We responded to an MVA, vehicle off roadway into a tree. I was crew on rescue…squad, captain & engine arrived on scene 1st & rescue was instructed to drive in oncoming lane (two lane country road) & drive up to vehicle involved. vehicle was abandoned & sustained heavy front end damage. Occupants no where to be found. Traffic control was to be handled by squad & engine (no longer needed) while rescue was to disable vehicle battery & wait for tow truck to arrive. Scene was on a down hill curve in a 55mph zone… sheriff’s deputy vehicle was positioned @ top of hill to slow traffic. While rescue crew worked on vehicle & assisted deputy with occupant search, captain & squad crew left there post as traffic control to return to quarters, not notifying the rescue. While on foot approaching the crash site vehicle, I spotted an older Mack truck semi tanker approx 6000gal cap. speeding at us. There was a vehicle in the thru lane with boat-in-tow stopped adjacent to scene effectively blocking the lane. The semi was exceeding the speed limit and unable to stop in time. The trucker switched into our lane, locked his brakes, trailer & all and was heading directly at our crew & vehicle. All I could think of was to yell RUN at the crew & get the heck out of the way! The truck managed to stop less than one foot from our truck & no one was injured. The deputy had a few harsh words with that driver… but I don’t think she got her point across… I was out on another call a week later involving the same driver who overturned a grain rig on a state highway driving too fast. I am not an officer but if i am volunteering my efforts, I demand competence… I too want to return to my family after the call.
Traffic control became a priority on all scenes after that day. Communication is very important.
