The working group has been set up to define a standard for collecting and distributing road accident and incident event data and to define a common standard for measuring driver behaviour.

Stakeholders include advisory groups such as PACTS, as well as CLOCs and CILT, academic institutions such as Loughborough University and TRL and organisations including RAC, Allianz, HDI Global, City of London Council, FTA, Aqaurius, and Osborne Clarke.

All CMS vehicle hardware supports the IRIS data standards.
