Anti-Stacking Provision

A clause in insurance policies that prevents policyholders from combining or "stacking" coverage limits from multiple policies or vehicles to increase their claim payout. This provision limits the total amount an insurer will pay regardless of how many policies the insured person holds.

Example

“Due to the anti-stacking provision in her auto policy, Maria could only claim the $100,000 limit from one vehicle even though she owned three cars with identical coverage.”

Memory Tip

Think 'anti-stacking' like a store policy that says 'no double-stacking coupons' - you can't combine multiple discounts, just like you can't combine multiple coverage limits.

Why It Matters

This provision significantly affects how much compensation you can receive after an accident, potentially leaving you with less coverage than expected. Understanding anti-stacking rules helps you make informed decisions about purchasing adequate insurance limits and additional coverage options.

Common Misconception

Many people believe that owning multiple vehicles with insurance automatically means they have access to combined coverage limits from all policies. In reality, anti-stacking provisions often limit payouts to a single policy's limits, regardless of how many vehicles or policies you maintain.

In Practice

John owns two cars, each insured for $50,000 in uninsured motorist coverage. He suffers $80,000 in damages from an uninsured driver. Without anti-stacking provisions, he might expect $100,000 in total coverage ($50,000 × 2). However, with an anti-stacking clause, his insurer will only pay the $50,000 limit from one policy, leaving him $30,000 short of full compensation.

Etymology

The term comes from the concept of "stacking" multiple items on top of each other, combined with "anti" meaning against, originating in insurance law during the mid-20th century.
