Electrical Engineering (EE) Laws Practice Exam

When a regulation is published in the Official Gazette, the rules often specify an exact waiting period before it becomes enforceable. For this Code of Ethics, that period is fifteen days. So the code doesn’t take effect on the publication date; it becomes enforceable on the fifteenth day after publication. This gives people time to learn about the new requirements and to prepare to comply.

If it were published on a certain date, simply add fifteen days to reach the effective date (for example, publication on a Monday would shift the enforcement date to fifteen days later, counting the days after publication). The other options would either shorten or extend the waiting period beyond what the regulation sets, which is why they aren’t correct.
