The brunette, who has not been identified, was seen striding down the busy BR-262 highway in Manhuacu, Brazil on Sunday.
A driver, who saw the woman and filmed the bizarre scene, tried to ask her if she needed help but she ignored him.
Julio Sales said: ‘I saw her and thought it was funny. She was holding a drink in one hand and her clothes in another.
‘Drink makes people do things that in normal judgement they wouldn’t have the courage to do.’
The woman was later taken to the UPA hospital in the city by the local fire service.
Military Police and Federal Highway Police were also alerted, who said they had not arrested the woman.
A spokesman said: ‘The woman was questioned and released. There was no action taken against her.’
