It is also illegal for a person under twenty-one to present false identification in an attempt to purchase alcohol. Substantial penalties exist in Illinois for the operation of a motor vehicle by a driver with a blood or breath alcohol concentration of .08 or greater. Arrests are also possible at lower alcohol levels if driving is impaired.
Subsequent offenses entail penalties of significantly greater severity.
Transporting open alcohol containers in a motor vehicle is also punishable under Illinois law. A sentence of life imprisonment can result from a conviction for possession of a controlled substance that results in death or bodily injury.
