The Advanced Emergency Braking Systems (AEBS) and Lane Departure Warning Systems (LDWS) for commercial vehicles will be harmonised at international level following the agreement reached between the European Commission and its international partners.

At the meeting held by the United Nations' World Forum for Harmonization of Vehicle Regulations, the European Commission reached a deal with its international partners on new internationally harmonised rules on Advanced Emergency Braking Systems (AEBS) and Lane Departure Warning Systems (LDWS) for commercial vehicles. Moreover, it was adopted rules for a new generation of Child Restraint Systems (CRS) called "i-Size" and rules covering the safety of batteries fitted in electric vehicles. In December 2011, the Commission also proposed measures to tackle noise of all type of vehicles.

According to the Commission, the inclusion of these measures in the United Nations' International Agreement on vehicle construction will ensure that the same requirements are adopted not only by Europe, but also by other countries such as Japan, Russia and South Korea, hence reducing market entry barriers and facilitating trade between major automotive markets.

The EU is a Contracting Party to the UN's 1958 international Agreement on vehicle construction. This Agreement has currently 50 Contracting Parties (including the EU, Japan, Russia and Korea) and 127 annexed Regulations. The Regulations cover the approval of vehicles' safety and environmental aspects. Commission and Member States take part in the technical preparatory work of the Forum and the Commission exercises the right to vote in the Forum on behalf of the EU.
