“The driver of the other vehicle was ticketed for careless driving with serious bodily injury, according to the police report.”
Was he actually ticketed for drunk driving? Should be attempted manslaughter.
They could get a BAC on the perp pretty quick. If the perp was high, might take longer for the test/s to come back. Since the perp hasn’t been charged yet, either the results haven’t come back, the perp has some juice, or the perp is in the wind.
