A) We are not an official source of traffic or real-time data. We have contracts and licenses to display certain up-to-date information that comes direct from some DOTs in various states, and the traffic flow on the maps is provided by Google or MapQuest. However, the data shown here should only be used for light informational and reference purposes and not to make critical decisions. Your safest option on the web is to use your state-run traffic website, or to call the DOT traffic line for your state, local authorities, or the state's 511 number if available.
