Make the scene safer
If possible, move out of active lanes to a safe stopping place. Use warning devices and hazard lights as required, and keep people away from traffic. If there is immediate danger, call emergency services.
Pinpoint your position
Record the highway, direction, nearest exit, mile marker, cross street, or exact address. Share access constraints, a trailer number, and whether the truck is in a yard or shoulder.
Describe what changed
State what the truck was doing when it stopped, warning messages, sounds, leaks, and whether it can move safely. A clear symptom helps determine whether a shop conversation or mobile-service inquiry makes sense.
Confirm availability before relying on it
Mobile and roadside service are subject to current capability, location, and issue. Call a preferred location directly to discuss what may be possible; do not assume a response time or coverage area.
Next step
For a specific truck, share its location, make and model, warning messages, and observed symptoms with a repair location. Availability and repair scope need direct confirmation.
