A significant traffic collision involving six vehicles, including a semi truck, occurred today on Interstate 5 South near Weldon Canyon in Los Angeles County, CA. The incident took place during the busy afternoon traffic hours and involved a white Tesla Model Y, a black Toyota, and a white Acura MDX, among others.

As a result of the crash, multiple lanes—specifically lanes 3, 4, and 5—were closed, leading to considerable delays and congestion on the freeway. Emergency response units were quickly deployed to manage the scene and control traffic flow. A tow truck was called to assist in removing the vehicles involved in the collision.

The blocked lanes caused significant backups, impacting traffic for approximately 30 minutes. While lanes 1 and 2 were reopened shortly after, lanes 4 and 5 remained obstructed for an additional period, prompting officials to issue a sigalert to inform drivers of the ongoing traffic incident.

Motorists are advised to seek alternate routes to avoid delays as cleanup efforts continue. The situation is being monitored, and further updates will be provided as the scene is cleared. Drivers are encouraged to stay alert and exercise caution while navigating the affected area.
