A significant traffic collision occurred today on Interstate 5 South (I-5 S) at the Roscoe Boulevard on-ramp in Los Angeles, CA, causing major disruptions during the morning commute. The incident involved two vehicles: a white Volvo XC90 and a tractor trailer.

At approximately 9:33 AM, the traffic incident began when the vehicles collided, leading to a jackknifed semi-truck that blocked the high-occupancy vehicle lane and the first two lanes of traffic. This resulted in all lanes being obstructed and traffic coming to a complete stop, creating substantial congestion and delays for motorists in the area.

Emergency response teams were quickly dispatched to the scene to manage traffic flow and control the situation. A tow truck was requested to assist with the removal of the vehicles involved in the collision. A Sig Alert was issued shortly after 9:49 AM, indicating that the high-occupancy vehicle and the first two lanes would remain blocked for an undetermined duration.

Motorists are advised to seek alternate routes to avoid the backup and delays caused by this traffic incident. The situation is still developing, and drivers should remain cautious as crews work to clear the scene and restore normal traffic conditions.
