Traffic signs that give orders are generally circular in shape. Most importantly, these circular signs often have a red border indicating prohibitive commands (what you must not do), such as speed limits, no entry, no overtaking, and other restrictions. There are also blue circular signs which indicate mandatory actions (what you must do), like turn left or keep left. Additionally, some special order-giving signs include the octagonal "stop" sign and the triangular "give way" sign , which are exceptions designed to stand out for their importance. In summary:
- Circular signs with a red border give prohibitive orders.
- Circular signs with a blue background give mandatory orders.
- The stop sign is octagonal.
- The give way sign is triangular with a red border.
These shapes and colors are standardized to ensure drivers recognize orders immediately and obey them for safety and legal compliance.
