Photo Tualatin Valley Fire & Rescue Crews treat the driver of a compact car involved in a head-on collision with a dumptruck Thursday in Aloha, Ore.

Crews arrived to find the two vehicles on the sidewalk and the 61 year-old male driver of the Hyundai Azera lying on the ground next to the car. He was assessed and treated by emergency crews and transported to a local hospital by Metro West Ambulance. As a precaution, the driver of the truck was also transported to a hospital via ground ambulance.

Before leaving the scene, crews placed absorbent material on the roadway to mitigate the 50-yard oil slick resulting from the collision.

The incident is being investigated by the Washington County Sheriffs Office.
