Actually, they say that transportation problems cannot be used as a excuse. Florida

But there could always be an exception to these if you can argue hardship as you put forth.

Recently served in Sumter County. One of the first questions they ask upon arrival is "Do you have a current driver's license?" Then, once everyone is seated, and some official comes in and asks, "Is there anyone in here that does not have a valid driver's license?" They also state you are selected from driver's license records, so I wonder how you were you even chosen to appear. And, as others have said, you absolutely cannot take a cell phone into the courthouse. You go through a screening process upon entering the building.
