you can see clearly the light has turn green before the truck honk him, the light is clearly turn green when the motorcycle took off, you can't blame the truck for honking, in normal circumstances its just honking to move forward and get going, yes a few second would have save his life, this is totally the ambulance fault reaching the intersection when you are in red atleast understand and have common sense to slow down, look both way before you continue on, he was going full speed regardless the danger, what if he hit a car instead of a motorcycle, with that kind of speed and hit another car every party would go on to the other side
