Truck Accident Checklist: What to Do After a Semi-Truck Crash in Missouri

Why This Matters

Critical Evidence Disappears Fast After a Truck Crash

A car accident and a truck accident are fundamentally different legal events. Semi-trucks are federally regulated under FMCSA rules. They carry sophisticated data recorders. And they're owned by companies with insurance teams and lawyers whose job starts the moment the crash happens.

The evidence that proves your case — and its full value — has a countdown timer on it. Here's what's at risk:

📱

Dashcam Footage

⏱ Loops in 24–72 hours

Most dashcams overwrite on a loop. Without a preservation demand, footage of the crash is gone within days.

💾

ELD / Hours of Service Data

⏱ Overwritten in 30 days

Electronic logging devices record every hour driven. If the driver was fatigued or violated hours-of-service rules, this data proves it.

⚙️

Black Box (ECM) Data

⏱ Overwritten after next event

Speed, braking, throttle position in the seconds before impact. Stored only until the next significant event overwrites it.

🛣️

Skid Marks & Road Debris

⏱ Days to weeks

Road crews clear debris fast. Skid marks fade with rain and traffic. Document everything at the scene.

👁️

Witness Memories

⏱ Fade within days

Details sharpen immediately after an event and blur fast. Get witness contact info at the scene.

📋

Driver Qualification File

⏱ Legally retained 3 years

Training records, drug test results, prior violations. A subpoena gets this — but only if you act before litigation deadlines.

At the Scene — If You're Physically Able

First Minutes

Call 911 immediately Critical

Even if injuries seem minor, always call police. A police report creates an official record of the crash, the truck driver's information, and initial conditions. Without it, the trucking company can dispute basic facts.
Move to safety, do not leave the scene

Get out of traffic lanes if you can do so safely. Stay until police arrive. Leaving the scene — even briefly — can complicate your claim.
Photograph everything before anything moves Critical

Truck position, your vehicle, skid marks, road conditions, traffic signs, damage, license plates, DOT number on the truck's door, trailer number. Take 360° photos from multiple distances. Video works too.
Get the truck's DOT number and company name Critical

The DOT number (on the door in large text) identifies the carrier. The carrier is who you're likely suing — not just the driver. Photograph it clearly.
Collect witness information

Name, phone number, and what they saw. Other drivers, pedestrians, anyone who stopped. Their independent account is worth more than yours to a jury.
Note the driver's condition and behavior

Was the driver using a phone? Did they seem fatigued, confused, or impaired? Were there open containers? Write these observations down while they're fresh — they support later investigation into hours-of-service violations or impairment.
Do NOT discuss fault at the scene

Never say "I'm sorry" or speculate about what happened. Stick to factual exchanges only: name, insurance, license. Anything more can be used against you later.

Medical Attention — Within Hours

Same Day

Get evaluated by a doctor today Critical

Adrenaline masks pain. Whiplash, internal bleeding, and TBIs often aren't felt for 24–48 hours. If you skip medical evaluation, the insurance company will argue your injuries aren't real or aren't related to the crash. Go to an ER or urgent care today.
Tell every provider exactly how the accident happened

Medical records that say "motor vehicle accident — semi-truck involved" create a documented chain of causation. Vague notes hurt your case.
Document all symptoms — even minor ones

Headaches, stiffness, difficulty sleeping, anxiety, concentration problems. Ask your doctor to note everything. Minor symptoms that worsen later are worth more when they're in the medical record from day one.
Follow every treatment recommendation

Skipping appointments or ignoring follow-up care is used by insurance adjusters to argue you weren't really hurt. Attend every appointment. Follow every referral.
Start a pain journal today

Daily log: pain level (1–10), what it stops you from doing, how it affects sleep and work. This journal becomes powerful evidence of non-economic damages — pain, suffering, loss of enjoyment of life.

Don't Navigate This Alone

Trucking companies have investigators, lawyers, and adjusters working immediately. You should too. Free consultation — no obligation.

Evidence & Insurance — Within 24 Hours

First 24 Hours

Notify your own insurance company

Report the accident — you're required to under most policies. But stick to facts. Do not admit fault. Do not estimate damages. Do not give a recorded statement to anyone without an attorney.
Do NOT give a recorded statement to the trucking company's insurer Critical

Their adjuster is trained to minimize your claim. You have no legal obligation to give a recorded statement to the other driver's insurance. Politely decline and say your attorney will be in touch. If you don't have one yet, call us now — we'll intervene immediately.
Save everything from the scene

Back up photos/videos to cloud storage immediately. Keep damaged clothing in a bag (don't wash it — bloodstains, tears, and glass show the force of impact). Save the police report number.
Preserve your vehicle before repair

Don't repair or junk your vehicle before an attorney or accident reconstructionist can inspect it. The vehicle tells the story of the impact. Insurers sometimes pressure victims to move quickly — resist.
Look for nearby surveillance cameras

Traffic cameras, business security cameras, and dashcams from other vehicles all capture accident footage. Many delete within 30–72 hours. Note any cameras near the crash site and tell your attorney immediately — they can send preservation letters.
Do not post about the accident on social media

Defense attorneys search social profiles. Even an innocent photo of you "looking fine" can be used to argue you're not injured. Set all profiles to private and don't post anything related to the crash.

