How far do you want to go allowing the Govt to prosecute people for accidents?
Unfortunately there would have to be common sense used in the decision making process.
I know of several cases where there should have been much more severe penalties than what was imposed.
In one case a couple I was acquainted with were kill when the motorcycle they were riding on was struck by a large tractor that came off a trailer in a curve. The driver pulling the trailer was cited for an unsecured load. No charges related to the deaths. He was a "poor farmer" just trying to make a living, didn't have anything worth taking in a law suit.
Another was a dump truck driver that was talking on his phone when he ran down the biker that had slowed to turn into his driveway, the bikers kids got to see daddy shredded by the truck. Failure to yield, no loss of license.
Pretty much unless there is alcohol involved there won't be any serious penalties in Oklahoma
