Therefore, the maintenance programme takes due account of this. (b) Daily checks of signs need to focus on the functioning of the lamps, the legibility of inscriptions, damage to the sign panels, fading of the colours, and the removal of possible obstructions. During night inspections, the proper illumination of the signs is also checked. (c) Annual checks of signs include: (1) the mounting of both the sign and its lighting; and (2) the sign’s structure. (d) Unscheduled checks are necessary after weather phenomena that may affect the functioning of a sign, such as snowfalls to remove snow accumulation, storms that may have damaged the signs, etc. GM1 ADR.OPS.C.015(d);(f) Maintenance of visual aids and electrical systems ED Decision 2021/003/R MARKINGS AND SIGNS (a) An assessment of the condition of the signs and markings performed during the night when compared with an assessment performed during the daylight, allows determining the reflectivity of the marking.
