The Commission should assess the feasibility of extending the mandatory installation of tyre pressure monitoring systems, lane departure warning systems and advanced emergency braking systems to other categories of vehicle and, if appropriate, propose an amendment to this Regulation.

2. Subject to exemptions established in accordance with Article 14(3)(a), vehicles of categories M, M, N and N shall be equipped with a lane departure warning system which shall meet the requirements of this Regulation and its implementing measures.

In particular, the Commission should be empowered to establish the specific procedures, tests and requirements for the type-approval of motor vehicles, components and separate technical units; to define more precisely the characteristics a tyre must fulfil to be defined as ‘special use tyre’, ‘off-road professional tyre’, ‘reinforced tyre’, ‘extra load tyre’, ‘snow tyre’, ‘T-type temporary-use spare tyre’ or ‘traction tyre’; to set out specific safety requirements for vehicles intended for the transport of dangerous goods by road within or between Member States; to exempt certain vehicles or classes of vehicles of categories M, M, N and N from the obligat ...[+++]ion to install advanced emergency braking systems and/or lane departure warning systems; to amend the limit values on rolling resistance and rolling noise for tyres as a result of changes in test procedures without lowering the level of protection of the environment; to establish rules on the procedure for the determination of noise levels of tyres; to shorten the sell-off period for tyres not complying with the requirements set out in this Regulation and its implementing measures; and to amend Annex IV to include the Regulations of the United Nations Economic Commission for Europe (UNECE Regulations) which are mandatory under Council Decision 97/836/EC of 27 November 1997 with a view to accession by the European Community to the Agreement of the United Nations Economic Commission for Europe concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted to and/or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions .

During a prescribed transient cycle of warmed-up engine operating conditions, which is based closely on road-type-specific driving patterns of heavy-duty engines installed in trucks and buses, the above pollutants shall be examined either after diluting the total exhaust gas with conditioned ambient air (CVS system with double dilution for particulates) or by determining the gaseous components in the raw exhaust gas and the particulates with a partial flow dilution system.

A sample of the diluted exhaust gas is taken from the dilution tunnel DT of a partial flow or full flow dilution system through the particulate sampling probe PSP and the particulate transfer tube PTT by means of the sampling pump P. The sample is passed through the filter holder(s) FH that contain the particulate sampling filters.

At the start of the engine or test sequence, if the cycle is started directly from the preconditioning, the particulate sampling system shall be switched from by-pass to collecting particulates.
