Miss this in your policy, and the bad surprise comes after the crash: you think several coverage limits can be added together, but the insurer says only one limit applies. Anti-stacking is policy language meant to stop you from combining insurance coverage from more than one vehicle, policy, or coverage part for a single loss. The fight usually comes up with uninsured motorist coverage, underinsured motorist coverage, medical payments coverage, or similar benefits. Without anti-stacking, a person might try to "stack" limits and collect more. With anti-stacking, the insurer argues the payout is capped at one policy limit.

That matters because people often assume paying premiums on two cars means two pots of money are automatically available. Not so. If an ice storm drops branches or power lines onto a Vermont road and a wreck involves an uninsured or underinsured driver, anti-stacking language can sharply reduce what is available for injuries. The clause may affect whether there is enough coverage for surgery, lost wages, or long-term care.

For an injury claim, the key question is not what the adjuster says over the phone, but what the policy actually says and whether Vermont law allows that restriction. In Vermont, 23 V.S.A. § 941 (2024) governs uninsured and underinsured motorist coverage, and disputes over anti-stacking often turn on the policy wording and how that statute applies. A lawyer will usually compare every policy, every vehicle listed, and every coverage part before accepting "one limit only" as the final answer.
