Hawaii Citizen's Guide to Auto Crash Insurance Calculations
This guide explains how a Hawaii citizen should analyze a serious crash: identify the at-fault liability stack, separate bodily-injury and wrongful-death claims from property claims, measure the effect of Hawaii's 20/40/10 liability floor, account for Hawaii's no-fault personal-injury-protection structure, apply Hawaii's comparative-fault rule, and then determine what uninsured, underinsured, rideshare, employer, or umbrella coverages may change the real calculation.

Hawaii crash-calculation frame
Hawaii is a no-fault state. The ordinary motor-vehicle package begins with at least $10,000 per person in personal injury protection, plus at least 20/40/10 in liability coverage: twenty thousand dollars for bodily injury or death to one person, forty thousand dollars for bodily injury or death to two or more persons in one accident, and ten thousand dollars for property damage in one accident.
Hawaii's no-fault system changes the first question after a crash. For bodily injury, the injured person's own PIP layer pays first, and tort liability is abolished unless a statutory threshold is crossed. Property damage remains fault-based. That means a Hawaii citizen must calculate two systems at once: the no-fault injury system and the fault-based liability system.
Minimum liability
20k bodily injury to one person, 40k bodily injury per accident, 10k property damage.
Required PIP
At least 10k per person in basic personal injury protection for appropriate and reasonable treatment and related covered losses.
No-fault threshold
Many bodily-injury claims cannot break out into tort unless death, serious permanent injury, serious disfigurement, or the 5k threshold is met.
Comparative fault
Hawaii allows recovery so long as the claimant's negligence is not greater than the negligence of the person or aggregate negligence of the persons against whom recovery is sought.
Coverage cues that matter immediately after a crash
| Coverage item | Hawaii cue | Why it matters |
|---|---|---|
| Liability BI | 20/40 minimum | Third-party bodily-injury and wrongful-death claims begin here only after the no-fault structure is properly measured. |
| Property damage | 10k minimum | Vehicle destruction, bicycles, child seats, electronics, and pet property claims compete inside a very small property-damage coverage. |
| PIP | 10k minimum | The first bodily-injury layer is not a tort case. It is the injured person's own PIP claim. |
| Tort threshold | Death, significant permanent loss of use, permanent and serious disfigurement, or 5k in qualifying PIP-incurred benefits | A claimant may be blocked from general damages until the statutory threshold is crossed. |
| UM/UIM | Meaningful offer-and-rejection structure with written rejection mechanics | The victim household's own declarations page and rejection forms may matter as much as the at-fault liability stack. |
| Covered-loss deductible | Judgment, settlement, or award reduced by 5k or the amount of PIP benefits incurred, whichever is greater, up to the limit | Even after a bodily-injury claim is allowed, the no-fault layer still changes the real recovery math. |
Coverage ladder: minimum through commercial
| Tier | Typical stack | What the citizen should assume |
|---|---|---|
| Tier 0 | Uninsured or no liability policy | No liability coverage exists. The victim household must look to retained UM/UIM, PIP, health coverage, direct claims against the driver or estate, and any employer or owner theories. |
| Tier 1 | Hawaii minimum PPA: 20/40/10 plus 10k PIP | This is the legal floor for ordinary personal auto coverage. In a fatality or major-trauma case it is often catastrophic and quickly exhausted. |
| Tier 2 | Common mid PPA: 35/70/10 or 50/100/25 plus 10k PIP | Still thin in a catastrophic case, but materially stronger than the floor. |
| Tier 3 | Common higher PPA: 100/300/100 plus retained UM/UIM | Often the first household-protection package that materially changes settlement posture. |
| Tier 4 | High PPA plus umbrella | Primary auto may be followed by umbrella or excess layers. Identifying all declarations pages matters. |
| Tier 5 | Commercial auto, employer fleet, or TNC stack | The whole claim changes if business use, employer coverage, or transportation-network coverage applies. |
Post-crash calculation roadmap
| Step | Question | Practical consequence |
|---|---|---|
| 1 | Who is claiming? | Separate the at-fault driver, family passengers, other vehicle occupants, pedestrians, bicyclists, and each item of damaged property. They do not stand in the same coverage position. |
| 2 | What kind of claim is it? | Human death or bodily injury starts with no-fault PIP analysis. Vehicle loss, bicycles, pets, electronics, and gear remain property-damage questions. |
| 3 | Has the tort threshold been crossed? | If the threshold is not met, the citizen may be confined to PIP and related first-party recovery for bodily injury rather than a full tort claim. |
| 4 | What is the at-fault stack? | Identify personal auto, umbrella, employer, rideshare, commercial, rental, or government layers before assuming the case is only minimum-limits. |
| 5 | What does the victim household carry? | Read the declarations page for retained UM/UIM, any optional increased PIP, collision, comprehensive, and any umbrella or excess layer. |
| 6 | How is fault allocated? | Hawaii reduces damages proportionately for claimant negligence but does not bar recovery unless claimant negligence is greater than the negligence against which recovery is sought. |
| 7 | How does the covered-loss deductible change the result? | Even after the claim clears the tort threshold, the bodily-injury recovery can be reduced by the statutory deductible tied to PIP-incurred benefits. |
Scenario 1: multi-fatality minimum-limits matrix
Hypothetical catastrophe: a drunk driver, traveling with a spouse, infant child, and family dog, crashes into another passenger car carrying two adults, one child, and that family's bicycle rack and gear. All humans are killed. These tables are educational illustrations, not litigation predictions.
