Making a U-turn seems simple enough — flip the wheel and head the other direction. But in Illinois, the legality of that maneuver depends on where, when, and how safely you execute it. Here's what every Illinois driver should know.
Illinois U-Turn Laws and When They Apply
Illinois does not ban U-turns outright. Under 625 ILCS 5/11-802, a driver may turn to proceed in the opposite direction only if the movement "can be made in safety and without interfering with other traffic."
The statute adds a second restriction. No vehicle may make a U-turn on a curve or near the crest of a hill. It is also prohibited anywhere a driver approaching from either direction cannot see the turning vehicle within 500 feet.
In short, Illinois treats U-turns as legal by default — but with strict conditions. If you cannot complete the turn safely, or if visibility is limited, the turn becomes illegal the moment you start it.
Local municipalities, including Chicago, may impose additional restrictions through posted signs or city ordinances. It is important to check signage before executing a U-turn at any intersection.
Penalties for Making an Illegal U-Turn
Under 625 ILCS 5/16-104, an illegal U-turn is classified as a petty offense for a first or second conviction. That means no jail time, but fines ranging from $75 to $1,000 under 730 ILCS 5/5-4.5-75, plus mandatory court costs. The court may also impose probation or conditional discharge for up to six months.
A third or subsequent illegal U-turn conviction within one year escalates to a Class C misdemeanor. At that point, you face up to 30 days in jail, fines up to $1,500, and up to two years of probation or conditional discharge under 730 ILCS 5/5-4.5-65. More importantly, a Class C misdemeanor is a criminal offense — meaning it creates a permanent criminal record.
Why U-Turn Accidents Are So Dangerous
U-turns force a vehicle to cross multiple lanes of traffic, often at low speed. That mismatch — a slow-turning car meeting fast-moving traffic — creates a high risk of broadside or T-bone collisions.
These crashes tend to produce serious injuries because the struck vehicle's side offers far less protection than its front or rear. Common causes include:
- Misjudging the speed of oncoming vehicles
- Limited visibility on curves or hills
- Failing to check blind spots before turning
Even when a U-turn is technically legal, executing it carelessly can lead to devastating results.
Who Is at Fault in a U-Turn Crash
In most U-turn accidents, the turning driver bears significant fault. Illinois law places the burden on that driver to confirm the maneuver is safe before starting it.
However, Illinois follows a modified comparative negligence standard. If the other driver was speeding or distracted, they may share a portion of the blame. Fault is rarely black and white, which is why evidence — dashcam footage, witness statements, police reports — matters so much in these cases.
