Ohio's 51% Comparative Negligence Rule: How Shared Fault Affects Your Injury Claim
Think you're partially at fault for your accident? Under Ohio law, you can still recover damages—but only if you're less than 51% to blame. Here's exactly how this rule works and what it means for your injury claim.
A rear-end collision on I-71 near Columbus leaves you with a herniated disc and $43,000 in medical bills. The other driver was texting, but you were going seven miles over the speed limit. Can you still recover compensation? Under Ohio Revised Code 2315.33, the answer is yes—as long as your share of the blame stays below 51%. That threshold makes Ohio one of 33 states using a modified comparative negligence system, and understanding where that line falls can mean the difference between full recovery and walking away with nothing.
Ohio didn't always operate this way. Before 1980, the state followed a harsh contributory negligence doctrine: if you bore even 1% of the fault, you recovered zero dollars. The General Assembly reformed the law in 1980, adopting the 51% bar rule to balance fairness for plaintiffs against protection for defendants. Today, insurers weaponize this statute in settlement negotiations, arguing every misstep you made to push your fault percentage past the threshold. Knowing how courts assign blame—and how to defend against inflated fault allegations—protects your right to compensation.
What the 51% Rule Actually Says
Ohio Revised Code 2315.33 states that a plaintiff may recover damages "only if the plaintiff's percentage of fault is fifty percent or less" relative to all other parties. Cross that line to 51% or higher, and recovery drops to zero—not reduced, eliminated. The statute further requires that any award be diminished in proportion to your share of fault. If a jury finds you 30% responsible for a collision and awards $100,000, you collect $70,000.
This framework applies across virtually all personal-injury contexts in Ohio:
- Car Accidents: Speeding, failure to signal, distracted driving, and lane violations all factor into comparative fault calculations.
- Truck Accidents: Commercial-vehicle cases often involve multiple defendants—the driver, the carrier, the shipper—each with separate fault percentages that combine to determine your recovery.
- Motorcycle Accidents: Lane-splitting (legal in some states but frowned upon by Ohio juries), high speeds, and visibility issues frequently become fault arguments.
- Slip and Fall: Property owners argue you were distracted by your phone, ignored warning signs, or wore inappropriate footwear.
- Wrongful Death: Comparative fault can apply even to deceased victims; insurers may claim the decedent's actions contributed to the fatal incident.
The key phrase is "percentage of fault." Courts don't apply vague labels like "mostly responsible" or "somewhat to blame." Juries receive special verdict forms asking them to assign a specific number—0% to 100%—to each party, and those numbers must total 100%.
How Fault Percentages Get Assigned
Judges don't pull these numbers from thin air. In every contested case, the jury hears evidence on each party's conduct, evaluates which actions breached a duty of care, and decides how much each breach contributed to the harm. Ohio courts use a multi-factor test:
- Breach of duty: Did the party violate a traffic law, safety regulation, or general standard of reasonable care?
- Causation: Did that breach directly contribute to the accident and resulting injuries?
- Comparative severity: How serious was each party's breach relative to others involved?
Consider a head-on collision on State Route 2 near Toledo. Driver A drifted across the centerline while reaching for a coffee cup. Driver B was traveling 15 mph over the posted limit. Both actions violated duties of care—ORC 4511.25 (marked lanes) and ORC 4511.21 (speed limits)—but a jury might find Driver A's lane departure the more direct cause of impact and assign 70% fault to A, 30% to B. Driver B can still recover 70% of proven damages; Driver A recovers nothing because 70% exceeds the 51% threshold.
Police reports influence these calculations heavily. When an officer cites one driver under ORC 4511.43 (right-of-way at intersections) or ORC 4511.31 (failure to yield), that citation becomes evidence of negligence per se in a civil case. Yet citations aren't conclusive. Dashcam footage, witness statements, accident-reconstruction testimony, and vehicle data recorders all factor into the final determination.
Multiple Defendants and the Math That Follows
Truck Accidents involving commercial carriers often bring multiple defendants into a single lawsuit: the truck driver, the trucking company (via respondeat superior), the maintenance contractor, the cargo loader. Ohio law allows the jury to assign separate fault percentages to each. Suppose the jury finds:
- Truck driver: 40% (violated hours-of-service regulations under FMCSA 395.3)
- Trucking company: 20% (negligent hiring/supervision)
- Plaintiff: 25% (following too closely)
- Third-party passenger car: 15% (unsafe lane change)
The plaintiff's 25% fault stays below 51%, so recovery proceeds. If total damages equal $500,000, the plaintiff collects $375,000 (75% of the award). Each defendant pays according to Ohio's joint-and-several liability rules, which were modified by tort reform in 2005 to limit joint liability in many contexts.
