Those who are arrested for DUI in Illinois are subject to detention until a cash bond is posted. The purpose of the bond is to ensure the defendant’s return to court. If the defendant fails to appear at any court date, the cash bond will be forfeited and the judge will thereafter issue an arrest warrant.
The sheriff may make an active effort to locate the defendant. Even short of that, the defendant is subject to arrest at any time thereafter in the event he or she has future contact with the police.
Even if the initial purpose of the contact is not related to serving the warrant, if the police run a warrant check upon contact, something they ordinarily do, the defendant will be taken to jail as a result of the active warrant, since a warrant is a court order. There is no statute of limitations for a warrant and no jurisdictional restriction. In other words, a person who has an active warrant can be hauled to jail at any time and from anywhere in the country until the warrant is served or a judge quashes it.
