Illinois Appellate Court
Criminal Court
Probable Cause
Deputy's testimony that he observed Defendant's right-side tires cross over fog line twice for a couple of seconds each time while following him, was sufficient, if believed, for deputy to believe that Defendant violated improper-lane-usage statute and to provide him with probable cause to effect initial traffic stop. Evidence of endangerment in violation of improper-lane-usage statute is not essential to finding of probable cause for stop. (WELCH and CHAPMAN, concurring.)
