After a serious commercial truck or delivery vehicle accident, one of the most important witnesses may be a camera mounted to the windshield.
Dashcams have become increasingly common in commercial fleets. Depending on the system, cameras may record the road ahead, the truck’s interior, side views, or multiple angles simultaneously. When a collision occurs, that footage can provide powerful evidence of what happened in the seconds before impact.
But injured accident victims usually do not have direct access to it.
In most cases, the trucking company, commercial carrier, or fleet operator controls dashcam footage generated by equipment it owns or operates. If a fleet uses a cloud-based telematics provider such as Samsara or Lytx, the footage may physically reside on the provider’s servers while remaining under the fleet customer’s ownership or control. Samsara’s current terms, for example, state that its customer owns its “Customer Data.” Lytx similarly explains that it processes certain information on behalf of business clients and that its customers determine the purpose and use of data they collect through the system.
The situation can be different when an independent owner-operator owns or leases the truck and independently purchases and installs a dashcam. In that situation, the driver or the driver’s business may control the recording, subject to any applicable lease, carrier, insurance, or technology-provider agreements.
For someone injured in a commercial vehicle crash, however, who owns the footage is only part of the question. The more urgent issue is often how to make sure potentially critical video is preserved before it is automatically overwritten, deleted, or otherwise becomes unavailable.
Quick Takeaways
- Commercial dashcam footage is generally controlled by whoever owns or operates the camera system, which is often the motor carrier, trucking company, delivery company, or fleet operator.
- Cloud storage does not necessarily mean the technology provider owns the footage. Samsara expressly states that its customers own Customer Data, while Lytx describes itself as processing certain information at the direction of its business clients.
- An independent owner-operator may control footage from a personally purchased dashcam, although contractual arrangements can affect who has access and control.
- Dashcam footage can help establish fault by documenting lane position, traffic signals, following distance, driver behavior, roadway conditions, and the sequence of events before a collision.
- Video may be overwritten through routine retention systems, making prompt preservation extremely important after a commercial vehicle accident.
- California discovery law allows parties to seek electronically stored information that is within another party’s possession, custody, or control, and electronic information may also be sought from third parties through a subpoena.
- A crash victim does not have to own the video for it to become evidence in a personal injury lawsuit.
Who Typically Owns or Controls Commercial Dashcam Footage?
There is no single rule that says every commercial dashcam recording belongs to the truck driver or every recording automatically belongs to the trucking company.
Ownership and control depend on how the vehicle, camera, and fleet-management system are structured.
Company-Owned Trucks and Cameras
The clearest situation occurs when a trucking company owns the truck, purchases the camera system, installs it in its vehicle, and maintains the associated fleet account.
In that situation, the company will generally possess or control the equipment and resulting recordings.
This is common with:
- Tractor-trailer fleets
- Delivery companies
- Utility companies
- Construction companies
- Bus operators
- Rideshare or transportation fleets
- Plumbing, HVAC, and other service fleets
- Municipal and other commercial vehicles
The driver may appear in the recording and may be the person operating the vehicle, but that does not necessarily mean the driver personally owns the camera footage.
What If Samsara, Lytx, or Another Company Stores the Video?
Modern commercial dashcams are frequently part of larger video telematics systems.
Rather than simply saving a video to a memory card inside the truck, these systems may transmit footage and related vehicle information to cloud servers operated by companies such as Samsara or Lytx.
That creates an important distinction between where footage is stored and who controls the data.
Samsara’s current platform terms state that its customer owns all Customer Data accessible through its software. Its definition of Customer Data includes customer-specific information captured through installed Samsara hardware.
Lytx describes a similar customer-directed relationship. Its privacy policy states that its camera systems are provided to businesses and organizations and that, in certain circumstances, Lytx processes information on behalf of those clients. Another Lytx data policy says that the customer determines the purpose and use of data collected through enabled systems.
Therefore, it can be misleading to simply say, “Lytx owns the footage” or “Samsara owns the video” merely because the information is stored on their systems.
The fleet’s contract with its technology provider can be critical in determining ownership, access, retention, and control.
What If the Driver Is an Independent Owner-Operator?
Commercial trucking relationships can become more complicated when the person driving the truck is an independent owner-operator.
Suppose the driver:
- Owns the tractor;
- Purchases their own dashcam;
- Pays for the camera or cloud account; and
- Controls the recordings.
In that situation, the driver or the driver’s business may own and control the footage rather than the motor carrier whose loads the driver was hauling.
However, an owner-operator may also lease equipment, operate under another carrier’s authority, or use a fleet-provided camera system.
That is why attorneys investigating a commercial truck crash may need to determine:
- Who owned the truck?
- Who leased the truck?
- Who employed or contracted with the driver?
