EAST HAMPTON, N.Y. — Jason Kidd, the Knicks’ new point guard, declined tests to see how much alcohol he had drunk after his sport utility vehicle plowed into a utility pole in a residential neighborhood in the East End of Long Island early Sunday, the Southampton police said.

Kidd is to appear in court on Sept. 12 on a charge of driving while intoxicated. He has pleaded not guilty.

Kidd was also charged with failure to stop and refusing a breathalyzer at the scene of the crash. His lawyer, Edward D. Burke Jr., characterized those as “traffic violations.” Kidd also declined a blood alcohol test later at Southampton Hospital, where he was treated for minor injuries.

“I had a few drinks,” Kidd, 39, told the police as he left his vehicle, according to paperwork prepared by the Southampton police for prosecutors. “I was going home from a club. I don’t know what happened.”
