When teens get behind the wheel of a car after they have consumed alcohol, they have a higher chance of getting into an accident. According to the National Highway Traffic Safety Administration (NHTSA), car crashes are the leading cause of death for teenagers, with a fourth of those crashes involving an underage driver who has been drinking. The NHTSA reports that drivers between the ages of 16 and 24 made up 39 percent of drivers involved in fatal alcohol-involved crashes. Illinois has adopted a zero tolerance law, meaning that if an underage driver is found to have any alcohol in their system, they will lose their driving privileges. Being charged with an underage DUI is a serious offense, so it is important that you understand the penalties.

Legal Penalties for Underage Drinkers

Under the Zero Tolerance law in Illinois, an underage driver who is found to have alcohol in their system can be subject to penalties under the Zero Tolerance law, but also DUI laws.

Alcohol is not a new invention--National Geographic states that the Chinese were making a type of alcohol as long as 9,000 years ago. Humans have loved alcoholic beverages for thousands of years, and while the beverages themselves have been refined and the way humans use alcohol has changed, such as the prevalence of DUI’s, the effects that it has on us has not changed. Here are five interesting facts about alcohol and the human body:

1. Moderate Drinking Can Be Good for Your Health

A study that was recently concluded at the University of Sao Palo’s Biomedical Science Institute in Brazil has finally pinpointed the enzyme that allows moderate alcohol use to benefit your heart. Scientists have proposed that alcohol has certain health benefits for years, but now the specific reason why has been discovered. The study showed that when alcohol is consumed in moderate amounts, it can help rid the body of aldehyde, which is a toxic byproduct of alcohol digestion, but also a byproduct of stressed heart cells, such as those from a heart attack.

Despite a decades-long "war" on drugs in the U.S., drugs continue to be an issue that plague our streets and our highways. According to the National Council on Alcoholism and Drug Dependence (NCADD), more than 15 percent of nighttime, weekend drivers tested positive for illegal, prescription, or OTV medications. More than 10 percent tested positive for illegal drugs. Of fatally injured drivers in 2009, nearly 20 percent tested positive for at least one type of drug at the time of death. The number of people who died as a result of a drugged driver is even more sobering: nearly 4,000 drivers who were killed in 2009 were on drugs.

The issue of drugged driving continues to lag statistically behind driving under the influence of alcohol, but this could change as more states move toward relaxed legal policies regarding drug use and legalize marijuana. A number of states, including Illinois, have introduced per-se laws in an attempt to quantify and punish drugged drivers. Reported by StopDruggedDriving.org, the Obama Administration has pinpointed per-se laws as a major initiative. StopDruggedDriving.com reports that, "per-se means that any detectable amount of a controlled substance, other than a medicine prescribed by a physician for that driver in a driver’s body fluids, constitutes per se evidence of a ‘drugged driving’ violation."

Per-se laws, of course, are problematic. Many drugs, including marijuana, which is now legal for recreational use in two states, tend to stay in a person’s system long after the effects of the drug have worn off. This ostensibly means that a person could legally buy and smoke marijuana in Colorado, drive back to Illinois three days later, and be arrested for drugged driving while on the way to work.
