Dramatic I-80 crash caught on video

WHOA!  Luckily there were no injuries in this crash on I-80 Wednesday. The Iowa DOT can't stress enough the importance of paying attention when you're behind the wheel.

The semi hit an Iowa DOT attenuator truck (with huge flashing arrows on the back) that was at the back end of a painting operation. 

The truck  did its job and absorbed the impact. Other traffic was able to avoid  getting tangled up in the crash.
