US authorities say there's no immediate evidence that Tiger Woods was impaired in a car crash in Los Angeles that seriously injured both of the golfer's legs.

At a news conference, the police chief and fire chief of Los Angeles County didn't answer follow-up questions on how they know he wasn't impaired or how fast he was driving.

Weather was not a factor in the crash.

Authorities say Woods was conscious and able to communicate when authorities arrived to pry him from an SUV after a rollover crash this morning.

He was taken to a hospital in serious condition and is having surgery after suffering multiple leg injuries in the accident.

A spokesman on a US television network said Woods has “non life-threatening injuries”.

ESPN later reported that Woods may have broken both of his legs in the crash.
