Naked Woman Atop Semi Ties Up Traffic for 2 Hours She may have been involved in a string of crashes beforehand By Evann Gastaldo, Newser Staff Posted Mar 7, 2016 4:30 PM CST 45 comments Comments A screenshot from the Houston Chronicle's video. (Houston Chronicle) (Newser) – The bizarre reason for a two-hour traffic delay during the morning commute in Houston Monday: a naked woman. The nude woman wandered into traffic on US-290 around 9am, a Harris County sheriff's deputy tells the Houston Chronicle; the situation caused a three-car pileup (some outlets imply that was due to her walking into traffic, while others say she may have been driving one of the cars). At some point the woman climbed on top of a 15-foot-tall big rig, where she occasionally danced and also yelled at authorities. (KCEN notes that she was seen "twerking and gyrating" at various points.) It's not clear exactly how she got on top of the 18-wheel truck. Authorities believe the woman was first involved in two separate hit-and-runs nearby, and entered the highway after allegedly fleeing those and ditching her clothes. The highway was shut down in both directions during the incident; firefighters finally got her down from the truck at 11am. The scene drew spectators, and one says that while the whole thing started out "funny," it ended up "kind of saddening." She was taken to a hospital for a mental health evaluation; it's not clear whether she will be charged with a crime.
