We haven't heard much about The Hangover Part III since production started in Southern California last month. Today, a new video and photos from the set have surfaced, featuring Zach Galifianakis as Allen. The actor was spotted driving a Mercedes-Benz on an Orange County freeway, hauling a large trailer that reportedly carries a giraffe inside. Take a look at the photos and video, featuring the aftermath of this crash, plus details regarding the scene from an onlooker.

"Allen was driving down the freeway in a brand new Mercedes-Benz E350 Convertible. The Mercedes had the license plate DADSBOI, which is funny since Allan's parents are always spoiling him. In the back he was pulling what appeared to be an animal trailer. Later I found out the trailer is actually for a giraffe that gets loose on the freeway after Allen crashes his car into a semi truck. It was crazy, there was tons of smoke and the cargo from the semi truck spilled all over the freeway. After the crash I saw Zach Galifianakis running from the scene. The cops had the whole place on lockdown and tried to make sure nobody could see what was going on. I was able to get some footage of the crash right before a motorcycle cop made me leave."
