Iowa 511 app for Android and iPhone

The Iowa DOT has a 511 smartphone application to meet the growing trend of information on mobile devices - "Iowa 511." The application works on smartphones and tablets that operate on the iOS and Android platforms.

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.

Features include:

  • Hands-free, eyes-free audio announcements of upcoming traffic events as you travel along your route
  • A zoom-enabled map with tappable traffic event icons and surrounding camera views
  • Near real-time updates on winter road conditions (including surrounding states), traffic incidents, construction, truck restrictions, and road closures
  • Trucker Mode with resources specific to commercial vehicle operators
  • Create and manage Your 511 personalized account including saved routes, areas, favorite camera views, and alerts via email and/or text.
  • Travel time delays associated with traffic reports (look for the orange glowing icons)
  • Current traffic speeds
  • Traffic camera images and streaming video throughout the state. Sign up for an account to save your favorite cameras for easy access later.
  • Snow plow camera images and locations
  • Towing prohibited (tow ban) events for winter storms
  • Real-time weather radar
  • Weather stations with alerting for inclement weather
  • Rest area locations statewide including real-time truck parking availability at rest areas and select private truck stops along I-80, and portions of I-29, I-35, I-235, and I-380.
  • Weigh Station Locations
  • Citizen reports via Waze
  • Electronic Message Signs


Remember, the primary responsibility of every driver is the safe operation of their vehicle. Iowa law prohibits individuals from using a handheld electronic communication device to write, send or read a text message while driving a motor vehicle.
