Truck accident cases are not just big car accident cases. They can involve different federal safety rules, a different kind of insurance and specialized evidence which the trucking company may only have to keep for a limited time. These can change how the case is investigated, pursued in court and the compensation available to people injured in a commercial vehicle crash.
Many people think a truck crash claim works like a car crash claim, only with bigger numbers. While the numbers are usually larger, there‘s a lot more that makes these cases different.
The differences discussed below are specific to truck crash cases. They affect what your lawyer needs to do from the get-go. They are also why lawyers with only a general injury practice background can be a disadvantage from the start in a trucking case.
1. Federal Safety Rules Apply in Addition to State Traffic Laws
Every driver has to follow state traffic law. Most interstate trucking companies and their drivers also have to follow the Federal Motor Carrier Safety Regulations (FMCSRs), found at 49 C.F.R. Parts 350 through 399.
These rules cover things which state traffic laws never address. They set truck driver qualifications, how the company must check a driver’s history before hiring, how long a driver can stay behind the wheel, when the truck must be inspected, how drug and alcohol testing works and lots more.
This is important because violation of these rules can be evidence of negligence. A driver who ran past the 11-hour driving limit in FMCSR §395.3 may have broken a federal safety rule, even if they did not break a traffic law. In a car case, there is usually nothing comparable to point to.
Most law schools teach none of this. Before you hire a lawyer to represent you in a truck accident case, ask if they have actual training in the FMCSRs. Lawrence Flick has completed U.S. Department of Transportation training on the FMCSRs and truck crash investigation.
2. Key Evidence Can Disappear Fast
Some of the most important evidence in an 18 wheeler case can come directly from the truck that hit you. Modern big commercial trucks are often equipped with an engine control module (ECM). The ECM can contain key data like how fast the truck was going in the moments before the crash, the speed at which the truck hit you and when the driver braked. This data can be lost if prompt steps are not taken to preserve it. Physical damage to the truck can tell an important story about how the crash occurred. It’s important that the physical damage be documented before the truck is repaired.
Trucking company documents can be another key evidence source. Ordinarily, the FMCSRs only require trucking companies to keep these records for a limited period of time. Examples of trucking company records which can contain key evidence, how they can be important and how long the company is required to keep them are:
| Record | What it can show | Retention Period | FMSCR |
|---|---|---|---|
| Driver logs and supporting documents | Driving and on-duty hours, rest taken, whether limits were broken | 6 months from receipt | FMCSR §395.8(k)(1) |
| Driver vehicle inspection reports | Mechanical defects to the truck | 3 months | FMCSR §396.11(a)(4) |
| Roadside inspection reports | Violations enforcement officers already found | 12 months | FMCSR §396.9(d)(3)(ii) |
| Maintenance and repair files | Brake, tire, and steering work, or the lack of it | 1 year, plus 6 months after the truck leaves the carrier | FMCSR §396.3(c) |
| Driver qualification file | Hiring, training, prior driving record | Employment plus 3 years | FMCSR §391.51(c) |
| Accident register | Other crashes the same company has had | 3 years from the crash date | FMCSR §390.15(b) |
Read that first row again. Six months. A driver’s logs can be gone before many people have finished treatment, and long before a lawsuit is filed.
The fix can be a preservation letter, sometimes called a “spoliation letter”. Sent soon after the crash and hopefully before evidence is lost, it tells the trucking company to preserve specific evidence. The letter needs to list the specific records and evidence to be preserved. A vague demand to “preserve all evidence” gives a carrier room to argue about what was covered.
These are some of the reasons that honest advice after a truck crash is to call an experienced 18 wheeler accident lawyer quickly. Not because of pressure tactics. But because the clock on preserving this evidence is already ticking.
3. Trucking Insurance Can Include a Federal Backstop
Most car accident cases involve personal auto insurance policies and liability coverage which often range from $25,000 to $250,000.
Federally authorized trucking companies hauling ordinary freight in vehicles weighing 10,001 pounds or more must carry at least $750,000 in financial responsibility under FMCSR § 387.9. Carriers hauling certain hazardous cargo must have $1 million. Some hazardous materials require $5 million. Some trucking companies have additional excess or umbrella insurance above the primary policy.
Most carriers meet that obligation with a liability policy which includes a special MCS-90 endorsement required by FMCSR §387.15. Understanding this endorsement is important. It can mean the difference between a paid claim and nothing.
Under the MCS-90, the insurer may have to pay a final judgment for public liability up to the federal minimum, even when the policy language excludes the claim. The insurer can then go back and seek repayment from the trucking company. The injured person gets paid first.
That $750,000 figure was set by the Motor Carrier Act of 1980 and has never been adjusted for inflation. In a serious injury case this coverage can be nowhere near enough. There have been repeated efforts to raise the minimum insurance requirement but as of 2026 it still remains at the level set in 1980.
4. More Than One Company Can Be Responsible
In a typical car case, the driver is the one responsible.
