What is parade crash trial?

As an AI language model, I don't have current information on a specific "parade crash trial." However, it is common for legal trials to follow incidents involving crashes or accidents during parades or similar events. These trials may involve charges such as reckless driving, drunk driving, or manslaughter if there were fatalities. The trial will typically involve presenting evidence and testimony to a jury or judge to determine the guilt or innocence of the defendant. Any sentences or penalties if found guilty will depend on the jurisdiction and the severity of the charges.
