If the police did not have probable cause to arrest you for driving under the influence, your attorney may be able to ask the court to suppress evidence gathered after the arrest, including chemical test results and other evidence obtained as a result of the unlawful arrest. Without that evidence, the state’s case against you can fall apart entirely. If you are facing a DUI charge in 2026 and questioning whether the arrest was legal, the Naperville, IL DUI defense lawyers at Appelman Law LLC can review exactly what happened and fight to protect your rights.
What Is Probable Cause and Why Does It Matter?
Probable cause is the legal standard police must meet before they can arrest someone. It means that based on the facts and circumstances the officer observed, a reasonable person would believe that a crime had been committed. It is a higher bar than just a hunch or a suspicion. But it does not require proof beyond a reasonable doubt.
