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.
How are traffic signs grouped in the United States?
The MUTCD distinguishes regulatory, warning and guide signs. State traffic law supplies the corresponding driver obligations.
Is a temporary speed limit at roadworks binding in the United States?
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.

This traffic sign means stop and give way. You must come to a complete stop before entering the intersection and give way to traffic that has priority. Proceed only when it is safe.
