Your advice is exactly the same as my daughter and son in law, who is a cop. SOP in any accident like that is transport the person. Can't say I was thinking to clearly. Actually I spoke to my an attorney, who told me to file a complaint to get a record of the event and follow started. However, he also advised me that as both KDOT and the EMS/Sheriff departments are state govt. agencies, 90+% chance the case would get thrown out because it is extremely difficult to sue the State.
Still pursuing this as in trying to find out if the painting had been done by a contractor rather than KDOT, no data yet on that one. My attorney is looking at other possible steps. I will say that 5 days after the event, I had a friend drive me out to the scene and you could still see where the rear tires skidded in all the excess glass powder.
