Commuters on Highway 290 this morning had an unexpected surprise when a naked woman climbed on top of an 18-wheeler after an accident in Houston.

Officers were called to the scene before 9 a.m. Monday after reports of a car accident.  When they arrived, they found the woman undressing on top of the 18-wheeler.  Houston TV stations even caught the woman twerking at passing vehicles.

Firefighters moved a tower truck next to the big rig, but the unknown woman spit on them.  Eventually, authorities were able to take her into custody.

All lanes of traffic were closed in the area for more than two hours as a result of the accident. The woman was taken to a local hospital for a mental health evaluation.
