Industrial trucks - Safety requirements and verification - Part 4: Driverless industrial trucks and their systems (ISO 3691-4:2023)
This document specifies safety requirements and the means for their verification for driverless industrial trucks (hereafter referred to as trucks) and their systems.
Examples of driverless industrial trucks (trucks as defined in ISO 5053-1:2020) include: “automated guided vehicle”, “autonomous mobile robot”, “bots”, “automated guided cart”, “tunnel tugger”, “under cart”, etc.
This document is also applicable to driverless industrial trucks which are provided with:
- automatic modes which either require operators’ action(s) to initiate or enable such automatic operations;
- the capability to transport one or more riders (which are neither considered as drivers nor as operators);
- additional manual modes which allow operators to operate the truck manually; or
- a maintenance mode which allows manual operation of truck functions for maintenance reasons.
This document is not applicable to trucks solely guided by mechanical means (rails, guides, etc.) or to remotely-controlled trucks, which are not considered to be driverless trucks.
For the purposes of this document, a driverless industrial truck is a powered truck, which is designed to operate automatically. A driverless truck system comprises the control system, which can be part of the truck and/or separate from it, guidance means and power system. Requirements for power sources are not covered in this document.
The condition of the operating zone has a significant effect on the safe operation of the driverless industrial truck. The preparations of the operating zone to eliminate the associated hazards are specified in Annex A.
This document is applicable to all significant hazards, hazardous situations or hazardous events during all phases of the life of the truck (ISO 12100:2010, 5.4), as listed in Annex B, relevant to the applicable machines when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
In particular, this document does not apply to significant hazards related to:
- noise;
- vibrations;
- ionising and non-ionising radiation;
- laser radiation;
- sales literature (commercial documents);
- declaration of vibrations transmitted by mobile machinery.
It does not apply to additional hazards that can occur:
- during operation in severe conditions (e.g. extreme climates, freezer applications, strong magnetic fields);
- during operation in nuclear environments;
- from trucks intended to operate in public zones (see in particular ISO 13482:2014);
- during operation on a public road;
- during operation in potentially explosive environments;
- during operation in military applications;
- during operation with specific hygienic requirements;
- during operation in ionizing radiation environments;
- during the transportation of (a) person(s) other than (the) intended rider(s);
- when handling loads the nature of which can lead to dangerous situations (e.g. molten metals, acids/ bases, radiating materials);
- for rider positions with elevation function higher than 1 200 mm from the floor/ground to the platform floor.
This document does not contain safety requirements for trailer(s) being towed behind a truck.
This document does not contain safety requirements for elevated operator trucks.
This document does not apply to trucks manufactured before the date of its publication.

Frequently Asked Questions about ÖNORM EN ISO 3691-4
When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
If you have an extensive portfolio of standards, we recommend using a professional standards management tool. With effects 2.0, you can manage your standards centrally and efficiently. You can optimise your procurement processes and benefit from an integrated information and subscription service. This ensures you are always up to date and never miss any relevant developments.
