Which of the following is NOT covered by the garage coverage form?

The garage coverage form is an insurance policy specifically designed for businesses in the automotive industry, such as garages, auto repair shops, and dealerships. This form typically provides coverage for a range of liabilities and property damages associated with the operation of these businesses.

Underinsured motorists coverage is a type of auto insurance that protects drivers when they are involved in an accident with another driver who has insufficient insurance to cover the damages. This coverage is intended for personal auto policies rather than garage coverage policies. Therefore, underinsured motorists are not a risk covered by the garage coverage form because the focus of this insurance is primarily on business-related activities, including liability for customer injuries and damage to customer vehicles while in the business's care.

The other options, including damage to customer vehicles, liability for customer injuries, and property damage to covered premises, are all explicitly addressed within the scope of the garage coverage form, making them part of the protections offered under this type of insurance policy.