The Harsh Cliff at 51%
Other states use a 50% bar (Wisconsin, Arkansas) or pure comparative negligence (California, New York, where plaintiffs recover even at 99% fault, though the award shrinks proportionally). Ohio chose the 51% threshold as a middle ground, but that creates a binary outcome: 50% fault yields a reduced recovery; 51% yields nothing.
Insurance adjusters exploit this cliff during settlement negotiations. A defendant's carrier might open with an offer of $15,000 on a $200,000 claim, asserting you bear 60% of the fault based on a police report notation that you "appeared distracted." Their goal is twofold: anchor your expectations low and pressure you to settle before depositions and discovery reveal the true fault picture. Many claimants without legal representation accept these low offers, unaware that disputed fault is a jury question, not a pre-trial certainty.
Real-World Example: The Cincinnati Crosswalk Case
In a 2019 Franklin County case, a pedestrian was struck in a marked crosswalk in downtown Cincinnati by a driver turning right on red. The driver's insurer argued the pedestrian was jaywalking (she wasn't—she was in a marked crosswalk with the signal) and wearing dark clothing at dusk, assigning 55% fault to her. Depositions revealed the driver had glanced at a navigation screen mid-turn, and city traffic-camera footage confirmed the pedestrian had the right-of-way. At trial, the jury assigned 85% fault to the driver, 10% to the city for inadequate crosswalk lighting, and 5% to the pedestrian for wearing non-reflective clothing. The plaintiff recovered 95% of a $380,000 verdict—$361,000—because her 5% fault stayed well below the 51% bar.
Had the plaintiff accepted the insurer's pre-suit offer of $22,000 (based on the inflated 55% fault claim), she would have left more than $330,000 on the table.
Seat Belts, Helmets, and Ohio's Mitigation Rules
Ohio Revised Code 4513.263 requires seat-belt use in passenger vehicles. When an unbelted plaintiff suffers injuries in a Car Accident, can the defendant reduce the award by arguing the plaintiff's failure to buckle up contributed to the harm? The statute itself says evidence of non-use is inadmissible to prove comparative negligence—but it is admissible to show failure to mitigate damages.
This distinction matters. Comparative negligence affects whether you recover at all (the 51% question). Mitigation affects how much you recover by isolating injuries that the seat belt would have prevented. A biomechanics expert might testify that wearing a belt would have eliminated the plaintiff's rib fractures but not the cervical sprain. The jury then reduces the award only for the rib-related medical bills and pain.
Motorcycle cases see similar arguments. Ohio has no universal helmet law (only riders under 18 or those with a novice license must wear helmets under ORC 4511.53), but insurers still argue that a bare-headed rider's traumatic brain injury would have been less severe with a helmet. Courts allow this as a mitigation argument, not a comparative-fault argument.
How Insurers Inflate Your Fault Percentage
Defense strategies to push you over 51% follow predictable patterns:
- Cherry-picking police-report language: An officer's narrative might say "both drivers claim the other ran the red light." The insurer highlights "both drivers," ignoring intersection-camera evidence that supports your version.
- Mischaracterizing traffic laws: An adjuster might claim you violated ORC 4511.202 (slow speed impeding traffic) when you were simply driving the posted limit in heavy rain.
- Exaggerating reaction-time failures: Accident reconstructionists hired by defendants often testify that a plaintiff "should have" braked sooner, even when perception-reaction studies show the plaintiff's response fell within normal human limits (1.5 seconds per NHTSA research).
- Weaponizing minor code violations: A burned-out taillight or expired registration becomes "evidence of general disregard for safety," though these administrative issues have zero causal link to the crash.
- Blaming road conditions you didn't create: A defense expert argues you drove too fast for icy conditions, omitting that the defendant was traveling 20 mph faster on the same road.
Countering these tactics requires evidence marshaling: dashcam footage, cell-tower records to disprove distraction claims, maintenance logs showing your vehicle was roadworthy, weather data from the National Weather Service, and expert testimony on human factors.
