  • Required Action: State your exact highway name, direction, mile marker, vehicle unit number, and the specific mechanical failure.

  • Practice Dialogue:

    Dispatcher/Fleet Support: "Fleet Service, state your unit number and location."

    Driver: "This is Unit 305. I am broken down on I-80 West at Mile Marker 215, on the right shoulder. I lost air pressure in my brake line, and my hazard lights and warning triangles are deployed."

    Fleet Support: "Is your load secure, and are you in a safe position?"

    Driver: "Yes, the truck is fully on the shoulder, cargo is secure, and I am safe in the cab."

Scenario B: Communicating During Severe Weather or Road Closures

  • Situation: Heavy snow or severe wind forces state highway patrol to implement a commercial vehicle shutdown.
