UN R170 Bus and Coach CRS (from 20 Jun 2024)
<p>In 2008, Spain proposed the development of a UNECE Regulation to govern the installation and use of child restraint systems in M2 and M3 category vehicles (buses and coaches).</p> <p>The installation and use of seat belts in such vehicles is mandatory in Europe under Directive 2003/20/EC. However, this directive and the related UNECE Regulations only concern adults.</p> <p>Adult safety belts are not appropriate to restrain minors with a lower height than 135 cm and a lower weight than 36 Kg. Therefore, the use of safety belts for minors is not required under current regulations.</p> <p>Moreover, UNECE R44 on child restraint systems focuses on M1 vehicles and therefore fails to address child safety on buses.</p> Bus and Coach CRS Child Restraint Systems for Buses and Coaches UN Regulation No. 170 UN R170
