Summarize this article:

Sometimes people can be completely unaware that they have a warrant out for their arrest. Knowing when the warrant was issued could shed light on some important details.  There may be fines associated with your charge that have been accumulating since the warrant was issued. These will be listed among the warrant information. If the warrant was issued a long time ago, you’ll want to get the matter settled quickly before incurring any further penalties. Additionally, in some case, if the warrant was issued long ago, a person cannot be prosecuted for the crime. It is not that the warrant has expired, but some crimes have a limited statute of limitations (period in which the suspect can be prosecuted). Therefore, if you believe that you may have a warrant out for your arrest for an underlying incident that occurred over 2 years ago, look up the charge that would appear on the warrant (or something similar) to see if there is a limit on the time that the warrant would be valid. If you know what you’re being charged with, you can more adequately prepare your response. Vital information includes the date of offense, the details of the charges, and the case type (e.g., felony, misdemeanor, traffic ticket, etc.).  You may be able to avoid being arrested by paying a fine. The severity of your charge may influence your choice of legal representation. Also note any date of conviction, sentencing, disposition, and probation, if they apply to your case. If you’re concerned that you will go to jail, knowing the predetermined bail amount for your charge could help you raise the funds to avoid jail time while awaiting your trial.

Summary:
Find out when the warrant was issued. Inquire about the charges. Note the bail amount.
