The 21-year-old man was driving south on Interstate 280 near Black Mountain Road when he lost control of his blue Toyota Supra, veered left and crashed into a tree at about 7:40 a.m., CHP officer Curtis Glace said.

He was pronounced dead at the scene, Glace said.

The fast lane was blocked as crews worked to clear the road, Glace said. The lane was reopened by about 9:40 a.m., he said.

Glace said it appeared the Toyota's rear right tire blew out, causing the crash. No other vehicles were involved.

The man was driving alone, he said.

The crash remains under investigation but no drug or alcohol impairment is suspected, Glace said.

Anyone with information on the crash, or who may have witnessed it, is asked to call the Redwood City-area CHP office at (650) 369-6261.
