All regulatory devices on the road instruct you:

• A. Follow the law
• B. Drive as you wish
• C. Speed as allowed
• D. Ignore the signs

Answer: (A)

Regulatory devices on the road tell you what you must do by law. They set enforceable rules—like stopping at a red light, obeying posted speed limits, or yielding at crosswalks—so everyone follows the same expectations and safety is maintained. When you see these devices, the instruction is to follow the law, not to decide your own course of action. Driving as you wish ignores these commands and can lead to accidents and legal penalties. Saying you can speed as you want ignores the specific limits shown, which regulatory signs and signals establish. Ignoring signs undermines safety and is illegal. So the idea these devices convey is clear: you must follow the law.
