Cycle safety mirrors (“trixi mirrors”) must currently be authorised by the Secretary of State for Transport, Justine Greening, because they are not prescribed within the Traffic Signs Regulations and General Directions 2002 (TSRGD).
Trixi mirrors were authorised initially at certain sites as part of a trial on Transport for London Cycle Superhighway. To further assist monitoring of their effectiveness, the authorisation is being applied across the whole Cycle Superhighway Network.
The Department intends to update TSRGD following the publication in October of the traffic signs policy review 'Signing the Way':
Based on the outcome of the current trials, we will consider the suggestion my hon. Friend makes regarding trixi mirrors as part of this update, which is expected to conclude in 2014.
