Final answer:
If you don't respond to a ticket you've received, you may face penalties and serious consequences.
Step-by-step explanation:
If you don't respond to a ticket you've received, it will depend on the context of the ticket. In legal terms, a ticket can refer to various things such as a traffic ticket, a citation, or a summons. If you don't respond to a traffic ticket, for example, you may incur penalties such as fines, points on your driving record, or even a suspension of your driver's license. If you don't respond to a citation or a summons, you may face more serious consequences such as a warrant for your arrest or a default judgment in a civil case.
