Carelessness versus criminal negligence
Most accidents are handled through civil claims and insurance rather than criminal court. Criminal negligence in New York is a much higher bar than the ordinary carelessness that supports a lawsuit, and courts look for conduct that is a serious departure from how a reasonable person would act. Some assault provisions reach injuries caused with criminal negligence when a weapon or dangerous instrument is involved, and vehicle cases have provisions of their own. Conduct where a person was aware of the risk and went ahead anyway is treated as recklessness, which is more serious. Whether a charge is brought at all often depends on how serious the injury was and on what investigators learn about warnings or earlier incidents that were ignored.
What to preserve
Photographs of the scene, maintenance and inspection records, training records, and witness names often decide whether conduct looks like an accident or something more. Employers may need to preserve records too, and workplace incidents can also involve OSHA or another regulator. Do not discuss fault with the injured person or their family. Notify your insurer promptly, but speak with counsel before giving a recorded statement, since what you say may be used in more than one proceeding.
Criminal and civil at once
A negligent injury charge often comes with a civil claim, and the two can affect each other. Statements made in one may be used in the other, and a guilty plea can have consequences in the civil case. Insurance coverage may help with the civil claim but generally does not pay for a criminal defense unless the policy says so. In a first meeting we look at the charge, the facts that bear on the degree of carelessness, the available insurance, and any regulatory inquiry that is already underway.
