Round Signs for Prohibitions and Mandatory Instructions

Round traffic signs tell drivers about a prohibition, a restriction or a direction they must follow. Round signs with a red border show restrictions such as speed limits and no parking, while round signs on a blue background show mandatory directions. Because the message is given by a symbol or number, drivers understand it at a glance.

Sign Types

• Maximum speed limit signs: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110 and 120 km/h.
• Prohibition signs: no parking, no entry, no smoking and give way to oncoming traffic.
• Stop sign: for junctions and exits where vehicles must come to a full stop.
• Mandatory direction signs: turn right, turn left, keep right and keep left.
• Business sign: a round sign for shop and company branding.

Where Are They Used?

They are used to manage speed and traffic flow on private sites such as residential estate roads, car parks, factory and logistics yards, and school and hospital grounds. Low-speed areas typically use 10, 20 or 30 km/h signs. Pairing a speed limit sign with a speed bump helps drivers actually keep to the limit. On public roads, sign type and placement are decided by the road authority in line with the Turkish Traffic Signs Regulation. Signs can be mounted on a post, a wall or compatible delineators and barriers.
