She could be seen from traffic cameras.

By 10 a.m. authorities were still working to get the woman down.

KPRC reported that the woman was dancing, sitting and standing on top of the truck at various times.

At one point a firetruck with an aerial tower moved next to the big rig as officials, standing on a the truck's platform, tried to talk to the woman.

She was seen on traffic cameras spitting on at least one official.

It is not known why the woman climbed the rig and got undressed in the first place.
