People v. Hackett

Hackett was charged with aggravated driving under the influence of alcohol, 625 ILCS 5/11-501(a)(2), (d)(1)(A), and aggravated driving while license revoked, 625 ILCS 5/6-303(d-3). He moved to quash arrest and suppress evidence, arguing that the arresting officer lacked probable cause to stop his vehicle so that evidence gathered after the improper stop constituted fruit of an unlawful search. The stated basis for the stop was improper lane usage. The trial court granted defendant’s motion, finding that momentary crossings of a highway lane line did not give the officer reasonable grounds to make the stop. The appellate court affirmed. The Illinois Supreme Court reversed and remanded. To establish probable cause that a violation of the lane usage statute has occurred, the officer must point to facts which support a reasonable belief that defendant has deviated from his established lane of travel and that it was “practicable” for him to have remained constant in his proper lane. A traffic stop may be justified on something less than probable cause. Here, a police officer observes multiple lane deviations, for no obvious reason; an investigatory stop was proper.
