University of Massachusetts at Amherst police issue more traffic violations than most municipal departments

Drivers who are stopped by a police cruiser in Massachusetts might expect either a state trooper or a local city or town officer to walk up to their car window.

But there are a number of less-traditional law enforcement agencies scattered around the state, and some of them are more active in doling out traffic violations than you might expect.

The University of Massachusetts Police Department in Amherst issued more violations than most municipal departments from 2010 through 2015, state records show.
