7 Illinois Teen-Driving Rules That Surprise Parents

In Illinois, the passengers in your teen’s car can commit an offense.

Parents of new drivers run into rules like that only after the keys change hands.

Here are the Illinois teen-driving rules that surprise parents.

Note: This is general information, not legal advice. Licensing rules are subject to change, so confirm the current requirements with the Illinois Secretary of State.

1. Curfew Until Age 18

Illinois’s teen-driving curfew runs until your teen turns 18.

Your teen’s license is invalid from 10 p.m. to 6 a.m. Sunday through Thursday nights, and from 11 p.m. to 6 a.m. on Friday and Saturday nights.

An instruction permit follows the same overnight hours.

A Friday night game that ends at 10:30 leaves your teen 30 minutes to get home.

A Thursday game that ends at 10:30 is already past curfew, unless one of the exceptions below applies.

2. 50 Hours Behind the Wheel

An Illinois teen driver can’t get a graduated license until a parent, guardian or other responsible adult certifies at least 50 hours of practice driving.

At least 10 of those hours have to happen at night.

Your teen also has to pass an approved driver education course before getting that license.

At an hour a day, your teen needs about seven weeks to reach 50 hours.

The sign-off comes from you or another responsible adult, and a written log of each drive makes it easier.

3. One Passenger Under 20

Your teen’s Illinois graduated license allows one passenger under 20 for the first 12 months, or until your teen turns 18, whichever comes first.

That means your teen can’t drive three teammates home from practice.

Siblings, stepsiblings and the driver’s children and stepchildren don’t count toward the limit.

So your teen can drive a sister and one friend, but a sister and two friends put the car over the limit.

Until your teen turns 18, the front seat is limited to one passenger.

Back-seat riders also can’t outnumber the available seat belts.

4. Passenger Offenses

Riders in a teen driver’s car can commit an offense in Illinois.

That applies to a passenger who’s 15 or older but under 20.

It covers riding with a graduated license holder who’s still bound by the passenger limit, when another passenger under 20 is also in the car.

The driver’s siblings and children don’t count.

If your teen is the driver, tell their friends about the rule before the first carpool.

If your teen is the rider, the same offense can apply to your teen.

5. Phone Ban Under Age 19

Your teen can't use a wireless phone while driving on an Illinois instruction permit or graduated license before turning 19.

The exception covers emergencies, including a call to a law enforcement agency, health care provider, fire department or other emergency services agency.

Drivers 19 and older can generally talk in hands-free mode, but hands-free isn't an exception under 19.

6. Supervising Adult's Age

A teen on an Illinois instruction permit has to practice beside an adult who's 21 or older.

The supervisor has to be a parent, legal guardian, family member or someone standing in a parent's place.

That person also needs the right license class and at least one year of driving experience.

Your 20-year-old home from college can't supervise a younger sibling's practice drive, but a 22-year-old cousin with the right license and a year of driving experience can.

7. Restrictions Past Age 18

Illinois's teen-driving restrictions don't always end on the 18th birthday.

Say your teen commits a moving violation in the six months before turning 18.

If a conviction follows, the curfew, the seat limits and the phone ban keep applying after the birthday.

The restrictions stay in place until six consecutive months pass without an additional violation.

That means a moving violation at 17 and a half can leave your teen under the curfew after turning 18.

Phone Rules for Every Driver

Teen drivers aren't the only ones with phone rules in Illinois.

The state bars every driver, you included, from using a hand-held phone while driving, though exceptions include hands-free mode.

Fines run up to $75 for a first offense and $150 for a fourth offense or later.

Drivers of any age also can't use a wireless phone in a school speed zone, in a construction or maintenance speed zone, or within 500 feet of an emergency scene.

Voice-operated mode is one of several exemptions in those zones, so you can still take a call that way.

Pressing a single button to start or end a call is another.

A Pending Suspension Bill

A House bill filed in January 2026 would add a penalty to the teen-driving passenger limit that applies to your teen.

The version adopted in committee would suspend a graduated license for six months.

That would apply to a passenger-limit violation that causes bodily harm or permanent disability to another person.

That version would take effect January 1, 2027.

As of mid-October 2026, the General Assembly's bill status page showed no action after March 26, 2026.

You can check that page for any later action.

A Canceled License

A teen driver's license or permit can be canceled outright in Illinois.

The Secretary of State must cancel the license or permit of a driver under 18 who's convicted under the state's cannabis, controlled substances or methamphetamine laws.

The offense has to happen while the driver is in actual physical control of a motor vehicle.
