Driving while under the influence (DUI) of alcohol or drugs is obviously illegal in Illinois and throughout the United States. Driving under the influence of illegal drugs is always against the law, but when it comes to alcohol, there is some wiggle room in that it is only technically against the law in situations where the legal blood alcohol limit has been reached or exceeded. The legal blood alcohol content (BAC) limit in Illinois is 0.08. If you have a BAC of 0.08 or more, you cannot legally drive.
None of this should come as a surprise to any person who is licensed to operate a vehicle on Illinois roads. What may come as a surprise, however, is if you encounter a DUI checkpoint while driving. This may be a stressful situation, especially if you have imbibed an alcoholic beverage or two and are concerned that you may have hit that legal limit. Your instinct may be to try to avoid the DUI checkpoint at all costs, whether by pulling a U-turn and driving away from it or by refusing to submit to the DUI testing at the checkpoint.
But are DUI checkpoints even permissible under Illinois law? And are you allowed to legally refuse to submit to DUI testing at a checkpoint? In Illinois, you must stop at DUI checkpoints but can refuse to answer extra questions or perform sobriety tests, though this may result in further investigation or consequences.
Are DUI Checkpoints Legal in Illinois?
In Illinois, DUI checkpoints are used to deter impaired driving and increase road safety. The legality and specifics of these checkpoints are guided by both state and federal laws, which aim to balance public safety with individual rights. If you're pulled over at a DUI checkpoint in Illinois, understanding your rights and obligations is important to help you navigate the situation as successfully as possible.
According to Illinois state law and public policy, DUI checkpoints are perfectly legal and are in fairly common use across the state. The specific statute which provides the authority to conduct DUI checkpoints and sobriety tests is found in the Illinois Compiled Statutes under 625 ILCS 5/11-501. This statute explains the laws governing DUIs and how they may be enforced.
What is the Legal Basis for DUI Checkpoints in Illinois?
DUI checkpoints in Illinois are permitted under the U.S. Constitution and Illinois state law. However, they must meet certain criteria. The checkpoints must be in line with guidelines established by the Illinois Supreme Court and the U.S. Supreme Court. The point is to ensure they do not violate constitutional protections in the Fourth Amendment against unreasonable searches and seizures.
Are You Allowed to Refuse to Participate in a DUI Checkpoint?
First of all, you must comply with the checkpoint procedures. Though you cannot refuse to stop at a DUI checkpoint, you do have the right to refuse to answer questions beyond what is needed to verify information such as your driver's license, registration, and proof of insurance. If an officer has a reasonable suspicion of impairment, they may conduct further tests or ask more questions, but you are not legally obligated to answer them.
Another thing to keep in mind is field sobriety tests. Field sobriety tests may include an officer asking you to walk a few steps forward in a straight line and check for whether you are stumbling (they should also ask you if you have any physical or medical conditions that may prevent you from being able to complete such a test). Another field sobriety test you may be asked to perform is saying the alphabet or counting backward. And, very commonly, you may be asked to do a horizontal gaze nystagmus test, which is when an officer shines a flashlight into your eyes, moves it side to side, and asks you to follow the light with your eyeballs without moving your head as you do so.
You are not legally required to perform field sobriety tests. If asked to take these tests, you can decline. However, a very important thing to know is that a refusal may be interpreted as a sign of impairment (sort of like an admission of guilt, though it technically and legally is not an admission of guilt to refuse) and could lead to further investigation or arrest. And, if you refuse to perform field sobriety tests, you may end up with what is known as a "summary suspension" of your driver's license. This basically means that your driver's license is automatically suspended from a certain date going forward unless you get it rescinded with an official hearing in traffic court.
The more invasive and serious determinant of your sobriety is a breathalyzer test. In Illinois, if you are arrested for DUI, you are required to submit to some kind of chemical testing (which can include breath, blood, or urine) under the implied consent law (meaning that Illinois law views you as having a driver's license as an implied consent to adhere to all traffic rules and undergo sobriety testing). Refusal to take these tests after arrest can result in automatic driver's license suspension, such as the summary suspension described above, as well as other legal consequences. However, at the checkpoint stage, you are not required to submit to a breathalyzer test until after an arrest has been made.
Important Considerations
It is important to keep safety in mind and cooperate with the police. While you have rights during a DUI checkpoint, cooperation with law enforcement can prevent escalation, which, as we know, can increase your legal troubles and even cause a dangerous situation for all involved. It is usually advisable to comply with the basic checkpoint procedures and avoid confrontation.
Something to consider is seeking out some legal advice. If you are uncertain about your rights or how to handle a checkpoint situation, it is advisable to consult with an attorney who can provide the correct and necessary guidance which is specific to your case and ensure you understand the legal implications.
Conclusion
In conclusion, though you cannot refuse to stop at a DUI checkpoint in Illinois, you do have the right to refuse to answer additional questions or perform field sobriety tests. This may have legal consequences, though. Compliance with the checkpoint's basic procedures is required, but knowing your rights and seeking legal counsel if needed can help you manage the situation most successfully.