| Claimant group | Claim type | Primary coverage to examine | Main threshold issue | Citizen takeaway |
|---|---|---|---|---|
| At-fault driver | Own bodily injury or death | Not a third-party liability claim against the driver's own liability policy | Liability insurance is not first-party death coverage for the at-fault driver. | Look first to PIP, optional first-party benefits, health coverage, or life insurance—not liability. |
| At-fault driver's spouse | Wrongful death or bodily injury claim against driver or estate | PIP first; possible tort claim because death breaks the no-fault shield | Competes with every other covered human claimant in the 40k accident aggregate unless other layers exist. | Even where the no-fault threshold is obviously crossed by death, the liability stack may still be tiny. |
| At-fault driver's child | Wrongful death or bodily injury claim against driver or estate | Same PIP-first and liability-after-threshold structure | No separate child coverage category exists inside the liability aggregate. | Children compete inside the same aggregate as adults once the claim leaves the no-fault gate. |
| Other car: adult 1 | Wrongful death | PIP first, then third-party bodily-injury or wrongful-death claim | Competes with every other covered human claimant in the 40k accident aggregate. | The per-accident aggregate can matter more than the 20k per-person figure. |
| Other car: adult 2 | Wrongful death | Same PIP-first and liability-after-threshold structure | Same aggregate competition | Clear fault still leaves one very small shared liability coverage. |
| Other car: child | Wrongful death | Same PIP-first and liability-after-threshold structure | Same aggregate competition | No separate child lane exists inside liability coverage. |
Property damage, bicycles, pets, and gear
| Item or loss | Usual coverage lane | What changes the analysis |
|---|---|---|
| Other family's vehicle | 10k property-damage coverage | Collision coverage on the victim side may pay first, but the liability property-damage limit still matters for reimbursement and total-loss pressure. |
| At-fault vehicle | Usually not a third-party property-damage claim against the at-fault driver's own liability policy | Look to collision or other first-party property coverages, not liability. |
| Bicycles, racks, helmets, child seats, electronics, luggage | 10k property-damage coverage | These items compete with the vehicle loss unless other first-party property coverage exists. |
| Pets | Property and economic-damage analysis, not wrongful-death analysis | The page should treat pets as property-damage items unless some other policy language changes the first-party side. |
| Property owned by, transported by, or in the charge of the insured | Outside ordinary third-party property-damage coverage | Hawaii's liability statute itself excludes property owned by, being transported by, or in the charge of the insured from ordinary third-party property-damage protection. |
Hawaii UM/UIM and no-fault structure
Hawaii's first-party structure is layered. Basic PIP pays first for bodily injury. Hawaii also requires a meaningful uninsured-motorist offer-and-rejection structure and a parallel underinsured-motorist structure, with written rejection mechanics and stacking options that must be offered. That means the victim household's declarations page and rejection forms can matter just as much as the at-fault liability stack.
