4.7.
The warning system may be temporarily interrupted by other warning signals providing important safetyrelated messages.
4.8.
A facility to permit the driver to dim the visual alarms provided by the warning system may be provided on vehicles for use by the rescue services or on vehicles designed and constructed for use by the armed services, civil defence, fire services and forces responsible for maintaining public order.
4.9.
Details of the driver warning system activation and deactivation procedures are specified in Appendix 2 to this annex.
4.10.
As part of the application for type approval under this Regulation, the manufacturer shall demonstrate the operation of the driver warning system, as specified in Appendix 1 to this annex.

Driver inducement system
5.1.
The vehicle shall incorporate a two-stage driver inducement system starting with a low-level inducement (a performance restriction) followed by a severe inducement (effective disablement of vehicle operation).
5.2.
The requirement for a driver inducement system shall not apply to engines or vehicles for use by the rescue services or to engines or on vehicles designed and constructed for use by the armed services, civil defence, fire services and forces responsible for maintaining public order.
Permanent deactivation of the driver inducement system shall only be done by the engine or vehicle manufacturer.
5.3.
Low-level inducement system The low-level inducement system shall reduce the maximum available engine torque across the engine speed range by 25 per cent between the peak torque speed and the governor breakpoint as described in Appendix 3 to this annex.
The maximum available engine torque below the peak torque speed of the engine before imposition of the torque reduction shall not exceed the reduced torque at that speed.
The low-level inducement system shall be activated when the vehicle becomes stationary (2) for the first time after the conditions specified in paragraphs 6.3., 7.3., 8.5. and 9.4. below, have occurred.
5.4.
Severe inducement system The vehicle or engine manufacturer shall incorporate at least one of the severe inducement systems described in paragraphs 5.4.1. to 5.4.3. and the "disable on time limit" system described in paragraph 5.4.4.
5.4.1.
A "disable after restart" system shall limit the vehicle speed to 20 km/h ("creep mode") after the engine has been shut down at the request of the driver ("key-off").
5.4.2.
A "disable after fuelling" system shall limit the vehicle speed to 20 km/h ("creep mode") after the fuel tank level has risen a measurable amount, which shall not be more than 10 per cent of the fuel tank capacity and shall be approved by the Type Approval Authority based on the technical capabilities of the fuel level meter and a declaration by the manufacturer.
5.4.3.
A "disable after parking" system shall limit the vehicle speed to 20 km/h ("creep mode") after the vehicle has been stationary for more than one hour.
(2) A vehicle shall be considered as stationary at the latest 1 minute after the vehicle speed has been reduced to zero km/h.
The engagement of any device such as a park-brake, a trailer-brake, or a hand-brake shall not be necessary for being stationary.
