Understanding DUI Stops in the City of Chicago
Chicago is one of the most heavily policed metropolitan areas in the country. With an expansive network of streets, highways, and expressways, police traffic enforcement plays a significant role in law enforcement efforts across the city. DUI arrests are common in Chicago, particularly on weekends, holidays, and late at night when officers are more likely to suspect impaired driving. In Illinois, especially in a city as active as Chicago, DUI enforcement is strict—but it is also governed by constitutional safeguards that limit how and when police can stop drivers.
Many individuals charged with DUI in Chicago ask whether officers needed probable cause to pull them over in the first place. This question is critical. While officers do not need probable cause to initiate a traffic stop, they must have what’s known as “reasonable suspicion” that a traffic violation or crime has occurred. The distinction between reasonable suspicion and probable cause often becomes a pivotal issue in DUI cases.
