Illinois Driving Laws
Here’s information about some Illinois laws and how they can affect teen drivers.
Graduated Driver’s License (GDL) Violations
Traffic violations related to GDL restrictions can range from fines set by the court to suspension or revocation of your driver’s license or driving privileges.
Driving Under the Influence in Illinois
In Illinois, drivers with a blood alcohol concentration of .08 or more can be charged with a Driving Under the Influence (DUI) violation. While the penalties are severe, they’re even more punitive for drivers under the age of 21.
Under 21 DUI
- A first DUI conviction can result in revocation of driving privileges for a minimum of two years.
- A first-time DUI offender under age 18 on a statutory summary suspension is not eligible for a Monitoring Device Driving Permit (MDDP).
Remedial education and/or retesting may be required prior to reinstatement of driving privileges for those under age 18.
Illinois alcohol possession or consumption law
A person under the age of 21 who is found guilty or granted court supervision for a violation of state law or local ordinance relating to illegal consumption, possession, purchase or receipt of alcohol, regardless of whether a vehicle was involved, will face a loss of driving privileges, in addition to any fine imposed.
- Court supervision for any of these offenses can result in a three-month suspension of driving privileges.
- A first conviction can result in a six-month suspension of driving privileges. Subsequent convictions can result in an extended suspension or revocation of driving privileges.
Driver, Passenger and Child Passenger Safety Belt Laws
Here’s a summary of the passenger restraint laws in Illinois:
- Safety belts are required for the driver and front seat passengers age 8 and older. All passengers age 16 and under must be properly restrained regardless of their location in the vehicle.
- If the driver is under age 18, all passengers under 19 must be restrained in all seats.
- Any driver transporting a child under age 8 is responsible for securing the child in an appropriate child restraint system for his or her age and weight.
Children over 40 pounds may be transported in the back seat of a vehicle with only a lap belt if the back seat is not equipped with a lap and shoulder belt.
Failure to comply with these laws can result in fines set by the court and possible suspension of certain driving privileges.
