Leaving a scene after causing damage to someone’s property without providing any kind of information is considered a hit and run.  Unfortunately, in New York it is not usually the case that someone will leave a note after damaging your car. If you find that your parked car is damaged, you have a choice whether or not to report it to your insurance company

You should call a car crash lawyer if you are injured in an accident.  It might not be clear how serious your injuries are right after an accident, but an experienced car crash attorney can advise you about steps to take to preserve your rights.  For example, a car crash lawyer is likely to suggest that you take the ambulance to the hospital to be checked out - you could be in a state of shock and the injuries might be worse than you think.  A car crash attorney will also suggest that you file for "no-fault benefits" so your medical bills will be paid, because a car crash lawyer knows that the deadlines are short.  A car crash attorney will also recommend how to best handle your property damage claim, should there be damage to a vehicle.
