When a commercial truck is involved in an accident, the most powerful piece of evidence may already exist on video. Dashcams and surveillance footage can show exactly how an accident occurred, who was at fault, and whether the trucking company or driver acted negligently. But can you legally obtain that footage in California? Here’s what you need to know.
Why Dashcam and Surveillance Footage Matter in Truck Accident Cases
Truck accidents often involve multiple parties such as the driver, the trucking company, cargo loaders, and sometimes even third-party maintenance contractors. In these complex cases, video evidence can make or break your claim. For instance:
Dashcams (mounted on the truck) may capture the driver’s actions, road conditions, and even potential distractions or violations before the collision.
Surveillance cameras from nearby businesses, intersections, or freeway systems may record the crash itself.
Body-worn or in-cab cameras used by some trucking companies can show whether the driver was fatigued, texting, or violating safety protocols.
These recordings provide objective, timestamped proof unlike witness statements that may conflict or fade over time.
Can You Legally Request Truck Dashcam Footage in California?
In California, dashcam and surveillance footage are considered discoverable evidence if they are relevant to your case. However, you generally cannot just ask the trucking company to hand them over voluntarily. In fact, to obtain these materials your attorney will typically use formal legal procedures such as:
Subpoena duces tecum- a court order compelling the trucking company to produce specific evidence
Discovery request- which requires the opposing party to provide relevant video data during litigation.
Preservation letter- sent immediately after the accident to prevent the company from deleting or overwriting footage
Under California Code of Civil Procedure § 2031.010, parties to a lawsuit must produce electronically stored information (including video) that is relevant and not privileged.
Can Footage Be Deleted Quickly
Many trucking companies use dashcams that automatically overwrite data every few days or weeks unless saved manually. Similarly, business surveillance systems may only retain recordings for 30 days or less. With that in mind, it is absolutely crucial to hire an attorney as soon as possible.
A lawyer can immediately send a spoliation letter, a formal notice instructing the trucking company to preserve all potential evidence. If they ignore it and erase footage intentionally, they can face sanctions or adverse inference rulings, meaning the court may assume the deleted evidence was unfavorable to them.
What If the Trucking Company Refuses to Hand Over the Footage?
If a trucking company denies access or submit claims the footage was lost, your attorney can:
File a motion to compel, asking the court to order the company to produce the video.
Subpoena third parties, such as traffic authorities or nearby businesses whose cameras may have captured the crash.
Request telematics data (speed, braking, GPS) from the truck’s onboard systems, which can corroborate your account even without video.
California courts take evidence spoliation seriously, so if the company is found to have destroyed or concealed evidence, it may strengthen your claim of negligence or recklessness.
What About Privacy Concerns?
California’s privacy laws, including the California Consumer Privacy Act (CCPA), protect individuals’ personal data, but they do not prohibit obtaining footage for legitimate legal purposes. Courts balance the privacy interests of drivers with the public interest in fair litigation.
As long as your request is specific, relevant, and not overly broad, the court can compel production under existing discovery rules. Personal information such as unrelated footage or internal company data may be redacted.