Comparative Fault in Slip and Fall Cases
Premises-liability claims under Ohio law require proof that the property owner knew or should have known of a hazardous condition and failed to remedy it or warn visitors. Comparative negligence layers a second inquiry: did the plaintiff exercise reasonable care for their own safety?
A grocery-store slip-and-fall in Dayton illustrates the dynamic. A customer slips on a wet floor near the produce section. The store's insurer argues the customer ignored a yellow caution cone placed three feet from the spill, assigning 60% fault to the plaintiff. Discovery reveals the cone was added to the scene after the fall (timestamped security footage proves it), and the floor had been wet for 40 minutes with no warning. The jury assigns 90% fault to the store, 10% to the plaintiff for wearing smooth-soled sandals on a rainy day. The plaintiff recovers 90% of damages.
Common defense arguments in premises cases:
- "Open and obvious" doctrine: Ohio law traditionally barred recovery when a hazard was open and obvious to a reasonable person, though recent Supreme Court of Ohio decisions have softened this rule.
- Plaintiff was distracted by a phone or conversation
- Plaintiff ignored posted warnings
- Plaintiff wore inappropriate footwear
- Plaintiff was in an area marked "Employees Only"
Each argument aims to nudge fault over 51%. Effective plaintiff advocacy documents the hazard's subtlety (a clear liquid on white tile, black ice on black asphalt) and the defendant's superior knowledge of the danger.
Wrongful Death and Comparative Negligence
Ohio Revised Code 2125.02 allows the personal representative of a decedent's estate to bring a Wrongful Death action when another party's negligence caused the death. Comparative fault applies even when the injured party cannot testify. Insurers argue the decedent's actions—crossing against a signal, riding a motorcycle at high speed, failing to seek timely medical care—contributed to the fatal outcome.
These cases demand careful reconstruction. In a 2021 Cuyahoga County wrongful-death suit arising from a Cleveland intersection crash, the defendant's insurer claimed the decedent (a motorcyclist) was traveling 70 mph in a 35-mph zone, assigning 65% fault. Plaintiff's counsel retained an accident reconstructionist who used motorcycle ECU data, intersection video, and skid-mark analysis to show the decedent's speed was 42 mph—above the limit but not recklessly so. The jury assigned 25% fault to the decedent, 75% to the defendant (who had turned left across the motorcycle's path without yielding under ORC 4511.42). The estate recovered 75% of a $1.2 million verdict.
Defendants cannot depose the deceased, but they can question surviving passengers, review social-media posts, obtain phone records, and hire biomechanics experts who opine on speed and conduct. Building the decedent's case requires witness interviews, records from employers or medical providers, and experts who can interpret physical evidence.
Comparative Negligence at the Settlement Table
Most Ohio injury cases settle before trial. Comparative negligence doesn't vanish in that context—it drives negotiation ranges. An experienced adjuster evaluates liability on a fault spectrum:
| Estimated Plaintiff Fault | Likely Adjuster Strategy | Typical Settlement Range (as % of provable damages) |
|---|---|---|
| 0-10% | Minimal liability dispute; focus on damages valuation | 75-95% |
| 11-25% | Moderate reduction; some pressure to settle quickly | 60-80% |
| 26-40% | Significant discount; carrier may lowball and wait | 40-65% |
| 41-50% | Aggressive defense; high risk of zero recovery at trial | 20-50% |
| 51%+ (defendant's view) | Deny liability entirely; offer nuisance value or zero | 0-15% |
These ranges aren't formulas; they're negotiating positions. A plaintiff with strong evidence and a credible story may secure 90% of damages even when carrying 15% fault. Conversely, a plaintiff with sparse documentation might accept 40% on a case where true fault is only 10%.
Demand letters that pre-emptively address comparative negligence fare better than those that ignore it. Acknowledging minor plaintiff missteps ("My client was traveling 5 mph over the limit") while emphasizing the defendant's greater culpability ("Your insured ran a red light at 50 mph in a school zone") builds credibility and frames the negotiation.
Comparative Fault and Subrogation
When your health insurer or auto Med Pay carrier pays your medical bills, they acquire a subrogation lien—a right to reimbursement from your injury settlement or verdict. Ohio law requires that subrogation liens be reduced proportionally by your percentage of fault.
