Road Maintenance and Repair Boards

Road Work and Maintenance Signs

Road maintenance and repair signs are temporary signs used to guide traffic safely during road construction, maintenance and excavation work. Most have a yellow background, which tells drivers the sign belongs to a temporary arrangement and overrides permanent signs. Alongside the YB-coded signs of the Turkish KGM system, this category includes the warning and regulatory signs used within work zones.

Signs Used in Work Zones

• Work notices: Asphalt works, bridge repair, road works ahead, excavation works and municipal asphalt work information signs.
• Lane management: Road narrows and lane shift signs, two-way lane arrangement signs and road works keep right signs.
• Site exits: Caution construction site, caution vehicles exiting and caution construction vehicles exiting signs.
• Speed and overtaking rules: Work zone speed limits, end of no overtaking, end of speed limit, end of all restrictions and stop signs.
• Roadside and other warnings: Shoulder marker flag signs, low shoulder, loose gravel, slippery road and uneven road signs.

Sizes, Material and Use

Square maintenance signs are mainly offered in 90 cm and 100 cm, while larger information signs come in wide rectangular sizes depending on the content. Signs are produced on 1.5 mm or 2 mm galvanized steel with standard or high performance reflective sheeting; for work that continues at night, high performance sheeting is recommended. For temporary work, signs are set up on portable stands, and combined with traffic cones, warning lights and road barriers they make the work zone clearly visible from a distance. Turkish traffic law requires those working on the road to mark the work area, and the KGM traffic signs manual is the reference for layout.

Frequently Asked Questions

Why are road work signs yellow? The yellow background shows that the sign is temporary and will be removed when work ends. During this period drivers must follow the yellow signs instead of the permanent ones.

Which signs are needed for municipal excavation work? Typically a work notice sign, a lane narrowing sign and a work zone speed limit sign are used together, with additional warning signs depending on the road layout.
