A shuttle bus carrying 55 Tesla employees collided with a VW bug on I-580 this morning near the Altamont Pass, killing the driver of the VW. As CBS 5 reports, the deceased driver is said to have been an off-duty law enforcement officer, but he or she has not been identified and nor has the agency they worked for. Photos from the scene show the rear portion of the car sheared off, and according to KRON 4 the car was rear-ended by the bus.

The crash occurred around 7 a.m. as the bus was en route to Tesla's plant in Lathrop, outside of Tracy. The bus driver told CHP investigators, per CBS 5, that "the early morning sun was in his eyes" as he was heading eastbound on 580, and he did not see the VW in front of him.

The Chronicle reports, via investigators, that the VW was "driving slowly when it was suddenly rammed into by the bus."

Reportedly, one passenger on board the bus suffered minor injuries, but was not taken to a hospital.

One-hour traffic delays were expected as a result of the collision, which shut down three lanes of eastbound traffic indefinitely.
