A traffic collision involving two semis occurred today on Interstate 80 (I-80) in Colfax, CA, leading to significant traffic delays during the morning commute. The incident was reported around 11:29 AM and involved one semi that jackknifed, blocking the second lane of the highway.

Emergency services promptly arrived at the scene to manage traffic and ensure safety. The situation escalated when a rear-end collision was reported, as one semi had to stop due to the blocked lane, resulting in another semi colliding into it.

In addition to the traffic disruption, approximately 50 gallons of diesel fuel spilled into a storm drain, prompting environmental safety measures. A tow truck was called to assist in the removal of the jackknifed rig and to restore normal traffic flow.

Motorists are advised to expect delays and consider alternate routes while traveling through this area. The scene was eventually cleared, but residual traffic backup may continue as the situation normalizes. Updates on traffic conditions will be provided as the aftermath of this traffic incident unfolds.
