Document GRRF-79-18
11 February 2015

Presently, it is not fully clear whether an anti-lock braking system (ABS) switch-off or altering mode is permitted on L-category vehicles, whereas it is clearly not allowed on other vehicle categories. This proposal is aimed at ensuring a consistent approach for all motor-vehicles equipped with anti-lock braking systems, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13.
