As the Traffic Signs Manual points out,the performance of reflective sheeting may degrade overtime,and it is therefore important to review the performance and quality.To remain compliant,traffic signs must continue to perform at the stipulated level.
Over time,signs gradually become faded and their retroreflective properties diminish.This will reduce both conspicuity and legibility by day and by night.Signs also become less effective when they are are dirty,damaged or displaced as a result of vehicle impact or vandalism.Damaged or dirty signs also discredit the traffic authority and lessen road users' respect for the signs.Aperiodic inspection of signs should be made to ensure their early repair and/or replacement when necessary.After-dark inspections should be made of lit and reflectorised signs,or a retroreflectometer may be used to measure the latter.
