Mirrors on heavy commercial vehicles
About blind spot mirrors and vulnerable road users (VRU) detection systems
This content is for general information only. It does not, and is not intended to, provide legal or technical advice or to represent a legal interpretation of the matters it addresses.Many commercial vehicles e.g., trucks, buses etc. have large blind spots due to their sheer size and design. Class VI, cyclops or front blind spot mirrors are mirrors fitted to heavy commercial vehicles to remove the blind spot immediately in front of the vehicle. Pedestrian and cyclist detection (PCD) systems are specialized technologies that can be built into these vehicles to detect the presence of vulnerable road users and subsequently warn the driver.
Frequently asked questions
Class VI mirrors must be fitted to all commercial vehicles over 7,500 kg regardless of their age under S.I. No. 457 of 2011 with effect on 01 October 2012.
In certain vehicles where the driver has a clear view of the area in front of the vehicle a class VI mirror may not be required e.g., if the driver seat and cab are lower to the ground than a normal HCV the front blind spot may be sufficiently small enough so that an additional mirror is not required. If your vehicle requires a class VI mirror see HCV Manual for further guidance.
Yes. From 01 January 2013 failure to have HCVs with a design gross vehicle weight of over 7,500 kg fitted with a class VI or cyclops front mirror will result in a fail item at the periodic roadworthiness test. See our HCV Manual.
See HCV Manual in Mirrors section explaining angle, field of vision and adjustment.
No. The regulation governing the positioning of cyclops mirrors S.I. No. 457 of 2011 only applies to Irish registered trucks. It does not apply to foreign trucks travelling in Ireland.
Many commercial vehicles e.g., trucks, buses etc. have large blind spots due to their sheer size and design. PCD’s are specialist technologies which can be built into such vehicles to detect the presence of vulnerable road users i.e., pedestrians and cyclists and subsequently warn the driver.
There is currently no European or national legal requirement to have PCD systems fitted on HCVs.
