A more thorough explanation:

Definition: Self-applying is an adjective used to describe a law or rule that can be easily understood without needing any special interpretation or explanation. It only requires a basic understanding of the words used in the law or rule.

Example: A speed limit sign that says "Speed Limit 50 mph" is an example of a self-applying law. Anyone who can read and understand English can easily understand that they should not drive faster than 50 miles per hour on that road.

Another example of a self-applying law is a "No Smoking" sign in a public area. The sign is clear and easy to understand, and anyone who sees it knows that smoking is not allowed in that area.

These examples illustrate how self-applying laws are straightforward and do not require any special knowledge or interpretation to understand.
