Artikel 29 bis Verdrag inzake verkeerstekens

Article 29 bis 1 When permanent road markings are to be modified for a specific period, in particular because of road works or diversions, temporary markings shall be applied in colours different from the colours used for permanent markings. 2 Temporary markings shall take precedence over permanent markings and road users are required to conform to them. When the simultaneous presence of permanent and temporary road markings could be a source of confusion, the permanent markings shall be covered over or removed. 3 Temporary markings shall preferably be retroreflective and may be supplemented by beacons, cats eyes or reflectors with a view to improving traffic guidance.
