Mandatory Instruction Signs are what color?

Explanation:
Mandatory instruction signs use a red background to signal actions that must be followed. The red color conveys immediacy and prohibition, making it clear that a directive is mandatory for pilots or vehicle operators, such as stopping or holding short. The bold red background helps the sign stand out so it’s obeyed immediately. Other colored signs are used for information or directional guidance, not for mandatory commands, which is why red is the correct choice here.
