What Is UN ECE R158 (RVCS)?

UN ECE R158 is a United Nations regulation that establishes technical requirements for rear visibility systems and detection devices used on commercial vehicles. Its primary objective is to improve driver visibility behind the vehicle during reversing manoeuvres, helping reduce collisions with pedestrians, cyclists, vehicles, and other obstacles. The regulation recognizes technologies such as Rear-View Camera Systems (RVCS) and rear detection systems as effective solutions for improving rear visibility.

What Does UN ECE R158 Require for Trucks?

To support UN ECE R158, trucks must be equipped with approved rear visibility or detection solutions that enable drivers to better observe the area directly behind the vehicle. Depending on the vehicle configuration and compliance approach, fleet operators typically consider the following capabilities:
● Clear visibility of the rear blind area
● Reliable image quality in various operating conditions
● Stable performance during reversing
● Compliance with applicable certification requirements
● Integration with commercial vehicle platforms
These requirements make certified rear-view camera systems an important part of truck safety upgrades. As a commercial vehicle vision solution provider, STONKAM provides a complete portfolio of UN ECE R158-compliant rear visibility solutions designed for OEMs, fleet operators, and commercial vehicle integrators.

Why Is UN ECE R158 Becoming a Priority for Truck Fleets?

Commercial trucks naturally have larger rear blind zones than passenger vehicles. As fleets operate longer vehicles and more complex transport routes, improving rear visibility has become essential for both operational safety and regulatory compliance.
● Large vehicle structures create rear blind zones that drivers cannot directly observe.
● Traditional mirrors provide limited rear coverage, especially on long-body trucks and tractor-trailers.
● People, vehicles and obstacles behind the truck may remain unnoticed during daily operations.
● Rear visibility incidents increase repair costs, vehicle downtime and insurance claims.

What Do Truck Fleets Need to Support UN ECE R158 Requirements?

Rather than simply installing a rear camera, fleet operators should select a rear visibility solution that supports both UN ECE R158 compliance and long-term fleet operations. A complete solution should not only meet regulatory requirements but also provide reliable performance, easy integration, and scalability for different truck platforms.
Key considerations include:
● Clear HD rear imaging for reliable rear visibility
● Stable performance in commercial truck environments
● AI-powered safety assistance
● Compatibility with different truck platforms
● Scalable deployment for fleet-wide safety upgrades
