511 Traffic Systems

In 2000, the Federal Communications Commission (FCC) began a plan to assist motorists across the United States by designating 511 as the single traffic information telephone number for the entire country. Previously, some states had three to five different travel information numbers. Consolidating these services into one easy-to-use number offers motorists a valuable tool for making informed decisions while on the road. The 511 service is also known as America's Traveler Information Telephone Number.

Unfortunately, the 511 service is still under development in Missouri and thus only available to travelers in the greater St. Louis metropolitan area―St. Louis City and County, as well as Franklin, Jefferson, and St. Charles counties. There is no official timeline to bring 511 service statewide.

If you are traveling in one of the 28 states with a fully active 511 system, however, you can quickly obtain travel information by simply dialing 511 from your phone. In addition, each state with an active 511 system has a special number you can use to access information when you're outside the area.

On the Web

The Missouri Department of Transportation (MoDOT) maintains a real-time Web site with current information about road conditions, weather forecasts, construction workzones and major traffic incidents.

Responsible Cell Phone Usage

Although the 511 service can be a tremendous asset for frequent travelers, it's important to be cautious when calling from your cell phone. If possible, you'll want to pull over to a safe location before making the call. Distracted driving, especially in heavy traffic or under poor weather conditions, can be a serious safety hazard.
