Can an IL police officer issue tickets outside of their jurisdiction? What the law says
Can an Illinois police officer write you a ticket when they’re outside their primary jurisdiction?
In Illinois, state law allows police officers to conduct investigations and make arrests outside their jurisdiction only in limited situations.
“Law enforcement officers in Illinois can issue tickets outside their jurisdiction, but it’s only under certain circumstances,” Teri Ross, executive director of Illinois Legal Aid Online, told the Belleville News-Democrat in a 2025 interview.
One situation in which an officer can write a ticket elsewhere is if the crime originated in their jurisdiction and then crossed into another, like a speeding driver, for example, Ross said.
Other potential situations would be when there is an immediate threat to public safety or if two municipal governments have a reciprocal agreement saying their officers can assist one another, Ross continued.
Illinois state law says any officer employed by a law enforcement agency within the state can conduct temporary questioning and make arrests in any jurisdiction in the state in limited circumstances, including:
- If the officer is engaged in the investigation of criminal activity that happened in their primary jurisdiction and the temporary questioning or arrest relates to, arises from or is conducted pursuant to that investigation.
- If the on-duty officer becomes personally aware of the immediate commission of a felony or misdemeanor violation of Illinois state law.
- If the on-duty officer is requested by an appropriate state or local law enforcement official to render aid or assistance outside the officer’s primary jurisdiction.
Other situations may apply in which a law enforcement officer may conduct an investigation or make an arrest outside their Illinois jurisdiction.
When an officer from a different jurisdiction makes an arrest, the law enforcement agency in which the arrest was made must be immediately notified, according to the state law.
