Which of the following is NOT insurable with the Windstorm Underwriting Association?

The Windstorm Underwriting Association (WUA) is an organization that provides coverage for properties located in regions prone to windstorm damage, specifically in areas at high risk for hurricanes and tropical storms. This typically includes residential, commercial, and industrial properties that are subject to loss due to wind-related events.

Motor vehicles, however, are not covered under the Windstorm Underwriting Association. Coverage for vehicles is generally provided through different types of auto insurance policies rather than property insurance, which the WUA focuses on. Therefore, the identification of motor vehicles as not insurable with the WUA is accurate, as it does not fall within the scope of property insurance that the association offers. The other types of properties listed are included under the purview of windstorm coverage, making motor vehicles the exception.
