Final answer:
When dealing with an overly large SVAN or ESAN, requesting a smaller one is normally the best approach, ensuring compliance with safety and legal standards. An exception should only be considered if it does not pose risks.
Step-by-step explanation:
If the Standard Vehicle Accommodation Note (SVAN) or Exceptional Size Accommodation Note (ESAN) is too large, the appropriate course of action would typically depend on specific circumstances, regulations, and company policies. However, from a general business standpoint, requesting a smaller one is usually the most professional and safest approach. If the size could potentially violate safety or legal regulations, it is necessary to refuse transportation. While an exception might be considered, it should only be done under circumstances where it will not compromise safety, legal, or business integrity. Making exceptions should generally be a last resort and done according to a well-established protocol.
