Components - Highway Advisory Radio (HAR)
HAR is a system of low-power radio transmitters licensed for state use. Signs along highways throughout Wisconsin direct travelers to dial either AM 1610, AM 1620 or AM 530.
The Wisconsin Department of Transportation often uses HAR to provide short, pre-recorded messages in areas with ongoing highway construction projects. HAR is also used for special events such as Summerfest and State Fair.
