The Working Party on General Safety (GRSG) is the main decision-making body under WP.29 for matters concerning vehicle safety related to the general construction of vehicles with particular attention to safety requirements for buses and motor coaches. GRSG reviews all significant proposals in this area and decides whether to forward them to the World Forum for final decisions on their adoption. GRSG also oversees subgroups of experts established to address general safety issues.
GRSG regularly gathers more than 65 specialists in vehicle construction and safety from government agencies and non-governmental organizations across the world.
GRSG usually convenes during late April/early May and October of each year.

| UN R125: Proposal for a Supplement to the original text, 01, 02, and 03 series of amendments |
| Reference Number: GRSG/2026/23 |
|
Proposal to resolve a longstanding inconsistency in UN R125 between the lower datum point (§5.1.1.3, set at 5°) and the obstruction requirement (§5.1.3, set at 4°), by aligning the lower datum point to 4° while retaining upper and lateral aspects of §5.1.1. unchanged. The 5° datum point has never been used for any technical requirements beyond serving as a reference point, while the 4° obstruction requirement has prior precedent. As this is a vehicle rather than component requirement, the datum point is also proposed for deletion from UN R43, retaining it solely in UN R125. |
