Which category of traffic signs includes legal offenses for non-compliance?

Regulatory signs are a critical category of traffic signs that convey laws and regulations that drivers must follow. These signs are designed to inform road users about legal obligations, such as speed limits, stop signs, yield signs, and no-parking zones. Non-compliance with these signs can lead to legal consequences, including fines or penalties, as they indicate mandatory actions that all drivers must adhere to in order to ensure safety and order on the road.

In contrast, warning signs serve to alert drivers to potential hazards or changes in road conditions but do not impose legal requirements. Guide or informative signs, such as those indicating directions or points of interest, provide helpful information but are not enforceable by law. Directional signs primarily assist with navigation and do not relate to legal compliance in the same way as regulatory signs do. Therefore, regulatory signs represent the category where non-compliance can lead to legal offenses.
