An armed woman sat in a lawn chair in the middle of a busy Texas highway on Thursday, sparking an hours-long standoff with law enforcement that caused traffic to stand still before she eventually surrendered.

Harris County Constable Precinct 4 deputies responded Thursday afternoon to a report of an armed woman who was involved in a crash involving an 18-wheeler on I-45 South in Spring, Texas. The woman and the driver of the truck were unharmed in the incident.

After the collision, the woman exited her vehicle with a chair and sat down in the middle of the highway. The constable’s office said the woman, who was armed with a handgun, was refusing to drop the weapon.

“That was something that kept her here with us from doing something foolish. Once she realized her daughter was here, she was safe, she was going to be allowed to see her again, it got better at that point,” the sheriff said.

The woman eventually surrendered and was taken into custody before being transported to a hospital for evaluation.
