ISO 3691-4 is an international standard officially titled "Industrial trucks — Safety requirements and verification — Part 4: Driverless industrial trucks and their systems." This document, published by the International Organization for Standardization (ISO), is the definitive global benchmark for the safety of driverless industrial vehicles.
ISO 3691‑4 requires that the AGV or AMR be equipped with collision avoidance systems that can detect obstacles—especially persons—and initiate braking or evasive actions before a collision occurs. In many implementations, this is achieved through (also known as “active detection fields”): the truck automatically switches between larger (warning) fields at higher speeds and smaller (protective) fields at lower speeds, ensuring that stopping distances remain within the detection range.
: Adjust scanner ranges based on floor friction and maximum payloads. Iso 3691-4 Pdf
Maintain a comprehensive file including the risk assessment, system layout, test results, and training records. Conclusion
If your vehicle is manually driven (even occasionally), ISO 3691-1 applies. If it is driverless, ISO 3691-4 is mandatory. ISO 3691-4 is an international standard officially titled
The is more than a technical document—it is a critical safety tool for any organization deploying driverless industrial trucks. By adhering to this standard, you reduce workplace accidents, ensure regulatory compliance, and build a foundation for scalable, trustworthy automation.
Having the PDF on a hard drive is not compliance. Here is a practical roadmap for facility managers. : Adjust scanner ranges based on floor friction