- Who purchased the camera?
- Who installed it?
- Who maintained the dashcam account?
- Where was the video stored?
- Who could access or download it?
- What retention policy applied?
- Was a third-party fleet management company involved?
Answering those questions helps identify who should receive a preservation request and where the footage may ultimately be obtained.
Why Can Dashcam Footage Be So Important in a Truck Accident Claim?
Truck accidents often produce competing versions of events.
A commercial driver might say another vehicle suddenly entered their lane. The injured motorist may say the truck drifted over without warning.
Dashcam video can sometimes replace that dispute with an actual recording.
Video footage may help establish issues such as:
- Which vehicle entered another lane
- Whether a driver ran a red light or stop sign
- Whether the truck was following another vehicle too closely
- Whether traffic had stopped before impact
- Road and weather conditions
- Construction zones
- Visibility
- Unsafe passing
- Sudden lane changes
- Whether a vehicle cut in front of the truck
- The timing and sequence of a multi-vehicle collision
Attorneys who handle commercial truck litigation identify dashcam footage as particularly useful because it can document driver conduct and the sequence of events in ways witness recollections sometimes cannot.
Pines Salomon likewise identifies onboard camera footage among the evidence that may be investigated following a San Diego truck accident.
Driver-Facing Cameras May Reveal an Entirely Different Story
Many commercial camera systems do more than record the roadway.
A driver-facing camera may capture what was occurring inside the cab before a collision.
Depending on the equipment and available recording, footage could potentially show whether a commercial driver was:
- Looking at a cellphone
- Eating or drinking
- Looking away from traffic
- Appearing fatigued
- Reaching for an object
- Interacting with an electronic device
- Reacting to a roadway hazard
- Paying attention immediately before impact
This information can become particularly important when a trucking company or its insurer argues that the driver responded appropriately.
Video may also work together with other electronic evidence.
For example, an attorney might compare camera footage with:
- Electronic logging device records
- GPS information
- Engine control module or event data recorder information
- Dispatch communications
- Cellphone records
- Vehicle speed and braking information
Pines Salomon has previously explained that commercial vehicle “black box” information can help reveal braking, speed, acceleration, and other vehicle-operation information surrounding a collision.
When electronic systems tell a consistent story, they may provide powerful evidence about how a crash occurred.
Dashcam Footage Can Also Help the Trucking Company
Video evidence is not inherently favorable to the injured person.
A dashcam could show that another motorist abruptly cut in front of the commercial truck, ignored a traffic signal, or otherwise caused the collision.
That is one reason commercial fleets invest in these systems in the first place. Dashcam and telematics providers market their products partly as tools that can provide objective evidence and help fleets evaluate disputed incidents.
An experienced personal injury attorney should therefore seek the footage to discover what actually happened – not simply assume that it will support one side.
Why Does Dashcam Footage Need to Be Preserved Quickly?
Commercial dashcam systems are not necessarily permanent video archives.
Some systems continuously record and overwrite older video. Others retain particular events for only a defined period. Retention can depend on the equipment, subscription, company policy, storage capacity, event settings, and whether someone specifically saves a clip.
Transportation attorneys and fleet-industry sources specifically recommend creating policies for which accidents trigger preservation and how long footage should be maintained because dashcam systems may otherwise operate under normal retention cycles.
Truck litigation practitioners likewise warn that dashcam footage can be overwritten as part of routine data-retention processes if a litigation hold is not put in place.
There is no universal rule that every trucking dashcam keeps footage for the same number of days.
That makes speed important.
Waiting months to investigate whether footage exists can mean discovering that a recording once existed but has since been overwritten.
What Is a Spoliation or Preservation Letter?
One of the first steps a commercial vehicle accident attorney may take is sending a preservation letter, sometimes called a spoliation letter or litigation hold notice.
The letter informs the trucking company and other relevant parties that evidence connected to the accident should be preserved.
A properly tailored request may identify evidence such as:
- Forward-facing dashcam footage
- Driver-facing camera footage
- Side- or rear-facing cameras
- Video from a specific period before and after impact
- Audio associated with the footage
- Original video files
- Metadata
- Telematics records
- GPS history
- Black box or engine data
- Electronic logging device records
- Driver communications
- Dispatch records
- Maintenance information
A commercial truck crash may involve numerous forms of electronic evidence, which is why the preservation request should generally extend beyond the single video clip showing impact.
Prompt investigation is important in trucking cases because dashcam footage, black box data, driver records, and other evidence may be lost if it is not preserved.
Does a Preservation Letter Automatically Give You the Video?
No.
This distinction is important.
A preservation request essentially says:
“Do not destroy or overwrite this evidence.”
It does not necessarily require a company to immediately provide all requested information to the injured person before litigation.
