Traffic signs

A traffic sign is a standardised visual symbol placed along roads to guide, warn, or regulate drivers, cyclists, and pedestrians. These signs provide essential information about road conditions, rules, directions, and potential hazards, helping to ensure safety and smooth traffic flow. They come in various shapes and colours—such as triangular warning signs, circular prohibitory or mandatory signs, and rectangular information signs—each designed for quick recognition and clear understanding.
