What is the term used for adding together limits of multiple vehicles insured on a policy?

The term used for adding together limits of multiple vehicles insured on a policy is intrapolicy stacking. This concept is particularly important in auto insurance, where a policyholder may have several vehicles covered under a single insurance policy. When limits are stacked intrapolicy, the total coverage available can be increased, providing greater financial protection in the event of a loss.

Intrapolicy stacking allows the insured to utilize the coverage limits of each vehicle to create a cumulative limit across the entire policy, which can be beneficial during incidents that involve high-cost claims. This pooling of limits effectively maximizes the policyholder's protection and is beneficial for policies that are designed to cover multiple vehicles.

The other options refer to different concepts that do not apply here. Premium stacking refers to combining insurance premiums, which is unrelated to coverage limits. Interpolicy stacking would involve combining limits from multiple insurance policies, rather than within a single policy. Loss stacking does not accurately describe the concept of adding limits and is not a recognized term in this context. Thus, intrapolicy stacking is the correct term reflecting the addition of coverage limits for multiple vehicles covered under one policy.
