ISO and Road Vehicles


ISO AND ROAD VEHICLES iso and road vehicles statistics

DID YOU KNOW? Anyone who has driven a road vehicle of almost any make, almost anywhere in the world, will have directly benefitted from ISO 2575, which specifies the familiar symbols for controls and indicators we are accustomed to seeing on the dashboard. 

Who benefits from ISO standards for road vehicles? 

We’ve discussed ISO and energy, construction, the supply chain and we’ve debunked some myths – But what about ISO and road vehicles? Read on to learn why ISO and your vehicle are so important. 


ISO standards make driving a vehicle simpler and safer, while protecting passengers (especially children) and pedestrians, and lower the cost of buying vehicles.


ISO standards gives technical basis for regularly reviewed & improved legislation on things like safety and pollution.


ISO Standards give specifications for safety, quality, performance and environmental impact. They set out harmonized requirements that enable outsourcing, fair competition, the participation of suppliers from developing countries and drive down costs as they facilitate competitive tendering.

What do ISO Standards for road vehicles cover?

Much of the work in these areas is the focus of the ISO technical committee, called ISO/TC 22, Road Vehicles, which has developed more than 820 standards & updates worldwide. The committee’s made of 75 different participating and observing national standards bodies, as well as automotive-sector associations and international bodies such as the World Health Organization.

These standards aim to:

  • Improve compatibility, interchangeability and safety
  • Specify the requirements for harmonized test procedures to evaluate performance.

Why do we need ISO standards for road vehicles?

Electric Vehicles 

ISO/TC 22 Road vehicles has also developed a range of standards specifically for electric, hybrid and fuel-cell road vehicles. A number of these provide requirements for functional safety, test methods, on-board energy storage systems and measuring fuel consumption.

ISO 17409 Electrically Propelled road vehicles connection to an external electric power supply—Safety requirements

ISO 234741, Hybrid-electric road vehicles exhaust emissions and fuel consumption measurements—Part 1: Non-externally charged vehicles.

Intelligent Transport Systems 

Increasingly, road vehicles are being equipped with systems and networks based on information and communication technologies intended to improve safety, traffic control, navigation, fee collection and identification. Today’s communication capabilities give vehicles the potential to anticipate and avoid collisions, transmit their position to emergency services in case of an accident, navigate the quickest route to their destination, take advantage of up-to-the-minute traffic reports, identify the nearest available parking space, minimize their carbon emissions and provide multimedia communications.

ISO/TC 204,Intelligent transport systems focuses mainly on this area and has developed more than 220 standards*.

*These include the ISO 15638 series on telematics applications for regulated commercial freight vehicles (TARV) and ISO 11067, which gives performance requirements and test procedures for curve speed warning systems (CSWS).

Tyres and Other Components 

ISO/TX 3, Tyres, rims and valves has developed 78 standards, including the ISO 4000 series on passenger car tyres and rims and the ISO 4249 series on motorcycle tyres and rims.

Road Safety

ISO 39001, Road traffic safety (RTS) management systems—Requirements with guidance for use, developed by ISO/TC 241, road traffic safety managementis widely regarded as a major contribution to the United Nations’ Decade of Action for Road Safety 2011-2020.

Future ISO 39002, Good practices for implementing commuting safety management, aims to reduce the amount of fatalities and severity of injuries caused by road accidents, by providing solutions and recommending measures that organizations can use to protect their staff.

Road-safety-related standards are also developed by other ISO technical committees, for example to make crossing the street safer for disabled persons.

Vehicle Safety

With the latest technological progress bringing us everything from advanced navigation systems to driverless cars, putting measures in place to spot potential risks across the whole vehicle lifespan is more important than ever.

ISO 26262 (series), Road vehicles—Functional safety, outlines an automotive-specific risk-based approach to help avoid any potential system failures.

Looking Forward

Cyber Security 

A quick look at your dashboard will give you an idea of how connected vehicles are – and it is only increasing. From your GPS to other gauges and sensors telling you when your tyre pressure is low, there is constant interaction between in-vehicle embedded systems that communicate wirelessly. As this interconnectivity grows, so does the risk of cyber-attacks, threatening not only our safety but our personal information. Work has recently started on standards to address these issues by providing recommendations and solutions for building cyber security into vehicles

Hydrogen Vehicle Stations

If fuel-cell, electric and alternative-fuel vehicles are the future, there need to be adequate stations for refuelling them.

A new technical specification, ISO/TX 19880-1, Gaseous hydrogen—Fuelling stations—Part:1 General requirements, will contribute to the proliferation of hydrogen fuelling stations by providing important guidelines on their safety and performance. It covers everything from hydrogen production and delivery, to compression, storage and fuelling of a hydrogen vehicle, and provides a useful stepping stone to an International Standard in this area, due to be published in 2017.
