- "Full coverage" isn't a policy — it's liability + comprehensive + collision stacked together.
- A common rule of thumb: when annual full-coverage premium passes ~10% of vehicle value, dropping collision often deserves a second look.
- In hail-prone Washington County, keeping comprehensive — even on older vehicles — frequently pays for itself in a single storm.
- State-minimum liability (30/65/25) and dropping comp/collision are two separate decisions that often get confused in St. George.

"Just give me the cheap one" is a request we hear a few times a week in our St. George office. Sometimes that's the right call. More often, the cheapest legal policy in Utah leaves a Saint George household one bad afternoon away from a five- or six-figure out-of-pocket loss. Here's the math we actually walk people through.
Pricing in this guide is illustrative — based on real quotes we've run in St. George this year. Your actual premium depends on your driver record, vehicle, credit, household, and the specific carrier and policy form. This is general information, not a quote or a promise of coverage.
"Full coverage" isn't a thing — it's three policies stacked
The phrase "full coverage" is industry shorthand for liability + comprehensive + collision on the same policy. Each piece does something different:
- Liability (required in Utah, minimum 30/65/25): Pays for damage YOU cause to other people and their property. Pays nothing toward your own vehicle. See our Utah auto insurance minimums guide for what those numbers actually mean. Utah's statutory limits are codified at Utah Code §31A-22-304.
- Comprehensive (optional unless required by a lender): Pays for hail, theft, fire, vandalism, animal strikes, falling objects, broken glass — anything that isn't a collision.
- Collision (optional unless required by a lender): Pays for damage to your own vehicle when you hit something (or get hit), regardless of fault. The Insurance Information Institute has a clean breakdown of how comp and collision differ.
"Liability-only" or "cheap" Utah car insurance drops the last two. If you wreck your own car, you pay for it.
Liability vs full coverage vs liability + comprehensive — side by side
| What it pays for | Liability-only (Utah min) | Liability + Comprehensive | Full coverage |
|---|---|---|---|
| Damage you cause to others | ✅ (30/65/25) | ✅ | ✅ |
| Hail, theft, fire, animal strikes | ❌ | ✅ | ✅ |
| Your own car after a crash | ❌ | ❌ | ✅ |
| Required by a lienholder? | No | No | Yes |
| Typical St. George cost/mo* | $45–$85 | $55–$100 | $95–$180 |

The 10-percent rule we use in St. George
The simplest test we walk clients through: if your annual full-coverage premium exceeds about 10% of your vehicle's actual cash value, dropping collision is worth a hard look — assuming you could absorb the loss out of pocket. Example: a 2010 Honda Civic worth $5,500 with $750/year of full coverage on it. You're paying 13.6% of the car's value every year to insure it. After three clean years you've paid more in premium than the car is worth. Liability-only saves $40–$70/month, and a total loss costs you the car — which you could replace with one year of saved premium.

How to run the 10% test on your own policy
- Pull your declarations page and find the annual premium for each vehicle.
- Look up your vehicle's actual cash value on Kelley Blue Book or NADA (private-party value, not retail).
- Divide annual premium by vehicle value. Over ~10%? Drop-collision conversation is worth having.
- Decide whether you could write a check for the car tomorrow if it were totaled. If yes, liability + comprehensive is on the table.
- Call us at (435) 628-0993 and we'll re-quote both versions side by side with no obligation.
Comprehensive is the piece St. George drivers shouldn't drop
Hail is the reason. Washington County took 600+ auto claims from a single 2023 storm in 84780 (see our hail season guide). Comprehensive — the "other than collision" coverage — is what pays for hail, and it's also cheap: typically $4–$12/month per vehicle in St. George. Dropping comprehensive on a paid-off vehicle to save $8/month, and then losing the vehicle to a summer storm, is the most common preventable claim we see.
What we usually walk older-vehicle clients through in St. George: drop collision, keep comprehensive. You self-insure the at-fault crash (because the car isn't worth much), but the carrier still pays if hail, a deer on Bluff Street, or a theft takes it.
When liability-only is the wrong conversation
Going liability-only on the vehicle and going to state-minimum liability limits are two different decisions. We see them confused constantly. State minimum 30/65/25 leaves a lot of exposure for a homeowner — see our Utah minimums explainer. If you own a home in Bloomington, Little Valley, Sun River, or anywhere in Washington County, the conversation most of our clients land on looks like:
- Higher liability limits (often something like 100/300/100) — typically only $10–$25/mo more than state minimum, depending on profile
- Uninsured/underinsured motorist limits that match the liability limits
- Comprehensive kept on every vehicle
- Collision evaluated vehicle-by-vehicle using the 10% rule above
This kind of policy is often only $15–$45/month more than a bare-minimum liability-only policy — and the spread is usually the difference between a fender-bender being a $500 inconvenience and a bad accident becoming a years-long financial setback. Specific limits and pricing should always be decided with a licensed agent based on your assets and household.
Bundling and the 10% conversation
One quiet way the math changes: if you bundle auto with your homeowners or renters policy, the per-vehicle premium usually drops 8–25%. That can push a borderline "drop collision" vehicle back into "keep it" territory. We walk through the numbers in our bundle auto + home in St. George guide.
