Iowa 511 is the Iowa Department of Transportation's (DOT) official traffic and traveler information app. The Iowa 511 app provides statewide up-to-date traffic information for interstates, U.S. routes and state highways in Iowa. It does not include information for county roads or city streets.

• Hands-free, eyes-free audio notifications of traffic events while you drive.
• A zoom-enabled map with selectable traffic event icons.
• Near real-time updates on winter road conditions, traffic incidents, construction, and road closures.
• Current traffic speeds and traffic camera images statewide.
• Citizen reports via Waze.
• Electronic roadway sign messages.
• Highway rest area locations.

The primary responsibility of every driver is the safe operation of their vehicle. While traveling, mobile communication devices should be used only when the motor vehicle is at a complete stop off the traveled portion of the roadway. Do not text and drive (it's against the law) or use this app while driving.

We welcome your feedback on this app. Please send your suggestions, questions or concerns in an email to
