Highway Advisory Radio
Highway Advisory Radio (HAR), which operates on 1610 AM, is used to broadcast public safety and travel advisory information to the motoring public. The primary function of HAR is to deliver timely highway and traffic condition information to people utilizing the system to reduce congestion and enhance customer safety. When prompted by either flashing yellow lights on area roadside signs or when indicated on Dynamic Message Signs, tune your radio to 1610 AM for the latest emergency or construction information.
