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.
How are traffic signs grouped in Iceland?
The regulation uses 100-series warnings, 200 priority, 300 prohibitions, 400 obligations, 500 special rules, and 600/700 information and guidance.

Is a temporary speed limit at roadworks binding in Iceland?
Where an authorised temporary regulatory speed limit is in force, you must obey it. A roadworks warning alone should not be mistaken for a new numerical limit, but conditions may require driving more slowly.
