An unidentified naked woman danced on the cab of a semi-truck and stopped traffic on Highway 290 in Harris County, Texas, on March 7 (video below).
The 25-year-old woman had been in two traffic accidents earlier in the day and then slammed her car into a concrete barrier on the highway, according to KHOU.
The woman then reportedly got out of her car, took off her clothes, and climbed on top of a big rig that had stopped behind her.
Westbound traffic came to a halt for more than two hours while the woman danced nude and sat on the cab of the truck.
"That's the most horrific thing I've ever seen, and I'll be 68 in two days," Pearly Ward, a witness who called 911, told KHOU.
"And I said, 'In the name of Jesus I bless you and hope things will be okay for you,'" Ward added.
Firefighters and police officers tried to get the woman to come down off the 18-wheeler, but she reportedly yelled profanities at them and stood her ground. Police then climbed on top of the truck and wrestled her into the ladder truck basket.
The driver of the big rig refused to talk on camera because of his employer but told ABC 13 off camera how the woman drove in and out of traffic and later jumped on the cab of his 18-wheeler.
"I can't repeat most of the things she was saying but she was very confused and had a lot to say," Brian Shirley, of the Cy Fair Volunteer Fire Department, said.
"And the big thing was to try to keep her calm because if she got excited she could fall off that truck," Shirley told KHOU.
Authorities have not said if the woman will be charged with any crimes. She was taken to a local hospital to be evaluated.
Family members told ABC 13 that the woman has a history of mental illness.
