Your request is in. A local unit will call you back at the number you gave us.
Stay visible and stay safe: hazards on, triangles out if you can place them without stepping into traffic, and stay in the cab if the shoulder is tight. Have your location ready — highway, direction, and the nearest exit or mile marker — plus which tire or system failed, and whether you are loaded or empty. That is everything dispatch needs to roll the right truck the first time.
