              5.5. Warning signal

              5.5.1. The warning signal referred to in paragraph 5.3.1.2. above shall be a signal differing, e.g. in mode or activation strategy, from the information signal specified in paragraph 5.4.

              5.5.2. It shall be easily understandable for the driver to relate the warning signal to the potential collision. In case the warning signal is an optical signal this signal shall also be visible by daylight and at night.

              5.5.3. The warning signal shall be activated at the earliest when the system detects a potential collision, e.g. by the intention of a turn towards the bicycle, e.g. by evaluating the distance between or trajectory intersection of vehicle and bicycle, direction indicator activation or similar. The strategy shall be explained in the information referred to in paragraph 6.1. It shall not depend solely on the activation of the direction indicator.

                The Technical Service shall verify the operation of the system according to the strategy.

              5.5.4. The warning signal referred to in paragraph 5.3.1. is not required for vehicles of categories N2 with a technically permissible maximum mass not exceeding 8 tonnes and M2.

              5.6. Failure warning signals

              5.6.1. The failure warning referred to in paragraph 5.3.1.7. above shall be a yellow optical warning signal, and shall be other than or clearly distinguishable from the information signal. The failure warning signal shall be visible by daylight and night, and shall be easily verifiable by the driver from the driver's seat.

              5.6.2. The optical warning signal referred to in paragraph 5.3.1.6. shall indicate that the BSIS is temporarily not available. It shall remain active as long as the BSIS is not available. The failure warning signal specified in paragraph 5.3.1.7. above may be used for this purpose.

              5.6.3. The BSIS optical failure warning signals shall be activated with the activation of the vehicle master control switch. This requirement does not apply to warning signals shown in a common space.

              5.7. Provisions for inspection

              5.7.1. It shall be possible to confirm the correct operational status of the BSIS by a visible observation of the failure warning signal status.

6.  Test procedure
              6.1.  The manufacturer shall provide a documentation package which gives access to the basic design of the system and, if applicable, the means by which it is linked to other vehicle systems. The function of the system including its sensing and warning strategy shall be explained and the documentation shall describe how the operational status of the system is checked, whether there is an influence on other vehicle systems, and the method(s) used in establishing the situations which will result in a failure warning signal being displayed. The documentation package shall give sufficient information for the Type Approval Authority
