Which of the following statements is true regarding the validity of the director's orders?

The correct choice emphasizes that only written and signed orders from the director are deemed valid. This requirement ensures that there is a clear and official record of the directives issued by the authority, which is crucial for maintaining transparency and accountability in regulatory practices.

Written orders provide a definitive basis for compliance, allowing those affected by the orders to understand the terms and conditions clearly. This formality is important in regulatory contexts, where ambiguity could lead to disputes or misinterpretations. By requiring orders to be signed, it serves as a confirmation of the director’s authority and intention, further solidifying the legitimacy of the order.

While there are scenarios where verbal orders may be relevant, such as emergencies, those do not hold the same weight as written orders in terms of enforceability and record-keeping. Retaining a formalized process through written communication is vital for both the integrity of the regulatory framework and the protection of the rights of all parties involved.
