I find that unlikely. Charges? None of us have any idea without all the facts. I am curious as to what he would be charged with. If I came upon an MVA like that with civilian car and driver, there would be no charges unless they were intoxicated. Charging people for motor vehicle accidents is a dangerous road to go down outside of mitigating circumstances such as impairment.
On to his civil liability, there will be repercussions for sure. For the agency as well. That is what insurance is for.
