A serious traffic collision occurred on the northbound side of U.S. Highway 101 near the Humboldt Hill onramp on February 5. The accident involved an Isuzu Tracker and a construction crash truck, with authorities responding around 3:33 p.m. The incident resulted in injuries, including a female suffering a hemorrhage from her hand. One vehicle was reported in the roadway, blocking one northbound lane, and an ambulance was dispatched to the scene. Initial reports indicated that a silver vehicle collided with another, and the scene was captured on video by a witness. The California Highway Patrol is investigating whether the crash was caused by unsafe conditions in the construction zone, which can be hazardous despite safety measures like crash attenuator trucks. Experts note that poorly managed work zones can lead to liability for construction companies or public agencies if negligence is involved. Personal injury attorneys recommend consulting experienced lawyers to pursue damages, especially when unsafe work zone conditions contribute to accidents. The incident highlights the dangers of merging traffic and the importance of proper highway safety protocols.
