Dashcam footage released by the New Jersey Department of Transportation (NJDOT) on March 20 shows the moment a semi-truck collided at high speed with three New Jersey State Police vehicles on Interstate 80 in the early hours of February 24.“This is a heart-stopping reminder of why motorists need to slow down and move over for first responders,” NJDOT wrote on Twitter. “Thankfully, no one was injured this time!” they added.
