I recently contested a ticket and the court proceeding was over Zoom. This was as of August.

I was one of the last people in the docket so got to see a lot of other people's cases. Something like this, where there was a legitimate issue with the signage, the judge would throw out entirely.

Look at the picture the meter reader took (you should be able to view this online - check the instructions on the ticket) and it might show the sign, depending where your car was. If you contest the ticket, there's an opportunity to upload a picture, where you can put this photo too. The judge will look at the picture the meter reader sent along with any pictures you present.

Since there obviously is a sign, and it says something about parking, I can't say for certain that yours will definitely get thrown out. But the judge definitely did not like Baltimore City's parking enforcement and threw out a lot of tickets.

Basically anything that didn't have a legit excuse was reduced to $50 total with absolutely any excuse, including "oops, I didn't mean to". (Which was mine, TBF.) (Except handicapped parking issues because those are way more expensive.)
