There was a possibility that Tiger Woods (US), who was seriously injured in a car rollover accident, was driving drowsy.

Foreign media such as USA Today and Fox News reported on the 2nd (Korean time) that Woods could have fallen asleep at the time of the accident based on the opinions of vehicle forensics experts.

On the 24th of last month, while driving a Genesis GV80 vehicle on a road in California, USA, Woods suffered a leg injury in a rollover accident and underwent surgery.

The car rolled over the center divider on the road, hit a tree, and stopped.

In this accident, Woods broke a bone in the lower part of his right leg.

Experts say this indicates that Woods was applying the brakes at the moment of impact.

It could also be evidence that Woods hit the brakes too late.

Court appraiser Jonathan Cherney said, "A vehicle going straight on a curved road is typical of drowsy driving."

He said that he had investigated the accident himself, and said that Woods "it seemed like he was unconscious, medically afflicted, or fell asleep, and he didn't wake up until then."

Cherney added that he had not seen evidence of Woods moving the steering wheel to avoid an accident.

Los Angeles County Sheriff Alex Villanueva says there were no skid marks on the road, tire marks that occur when you hit a hard brake.

Accident reconstruction expert Felix Lee said the car he was driving was equipped with anti-lock brakes.

"I don't think speed is a big problem," said Lee, and decided that'carelessness' could be the cause of the accident.

Rami Hashishi of the National Institute of Biomechanics who investigated the accident said that Woods showed a very delayed reaction when the accident occurred.
