Stay with your vehicle but remain alert to traffic around you. If you have reflective triangles or flares, place them behind your truck according to DOT guidelines. Gather your driver’s license, vehicle registration, and any relevant maintenance records that might help with diagnosis.

Our dispatcher will provide specific instructions based on your location and situation. We’ll also give you a direct phone number to reach your assigned technician once they’re en route to your location.
