VIDEO: Last-second mergers get instant justice courtesy of Massachusetts State Police

A recent viral video shows Massachusetts State Police pulling over vehicles for merging at the last moment to avoid traffic on Storrow Drive.

The video was shared by Only In Boston on July 5.

In the video, you can see a trooper at the bottom of the screen monitoring traffic until he spots what he was looking for — a black SUV whose driver tried to cut back into traffic at the last moment after zooming past those waiting patiently in traffic in the proper lanes.

Check out the satisfying video clip below.
