Article 3

For the purposes of this Regulation, the definitions laid down in Article 3 of Regulation (EU) 2018/858 apply. In addition, the following definitions apply: (1) ‘vulnerable road user’ means non-motorised road users, including, in particular, cyclists and pedestrians, as well as users of powered two-wheelers; (2) ‘tyre pressure monitoring system’ means a system fitted on a vehicle which can evaluate the pressure of the tyres or the variation of pressure over time and transmit corresponding information to the user while the vehicle is running; (3) ‘intelligent speed assistance’ means a system to aid the driver in maintaining the appropriate speed for the road environment by providing dedicated and appropriate feedback; (4) ‘alcohol interlock installation facilitation’ means a standardised interface that facilitates the fitting of aftermarket alcohol interlock devices in motor vehicles; (5) ‘driver drowsiness and attention warning’ means a system that assesses the driver’s alertness through vehicle systems analysis and warns the driver if needed; (6) ‘advanced driver distraction warning’ means a system that helps the driver to continue to pay attention to the traffic situation and that warns the driver when he or she is distracted; (7) ‘emergency stop signal’ means a light-signalling function to indicate to other road users to the rear of the vehicle that a high retardation force is being applied to the vehicle relative to the prevailing road conditions; (8) ‘reversing detection’ means a system to make the driver aware of people and objects at the rear of the vehicle with the primary aim of avoiding collisions when reversing; (9) ‘lane departure warning system’ means a system to warn the driver that the vehicle is drifting out of its travel lane; (10) ‘advanced emergency braking system’ means a system which can automatically detect a potential collision and activate the vehicle braking system to decelerate the vehicle with the purpose of avoiding or mitigating a collision; (11) ‘emergency lane-keeping system’ means a system that assists the driver in keeping a safe position of the vehicle with respect to the lane or road boundary, at least when a lane departure occurs or is about to occur and a collision might be imminent; (12) ‘vehicle master control switch’ means the device by which the vehicle’s on-board electronics system is brought, from being switched off, as in the case where a vehicle is parked without the driver being present, to normal operation mode; (13) ‘event data recorder’ means a system with the only purpose of recording and storing critical crash-related parameters and information shortly before, during and immediately after a collision; (14) ‘frontal protection system’ means a separate structure or structures, such as a bull bar, or a supplementary bumper which, in addition to the original‐equipment bumper, is intended to protect the external surface of the vehicle from damage in the event of a collision with an object, with the exception of structures having a mass of less than 0,5 kg, intended to protect only the vehicle’s lights; (15) ‘bumper’ means any front, lower, outer structures of a vehicle, including attachments thereto, which are intended to give protection to a vehicle when involved in a low speed frontal collision with another vehicle; it does not include however any frontal protection system; (16) ‘hydrogen-powered vehicle’ means any motor vehicle that uses hydrogen as fuel to propel the vehicle; (17) ‘hydrogen system’ means an assembly of hydrogen components and connecting parts fitted on a hydrogen-powered vehicle, excluding the hydrogen-powered propulsion system or the auxiliary power unit; (18) ‘hydrogen-powered propulsion system’ means the energy converter used to propel the vehicle; (19) ‘hydrogen component’ means hydrogen containers and all other parts of hydrogen‐powered vehicles that are in direct contact with hydrogen or which form part of a hydrogen system; (20) ‘hydrogen container’ means the component within the hydrogen system that stores the primary volume of hydrogen fuel; (21) ‘automated vehicle’ means a motor vehicle designed and constructed to move autonomously for certain periods of time without continuous driver supervision but in respect of which driver intervention is still expected or required; (22) ‘fully automated vehicle’ means a motor vehicle that has been designed and constructed to move autonomously without any driver supervision; (23) ‘driver availability monitoring system’ means a system to assess whether the driver is in a position to take over the driving function from an automated vehicle in particular situations, where appropriate; (24) ‘vehicle platooning’ means the linking of two or more vehicles in a convoy using connectivity technology and automated driving support systems which allow the vehicles to maintain automatically a set, close distance between each other when connected for certain parts of a journey and to adapt to changes in the movement of the lead vehicle with little to no action from the drivers; (25) ‘maximum mass’ means the technically permissible maximum laden mass stated by the manufacturer; (26) ‘A-pillar’ means the foremost and outermost roof support extending from the chassis to the roof of the vehicle.
