Pocci, 47, is deaf and testified through an interpreter.
On the stand, Pocci described what was going through his mind as he pulled up to the intersection in the Gaslamp where the parade was passing through on July 26, 2014.
“At first, it was confusing as to what’s going on. What are all these people walking by? Then it seemed like it was a parade – but it was zombie people," testified Pocci.
Pocci said he turned off his car for 10-15 minutes, but grew impatient. He said he turned the car back on and honked -- which caused people to surround the car.
Pocci said two men sat on the hood and he started to fear for the safety of his passengers, which included his fiancee, her nine-year-old son and her sister.
“I felt threatened, I felt scared. I felt I had an obligation, a responsibility to keep them safe," Pocci said.
Pocci sped through the intersection, hitting a woman who severely injured her arm and leg.
“I felt a bump and I didn’t know what it was -- I thought it was a curb," Pocci said. “I think about her, poor woman. I couldn’t believe I hit a woman. I’ve never hit anyone in my whole life.”
Pocci faces up to three years in prison, if convicted.
