Guide To: ECE R165 - Reverse Warning

UN ECE R165, or Regulation No. 165 of the Economic Commission for Europe of the United Nations, is a regulation that specifies the requirements for audible reverse warning devices for power-driven vehicles. These devices are used to warn pedestrians and cyclists of the presence of a reversing vehicle.

UN ECE R165 applies to all new passenger cars, vans, trucks, buses, and trailers that are manufactured after 1 July 2022. The regulation specifies the requirements for the audible reverse warning device, including the type of sound that must be emitted, the volume of the sound, and the duration of the sound. It also specifies the test methods that must be used to verify that vehicles meet the requirements of the regulation.

Here are some of the key requirements of UN ECE R165:

The audible reverse warning device must emit a sound that is audible to pedestrians and cyclists at a distance of at least 20 meters. The audible reverse warning device must emit a sound that is distinct from other sounds that are emitted by the vehicle. The audible reverse warning device must emit a sound that is continuous for at least 2 seconds when the vehicle is reversing. UN ECE R165 is an important regulation that helps to improve the safety of pedestrians and cyclists on the road. By requiring vehicles to meet certain standards, the regulation helps to ensure that these vehicles are equipped with a system that can warn pedestrians and cyclists of the presence of a reversing vehicle.

Here are some additional points about UN ECE R165:

Vehicles that meet the requirements of UN ECE R165 are marked with the UN ECE R165 approval number. Vehicles that do not meet the requirements of UN ECE R165 may not be sold or registered in some countries. The requirements of UN ECE R165 are being continuously updated to reflect the latest research on pedestrian and cyclist safety. I hope this helps! Let me know if you have other questions.
