Petition Tired Drivers cause violent deaths & horrific injuries

I would like a debate to raise awareness for the early diagnosis of HGV drivers with sleep apnoea.Last year my son and his fiancee were crashed into by a driver who had undiagnosed sleep apnoea.My son was left with serious brain injuries and his fiancee was killed.The driver was charged with death by dangerous driving but days before the trial the case was dropped by the CPS as he was driving unaware of this medical condition.There are clear criteria and indicators as to who is likely to suffer this condition.Please help raise awareness with haulage employers and GP's.So that no other person is killed by a condition that is treatable.
