18-Wheeler Accident Settlement Calculator

Settlement value in a commercial truck case rests on two pillars: liability and damages. Strong evidence of the trucking company's negligence—not just driver error—drives settlement significantly higher.

Liability factors:

• Driver hours-of-service violations (logged beyond 11 hours, falsified ELD entries)
• Maintenance records showing deferred repairs or known mechanical failures
• Driver qualification file gaps (expired DOT medical certificates, prior violations)
• Motor carrier safety records—check the [FMCSA motor carrier safety database](https://safetydata.fmcsa.dot.gov/) for CSA (Compliance Safety Accountability) scores. A high unsafe-driving or HOS score suggests systemic negligence
• Post-crash drug and alcohol test results
• Dispatch communications showing time pressure, mechanical concerns, or unsafe directives
• Third-party liability (broker, shipper, loader, trailer owner)

Damages factors:

• Medical expenses (surgery, hospitalization, ongoing treatment, adaptive equipment)
• Lost wages (past and future)
• Permanent disability or scarring
• Life expectancy and long-term care costs
• Pain and suffering
• Punitive damages eligibility (when the carrier's conduct was willful or reckless)

The strongest cases combine clear evidence of motor carrier violations with significant, documented injury. A carrier with a clean safety record defending itself is a much weaker defense than a carrier with intervention-level CSA scores.

Minor injury (contusion, minor fracture, soft tissue strain):

$20,000 – $75,000

Healing occurs within 6–12 months. No ongoing treatment needed. Medical bills run $5,000–$25,000. Wage loss is temporary. Settlement reflects actual damages plus modest pain and suffering.

Moderate injury (broken bones, herniated disc, significant laceration):

$75,000 – $300,000

Requires surgery or extended physical therapy. Possible permanent limitation (chronic pain, reduced range of motion). Medical costs reach $30,000–$100,000. The plaintiff may eventually return to work but not at baseline. Future medical treatment is likely.

Severe injury (spinal cord damage, traumatic brain injury, amputation, solid organ damage):

$300,000 – $2,000,000

Permanent disability. Ongoing medical care, adaptive equipment, home modifications are necessary. The plaintiff will never work at pre-injury capacity. Long-term care and future medical costs dominate the settlement calculation.

Catastrophic injury (permanent paralysis, wrongful death, multiple amputations, severe TBI requiring full-time attendant care):

$1,500,000 – $5,000,000+

Lifetime care costs and loss of earning potential are staggering. Punitive damages frequently apply. Insurance policy limits are often exhausted, and courts may issue judgments against the trucking company's assets.

Your settlement ceiling depends partly on where you litigate.

Comparative negligence rules vary by state. Pure comparative negligence states (California, New York, Texas) allow recovery even if the plaintiff is 90% at fault, reduced by that percentage. Modified comparative negligence states bar recovery if the plaintiff is 50% or more at fault. A few states follow strict contributory negligence (any plaintiff fault bars recovery). A defense attorney will argue the other driver caused the crash; your state's rule determines how much that matters.

Non-economic damages caps exist in a handful of states. Most personal injury cases are uncapped, but a few states limit pain-and-suffering awards. Check your state's specific rules.

Jury attitudes differ by region. Rural areas near trucking hubs may have juries sympathetic to industry concerns. Urban areas with high commercial litigation experience award higher settlements. Your attorney's local knowledge matters here.

Insurance coverage is the hard ceiling. Most large carriers carry $1,000,000+ in liability insurance. Smaller carriers or independent operators may carry only the federally mandated minimum ($750,000). If policy limits are exhausted, settlement caps there. A judgment against the company's personal assets is available but often uncollectible.

Consult an attorney licensed in your state to understand how these factors apply to your specific case.

This calculator is a starting point. Real settlements diverge from the estimated range based on evidence quality, credibility, and circumstances.

Evidence is everything. Video footage of the truck crossing the center line, ELD data showing the driver exceeded HOS limits, and records from [NHTSA's crash database](https://www.nhtsa.gov/) all dramatically strengthen your claim. A case with only police reports and conflicting witness statements will settle much lower.

Comparative fault cuts both ways. If the plaintiff also violated traffic law (speeding, improper lane change), the defense uses it to argue shared liability. Fault is apportioned, and settlement drops proportionally.

Witness credibility. An independent witness who saw the crash unfold is worth substantial settlement leverage. Dash-cam footage from other vehicles is similarly powerful. Without corroboration, cases settle lower.

Medical expert presentation. A credible medical team explaining complex injuries in plain terms increases settlement value. Conversely, weak medical support reduces it.

Defendant solvency. If the trucking company is judgment-proof (minimal insurance, no corporate assets), insurers know a jury award may go uncollected. They lowball early offers. A strong case against an underinsured defendant may settle lower than expected.

Your attorney will evaluate the actual evidence, assess jury pool attitudes in your county, and negotiate with the motor carrier's insurance counsel. Settlement ranges shift based on these real-world factors.
