A traffic collision occurred today on US Highway 101 North at Del Rio Road Off-Ramp in Atascadero, CA, leading to significant traffic disruptions. The incident took place around 9:03 PM and involved one vehicle that lost control and veered off the roadway, coming to rest on the right-hand side in the grass.

Due to the vehicle being non-drivable, emergency units were dispatched to the scene to manage the situation.

This response resulted in lane closures, which caused delays and backups for motorists in the area.

As emergency responders worked to control the scene, a tow truck was requested to remove the vehicle. The ongoing emergency response efforts have led to congestion, and drivers are advised to seek alternate routes to avoid the impacted area.
