Highway Advisory Radio

Products / Highway Advisory Radio

The Hoosier Company is a distributor for MH Corbin who manufactures highway information systems. Their Highway Advisory Radio (HAR) system utilizes AM or FM radio frequencies to broadcast messages to motorists. Informing drivers before they encounter delays and add to traffic problems is important for maintaining a safe driving environment. Since AM radio is a standard feature in nearly all vehicles, using M.H. Corbin HAR is one of the most practical ways to get the message out to everyone.


The M.H. Corbin Highway Advisory Radio (HAR) systems, can also be referred to as the Travelers’ Information Stations (TIS), are low powered AM radio stations licensed to governmental agencies to broadcast messages to travelers or residents through the use of their AM Radio. Some examples are as follows:

  • Emergency Evacuation Information
  • Amber Alert
  • Terrorism Security and Threat Alerts
  • Gate Closures / Security Checkpoints
  • Incident Management
  • Work Zones
  • Traffic Advisory / Alternate Routes
  • Weather Information and Alerts


  • Battery backup for operation during extended power outages
  • GPS synchronized systems that broadcast a single message simultaneously throughout an area
  • Solar Max™ is the only mobile solar-powered HAR on the market
  • Class D HAR transmitter is the most efficient available

Hiway Max

The Hiway Max product is a stationary HAR System that utilizes AM or FM radio frequencies to broadcast messages to motorists within a four to six-mile radius. The system is typically used to notify motorists of traffic conditions, local points of interest, or emergency and evacuation information. Messages can be changed remotely by touch-tone telephone or computer.

Solar Max

The Solar Max mobile highway advisory radio system can broadcast messages to motorists typically three to five miles away -- enough time to improve merging traffic or to offer alternate routes. (The range of your station may be greater or less depending on several factors.) Should conditions vary, messages can be changed remotely with a quick call from any cellular or touch-tone telephone.
