The answer is yes.

Recent U.S. and Illinois Supreme Court cases have held that a request for a driver’s license is reasonable regardless of the reason for the stop.

Before 2005, police could not change the nature of a traffic stop without articulating specific facts to support the change. For example, an officer could not stop you for running a red light and then bring in the canine unit to sniff your car for drugs without having a reasonable basis to believe you had drugs. After the U.S. Supreme Court decision in Illinois v Caballes, however, an officer can change the reason for the stop as long as the stop is not unduly prolonged. In other words, the officer cannot make you wait around for the dogs long after the officer has completed paperwork for the stop.

In People v Cummings, the question was whether the officer unduly prolonged a stop by asking for a driver’s license after the original reason for the stop had vanished. (In this case, the police were looking for a woman with an outstanding warrant and the driver turned out to be a man.) An interest in officer safety entitles the officer to know whom he is dealing with. The stop, however, must be lawfully made–the officer must still have probable cause to stop you.

If you are charged with DUI or another offense, contact an experienced attorney immediately. An attorney may review your case for your best possible defense. If the police acted improperly, the attorney may be able to petition the court to suppress the evidence from any search. Even if this is not possible and the evidence against you is overwhelming, an attorney who is respected in the courthouse may be able to negotiate a more favorable plea agreement than you could on your own.
