What type of coverage under ABC's garagekeepers policy would address any part of the loss not covered by Jim's comprehensive policy?

The correct choice is Direct Excess Coverage, as it specifically refers to a type of insurance that applies in situations where losses exceed the limits provided by a primary policy, such as Jim's comprehensive policy. In the context of the garagekeepers policy, Direct Excess Coverage will cover losses that are not fully addressed or are beyond the coverage limits of Jim's policy.

This type of coverage is particularly useful when dealing with claims that might involve shared responsibilities or when the primary insurance does not fully cover the damages or losses incurred. Therefore, if there is a loss that Jim's comprehensive policy does not fully address, Direct Excess Coverage would step in to fill that gap, providing the required financial protection up to the limits established under ABC’s garagekeepers policy.

Other options do not serve this specific function: Direct Coverage refers to the standard coverage for losses that are within the limits of the primary policy, General Liability Coverage protects against third-party claims for bodily injury or property damage, and Exclusion Coverage identifies what is not covered under a specific policy. None of these options would address any residual loss after Jim’s comprehensive policy is applied.
