Are Police Scanners Legal in Ohio?

Police scanners have become more accessible than ever, from handheld radios to smartphone apps that stream live public safety communications. Because these tools are easy to obtain, many Ohio residents question whether listening to police radio traffic is allowed under state law. The short answer is that scanner use is often lawful, but certain circumstances can turn a legal device into the basis for criminal charges.

Knowing how Ohio law treats police scanners can help you avoid unintended legal trouble, especially if a scanner is discovered during a traffic stop or criminal investigation.

What Is a Police Scanner?

A police scanner is a device that receives radio frequencies used by law enforcement, fire departments, and emergency medical services. Traditional scanners are standalone radios, while newer options include mobile applications that rebroadcast publicly available radio traffic.

These devices are commonly used by hobbyists, journalists, and community members who want real-time information about emergencies. Problems typically arise not from what a scanner is, but from how it is used.

Ohio law does not prohibit the general ownership of police scanners. Individuals may buy, possess, and use scanners for lawful purposes, and there is no blanket state-level ban on these devices.

However, scanner legality is closely tied to intent. Ownership alone is rarely an issue, but using a scanner in connection with criminal activity can create serious legal consequences.

When Does Using a Police Scanner Become Illegal?

Under Ohio Revised Code § 2923.24, it is unlawful to use a criminal tool, such as a police scanner, to assist in the commission of a criminal offense. This includes using scanner information to evade law enforcement, avoid detection, or gain a tactical advantage while committing a crime.

For instance, monitoring police activity to determine when officers are nearby during an illegal act can lead to additional charges. In these cases, prosecutors focus on whether the scanner was used to further criminal conduct, not merely whether it was turned on.

Having a police scanner inside a vehicle is not automatically illegal in Ohio. That said, scanners found in cars are often examined more closely by law enforcement, particularly during traffic stops or investigations involving other suspected offenses.

If officers believe a scanner is being used to aid criminal behavior, the device may support separate charges or be cited as evidence of intent. The surrounding facts and circumstances play a significant role in how the law is applied.

How Police Discover Scanner Use During Investigations

In many cases, scanner-related charges arise after a separate encounter with law enforcement. A scanner may be noticed during a traffic stop, discovered during a lawful search, or revealed through digital evidence on a smartphone.

Officers may look for indicators such as active scanner apps, open radio frequencies, or statements suggesting the device was used to monitor police movements. Understanding how scanner use comes to light can help explain why intent and context are so important under Ohio law.

What Penalties Can Apply for Illegal Scanner Use?

If a police scanner is used to facilitate a crime, penalties depend on the underlying offense involved. The scanner-related charge may be a misdemeanor or a felony and is often added alongside other criminal counts.

Possible consequences include:

  • Fines
  • Jail time
  • Probation
  • Forfeiture of the device

A conviction may also carry long-term effects, such as a permanent criminal record.

What Should I Do if I’m Charged Over a Police Scanner?

A charge involving scanner use does not automatically establish guilt. Prosecutors must prove that the device was used to assist criminal activity, not merely that it was present.

Reviewing the facts surrounding the stop, search, and alleged intent is often critical. Legal challenges may focus on whether law enforcement had sufficient evidence or followed proper procedures.
