Kent police took him and me and sue without notifying the doctor.
Was he not taken to hospital by ambulance Del and seen by doctors as soon as he arrived? :-/ :-/
Nope, me and Sue took him, they wanted him to stay at the school 
Well that is most odd!!

With a RTC, involving a minor who has been injured he should have had an ambulance summoned so paramedics could check him out at the scene of the accident. This is vital so as to rule out neck, back or any other potentially serious injuries. Did your son leave the scene before the police arrived? Did not the Transport Police advice him to stay and wait for medical attention?
There are some important questions to be asked here Del.

They never gave him any medical attention at all, nor did the teachers, they asked what injuries he had that was it. School then walked him to reception he was walking fine on his own, but that isn't the point. The police never came to the school they wanted us to wait there for them, then Sue took him to the hospital, I met her at the school first to check he was ok. No ambulance was even mentioned, probably because he was walking around but thats the adrenaline from the shock. He is only 15 too.
It sounds to me Del that he did not stay at the scene of the accident and therefore did not receive the usual police and ambulance service treatment.
It would also appear that the school subsequently failed in their duty of care to ensure he received medical attention as the shock alone, let alone other hidden injuries, can be fatal.
I would certainly be asking some serious questions of the school, and with a RTC involved all his treatment should have been fully undertaken by medical staff immediately following it.
Your son, as you know, made a very bad error in running across a road, then, no doubt in shock, running away from the scene to school. He must understand he should take responsibility for his actions.
However, on an adult level if I was you Del I would be asking to see the full police report on this RTC to ascertain what
actually happened, what police investigation was undertaken, and what is / was the police conclusion. A trip to Ashford police station would be my first point of call. To me there seems to be vital gaps in this story, probably down to the actions, shock and natural fear after the event of a 15 year old, which cannot be blamed on the police or the school.
It all seems like a genuine error by your son that caused the RTC, but how it was all followed up I think needs your attention so you can understand fully what transpired.
