- An 18-wheeler crash is governed by federal trucking rules that never apply to an ordinary driver: commercial licensing, hours-of-service limits, electronic logs and post-crash drug and alcohol testing.
- The claim usually involves more defendants and more evidence: the driver, the motor carrier, and sometimes the trailer owner, the loader or a repair shop, plus company records that can be discarded after a few months.
- Coverage is far larger: interstate for-hire freight carriers must carry at least $750,000 in liability coverage, while a Texas car owner’s minimum is $30,000 per injured person. Texas also has special trial rules for commercial vehicle cases.
What makes 18-wheeler accident claims different from regular car accident cases? The short answer is that a truck crash is a claim against a regulated business, not just against another driver.
That changes who can be held responsible, what evidence exists, how much insurance stands behind the truck, and, in Texas, how the case is tried. The basic negligence questions stay the same, but almost everything around them gets bigger.
This guide walks through the five main differences, explains the Texas rules that apply only to commercial vehicle cases, and ends with what to look for in a lawyer for this kind of claim.
Five Differences at a Glance
A car crash claim is usually one driver, one insurer and one police report. An 18-wheeler claim adds a federal rulebook, a company, and a paper trail that the company controls.
The chart sets the two kinds of claims side by side. Each difference is explained below.
| Issue | Typical car accident claim | Typical 18-wheeler claim |
|---|---|---|
| Rules of the road | State traffic laws | State traffic laws plus federal motor carrier safety rules |
| Who can be liable | Usually the other driver | Driver, motor carrier, and possibly trailer owner, loader, repair shop or manufacturer |
| Key evidence | Police report, photos, witnesses | All of that, plus electronic logs, driver files, maintenance records and test results |
| Insurance | Texas minimum $30,000 per person | At least $750,000 for interstate for-hire general freight |
| Texas trial rules | Standard procedure | Chapter 72 bifurcation and evidence limits on request |
1. Federal Safety Rules Govern the Truck and the Driver
A car driver answers to state traffic law. A commercial truck driver also answers to the Federal Motor Carrier Safety Regulations, which cover licensing, medical fitness, driving hours, vehicle maintenance and drug and alcohol testing.
The hours rules are the best known. Under 49 CFR 395.3, a property-carrying driver may drive a total of 11 hours after 10 consecutive hours off duty, and may not drive once 14 hours have passed since coming on duty.
The same section requires a 30-minute break after 8 hours of driving, and caps on-duty time at 60 hours in 7 days or 70 hours in 8 days, depending on the carrier’s schedule.
Most carriers must track those hours with an electronic logging device. 49 CFR 395.8 requires motor carriers to install ELDs and have their drivers use them, with limited exceptions.
After certain crashes, the carrier must also test the driver. 49 CFR 382.303 requires alcohol and drug testing after any crash involving a death, and after injury or tow-away crashes when the driver receives a citation.
Why it matters: a broken safety rule can be strong evidence of negligence.
A driver who was over the hours limit, or a carrier that skipped required testing, gives an injured person a line of proof that does not exist in an ordinary car crash.
2. More Parties Can Share the Blame
In a car crash, the at-fault driver and that driver’s insurer are usually the whole case. In an 18-wheeler case, the driver is often an employee, and the company that employs the driver is usually responsible for the driver’s on-the-job negligence.
Other parties can also be involved, depending on the facts:
- The motor carrier, for its own conduct in hiring, training, supervising or scheduling the driver.
- The owner or lessor of the tractor or trailer, when it is a different company.
- The shipper or loader, if cargo was overloaded or poorly secured.
- A maintenance contractor, if brakes, tires or lights were not properly repaired.
- A manufacturer, if a defective part contributed to the crash.
More defendants usually means more insurers, more lawyers on the other side and more disputes about who pays what share. In Texas, fault is divided under the state’s proportionate responsibility statute, and an injured person cannot recover if found more than 50 percent responsible.
