Traffic signs

Traffic Sign Types, Sizes and Meanings

Traffic signs tell drivers and pedestrians, at a glance, what the road ahead looks like, which rule applies and where they are heading. In this category you will find road signs for highways, municipal streets, residential estates, car parks, factory yards and construction sites, together with the posts and stands to mount them. Ilgi Trafik manufactures its signs at its own factory in Akyurt, Ankara, so you can order signs from different groups and the matching posts in a single order.

Sign Groups and What the Shapes Mean

Traffic signs are read by shape and colour first: a driver knows what kind of message is coming before reading the symbol. Codes in our product names such as T-1a, TT-29, B-26, YB-1b or P-2 refer to the sign's designation in the Turkish General Directorate of Highways (KGM) system and make it easy to find the exact sign you need.

• Warning signs (T): White triangles with a red border that announce a hazard ahead, such as a dangerous bend, slippery road, pedestrian or school crossing, or a level crossing.
• Regulatory signs (TT): Prohibitions, restrictions and mandatory instructions, including speed limit signs, no entry, no overtaking and mandatory cycle lane signs. The stop sign is instantly recognised by its octagonal shape.
• Information signs (B, PL): Mostly blue square and rectangular signs for hospitals, fuel stations, bus stops, advance direction and lane selection, plus supplementary plates that complete the main sign.
• Road work signs (YB): Temporary signs with a yellow background for asphalt works, bridge repairs, lane shifts and road narrowing.
• Parking and no parking signs (P): No stopping and no parking signs, disabled and ambulance parking bays, visitor parking, car park direction and car park speed limit signs.
• Other warning and information signs: Site and facility warnings such as construction vehicles exiting, high voltage, no entry to the construction site and fall risk.

Sizes, Materials and Reflective Sheeting

Our signs are made from galvanized steel sheet, available in 1.5 mm or 2 mm thickness depending on the product. The galvanized coating protects the steel against rust outdoors. You can choose between two reflective sheeting grades: standard performance sheeting is sufficient for estate roads, car parks and low-speed areas, while high performance sheeting returns more headlight to the driver and is preferred on rural roads, at junctions and wherever night-time visibility is critical.

Round, triangular and octagonal signs are offered from 30 cm to 90 cm; square signs start at 30 cm; rectangular signs come in common sizes such as 50×75, 60×90 and 90×120 cm, with much larger formats available for direction and information signs. Choose the size according to road speed and viewing distance: higher speeds need larger signs, while smaller signs usually suit car parks and private sites.

Posts, Installation and Regulations

Galvanized omega posts and round tube posts are used for permanent installations, and portable sign stands for temporary work. The sign type, size and position should follow the principles of the Turkish Highway Traffic Regulation and the KGM traffic signs manual. On public roads, signage is the responsibility of the relevant road authority; on private property, using the same sign language helps drivers recognise signs the way they are used to.

Frequently Asked Questions

Which sheet thickness should I choose? 1.5 mm galvanized steel is widely used for car parks, estates and factory sites. For large signs, wind-exposed locations or roadside use, 2 mm steel is the sturdier choice.

What is the difference between standard and high performance sheeting? Both reflect headlights back to the driver at night. High performance sheeting looks brighter and makes the sign noticeable from further away, so it is recommended for high-speed roads and critical locations.

Can I buy the sign together with a post? Yes. Omega posts, tube posts and portable stands from the Traffic Sign Poles and Legs group can be added to the same order.
