If you were charged with reckless endangerment after causing a car accident, you first need to understand that this is more than a mere traffic violation. This is a criminal charge.
If your accident happened in Delaware County, you are going to have to go to a preliminary hearing in front of a local district justice and then, if the charges are held over, you are going to have to go before a judge in Media.
I suggest you talk to a local criminal attorney, and by that, I mean somebody who handles a lot of cases in Media.
