🚨 Improper lane usage (625 ILCS 5/11-709) is the "small" ticket behind a huge share of Will County DUI arrests — and it is often the weakest link in the State's case. Illinois law requires a vehicle to be driven "as nearly as practicable entirely within a single lane" and not moved from that lane until the driver has first made sure the move can be made safely (625 ILCS 5/11-709(a)). Standing alone, it is a petty offense punishable by a fine of up to $1,000 plus court costs (625 ILCS 5/16-104) — no jail. But a conviction is a moving violation on your Secretary of State record: three moving-violation convictions in any 12 months trigger a license suspension for drivers 21 and over, and just two in 24 months do it for drivers under 21 (625 ILCS 5/6-206(a)(2)). Court supervision keeps it off your record as a conviction, but supervision is not automatic. The bigger issue is what the ticket unlocks. In People v. Hackett, 2012 IL 111781, the Illinois Supreme Court held that an officer who sees a car drift over the lane line for no apparent reason has reasonable suspicion to stop it — even if the drift was brief and no one was endangered. That stop is the doorway to the odor-of-alcohol question, field sobriety tests, a breath test, and a DUI charge under 625 ILCS 5/11-501. The flip side: if the dashcam shows no lane deviation, or a deviation that was "practicable" (a pothole, debris, a cyclist, a wide truck), the stop was unlawful — and a Motion to Quash Arrest and Suppress Evidence can throw out everything that followed, including the DUI. Squad-car video is the first thing to demand. 💡 Jack L. Zaremba is a former Will County prosecutor who knows how officers build a lane-usage stop into a DUI case. With over 20 years of legal experience, he challenges the stop itself — not just the charge.
