The short answer: very few. Most personal injury claims — including those arising from motor vehicle accidents — are resolved through settlement negotiations, never reaching a courtroom. Estimates from legal researchers and industry analysts consistently suggest that roughly 95% or more of personal injury cases settle before trial. But that number doesn't tell the full story of why, or what shapes whether any individual case ends up in the exceptions.
There's an important distinction to understand at the start. A claim and a lawsuit are not the same thing.
When someone files a claim after a crash, they're typically working through an insurance process — either their own insurer (a first-party claim) or the at-fault driver's insurer (a third-party claim). At this stage, no court is involved. An adjuster investigates, reviews medical records, police reports, and property damage, and eventually makes a settlement offer.
A lawsuit only enters the picture when that insurance process breaks down — meaning negotiations stall, an offer is disputed, liability is contested, or a coverage limit won't cover the damages claimed. Even after a lawsuit is filed, the overwhelming majority of cases still settle before a judge or jury ever weighs in.
Insurance companies and claimants both have incentives to avoid trial:
These dynamics push the vast majority of cases toward negotiated resolution, even when liability is disputed.
Certain factors consistently increase the likelihood that a case will move through litigation rather than settle:
| Factor | How It Affects the Path |
|---|---|
| Disputed liability | When fault isn't clear, insurers may deny or lowball claims, prompting lawsuits |
| Severe or permanent injuries | High-value claims exceed policy limits, creating gaps that can't be resolved through the insurer alone |
| Coverage limits | When the at-fault driver's liability limits are insufficient, litigation may be the only path to full compensation |
| Bad faith conduct | If an insurer is accused of unreasonably denying or delaying a valid claim, litigation may follow |
| Multiple parties | Crashes involving commercial vehicles, government entities, or several drivers complicate liability and often require court involvement |
| Unresolved medical treatment | Cases where the full extent of injury isn't yet known are harder to settle; some claimants can't accept a number until treatment is complete |
Attorney involvement also shapes this path. Personal injury attorneys working on contingency fee arrangements (typically a percentage of the final recovery, which varies by state and case stage) have both the tools and the incentive to pursue litigation when a settlement doesn't reflect the documented damages.
This is where many people misunderstand the process. Filing a lawsuit is a legal step that opens the door to discovery — the formal exchange of evidence, depositions, and documentation between both sides. Most cases that reach this stage still settle during discovery or before trial begins.
The phases between filing and trial include:
Each of these phases creates another opportunity to settle. Statistically, cases that survive to the courthouse steps frequently resolve the morning of — or even during — trial.
Where a case occurs shapes how it's handled, including whether litigation is even necessary.
In no-fault states, injured drivers first turn to their own Personal Injury Protection (PIP) coverage regardless of who caused the crash. In many of these states, there's a tort threshold — a minimum injury severity that must be met before someone can step outside the no-fault system and sue the at-fault driver. States with strict thresholds filter out many claims before they ever approach a courtroom.
In at-fault states, injured parties typically go directly against the at-fault driver's liability coverage. If that driver is uninsured or underinsured, the claimant may turn to their own UM/UIM coverage — which can also become a point of dispute that ends in litigation.
Comparative fault rules add another layer. In states using pure comparative negligence, a claimant can recover even if they were mostly at fault — though their recovery is reduced. In states using modified comparative negligence, recovery may be barred above a certain fault percentage. In the small number of states that still apply contributory negligence, any share of fault can bar recovery entirely. These rules directly affect settlement leverage and whether a case is worth pursuing to trial.
Understanding that 95% of cases settle is useful context — but it doesn't tell you which side of that number your case falls on. That depends on the specific facts of the crash, the injuries involved, the coverage available, the state where the accident occurred, and how clearly liability can be established.
The same accident that settles quietly in one state might become a prolonged legal dispute in another, simply because of how fault rules, coverage requirements, or tort thresholds differ.
