Answer:
1. Driving above the speed limit
2. Hit and run
Explanation:
John was speeding, he was moving above the speed limit, crossed the centerline and hit another car into the ditch.
A case can be filed against him for not obeying traffic laws.
The second case could be manslaughter (if the driver in the other car died) or at the very least he could be charged with careless driving, intent to harm or disregard for human life (by fleeing)
