49. The expert from the Netherlands introduced GRSG-125-05 on odometer in vehicles. He underlined that the odometer readings were relevant for many applications, such as roadworthiness, environmental performances of the vehicles and current and future domestic applications. Therefore, he proposed establishing a TF to discuss potential measures for accuracy and anti-tampering of odometer/mileage values. He also clarified that this work would entail only M1 and N1 vehicle categories. The expert from IMMA requested the exemption of the L category of vehicle from this work for the time being. GRSG agreed to establish a TF on this subject, and requested the expert from the Netherlands to draft ToR for the proposed TF and the secretariat to provide a webpage. At the same time, it was agreed to resume discussion on this subject at the October 2023 session of GRSG.
