Documents GRRF/2015/40 and 41 propose to align GTR 3 and UN R78 with the provisions for anti-lock braking systems used in other regulations. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle.
