Florida is one of the few states that allows “stacking” of Uninsured and Underinsured Motorist (UM/UIM) coverage — and understanding the difference is one of the most important insurance decisions a Florida driver can make.
How stacking works: If you have two vehicles on the same policy, each with $100,000 in UM coverage, stacked coverage combines those limits — giving you up to $200,000 in UM protection per incident. With three vehicles at $100,000 each, you’d have $300,000 stacked. Non-stacked coverage caps you at the single per-vehicle limit regardless of how many vehicles are on your policy.
What about a single vehicle? Even on a single-car policy, electing stacked UM coverage is worth understanding. In some cases it provides broader coverage terms under Florida law, and it preserves your ability to stack should you add a vehicle in the future.
Why this matters in Florida: With one of the highest uninsured driver rates in the nation, Florida roads carry real risk. If an uninsured or underinsured driver seriously injures you or a family member, your UM/UIM coverage may be the primary — or only — source of financial recovery available to you. Stacked coverage maximizes that protection.
Cornerstone’s guidance: We educate every client on the difference between stacked and non-stacked UM/UIM so you can make an informed choice. Rejecting UM coverage or selecting non-stacked limits is a decision that deserves a full conversation with your licensed agent about the real-world risks involved. We’re here to help you understand those risks — not just check a box.
