ISO 39001: Road Traffic Safety Management Explained

ISO 39001 is the road traffic safety management system standard, and it applies to far more organisations than the ones that own lorries.

Its scope is any organisation that interacts with the road system. That includes employers whose staff drive to meetings, companies whose deliveries are subcontracted, and organisations whose sites generate traffic they do not control. If people are on the road because of what your organisation does, the standard is aimed at you.

What ISO 39001 requires

ISO 39001:2012 — Road traffic safety (RTS) management systems — Requirements with guidance for use — is a requirements standard, so it is certifiable. It runs to 37 pages and is maintained by ISO/TC 241.

Structurally it is a management system like any other: context, leadership, planning, support, operation, performance evaluation, improvement. What makes it distinctive is the model underneath.

The Safe System approach. The standard rests on the principle that people make mistakes and are physically vulnerable, so the road system should be designed to keep the consequences of those mistakes survivable. That is a different starting point from blaming driver error, and it drives everything the standard asks for.

The practical consequence is the performance factors an organisation must identify and manage, which fall into three groups:

• Exposure — how much road use your activity generates. Distance travelled, journeys made, vehicle and road types used.
• Intermediate safety outcomes — the factors that predict harm: speed, vehicle safety standards, restraint use, driver fitness and fatigue, route selection, junction design where you influence it.
• Final safety outcomes — deaths and serious injuries.

Final outcomes are the point but useless as a management signal for most organisations, because the numbers are small and lagging. The intermediate factors are what you actually manage, and being explicit about that distinction is one of the more useful things ISO 39001 does.

The reduction that makes it worth certifying

Most organisations that adopt ISO 39001 find their exposure is larger than assumed, because grey fleet — staff driving their own vehicles for work — never appeared in any register.

Those journeys generate the same duty of care as a company vehicle and usually none of the controls: no checks on insurance, roadworthiness, licence status, or hours driven before a long return trip. A structured exposure assessment is often the first time an organisation sees the whole picture.

Where ISO 39001 stands in 2026

Two facts from the ISO record are worth knowing before you plan.

A revision has been decided. ISO 39001:2012 sits at stage 90.92 — International Standard to be revised — and ISO/WD 39001.2 is under development at stage 20.20.

Stage 20.20 is a working draft. It has to pass committee draft, DIS and FDIS stages before publication, which is measured in years. This is not a reason to delay certification. The 2012 text is the certifiable standard today, and a management system built on the Safe System approach will carry forward.

There is a free amendment. ISO 39001:2012/Amd 1:2024 covers climate action changes and is listed at CHF 0.

Two related projects are also in development at ISO/TC 241: ISO/AWI 39002 on commuting safety management, and ISO/AWI 39005 on road infrastructure safety level classification. Commuting is the gap most organisations argue about, so 39002 is worth watching.

How ISO 39001 relates to standards you may hold

Where to start

1. Measure exposure honestly, including grey fleet and subcontracted transport. This is the number that changes the conversation.
2. Pick intermediate factors you can actually influence — speed, fatigue, restraint use, vehicle standards, route choice.
3. Set targets on those factors, not only on collisions, which are too rare to manage by.
4. Download Amendment 1; it costs nothing.
5. Integrate with ISO 45001 rather than running a parallel system.
6. Watch ISO/TC 241, but certify now — the revision is at working draft.