Suppose you're 20% at fault in a collision. Your health insurer paid $30,000 in medical bills and holds a lien. You settle for $100,000. The insurer's lien reduces to $24,000 (80% of $30,000), not the full $30,000. This rule, rooted in equitable principles and codified in Ohio case law, prevents subrogation carriers from recovering more than their fair share.
Negotiating these liens requires understanding both the comparative-fault reduction and federal rules like the Medicare Secondary Payer Act, which governs Medicare and Medicaid liens. An attorney experienced in lien resolution can often negotiate further reductions based on procurement costs (the contingency fee and litigation expenses you paid to secure the settlement).
Ohio Cities and Localized Fault Considerations
Urban jurisdictions see recurring comparative-fault patterns:
- Columbus: High pedestrian traffic downtown and near Ohio State's campus creates frequent crosswalk disputes. Plaintiffs often face arguments that they "darted" into traffic, while defendants' failure to yield under ORC 4511.46 forms the core liability claim.
- Cleveland: Lake-effect snow and road-salt delays make winter-weather driving a common fault factor. Juries expect drivers to adjust speed under ORC 4511.21, but "too fast for conditions" arguments cut both ways.
- Cincinnati: Hilly terrain and older street infrastructure contribute to visibility disputes. Defendants argue plaintiffs "should have seen" stop signs obscured by tree branches; plaintiffs counter that the city failed in its maintenance duties.
- Akron: Manufacturing and industrial trucking create frequent Truck Accident cases on State Route 8 and I-76. Fault often spreads among drivers, carriers, and maintenance contractors.
- Toledo: Proximity to Michigan and high cross-border traffic means some cases involve choice-of-law questions when crashes occur near the state line, though Michigan's modified comparative-negligence threshold is also 51%.
- Dayton: Wright-Patterson Air Force Base traffic and heavy commuter corridors (I-75, I-70) yield multi-vehicle pileups where fault splits among many parties.
- Youngstown: Aging infrastructure and deferred road maintenance create pothole-related claims. Plaintiffs must prove the municipality had notice of the defect under governmental-immunity statutes.
Common Misconceptions About the 51% Rule
Myth 1: "If I'm any percent at fault, I lose everything."
Reality: You can be 50% at fault and still recover half of your damages. Only at 51% and above does recovery drop to zero.
Myth 2: "The police report determines my fault percentage."
Reality: Police reports are evidence, not verdicts. Courts frequently depart from officer conclusions when additional evidence—dashcam video, expert testimony, witness interviews—tells a different story.
Myth 3: "If I apologized at the scene, I admitted fault."
Reality: Ohio Evidence Rule 409 makes offers of compromise and certain statements made during settlement negotiations inadmissible. A spontaneous "I'm sorry" at the scene is admissible but not dispositive; juries understand human empathy doesn't equal legal liability.
Myth 4: "Comparative fault only matters at trial."
Reality: Insurers evaluate fault percentages from day one. A well-documented demand package that pre-emptively counters inflated fault claims often secures better settlements without litigation.
Myth 5: "The defendant's insurance company decides my fault percentage."
Reality: If you reject the insurer's evaluation and file suit, a jury of your peers decides fault. Adjusters have no final say outside settlement.
Protecting Your Claim from Inflated Fault Allegations
Actionable steps after any accident:
- Preserve evidence immediately: Take photos of vehicle positions, skid marks, traffic signals, weather conditions, road defects, and visible injuries before anything moves.
- Obtain witness contact information: Bystanders disappear quickly. Names, phone numbers, and brief statements matter.
- Request police body-cam and dashcam footage: Many agencies auto-delete after 30-60 days. File public-records requests under Ohio Revised Code Chapter 149 promptly.
- Secure your own vehicle's data: Event data recorders (EDRs) in modern vehicles capture speed, braking, and steering inputs in the seconds before impact. Insurers download this data; you should too.
- Avoid recorded statements to the other party's insurer: You have no duty to provide one, and adjusters often use these statements to extract admissions of fault.
- Document all medical treatment: Gaps in care become "evidence" that injuries weren't serious. Consistent treatment logs counter claims you caused your own harm by delaying care.
- Consult an attorney before accepting any settlement: Releases are final. Once you sign, you cannot revisit the fault calculation.