The truck which hit you can be part of a transportation system where several parties may be legally responsible for your crash. These can include:
- The driver, for how the truck was operated
- The trucking company for the driver’s actions. The company may also be liable for how they hired, trained and supervised the driver and maintained the truck
- The company that loaded or secured the cargo
- The shop or contractor responsible for maintenance
- The trailer or equipment owner, when that differs from the carrier
- In some situations, freight brokers or shippers
Each of these parties may carry separate insurance. Being able to hold them responsible may be what determines whether there is enough coverage to cover a catastrophic injury.
5. Trucks Crash in Ways Cars Do Not
Car cases cluster around a few patterns. Rear-end collisions and intersection crashes make up most of them.
Trucks crash those ways too. They also crash in ways that rarely have a passenger vehicle equivalent, including jackknifes, rollovers, trailer breakaways, runaway trucks on grades, falling or shifting cargo, and underride crashes where a car goes beneath the trailer.
Each of these has its own physics and its own likely causes. An underride case can turn on whether the truck was parked or moving, conspicuity and under ride guard design. A jackknife case can turn on speed, road conditions and equipment maintenance. While the investigations have common factors they are not Interchangeable.
6. The Cause Usually Runs Deeper Than One Bad Moment
Most car crashes come down to a driver’s choice at a specific moment. Followed too closely. Going too fast. Didn’t yield the right of way. Fault usually begins and ends with that person.
In truck crash cases the crash is often the last event in a series of bad choices made by the trucker and trucking company management.
A tired driver is one example. A fatigued trucker may have been past the federal driving limit. The question is why. Did management know drivers were falsifying their logs and let it continue? Did dispatch build a schedule that could not be run legally? Did the company hire a driver whose record already showed a problem?
The same logic applies to equipment failure. A brake failure can be a driver problem for a few seconds. Were proper pre-trip, post trip and annual inspections done? Were necessary repairs properly made? Did the company continue to operate the truck with defective brakes?
This is why, beyond evidence of what happened in the crash, trucking company records like driver qualification files, driver logs and maintenance records can be so important.
7. These Cases Often End Up in Federal Court
Trucking is a national industry. The driver and the company are frequently based in other states.
That opens the door to federal court. Under 28 U.S.C. 1332, a federal court can hear a case between citizens of different states when the amount in dispute is more than $75,000. Serious truck cases clear that number easily.
Here is the part that surprises people. Even if the case is filed in state court, the trucking company’s lawyers may be able to move it to federal court without your agreement. They generally have 30 days from being served to do it, with an outer limit of one year from filing in diversity cases.
Federal court runs on different rules, different deadlines, and different expectations. Plenty of capable injury lawyers avoid it. If your case can be removed, you want someone who litigates there by choice. Flick Truck Accident Law has been filing truck cases in federal court since 1999.
8. The Stakes Are Higher for Everyone
A loaded semi can weigh 80,000 pounds. A car weighs closer to 4,000 pounds. That gap is part of the reason these crashes produce lifelong or catastrophic injuries so often.
The pressure runs in every direction:
- You may be facing permanent injury, lost income, and lifetime medical costs
- The crash may affect the trucker’s ability to work as a truck driver in the future
- The motor carrier may face a judgment beyond its coverage
- The insurer may be looking at a claim in the millions
With so much on the line, people protect themselves. Stories can change. Records go missing. We have seen a trucker give a false account to law enforcement on video.
These are not reasons to assume bad faith from everyone. They are reasons to lock down the evidence early, before anyone has a reason to reconsider what they remember.

Frequently Asked Questions
How fast do I need to act to protect the trucking company’s records?
Faster than most people expect. Federal rules only require a carrier to keep driver logs and supporting documents for six months, and driver vehicle inspection reports for three months. A spoliation letter naming specific records should go out quickly, ideally within days of the crash.
What is an MCS-90 endorsement and how does it affect my claim?
It is a federally required endorsement attached to most interstate carriers’ liability policies under 49 C.F.R. 387.15. It obligates the insurer to pay a public liability judgment up to the federal minimum even if the policy would otherwise exclude the claim. The insurer can seek repayment from the trucking company afterward, but you get paid first.
Can the trucking company move my case to federal court without my agreement?
Often yes, if the requirements are met. When the parties are citizens of different states and more than $75,000 is in dispute, the defense can remove a case from state court to federal court under 28 U.S.C. 1332 and 1441. They generally have 30 days from service, with a one year outer limit in diversity cases.
Do I need a lawyer with specific truck training, or is any injury lawyer fine?
The Federal Motor Carrier Safety Regulations (FMCSRs), trucking technology and trucking company policy structures are all specialized. Most law schools teach none of it. Ask any lawyer you interview whether they have completed formal training in the FMCSRs before you sign anything.
Is an 18-wheeler case worth more than a car accident case?
Often, though not automatically. Two things tend to drive the difference. Injuries are usually more severe because of the weight gap, and commercial policies carry far higher limits than personal auto policies. Value still depends on the specific injuries, the evidence, and the coverage available.
