Dash Cam Evidence Guide for Truck Drivers

Key Takeaways

• Dash cam footage is evidence, not a highlight reel. Preserve the original file before sharing any copy — originals carry more credibility and more metadata than copies.
• Know before an incident which system is in your truck, where the footage is stored, and who your company safety contact is for preservation. Figuring this out under pressure costs time you don't have.
• Footage can help you — and can also raise questions you'll need to address. Preserve everything and let the claim process determine what is relevant.

What dash cam footage is and isn't

Dash cam footage records video from a fixed camera angle — typically forward-facing through the windshield — at whatever resolution and frame rate the system supports. It captures what the camera sees during the recording window, not everything that happened. Camera angle, resolution, lighting conditions, and the timing of event triggers all shape what the footage shows and what it doesn't.

Footage is evidence when it exists and when it's preserved. A recording that was overwritten, deleted, or exported in reduced quality before anyone reviewed it loses most of its value. Treat the original file the way you would treat any other physical evidence from an incident.

How camera systems work in practice

Most fleet dash cam systems record continuously and overwrite older footage on a loop — typically every few hours to a few days depending on storage capacity. Event-triggered recordings are flagged and protected from overwrite, but only within the system's design. A hard braking event may protect a 30-second clip; a low-speed contact that doesn't trigger the G-sensor may not protect anything.

Some systems transmit footage to a cloud platform automatically. Others store it locally on an SD card or internal memory. Know which type is in your truck before an incident, because the preservation steps differ.

What to do when an incident occurs

Do not copy, delete, or trim the footage before notifying your company safety contact. The first step is reaching that contact so they can initiate preservation through the correct system channel. Note the time, date, and approximate location of the incident — clip duration and system logs are tied to timestamps, and accuracy about timing helps pull the right recording segment.

Do not share footage with anyone outside the company without authorization. Your job as the driver is to preserve and report; handling the footage from that point is your company's responsibility.

Who handles footage requests

Insurers, attorneys, and investigators may request dash cam footage as part of a claim or litigation. All such requests should go through your company's safety or legal contact — not directly to you.

Do not describe what the footage shows to anyone involved in a claim or investigation without guidance from your safety or legal contact. The contents of the recording are part of the claim file, not a subject for informal discussion.
