FCC-Permitted Broadcast Content
Below is a formula to help information radio station operators determine what content is appropriate to broadcast on their ALERT AM, Information Station, RadioSTAT or VoiceStar stations. The FCC has designated all these stations to be forms of Travelers' Information Stations. (For more detail regarding TIS parameters, please see the "TIS Background" section at the bottom of this page.)
What am I allowed to broadcast?
When planning broadcasts, it helps to remember the acronym TIDE; because, according to the FCC, broadcast content is permitted to relate to Travel, Imminent Danger or Emergencies. Following are examples of each with FCC references. The FCC qualifies all examples below by stating that local public safety officials are charged with determining what content on their stations describes situations of imminent danger.
Travel
Operator Discretion
The Federal Communications Commission affords public safety officials “…discretion regarding the …service. Given their intimate knowledge of local conditions and considering the limited area of operation of TIS base stations, TIS licensees are in the best position to determine what constitutes an “imminent [threat to] safety-of-life or property, as well as when emergency conditions reach the level of a hurricane, flood, earthquake or similar disaster” (****)

What exactly is a TIS station?     
We often refer to the Travelers' Information Stations in general terms as “information radio stations.” For specifically outfitted stations used in emergency applications, we use the phrase “emergency advisory radio.” For traffic applications and station setups, we apply the term “highway advisory radio." All these information radio stations are formally considered to be Travelers' Information Stations by the FCC.

To qualify as a TIS under the FCC Part 90.242 Rules umbrella, stations must operate at no more than 10 watts on the AM-band frequencies 530-1700 kHz. Signal coverage is limited to 2.0 mV/m at 1.5 km, which typically yields a signal radius of 3-5 miles. Motorists are notified to tune to the stations via road signs, which may incorporate flashing beacons. See also the FCC TIS Compliance Guide, published in 2014.

Federal agencies and state/local governments may license the stations through the NTIA and FCC, respectively. (NTIA is an acronym for National Telecommunications & Information Administration.) Some of those entities acquire funding for station purchases through grants and/or partnerships with constituencies.
