How Long Can Police Detain Me During a DUI Stop in Chicago?

Chicago DUI Defense Lawyer

If you’ve been stopped by police in Chicago under suspicion of driving under the influence (DUI), one of the first things that may come to mind is how long you can be detained. Understanding your rights and the length of time police can legally keep you during a DUI stop is crucial. A DUI stop is a serious matter, and knowing the law surrounding it can help ensure you don’t accidentally waive any rights or agree to actions that could hurt your case.

When a police officer pulls you over for suspected DUI in Chicago, they do not have unlimited time to detain you without cause. However, the rules around this detention are nuanced, and the length of time can vary depending on several factors. Understanding the law in Illinois regarding DUI stops and detentions can make all the difference in protecting your rights.


Under Illinois law, a DUI stop is governed by a combination of constitutional rights and state traffic laws. The Fourth Amendment of the U.S. Constitution protects citizens against unreasonable searches and seizures, including unlawful detentions. This means police must have a reasonable suspicion that a crime has occurred or is in progress in order to detain you.

In the case of a DUI stop, officers must have more than just a “hunch.” They must have probable cause or reasonable suspicion that you are operating a vehicle under the influence of alcohol, drugs, or other impairing substances. The most common reason for a DUI stop is the observation of signs of impairment—such as erratic driving, swerving, or failing to obey traffic signals.


The Timeline of a DUI Stop in Chicago

When you’re pulled over for a DUI stop, Illinois law allows officers a certain amount of time to conduct their investigation. While the stop itself is considered a “brief detention,” officers cannot keep you indefinitely without justifiable cause. The general expectation is that the stop will be as brief as necessary to accomplish its purpose—either issuing a citation or making an arrest if there is probable cause.

Typically, during a DUI stop, the officer will ask for your license and registration and may inquire about where you’ve been or if you’ve been drinking. At this point, if the officer suspects DUI, they may ask you to step out of the vehicle to perform field sobriety tests or submit to a breathalyzer test. If the officer does not have enough evidence to proceed with a DUI arrest, they are legally obligated to allow you to leave after completing the initial investigation.

However, if probable cause exists—such as failing the sobriety tests or showing signs of intoxication—then your detention may extend into an arrest. Under these circumstances, the detention is no longer brief and transforms into an arrest with specific legal consequences and timelines.


Illinois Statutes and DUI Arrests: How Long Is Too Long?

In Illinois, there are clear legal guidelines that govern how long officers can detain someone during a DUI stop. The stop is expected to be no longer than necessary to address the reason for the stop. If the officer suspects DUI based on their observations, they can detain you for a reasonable period to conduct further investigation, which includes performing sobriety tests or administering a breathalyzer test.

Once you are asked to submit to a breathalyzer test, Illinois law requires you to comply under the Implied Consent Law(625 ILCS 5/11-501.1). However, you are not legally required to perform field sobriety tests, and refusal to do so cannot be used against you in court. Refusing a breathalyzer test, however, can result in immediate penalties, including a suspension of your driver’s license.

The Illinois courts have ruled that the detention during a DUI stop must be reasonable in duration. This means that while police are allowed to keep you long enough to perform sobriety tests and evaluate your condition, they cannot detain you indefinitely without making an arrest. If you are kept for an unreasonable amount of time, it may be considered a violation of your Fourth Amendment rights.


The DUI Arrest Process and What Comes Next

If the officer determines there is probable cause to arrest you for DUI after their investigation, you will be placed under arrest. This is where the process becomes more formal. Once arrested, you will be read your Miranda rights, and the officer may take you to the police station or a testing facility for further chemical testing.

At this point, the officer must comply with the Illinois DUI law, which allows for chemical tests to be conducted to determine your blood alcohol content (BAC) or to test for the presence of drugs in your system. In most DUI cases, the detention will extend through the arrest and to the processing stages.

It’s important to understand that while you are no longer “detained” in the traditional sense, you now enter a formal legal process that can involve criminal charges. Depending on the outcome of your BAC test or drug test, you may face charges under Illinois law for DUI. These charges can result in significant penalties, including fines, license suspension, mandatory DUI education, and even jail time.


Why You Need a Criminal Defense Attorney During a DUI Stop

The legal implications of a DUI stop can be far-reaching, and the process is not always as straightforward as it may seem. An experienced criminal defense attorney can help protect your rights from the moment you are detained by law enforcement. An attorney can evaluate whether the police had reasonable suspicion to stop you and if the detention was unlawful in any way.

In addition, a skilled DUI attorney can challenge the validity of the sobriety tests, the breathalyzer results, and the circumstances surrounding your arrest. For example, if you were detained for an unreasonable amount of time, or if the officers violated your constitutional rights in any way, your attorney can file motions to suppress evidence or seek a dismissal of charges.

An attorney also helps you understand the potential consequences you face, including the likelihood of a conviction, possible defenses, and the range of penalties available. With a defense lawyer by your side, you will have someone who is looking out for your best interests at every step of the process—from pretrial motions to negotiating with the prosecution and representing you in court.

Frequently Asked Questions About DUI Stops in Chicago

Can I be detained without being arrested?
Yes, during a DUI stop, police can detain you long enough to ask for your license, registration, and perform field sobriety tests if they have reasonable suspicion. However, once they’ve determined there is no probable cause to arrest, you must be allowed to leave.

How long can I be detained during a DUI stop?
The stop should only last as long as necessary to address the suspicion of DUI, typically a short time. If the officer does not have probable cause to arrest, they are required to release you after conducting their investigation.

Do I have to perform field sobriety tests?
No, Illinois law does not require you to perform field sobriety tests, although refusal may raise suspicion and be used against you. However, refusal to take a breathalyzer can result in automatic penalties.
