A traffic collision on US Highway 101 South in San Mateo, CA, caused significant traffic disruptions today during the evening rush hour. The incident, which occurred around 9:02 PM, involved two vehicles: a black pickup truck and a black Lexus.

The collision resulted in debris blocking five out of six lanes, creating a hazardous situation for drivers. Emergency response teams promptly arrived at the scene to manage traffic and ensure safety. Traffic management procedures were implemented, and a tow truck was dispatched to remove the damaged vehicles, which included a pickup truck with front-end damage and a Lexus with moderate damage to its right side.

Due to the blockage, traffic congestion developed, leading to delays for evening commuters. While one lane remained open to allow some traffic flow, the closure of five lanes resulted in significant backups in the area.

Motorists are advised to seek alternate routes to avoid delays and exercise caution while navigating through the affected area. Emergency crews are working diligently to clear the debris and restore normal traffic conditions as quickly as possible. Updates on the situation will be provided as more information becomes available.
