Am I entitled to pre-trial discovery for a traffic citation?

Generally, neither party is entitled to pretrial discovery in traffic forfeiture actions. But a defendant has a limited right to inspect and test devices used by the state to determine whether a traffic violation has been committed, including speed and alcohol detection devices. Before these devices can be inspected and tested, a defendant must first request court approval within 10 days after the alleged violation, and a court must order that these devices be inspected and tested. See Wisconsin statute 345.421.

I lost my ticket and forgot the appearance date. What should I do?

Contact the Clerk of Courts in the county where the citation was issued.

I have a perfect driving record but the officer gave me a ticket anyway. Why?

Decisions to cite are situational and circumstantial. The nature of the violation, weather conditions or other factors are considered before issuing a citation. An individual's driving record is typically not a factor.

If I file a complaint against an officer, will the ticket be dropped?

No. While the State Patrol will investigate complaints regarding the conduct of its employees, we believe that the merits of the citation should be assessed by the judiciary.