But Hawaii is not a simple immediate-access UIM state. The no-fault threshold controls when many bodily-injury tort claims open. And once the claim moves into the UM/UIM space, Hawaii still imposes rules about exhaustion, same-household policy limits, and the covered-loss deductible.
| Your own coverage position | What happens after a severe crash | Citizen takeaway |
|---|---|---|
| PIP only at the minimum | The household has the required 10k first layer, but may still be badly exposed in a major trauma case. | Basic PIP pays bills; it does not solve the full bodily-injury problem. |
| UM/UIM retained | The victim household may have a meaningful first-party backstop if the at-fault driver is uninsured or underinsured. | The declarations page and rejection history matter immediately after the crash. |
| UM/UIM rejected | The first-party backstop may be gone or materially weaker than expected. | Proof of the written rejection matters as much as the declarations page. |
| Liability layer not yet resolved | The first-party gap analysis may remain uncertain until the liability layer is measured and settled. | Citizens cannot intelligently value the case without knowing both sides of the insurance picture. |
| Multiple same-household policies | Hawaii's stacking and highest-limit rules may sharply limit what a citizen assumed multiple policies would provide. | Do not assume easy stacking just because more than one vehicle or policy exists. |
Pedestrians and bicyclists
| Victim type | Human injury or death coverage | Property coverage | What changes the analysis |
|---|---|---|---|
| Pedestrian adult | PIP / no-fault analysis first, then possible third-party bodily-injury or wrongful-death claim if threshold is met | Clothing, carried items, devices | The claimant may need to prove threshold status before a full tort claim opens. |
| Pedestrian child | Same PIP-first and threshold structure | Stroller or carried items | No separate child coverage category exists inside liability coverage. |
| Bicyclist adult | PIP / no-fault analysis first, then possible third-party bodily-injury or wrongful-death claim if threshold is met | Bicycle, helmet, electronics, rack, or cargo | The rider's bodily injury is a BI claim; the bicycle and gear are property-damage claims. |
| Bicyclist child | Same PIP-first and threshold structure | Bicycle and gear | The bodily-injury and property claims still sit in different coverage lanes. |
| Pedestrian or bicyclist with retained UM/UIM | Possible first-party backstop after the no-fault and liability layers are measured | No automatic cure for ordinary property loss | The victim must know both the at-fault stack and the victim household's own declarations page and rejection status. |
Higher tiers, umbrella, work use, and TNC coverage
| Scenario | What changes | Why the calculation changes |
|---|---|---|
| Higher personal-auto tier (35/70/10, 50/100/25, 100/300/100) | Larger bodily-injury and property-damage coverages | A severe crash may still overwhelm the policy, but the collapse is less severe than at 20/40/10. |
| High personal-auto limits plus umbrella | Excess liability may sit above the primary auto policy | If umbrella exists, settlement posture, release strategy, and first-party gap analysis may change substantially. |
| Driver on the job | Employer auto, workers' compensation, or commercial-use questions may arise | The case may shift from a household policy to an employer or commercial stack. |
| TNC driver logged in but waiting | Hawaii requires at least 50/100/25 plus PIP while the driver is logged in and available | The waiting-period rideshare case already differs from an ordinary household policy. |
| TNC driver on a prearranged ride | Hawaii requires at least 1,000,000 in primary liability plus PIP while the ride is underway | The claim may be radically different from an ordinary 20/40/10 crash. |
| Personal auto during TNC activity | Personal auto might not provide required or optional coverage while the driver uses a personal vehicle in a prearranged ride | The ordinary personal-auto policy may disappear at exactly the moment a citizen assumes it still applies. |
Why disclosure still matters in Hawaii
Hawaii requires a motor vehicle insurance identification card to be carried, but that roadside proof card is not the declarations page. It does not tell a claimant the real story after a serious crash. It does not show whether the case is only a 20/40/10 personal-auto case, whether optional higher limits exist, whether umbrella coverage exists, whether a rideshare layer applies, or whether the injured household retained or rejected UM/UIM.
Your project materials also classify Hawaii as a no pre-suit duty state for third-party liability-limits disclosure. That means the claimant can still be pushed toward settlement or litigation without seeing the real insurance picture first. In Hawaii, that picture includes not only liability limits but also PIP, threshold issues, covered-loss deductions, UM/UIM retention or rejection, and possible rideshare or employer layers.
