GTR 8: Request for authorization to develop an amendment
World Forum Informal Electronic Stability Control Systems ESC Systems Electronic stability control systems Electronic Stability Control Systems ESC Systems Uniform provisions concerning the approval of passenger cars with regard to electronic stability control systems The objective of this proposal is to develop, in the framework of the 1998 Agreement, an amendment to UN Global Technical Regulation (GTR) No. 8 on Electronic Stability Control to amend to the testing provisions to accommodate the latest innovations for steering systems which have significantly low steering gear ratio (i.e. quick steering characteristics).

UN R140: Proposal for Supplement 4
World Forum Working Electronic Stability Control Systems ESC Systems Uniform provisions concerning the approval of passenger cars with regard to electronic stability control systems Proposal to allow for the use of the maximum operable steering wheel angle of a steering system’s design in cases where the normalized angle as calculated under the regulation cannot meet the fixed values of the regulation (i.e., between 270 and 300 degrees). The intention is to enable approval of eventual systems (e.g., steer-by-wire) that may use low steering gear ratios.
