Overview of Speed Limits

The City of Sioux Falls sets local traffic regulations; posted speed limits and municipal code provisions govern driving on city streets. Where local limits are not posted, statutory default limits apply or as otherwise posted by the city. For full ordinance language see the municipal code linked below City Code - Traffic[1].

Always observe posted speed signs—they control on the street even if a general limit exists.

Penalties & Enforcement

Traffic enforcement in Sioux Falls is carried out by the Sioux Falls Police Department and citations are processed through Sioux Falls Municipal Court or by referral to state courts for violations governed by state law. Fines, suspensions, and other sanctions depend on whether the offense is a city ordinance or a state statute. Municipal Court[3]

  • Monetary fines: specific fine amounts for many city traffic ordinance violations are listed in the municipal code or the court fine schedule; if a numeric amount is not on the cited page, it is "not specified on the cited page" and you should consult the court for the current schedule.
  • Escalation: first, repeat, and continuing offense procedures vary by ordinance; specific escalation ranges are not specified on the cited municipal-code page.
  • Non-monetary sanctions: state DUI statutes authorize license suspension, possible jail time, and mandatory assessments; municipal sanctions may include court orders or compliance directives depending on the charge. See state DUI statute for statutory penalties SDCL - DUI[2].
  • Enforcer & reporting: primary enforcement is by the Sioux Falls Police Department; to report unsafe driving or file a complaint contact the Police Department or submit documentation to Municipal Court or the Traffic Division.
  • Appeals & review: citations issued within Sioux Falls are typically contested in Municipal Court; appeal time limits and procedures are set by the court rules—check the Municipal Court page for filing deadlines and forms.
  • Defences and discretion: law enforcement and the court may consider defenses such as necessity, emergency, or mistaken identity; permit or variance processes for special events are managed by city permitting offices and are separate from traffic adjudication.
If a statutory penalty amount is needed for a DUI charge, consult the state statute directly because municipal pages may not list state-imposed sanctions.