Legal Action — Within 72 Hours

Days 1–3

Contact a truck accident attorney immediately Critical

Not a general personal injury attorney — one who handles FMCSA-regulated commercial vehicle cases. We can send a preservation letter to the trucking company, demand production of ELD data, dashcam footage, driver qualification files, maintenance logs, and drug test results before they're legally destroyed.
Do not accept any early settlement offer

Early offers are designed to close claims before you understand the full extent of your injuries. Once you sign a release, you cannot come back for more — even if you develop complications months later. Never sign anything without an attorney.
Request your police report

Missouri police reports are typically available within 7–10 days at your local law enforcement agency. Your attorney will use this for insurance negotiations and litigation.
Track all expenses from day one

Medical bills, prescriptions, transportation to appointments, missed work (get a wage verification letter from your employer), any out-of-pocket costs. Keep all receipts. These are your economic damages.

Ongoing — Throughout Your Recovery

Ongoing

Keep attending all medical appointments

Gaps in treatment are the #1 argument insurers use to reduce pain-and-suffering damages. Consistent care = documented ongoing injury.
Update your pain journal regularly

Date-stamped entries showing how your injuries affect daily life build a compelling picture of non-economic damages over time.
Tell your attorney about every new symptom

TBIs, psychological trauma (PTSD, anxiety), and chronic pain conditions often emerge weeks or months post-accident. Your attorney needs to know so they can be included in your damages claim before negotiation begins.
Do not discuss your case with anyone except your attorney

Not on the phone. Not to friends. Not to family. Anything said to a non-attorney is not protected by privilege and can be subpoenaed. Your attorney is your only safe channel.
Know Missouri's 5-year statute of limitations

RSMo 516.120 gives you 5 years to file a personal injury claim. But waiting hurts your case — evidence degrades, witnesses forget, and insurance companies become less cooperative. Don't mistake a long deadline for unlimited time.

Legal Context

Why Truck Accident Cases Are Different from Car Accident Cases

A semi-truck collision isn't just a "bigger car accident." Federal law governs commercial trucking under FMCSA regulations — and those regulations create legal obligations that can mean the difference between a small settlement and a life-changing verdict.

FMCSA Violations That Win Cases

Hours-of-service violations (fatigued driving), inadequate pre-trip inspections, improper load securement, banned driving while using handheld devices, operating with a suspended CDL, and failure to conduct proper driver qualification. Each violation is a separate basis for negligence — and in some cases, punitive damages.

Missouri also allows claims against the trucking company under respondeat superior (employer liability for employee actions) and direct negligence theories — negligent hiring, negligent entrustment, and negligent supervision. A well-investigated truck accident case may have five or more defendants, each with separate insurance policies.

⚠️ The Rapid-Response Problem

Major trucking companies maintain relationships with law firms and investigators who deploy to accident scenes immediately after a crash is reported. Their goal: document facts that minimize the company's liability. You are unrepresented during this critical window. Calling an attorney within 24 hours — even before you're discharged from the hospital — is the single most important step you can take.

Common Questions

Truck Accident FAQs

How long do I have to file a truck accident lawsuit in Missouri? ▼

Missouri's statute of limitations for truck accident personal injury claims is 5 years from the date of the accident (RSMo 516.120). However, if a government vehicle was involved, you may have as little as 90 days to file a notice of claim. Critical evidence — including ELD data and black box data — can be overwritten within 30 days. Contact an attorney immediately.

What evidence disappears fastest after a truck accident? ▼

Electronic logging device (ELD) data is typically overwritten every 30 days. Dashcam footage loops even faster — sometimes within 72 hours. The truck's black box (ECM) stores only the most recent data. Skid marks fade and road debris is cleared. A lawyer can send a preservation letter demanding all of this evidence before it's gone.

Should I talk to the trucking company's insurance adjuster? ▼

No. Trucking companies often deploy rapid-response teams to accident scenes within hours. Their goal is to minimize your claim. Do not give a recorded statement, sign any releases, or accept any early settlement offer before speaking with a personal injury attorney. Anything you say can be used to reduce your compensation.

Who can be held liable in a truck accident besides the driver? ▼

Multiple parties may be liable: the truck driver, the trucking company (respondeat superior), the cargo loading company (if improper loading caused the crash), the truck manufacturer or parts supplier (if mechanical failure was involved), and the shipper in some cases. An attorney conducts a rapid multi-defendant investigation to identify every liable party.
