One of the most severe traffic charges is vehicular manslaughter (C.G.S. §53a-56b). If the driver willfully harms someone with their vehicle and the person dies, they would face much harsher penalties than if they behaved carelessly and mistakenly injured and killed the person. Second-degree manslaughter with a motor vehicle is a Class C felony punishable by up to ten years in jail and a fine of up to $10,000.
