Miami - Golf superstar Tiger Woods looks disoriented and unsteady in police video of his Monday arrest on a charge of driving under the influence, according to footage obtained and broadcast by US media on Wednesday.
The video, from a dashboard camera in the vehicle of Jupiter, Florida, police officers, shows Woods unable to tie his shoe and wobbling as he tries to walk along a straight line in a field sobriety test.
Woods has blamed the DUI arrest near his home on an adverse reaction to prescription medication.
The police report on the incident, made public on Tuesday, said Woods was "cooperative" and "confused" when found by police, with "extremely slow and slurred speech."
The video seen Wednesday backs up that report.
Woods is unable to follow a light with his eyes when asked to do so. When officers ask if he understands instructions to recite the alphabet, he says he was asked "not to sing the national anthem backwards."
At one point in the sobriety tests Woods asks, "What are we doing?"
He was discovered by police asleep in his car in the right lane of a road, his right turn indicator blinking and the motor running.
Both tires on the driver's side of Woods's Mercedes were flat at the time of his arrest, and there was damage to the front and rear bumpers.
Woods told police he was taking several prescriptions, including two painkillers. His breathalyser test showed no sign of alcohol.
"I understand the severity of what I did, and I take full responsibility for my actions," Woods said in his statement on the incident.
"I want the public to know that alcohol was not involved. What happened was an unexpected reaction to prescribed medications. I didn't realise the mix of medications had affected me so strongly."
Woods's arraignment in Palm Beach County court is scheduled for July 5.
Woods announced last week he had undergone a fourth back surgery in April that will keep him off the course for the rest of the 2017 season, and he is unlikely to engage in strenuous physical activity for months.
He attempted a comeback after more than a year away from the game late in 2016 but played in just three tournaments.
After coming back at an unofficial event in December, he missed the cut in January at the Farmers Insurance Open and withdrew after one round of a tournament in Dubai in February.
