The driver whose car hit the vehicle carrying David Halberstam, killing the Pulitzer Prize winning author and journalist, says he had the green light, the Chronicle reports.

Lewis Morris, 64, was driving toward the Dumbarton Bridge on Bayfront Expressway on April 23 when a Toyota Camry driven by UC Berkeley journalism student Kevin Jones, in which Halberstam (pictured) was a passenger, turned in front of him at the intersection of Willow Road.

“I could not slow down,” Morris told the Chronicle. “I didn’t have enough room to slow down. That’s basically all there is.”

Drivers turning left onto Willow from the expressway are controlled by a left-turn arrow.

Halberstam, 73, who was on his way to interview NFL Hall of Fame quarterback Y.A. Tittle for his next book, died at the scene.

Jones referred questions about the crash Tuesday to his lawyer, Laurel Headley, who declined to comment until the investigation is completed. Police expect to wrap up their inquiry by next week and review the case with the San Mateo County district attorney’s office, the Chronicle reports. (AP file photo, 1993, by Mark Lennihan)
