A significant traffic collision involving six vehicles occurred today on Interstate 405 South near Brookhurst Street in Fountain Valley, CA. The incident took place during the morning commute, causing substantial traffic delays and congestion in the area.

The vehicles involved included a Black Honda SUV, a Black Honda CRV, a Black Nissan, a White pickup truck, and additional vehicles that contributed to the crash. As a result of the collision, several lanes were blocked, leading to a backup for motorists traveling through the area.

Emergency response teams arrived promptly to manage the situation. Officers positioned themselves on the scene to direct traffic and facilitate the clearing of the roadway. A tow truck was called to remove at least one vehicle, specifically a Dodge pickup truck, while efforts were made to move other vehicles to the roadside to minimize traffic disruption.

Witnesses noted that the Black Honda CRV was observed swerving in and out of lanes prior to the collision, which may have contributed to the incident. Traffic cameras indicated that the best route for drivers to avoid delays was southbound on Interstate 405, just south of Newland Street.

Motorists are advised to exercise caution when traveling through the area as cleanup efforts continue. The situation is expected to improve as vehicles are cleared and normal traffic flow is restored.
