A growing number of states are starting to adopt "move over" laws to help protect emergency workers, and this video posted by the Massachusetts State Police on its Facebook page shows the importance of said laws. Captured by a traffic camera in the Thomas P O'Neill Jr. Tunnel in Boston, the video shows a trooper alerting traffic of upcoming lane closures and a small black car (shown above) narrowly missing hitting the cruiser at a high rate of speed.

The tunnel's speed limit is 45 miles per hour, and while it's hard to say if the driver was speeding or not, the caption on the Facebook page said that the construction area was well signed. The driver was not impaired, we read, but obviously wasn't paying attention either. Scroll down to watch the video and see just how close this whole situation came from getting really messy.
