Which of the following is an example of a regulatory sign?

Regulatory signs are essential components of traffic management, designed to inform drivers of specific laws and regulations they must obey while on the road. These signs help maintain order and safety by providing clear instructions regarding the behavior expected from drivers.

The stop sign is a clear example of a regulatory sign, as it requires vehicles to come to a complete stop at an intersection. The yield sign also fits into this category because it instructs drivers to give way to incoming traffic, enhancing safety and flow. Additionally, speed limit signs are crucial regulatory signs because they inform drivers of the maximum legal speed allowed on a particular stretch of road, which is vital for road safety.

Since all the options provided—stop signs, yield signs, and speed limit signs—are regulatory signs that enforce specific driving behaviors, the correct response encompasses all of these examples. This highlights the critical role of regulatory signs in guiding driver behavior and ensuring compliance with traffic laws for the safety of all road users.
