Guide To: ECE R69 - Rear marking plates for slow-moving vehicles

UN ECE R69, or Regulation No. 69 of the Economic Commission for Europe of the United Nations, is a regulation that specifies the requirements for rear marking plates for slow-moving vehicles (by construction) and their trailers. These devices are used to improve visibility of slow-moving vehicles, such as agricultural vehicles and construction machinery.

UN ECE R69 applies to rear marking plates that are either stand-alone or built into other light units, such as combination or multi-function lights. The regulation specifies the size, shape, color, and photometric performance of rear marking plates. It also specifies the test methods that must be used to verify that rear marking plates meet the requirements of the regulation.

UN ECE R69 is recognized by many countries around the world. This means that rear marking plates that have been approved under UN ECE R69 can be used on vehicles in these countries.

Here are some of the key requirements of UN ECE R69:

Rear marking plates must be red in color. Rear marking plates must have a minimum size of 250 mm x 150 mm. Rear marking plates must have a minimum photometric performance. Rear marking plates must be mounted at a height of at least 250 mm and not more than 1,500 mm above the road surface. Rear marking plates must be mounted at a distance of at least 400 mm from the side of the vehicle. UN ECE R69 is an important regulation that helps to improve the safety of vehicles on the road. By requiring rear marking plates to meet certain standards, the regulation helps to ensure that these devices are effective in improving visibility of slow-moving vehicles.

Here are some additional points about UN ECE R69:

Rear marking plates must be marked with the UN ECE R69 approval number. Rear marking plates must be installed in a way that ensures that they are visible to other road users. Rear marking plates must be replaced if they are damaged or become defective.
