The disadvantages and advantages are outlined of various devices for warning oncoming traffic of the presence of a disabled vehicle. In addition to the four-way hazard flashers (rear stop lights and front parking lights) required in all new cars, vans, and pickup trucks since the 1967 model year, warning devices available to the motorist include road flares, reflectors or reflective stanchions (e.g. red plastic triangles, circular red reflectors mounted on a stand), warning lights that plug into the car's cigarette lighter, and battery-operated flashlamps. A specific device is described in detail: Safe-T-Signal's Hazard Alert, a battery-powered rotating light with amber lens, turned by a small electric motor and mounted on a plastic stand (33 1/2 in. high overall). Although such a system is felt to be a good approach to the road hazard problem, it is advised that the average motorist would be better served by one of the previously mentioned warning devices. Without regular inspection and replacement of batteries, such devices as the Hazard Alert may not function when needed in an emergency.
