Compliance Labeling Of Warning Devices 49 Cfr Section 571.125

The agency issued FMVSS No. 125, "Warning Devices", which applies to devices, without self- contained energy sources, which are designed to be carried mandatorily in buses and trucks that have a gross vehicle weight rating (GVWR) greater than 10,000 pounds and voluntarily in other vehicles. These devices are used to warn approaching traffic of the presence of a stopped vehicle, except for devices designed to be permanently affixed to the vehicle. Each manufacturer of warning triangles must label each device to comply with Standard No. 125. This standard establishes requirements for devices, without self-contained energy sources. Without proper deployment and use, the effectiveness of the devices may be greatly diminished, and may lead to serious injuries due to rear end collisions between moving traffic and disabled vehicles. The warning device shall be permanently and legibly marked and also provide instructions for its erection and display. Each device shall be labeled with; (a) the name of the manufacturer, (b) the month and year of manufacture, (c) the DOT symbol, or the statement that the warning device complies with all applicable FMVSS. The instructions for each device shall include a recommendation that the driver activate the vehicular hazard warning signal lamps before leaving the vehicle to erect the warning device. Also, the instructions shall include an illustration indicating recommended positioning. Without these devices and instructions, there could be more deaths and injuries caused by stopped or disabled motor vehicles.
