SOUTHERN HUMBOLDT- The following is from Garberville CHP:
On Friday, at approximately 4:30 AM, A 2013 International Pro Star truck tractor, pulling a set of doubles freight trailers, was traveling northbound on US-101, north of Twin Trees Bridge (MPM 6) in Humboldt County. 60 year old Frank Martinoni, of Petaluma, Ca., was the driver of the semi-truck. For reasons still under investigation, The driver of the truck allowed the right side tires of the rear trailer to run off the east roadway edge of US-101 and into a drainage ditch. This resulted in the driver losing control of the trailer as it began to fishtail. The rear trailer overturned onto its left side and came to rest in the #2 lane of northbound US-101. The truck tractor and the lead trailer did not overturn. The driver was uninjured as a result of the collision.
