Liability only and full coverage

What the coverage words mean

Liability coverage pays for injury and property damage the policyholder causes to somebody else. It is the part that mandating states require, and it pays nothing at all towards the policyholder’s own vehicle or their own injuries.

The phrase full coverage appears in no statute. In ordinary use it means liability plus comprehensive, which covers non-collision damage such as theft, hail, flood and glass, plus collision, which covers impact damage to the insured vehicle regardless of fault. Some people also fold in medical payments, personal injury protection and uninsured motorist coverage, which is why the phrase cannot be relied on to mean one fixed thing.

Uninsured and underinsured motorist coverage sits awkwardly between the two categories. It pays the policyholder, but for somebody else’s fault. Several states require it, or require insurers to offer it and take a written rejection, so it frequently appears inside a survey’s coverage package without being described as part of full coverage at all.

Deductibles are part of the price

Comprehensive and collision each carry a deductible, and the deductible is a lever on the premium rather than a footnote. A survey specifying a low collision deductible and a survey specifying a high one are describing different products, even where both call the package full coverage.

Regulators publishing full-coverage surveys therefore fix the deductibles in the profile definition and print them. Where a single insurer answered at a different deductible from the rest, the department says so in its own notes, and that note travels onto the page here rather than being smoothed away for tidiness.

Liability limits behave differently from deductibles, and the difference is easy to miss. A deductible changes what the policyholder pays before the insurer pays anything, on every comprehensive or collision claim. A liability limit changes only the ceiling on a claim, and most claims never approach the lower ceiling, which is why raising a limit costs proportionally far less than the limit multiplies.

Why two surveys are not comparable

One state’s survey may rate state-minimum liability only, with no deductible anywhere in the profile and no coverage for the insured vehicle. Another’s may rate full coverage with fixed comprehensive and collision deductibles, personal injury protection, and uninsured motorist limits well above the statutory floor. Both are correctly labelled and neither is wrong. They are simply not the same purchase.

Policy term compounds the problem. 6 of the jurisdictions here publish six-month premiums and 7 publish annual premiums, so a liability-only six-month figure and a full-coverage annual figure differ on two axes at once. This site never places figures from two states in one table, and prints the coverage package and the term beside every number.

What the spread looks like inside one package

Holding coverage constant narrows the answer far less than most readers expect. In San Francisco - Glen Park, California, one profile published by the California Department of Insurance carries 48 filed annual rates running from $5,258 to $220,416, with a median of $12,512. Identical coverage, identical driver definition, one geography, and that is still the width of the answer.

The coverage label is therefore the first question rather than the last one. It tells a reader what is being priced. It does not tell them what the price is, because the filed rates for one fully specified package still spread across a range no single figure summarises.

Questions

Is full coverage a legally defined term?

No. No statute defines it. It is shorthand for liability plus comprehensive and collision, and the deductibles and any additional coverages vary with whoever is using the phrase.

Can a liability-only survey figure be read beside a full-coverage one?

No. They price different products, and the two states involved may also publish over different policy terms, 6 of the jurisdictions here being six-month and 7 annual.

Does more coverage always cost proportionally more?

Not proportionally. Raising a liability limit increases the filed premium by far less than the limit multiplies, because most claims never reach the lower limit in the first place. The distribution tables show the effect for each profile a regulator publishes.
