Final answer:
Regulatory signs are the type of road signs that give notice to road and traffic laws or regulations. They are essential for safety and include signs like speed limits and stop signs.
Step-by-step explanation:
The type of signs that give notice to road and traffic laws or regulations, imposing legal obligations and/or restrictions on all traffic are known as regulatory signs. These signs are essential for informing drivers and pedestrians of the traffic laws that must be followed, such as speed limits, no parking zones, and right-of-way rules. Regulatory signs are designed to ensure the safety and efficiency of roadways by guiding driver behavior. For instance, a sign indicating a speed limit enforces a legal restriction on driving speeds to prevent accidents and facilitate safe traffic flow. Similarly, a stop sign at an intersection requires all vehicles to come to a complete stop, ensuring that crossing paths can be navigated safely.
