  1. 2.1.1.1.

    The driver shall be able to actuate the spring brakes control from own driving seat, while keeping at least one hand on the steering control.

  2. 2.1.1.2.

    The braking performance prescribed in Annex II to this Regulation shall be fulfilled.

  3. 2.1.1.3.

    The prescribed performance shall be obtained without deviation of the vehicle from its course, without abnormal vibrations and without wheel-locking.
