Need an accident report from PA.

Hello all,

I need some advice. I was involved in a minor scrape (details unimportant) back in Feb. 2011 in Pennsylvania, while driving for May. In my current job search it came up on my DAC as a non-reportable DOT accident. I need to provide a potential employer with a copy of the report to show I wasn't at fault.
Therein lies my problem. I have since lost the copy I had and can't for the life of me recall the city/town it occurred in.
Might someone know how I go about getting a copy with such a vague recollection of the events?

For those dying to know....I was making a left turn on a crowded street...waited for light to turn yellow so as not to cause an accident....meanwhile a woman decides to race the light and gets her mirror clipped off trying to squeeze between my rig and the median. A cop showed up, found no one at fault, and we exchanged insurance info. End of story.
