captured a heart stopping crash on I-25 in Colorado over the weekend.

The video was captured around 2:30 p.m. on Saturday, April 16, on northbound I-25 in Thornton, Colorado.

In the video, you can see a white Toyota Sienna weaving between vehicles on the interstate, then cutting off a red Toyota Sienna, causing the red vehicle to hit a motorcyclist in the next lane. The motorcyclist is thrown from his vehicle and the unmanned motorcycle continues without him, striking a semi truck.

The motorcyclist was not seriously injured, according to the Denver Channel.

The Thornton Police Department is seeking the driver of the white Toyota Sienna.
