A little help

Never a good thing to witness these types of accidents or situations! Everybody will cope differently. I used to run a 30 t tow truck when I wasn't hauling fluid, have seen many , something you never get used too, just talk to people ,get some help, and use your experience to your advantage,meaning I myself think of it has a reality check (slowing down stay defensive on the road etc,etc),in many ways. All the best to you and condolences to those affected, regards John
