Truck Accident Documentation FAQ

What do I do immediately after a commercial truck accident?

Check yourself for injury first, then others involved.

Call 911 if there are injuries, a fire risk, or a vehicle blocking a live traffic lane that can't be moved safely. Deploy emergency warning devices — triangles or flares — at the required distance behind the stopped vehicle.

If the truck can remain in position without creating additional hazard, leave it until authorities arrive. Vehicle position is evidence that can't be recreated once the truck moves.

Once the scene is stable, begin collecting the other party's information, photographing the scene, and noting witness contacts.

What information do I need to collect at the scene?

From the other driver: full name, license number, vehicle registration, insurance company name, policy number, and a contact phone number.

If the other vehicle is commercial, note the carrier name and DOT number from the door placard. Photograph rather than write down where possible — a phone photo of a license plate or insurance card is more accurate than handwritten notes taken under stress.

From law enforcement: the agency name, responding officer name, and report number. Photographs of both vehicles from multiple angles, road conditions, skid marks, and traffic control signs.

Witness names and phone numbers if anyone was present.

How long do I have to report a truck accident?

Timing requirements vary by what's being reported and to whom.

Your insurer's policy almost certainly requires prompt notice — many policies define this as within 24 to 48 hours of the incident. 15 set a separate recordkeeping obligation for carriers.

State motor vehicle accident report requirements add another layer. The safest approach is to notify your company safety contact the same day as the incident and let them coordinate insurer notification.

Don't assume that filing a police report satisfies your insurance notification requirement — those are separate obligations.

Should I admit fault or apologize at the scene?

No.

At-scene fault determinations are almost always incomplete — the driver doesn't know what other evidence exists, what the other party's account will be, or what investigation will later reveal. An apology or at-scene admission can be used against you in the claim process even if the full picture later shows shared or no fault on your part.

Keep communication at the scene factual: exchange information, confirm injuries, cooperate with law enforcement, and tell anyone who asks for a statement that your company safety contact or insurer will handle the review. That's not evasion — it's how the process is supposed to work.

What records do I need to preserve after a truck accident?

Preserve dash cam footage first — continuous-loop systems overwrite within 24 to 72 hours if a clip wasn't triggered and flagged.

Write your account of the incident as soon as possible while memory is fresh. Preserve ELD records for the incident day and surrounding period; some platforms have rolling retention schedules shorter than most people expect.

Export telematics data from the incident time window before it's overwritten. Collect photos, witness information, and the police report number at the scene.

Route all records through your company's safety contact or incident file, not your personal device or email.

Do I need a lawyer after a truck accident?

CrashProof Truck doesn't advise on whether you need legal representation — that depends on facts specific to your situation, the severity of the incident, and what's at stake.

What this site can say is that certain situations typically warrant getting a qualified attorney involved early: fatalities, serious injuries, cargo spills with environmental impact, citations, and any incident where an opposing party has retained counsel. Your company safety contact or insurer can help you understand when legal representation is recommended under your specific policy.

Don't make that decision based solely on how straightforward the scene looked.

What is post-accident drug and alcohol testing, and when is it required?

303.

Testing is required after certain crashes — the triggering facts involve fatalities, injuries requiring immediate medical treatment away from the scene, and tow-away situations. The exact triggering conditions and the time limits for completing testing are in the regulation; confirm them with your safety contact immediately after any serious incident, not after some delay.

The testing windows are measured in hours. A driver who was tested outside the allowed window, or not tested when required, creates a compliance issue that may become part of any subsequent investigation.

What's the difference between a driver incident report and a police report?

A police report is prepared by law enforcement based on what they observed at the scene and what parties reported.

A driver incident report is an internal company document completed by the driver, typically within 24 hours of the incident. They serve different purposes.

The police report is a third-party account used in claim handling and potentially in litigation. The driver incident report is an internal safety record that should capture what the driver observed before, during, and after the event — without speculation about fault or conclusions about what caused the crash.

Both matter, and neither substitutes for the other.

What should I not do after a truck accident?

Don't move the truck unless it's creating an active safety hazard.

Don't delete, overwrite, or share dash cam footage without going through your company safety contact. Don't give a recorded statement to another party's insurer or attorney without authorization.

Don't post about the incident on social media. Don't repair vehicle damage before the insurer or adjuster has inspected it.

Don't discuss fault, cause, or what you could have done differently with anyone at the scene or in the days immediately following — route those conversations through your safety contact or insurer.

How do I know whether my dash cam footage was automatically preserved?

Event-triggered clips — those flagged by hard braking, impact, or other configured thresholds — are generally protected from overwrite as long as the clip was captured successfully and storage capacity allows.

Continuous-loop recordings that weren't triggered are typically not protected and will overwrite on a rolling schedule. The safest approach after any significant incident is to treat the footage as unpreserved until you confirm otherwise.

Contact your safety contact or fleet manager the same day and have them initiate the preservation process — either locking the clip through the platform, pulling the SD card, or triggering a cloud backup — rather than relying on automatic preservation.
