Which type of advisory sign would inform drivers of an anticipated weather condition?

Highway advisory radio is specifically designed to provide drivers with real-time information regarding various road conditions, including anticipated weather conditions. These radio broadcasts can deliver crucial safety messages and alerts directly to motorists in a specific area, allowing them to make informed decisions about their travel routes or plans. The information can cover aspects such as severe weather warnings, road closures, or hazardous conditions, making it a vital tool in managing traffic safety.

Variable message signs also convey important information and can be used to display weather-related alerts; however, they offer limited text and may not provide as detailed or timely information as highway advisory radio. Transit stop displays are intended for public transportation users and generally do not provide weather-related traffic conditions. Roadside kiosks can offer a range of travel information, but they are less commonly used for immediate weather advisories compared to highway advisory radio.