3. The Evidence Lives in Company Records, and Some of It Expires
The most important evidence in a truck case is often held by the carrier. Federal rules require it to keep records, but only for set periods. Once those periods pass, the records can lawfully be discarded unless someone asks the company to preserve them.
| Record | Federal rule | Minimum retention |
|---|---|---|
| Hours-of-service records and supporting documents | 49 CFR 395.8(k) | 6 months |
| Inspection, repair and maintenance records | 49 CFR 396.3(c) | 1 year, and 6 months after the vehicle leaves the carrier’s control |
| Driver qualification file | 49 CFR 391.51 | While employed, plus 3 years |
| Accident register | 49 CFR 390.15(b) | 3 years after each accident |
Six months can pass quickly while someone is in treatment. That is why lawyers in truck cases often send the carrier a preservation letter early, asking it to keep the logs, dashcam footage, engine data, dispatch messages and driver file.
Police reports and photos still matter, but in a truck case they are usually the starting point, not the whole file.
4. Much Larger Insurance Policies
Texas sets the minimum liability coverage for a private car at $30,000 for one injured person, $60,000 per crash for injuries and $25,000 for property damage, under Transportation Code section 601.072.
Interstate trucking runs on a different scale. Under 49 CFR 387.9, a for-hire carrier hauling general freight across state lines in a vehicle rated at 10,001 pounds or more must carry at least $750,000 in public liability coverage.
The minimum rises to $1 million for oil and certain hazardous materials, and to $5 million for some hazardous materials hauled in bulk. These are floors: many carriers buy more, and intrastate carriers can be subject to different state rules.
Larger coverage means a serious injury is less likely to outrun the available insurance. It also means more money is at stake, so expect the carrier and its insurer to investigate and defend the claim closely.
5. Heavier Vehicles, Usually Worse Injuries
On the Interstate System, federal law generally allows a truck’s overall gross weight up to 80,000 pounds under 23 U.S.C. 127. A passenger car is a small fraction of that.
The weight gap is why truck crashes so often involve fractures, brain and spinal injuries or death. Bigger injuries mean longer treatment, higher future costs and lost earning capacity, and each of those has to be documented and proven with medical and economic evidence.
How Texas Law Treats 18-Wheeler Cases Differently
Texas adds its own layer. Since 2021, Chapter 72, Subchapter B of the Civil Practice and Remedies Code sets special rules for injury and death claims arising from commercial motor vehicle collisions.
Two-phase trials. If a defendant asks in time, the court must split the trial. Under section 72.052, the jury first decides liability and compensatory damages, then decides any exemplary damages in a second phase.
Limits on regulation evidence. Section 72.053 lets evidence of a broken safety rule into the first phase only if it tends to prove the violation was a proximate cause of the injury and the rule specifically governs the defendant.
The employer stipulation. Under section 72.054, if the company admits in time that the driver was its employee acting within the scope of employment, its liability for the driver’s ordinary negligence rests on that relationship.
In that situation, claims such as negligent entrustment are limited in the first phase to a list of facts the statute names, such as licensing, disqualification, hours-of-service violations, out-of-service orders and certain testing failures. Claims like negligent maintenance are not restricted the same way.
Photos and video. Section 72.055 says a court may not require expert testimony to admit a properly authenticated photo or video of a vehicle in the collision, except as needed to authenticate it.
Some things do not change. The deadline to sue for personal injury or wrongful death is generally two years under section 16.003, the same as for a car crash, though exceptions can apply.
How these rules play out depends on the facts, so treat this section as an overview, not a prediction for any one case.
What to Do After a Crash With an 18-Wheeler
- Get medical care and keep every record and bill.
- Write down the truck’s company name, USDOT number and trailer number if you can see them.
- Take photos of the vehicles, the road and any cargo, and get witness names.
- Do not give a recorded statement to the carrier’s insurer before you get advice.
- Talk to a lawyer early, so a preservation letter goes out before short retention periods run.

Questions to Ask a Truck Accident Lawyer
- How soon will you send a preservation letter, and to whom?
- How do you obtain ELD data, dashcam footage and the driver qualification file?
- Which parties besides the driver and the carrier could be responsible here?
- How would a Chapter 72 stipulation or bifurcation affect my case?
Conclusion
An 18-wheeler claim differs from a car accident case because the truck is part of a regulated business. Federal rules shape the evidence, several companies may share responsibility, and the insurance is usually much larger.
Texas adds its own trial rules for commercial vehicle cases, while the basic two-year deadline stays the same. Acting early protects records that may only be kept for months.
