ECE Regulation No. 93 is part of a broader framework of safety standards developed by the United Nations Economic Commission for Europe (UNECE) to promote vehicle safety among member countries. By complying with this regulation, manufacturers help reduce the risk of underrun collisions and improve the survivability of road users in crashes involving large commercial vehicles, thereby contributing to safer road travel for all.



​

The test procedures are clearly defined in this regulation to ensure compliance. These include both static and dynamic tests that simulate real-world conditions. Manufacturers are required to perform these tests to demonstrate that their vehicles meet the required standards. The regulation also includes provisions for the maintenance and inspection of these components to ensure ongoing compliance throughout the vehicle’s lifespan.

This regulation outlines various technical requirements for the construction, installation, and performance of Front Underrun Protective Devices (FUPDs). These requirements ensure that FUPDs are sufficiently strong to withstand specified impact forces and maintain functionality under different environmental conditions. The objective is to prevent smaller vehicles from sliding underneath larger ones during frontal collisions, thereby reducing the risk of severe injuries or fatalities.

​ECE Regulation No. 93 sets uniform provisions for the approval of vehicles with regard to Front Underrun Protective Devices (FUPDs). This regulation is crucial to ensure that FUPDs are designed and installed in a way that provides effective protection for occupants of smaller vehicles in the event of a collision with a larger vehicle, thereby improving overall road safety.