Obtaining the footage may require another legal mechanism.
How Can an Attorney Obtain Commercial Dashcam Footage in California?
If the trucking company voluntarily provides the footage during the claim investigation, obtaining it may be relatively straightforward.
If it refuses, California’s civil discovery rules can provide mechanisms for securing electronically stored evidence once litigation is underway.
Discovery From the Trucking Company
California Code of Civil Procedure § 2031.010 permits a party to demand electronically stored information within another party’s possession, custody, or control.
If the trucking company controls its dashcam system or can retrieve footage from its fleet-management provider, relevant recordings may therefore potentially become the subject of a formal discovery demand.
Subpoenas to Third Parties
Sometimes relevant electronic information is held by an entity that is not itself a defendant in the lawsuit.
California Code of Civil Procedure § 1985.8 specifically permits civil subpoenas seeking electronically stored information and allows the requesting party to specify how that data should be produced.
Depending on the circumstances, that can become important when evidence is maintained by:
- A telematics provider
- Fleet-management company
- Maintenance contractor
- Another motor carrier
- Business with surveillance cameras
- Other third-party data custodian
Whether a particular company can or must produce footage depends on the facts, its contractual relationship, the scope of the request, and applicable discovery rules.
What Happens If the Trucking Company Deletes the Footage?
The answer depends heavily on when and why the information disappeared.
Not every missing video proves misconduct.
Electronic systems routinely overwrite old information. California law expressly recognizes that electronically stored information can be lost through the routine, good-faith operation of an electronic information system, while also stating that this rule does not eliminate obligations to preserve discoverable information.
The situation can become much more serious when relevant evidence is intentionally suppressed after a party knows it should be preserved.
California Evidence Code § 413 provides that when determining what inferences to draw from evidence, a factfinder may consider a party’s willful suppression of evidence.
California’s civil jury instructions also address circumstances involving willful suppression of evidence.
The consequences of lost evidence are highly case-specific and can depend on issues such as:
- Whether litigation was pending or reasonably anticipated
- Whether the evidence was relevant
- Whether the company knew it existed
- Whether preservation had been requested
- Whether deletion was intentional or routine
- Whether comparable evidence remains available
- What prejudice resulted from the loss
For this reason, sending a prompt and specific preservation notice can become an important part of protecting an injury claim.
Why the Original Video File Can Matter More Than a Screen Recording
An insurer might send a claimant a short cellphone recording of a computer monitor showing the collision.
That is not necessarily the same as obtaining the original electronic evidence.
The native video file may contain information that helps establish authenticity and context, including:
- Creation dates
- Timestamps
- File metadata
- Camera identifiers
- Associated telematics information
- Additional frames before or after the clip supplied
- Other camera angles
Video evidence generally must be shown to be authentic, relevant, and sufficiently reliable before being admitted at trial. Truck litigation practitioners therefore emphasize preservation of original files and information establishing their source and integrity.
An attorney may seek enough surrounding footage to understand the entire event rather than accepting an isolated few seconds selected by the opposing party.
What Other Video Should Be Investigated After a Commercial Vehicle Accident?
The commercial vehicle’s dashcam is only one potential camera.
Depending on where the accident occurred, video might also come from:
- Another truck
- Passenger vehicle dashcams
- Nearby businesses
- Gas stations
- Restaurants
- Apartment buildings
- Homes equipped with security cameras
- Construction sites
- Parking garages
- Municipal or transportation cameras
Third-party video can sometimes capture an angle the truck’s own camera missed.
It is important to investigate these sources promptly as well because private surveillance systems frequently operate under their own retention and overwrite schedules. The growing availability of both commercial dashcams and third-party surveillance footage has made video an increasingly important source of evidence in truck collision investigations.
You Do Not Have to Own the Dashcam Footage for It to Help Your Case
A crash victim might reasonably wonder:
“If the trucking company owns the footage, doesn’t that mean they can simply keep it from me?”
Not necessarily.
Ownership and discoverability are different questions.
You do not need to own another company’s business record in order for relevant information within its possession, custody, or control to potentially become discoverable in litigation. California law expressly provides for discovery of electronically stored information from another party and, in appropriate circumstances, through third-party subpoenas.
The key is identifying that the evidence exists and taking action to preserve and obtain it.

Dashcam footage can sometimes answer questions that would otherwise remain contested for years.
It may show exactly when a commercial truck changed lanes, whether traffic had stopped before impact, what the driver was doing inside the cab, or whether another vehicle actually caused the collision.
But useful footage cannot strengthen a personal injury case if it disappears before anyone asks for it.
That is why identifying, preserving, and obtaining electronic evidence can be particularly important in the days and weeks following a serious commercial vehicle accident.
