Tori Bedford at WGBH reports from Market and North Beacon streets shortly before midnight:
It appears part of a truck came off and fell on to an SUV - right through the drivers side window. EMTs are attempting to get the driver out and help another man who is lying on the sidewalk
The trailer has a large NESN logo on the side.
It seems like everyone is responsive at least - including the driver.
Firefighters extricated the driver around 12:05 a.m.
