A _________________ tells you about the laws that you must obey.

The correct answer is regulatory sign. Regulatory signs are crucial for informing drivers about specific laws and regulations that must be followed while on the road. These signs are often designed with a white background and may include red lettering to indicate prohibitions or commands, such as "Stop," "Yield," or speed limit signs. Their primary purpose is to ensure the safety of all road users by providing clear instructions regarding what is legally required.

By adhering to regulatory signs, drivers can help maintain order and safety in traffic, reducing the likelihood of accidents and violations. Understanding and obeying these signs is fundamental for responsible driving and is a key component of safe roadway behavior.

In contrast, warning signs alert drivers to potential hazards ahead but do not dictate laws. Informational signs provide guidance or informational resources, while directional signs help with navigation and route finding.
