I got rear-ended last year in this exact situation on 84. Four cars were involved because traffic came to a stop for construction and the people behind me weren't paying attention. Slammed into me at 65, then i slammed into the car infront of me. The cars on the sides got hit as well. They never even slowed down. Thank goodness I was in a truck, they just ruined the bed of it. My insurance totaled it out.
