A Massachusetts man was killed on Tuesday afternoon when his Mercedes-Benz Sprinter van failed to observe traffic was slowing down to a standstill and struck the rear of a 2020 Freightliner tractor-trailer on Interstate 84 westbound near exit 28 in the Town of Montgomery.

State Police said Kevin Cantwell, 71, of Shrewsbury, Massachusetts was pronounced dead at the scene. Crash between van and tractor-trailer claims one life

Because the bottom of a truck is higher than the bumper of passenger vehicles, when there is a collision the smaller vehicle easily slides under the truck and the first point of impact is the windshield. Seatbelts, airbags, and car crumple zones do not function as intended in underride crashes —front, side, and rear — leaving passenger vehicle occupants vulnerable to life-threatening injuries.

Note: In order to raise awareness and preserve the memories of underride victims — precious ones gone too soon — I have been writing memorial posts on what could potentially be underride crashes. I am not a crash reconstructionist, and I do not have all the facts on these crashes; but underride should be investigated as a potential factor in truck crash injuries and deaths.
