I got a ticket for no plates on my trailer and when I went to pay it online it said there was a criminal summons issued Will I go to jail if I get pulled over now

Did you miss some kind of court date or time limit to correct the problem? If so a warrant would have been issued if you were a no show.

Some "tickets" can not just be paid but require that you appear, But agree, did you not pay it on time, and if not paid, did you fail to appear on the date on the ticket

The tickets is a few months old it was for my atv trailer without plates in a state park. Is the criminal summons the same as a warrant

Yes. It is stating that there are charges against you and your wanted. Was it an actual state park or was it a federal park under state and federal control?

It is a state park st joes in mo. I was thanking that the criminal summons was another court date that I would get in person or in the mail

You should have received something already. Usually your given time like 2 or 3 weeks to correct a problem or you show up in court and explain why. When you don't show then that's when they issue a warrant for your arrest. You need to examine the original ticket to see what is going on.