Key Takeaways
- Ohio's 51% comparative-negligence rule allows you to recover reduced damages if you're 50% or less at fault; at 51% or higher, you recover nothing.
- Fault percentages are jury questions based on evidence—police reports influence but don't dictate the outcome.
- Insurers routinely inflate your fault percentage during settlement negotiations to reduce payouts or deny claims entirely.
- Comparative fault applies across all injury contexts: car crashes, truck collisions, motorcycle accidents, slip and fall incidents, and wrongful death cases.
- Multiple defendants may each carry separate fault percentages; as long as yours stays at or below 50%, you recover a proportionally reduced award.
- Seat-belt and helmet non-use affect damage mitigation, not liability percentages, under Ohio law.
- Strong evidence collection at the accident scene protects you from inflated fault allegations later.

Frequently asked questions
What happens if I'm 50% at fault for my Ohio accident?
Under Ohio Revised Code 2315.33, you can still recover damages if you're exactly 50% at fault. Your award will be reduced by your percentage of fault, so if a jury awards $100,000 and finds you 50% responsible, you collect $50,000. This differs from some states with a 50% bar rule where you'd recover nothing. The critical threshold in Ohio is 51%—once you cross that line, recovery drops to zero. Insurers know this cliff exists and often argue you're 51% or more at fault during settlement talks to avoid paying anything. Having strong evidence that keeps your fault at 50% or below is essential for preserving your right to compensation.
How do Ohio juries determine fault percentages in car accidents?
Juries evaluate each party's conduct against the duty of reasonable care and assign specific numerical percentages totaling 100%. They consider traffic law violations (speeding, failure to yield, running red lights), witness testimony, police reports, dashcam footage, accident reconstruction, and expert opinions on causation. For example, if Driver A was texting and drifted into oncoming traffic while Driver B was speeding 10 mph over the limit, a jury might assign 80% fault to Driver A and 20% to Driver B. The jury receives special verdict forms requiring them to write exact percentages for each party. Police reports influence but don't control these decisions—juries frequently depart from officer conclusions when additional evidence contradicts the initial report.
Can I still sue if the police report says I caused the accident?
Absolutely. Police reports are evidence presented to the jury, not final determinations of liability. Officers often arrive after a crash, rely on brief driver statements, and form quick conclusions without access to dashcam footage, vehicle data recorders, or detailed witness interviews. In many cases, subsequent investigation reveals facts the officer never knew. You have the right to present contradicting evidence—video footage, expert accident reconstruction, biomechanics testimony, cell phone records disproving distraction—that tells a different story. Ohio courts routinely see juries assign fault percentages that differ dramatically from police report conclusions. An unfavorable police report makes your case more challenging but far from impossible, especially with experienced legal representation gathering evidence the officer never saw.
Does Ohio's comparative negligence rule apply to truck accidents with multiple defendants?
Yes, and the math becomes more complex when multiple parties share fault. In a commercial trucking case, the jury might assign separate fault percentages to the truck driver (40%), the trucking company for negligent hiring (20%), a third-party vehicle (15%), and you as the plaintiff (25%). As long as your percentage stays at 50% or below, you recover damages reduced by your share. In this example, if total damages equal $500,000, you'd collect $375,000 (75% of the award). The various defendants then pay according to Ohio's modified joint-and-several liability rules. Truck accident cases often involve many parties—drivers, carriers, maintenance contractors, cargo loaders, manufacturers—each potentially bearing a slice of fault. This complexity is precisely why these cases demand attorneys experienced in multi-defendant litigation.
Can my damages be reduced for not wearing a seat belt in Ohio?
Ohio Revised Code 4513.263 prohibits using seat-belt non-use as evidence of comparative negligence, meaning it won't push you toward the 51% threshold. However, defendants can argue failure to wear a seat belt increased the severity of your injuries—a mitigation argument rather than a fault argument. A biomechanics expert might testify that specific injuries (like rib fractures or internal organ damage) would have been prevented or reduced by belt use, while other injuries (like whiplash) would have occurred regardless. The jury then reduces your award only for the preventable harm. For example, if your total damages are $100,000 but $30,000 relates to injuries a seat belt would have prevented, you'd recover $70,000. The same principle applies to motorcycle helmet use, though Ohio has no universal helmet law for adults.
What if the insurance company says I'm 60% at fault—do I have any options?
