Rain appears to have contributed to several crashes on Highway 101 in Sonoma County sending at least one person to the hospital early Friday, according to authorities.

At least one person was taken to a Healdsburg hospital after being injured in a crash on the highway near Westside Road, an emergency dispatcher said. The crash reportedly happened just after 7 a.m., and involved a compact car and truck. The car’s engine caught fire but firefighters were able to extinguish it, according to reports.

A pickup truck heading south on the highway spun out near Airport Boulevard around 7 a.m., backing up traffic to Shiloh Road, according to CHP preliminary reports. Heavy rain was reported in the area at the time.

Minutes later, a northbound flatbed truck slammed into the center divide on the highway onramp in Penngrove.
