What could be the consequences if you are late paying a traffic ticket in Florida?

If you are just late I'd contact the court and make arrangements. Otherwise your drivers license will be suspended for failure to pay fines and an arrest warrant will probably be issued for you. The court may wait very short time (within five days) before give out warrant. The sooner you contact the court, the better change the court will not issued the warrant. Most state can reissued the court date (but must prove why you can not make the last court date). If you are not an Indiana resident, your state of residence will be contacted. You will then have 30(if I remember correctly) days to show your state proof of payment or your license will be suspended.