The insurance adjuster's opinion is just that—an opinion with no legal binding force. Fault percentages in disputed cases are jury questions, not insurer decisions. If you reject the adjuster's evaluation and file a lawsuit, twelve Ohio residents will hear all the evidence and decide fault independently. Insurers routinely overstate plaintiff fault during pre-suit negotiations to pressure low settlements. An adjuster might cite a vague police-report notation or cherry-pick one unfavorable fact while ignoring ten facts supporting your version. This is where legal representation matters. An attorney marshals evidence—dashcam video, expert reconstruction, witness depositions, FMCSA violations in truck cases—that often reveals your actual fault is far lower than the adjuster claimed. Many cases the adjuster pegged at 60% plaintiff fault settle for amounts reflecting 20-30% plaintiff fault once discovery is complete.
How does comparative fault work in Ohio slip and fall cases?
Property owners owe visitors a duty to maintain reasonably safe premises and warn of non-obvious hazards. When you're injured in a slip and fall, the owner's insurer will argue you failed to watch where you were walking, ignored warning signs, wore inappropriate shoes, or were in a restricted area—all to push your fault over 51%. Ohio law historically used the 'open and obvious' doctrine to bar recovery when hazards were plainly visible, though recent Supreme Court of Ohio decisions have softened this defense. Juries now weigh factors like lighting conditions, whether the hazard contrasted with its surroundings, how long the hazard existed, and whether the owner knew or should have known about it. A wet grocery-store floor might seem open and obvious in daylight but not in dim lighting with clear liquid on white tile. Even if the jury finds you 30% at fault for distraction, you recover 70% of your damages as long as you stay below the 51% bar.
Can I recover compensation in a wrongful death case if my loved one was partially at fault?
Yes, Ohio Revised Code 2125.02 allows recovery in wrongful death actions even when the decedent bore some responsibility for the incident, provided their fault doesn't exceed 50%. Insurers often argue the deceased was speeding, failed to wear a helmet, ignored traffic signals, or delayed medical care, hoping to assign 51%+ fault and eliminate liability. These cases are challenging because the person who could best explain their actions is no longer alive. The estate's attorney must reconstruct events using physical evidence—vehicle data recorders, intersection cameras, witness statements, phone records, medical examiner reports—and expert testimony from accident reconstructionists and biomechanics specialists. In a 2021 Cleveland case, a defendant claimed a deceased motorcyclist was traveling 70 mph in a 35-mph zone (which would have suggested high fault). Vehicle data proved 42 mph, and the jury assigned only 25% fault to the decedent, allowing the estate to recover 75% of a $1.2 million verdict.
What's the difference between Ohio's 51% rule and other states' comparative negligence laws?
Comparative negligence rules vary widely. Pure comparative negligence states (California, New York, Florida) let you recover even if you're 99% at fault—you'd just collect 1% of damages. Modified comparative negligence states set a threshold: Ohio and most states use a 51% bar (you lose everything at 51% or higher), while a few like Wisconsin use a 50% bar (you lose everything at exactly 50%). A handful of states including Alabama and North Carolina still follow contributory negligence, where 1% fault eliminates recovery entirely. Ohio's 51% rule represents middle ground—more forgiving than contributory-negligence states but harsher than pure comparative-negligence jurisdictions. This matters for interstate crashes near Ohio's borders. Choice-of-law rules determine which state's negligence standard applies, potentially affecting whether you recover anything at all in a borderline-fault scenario.
How do I prove the other driver was more at fault than me in Ohio?
Proving superior fault requires layered evidence. Start with the police report, though remember it's not dispositive. Gather traffic-camera or business-surveillance footage showing the collision. Download your vehicle's event data recorder (EDR) to document your speed, braking, and steering. Obtain phone records for both drivers to prove or disprove distraction. Interview witnesses immediately while memories are fresh. Hire an accident reconstructionist who can analyze skid marks, vehicle damage, and roadway evidence to calculate speeds and sight lines. In truck cases, subpoena the carrier's hours-of-service logs, maintenance records, and driver qualification files to show FMCSA violations. Identify specific traffic law violations—running a red light (ORC 4511.13), failure to yield right-of-way (ORC 4511.42), speeding (ORC 4511.21)—that establish negligence per se. The more objective evidence you compile early, the harder it becomes for insurers to inflate your fault percentage.
