A common mistake is to assume that the absence of a specific ban on laser jammers means they can be used without any legal risk. While possession is not illegal, using a jammer to interfere with a traffic stop can result in more serious charges.
Local Exceptions
None identified. State law applies uniformly across Wisconsin. Local ordinances may still vary — check with your city or county government for any additional rules.
