A warning device deployment system for an autonomous vehicle. The warning device deployment system includes one or more warning device deployment mechanisms attached to the autonomous vehicle. The warning device deployment system includes one or more warning devices stored in the one or more warning device deployment mechanisms. The one or more warning devices are deployed from the one or more warning device deployment mechanisms when the autonomous vehicle is in an emergency.

A warning device for a warning device deployment system for an autonomous vehicle. The warning device includes a tetrahedron frame having four triangular faces and at least one reflective material on the tetrahedron frame. The tetrahedron frame defines an expanded shape of the warning device. The warning device is self-expandable such that the warning device is compactable to a reduced volume when the warning device is stored in the warning device deployment system and expandable to the expanded shape when the warning device is deployed from the warning device deployment system. A warning device deployment system includes one or more warning device deployment mechanisms attached to the autonomous vehicle and the one or more warning devices stored in the one or more warning device deployment mechanisms. The one or more warning devices are deployed from the one or more warning device deployment mechanisms.

A hitch mounted light assembly includes a mount configured to releasably communicate with a hitch of the vehicle. The assembly is configured with a set of traffic lights intended for the use on the rear of the vehicle. The traffic lights pivot outward and upward from a vertical bar in communication with the mount. The elevation of the lights is adjustable. The assembly is configured to transition between a storage configuration and an expanded configuration intended for use. The traffic lights are operable through a conventional trailer plug on the vehicle.

A deployable safety zone system includes a truck including a tank and a fuel nozzle assembly and an alarming system including a sensor assembly mounted to the truck. The alarming system defines an alarmed safety zone disposed adjacent the truck and adjacent the fuel nozzle assembly. The sensor assembly defines a perimeter of the alarmed safety zone. The perimeter is free of any physical support structures. A method for creating a deployable alarming and safety zone includes operably engaging an alarming system including a sensor assembly with a truck and deploying an alarmed safety zone including a perimeter adjacent the truck. The perimeter is defined by the sensor assembly and the perimeter is free of any physical support structures.
