Monday afternoon, Summit Fire responded to the area of I-40 and Cosnino Road in Flagstaff for a vehicle fire involving a cargo trailer. Arriving crews were advised by the driver that there was smoke coming from under the trailer. Crews made access inside and found the fire. Due to the trailer being loaded to capacity, access was initially difficult. Additional units arrived and personnel were able to extinguish the fire. No injuries were reported and the cause is under investigation.
