Laws and penalties for drunk drivers are different dependent on the age of the driver. Since those under the age of 21 cannot legally drink, the penalties are different.
The Illinois Liquor Control Commission explains the penalties of a DUI for minors.
The zero-tolerance law
In Illinois, there is a zero-tolerance law that states if you drink alcohol, you can lose your license. Minor drivers who have a BAC over 0.0 will face a three-month suspension or a six-month suspension if they refuse alcohol testing. If you offend for a second time, you can lose your license for one year. It is two years when you refuse to take the test.
The offenses and convictions
Prior to arrest, if your BAC is at least .08% or if you refuse to take an alcohol or drug test, you face penalties. Upon the first offense with BAC over the legal limit, you face a six-month suspension. If you refuse testing, it is a one-year suspension.
If an officer pulls you over for a second DUI within five years of the first DUI, the penalty is a license suspension for one year. If you refuse testing, it is three years.
If convicted of a DUI, you could face jail time of up to one year. Also, there are fines up to 2,500 dollars. You will lose your license for two years minimum and you cannot receive any driving relief until the second year.
Upon the second conviction, the jail time and fines stay the same. However, you lose your driver’s license for a minimum of five years or until you reach the age of 21, whichever is the longest. You also have a mandatory five days in jail or 240 hours of community service.
