You were recording. The other driver ran the red light, clipped your bumper, and now they’re telling their insurance company it was your fault.
The footage is sitting on your SD card right now. What you do in the next few hours determines whether that video actually helps you — or gets overwritten before you can use it.
This guide covers exactly what to do: how to preserve footage immediately after an accident, how to submit it to your insurer, how it’s used in a claim, and what its limitations are so you’re not blindsided.
Step 1: Preserve the Footage Before It’s Gone
The most important thing you can do after an accident is lock the footage immediately. Dash cams use loop recording — they continuously overwrite old footage to make space for new recordings. If you drive home and forget about it, the video of your accident could be gone within hours.
How to Lock Footage
- G-sensor auto-lock: Many cameras automatically lock a clip when they detect a sudden impact. This is a safety net, not a guarantee — minor collisions sometimes don’t trigger it.
- Manual lock button: Most dash cams have a dedicated button (often labeled with a lock icon) that locks the current and previous clip. Press it within a few minutes of the accident.
- Manual file copy: Remove the SD card and copy the files to a computer as soon as possible. This is the most reliable method.
Don’t Remove the SD Card at the Scene
Wait until you’re safely away from traffic and have exchanged information with the other driver. Removing the card at the scene could create confusion, and you may need the camera running if any dispute arises on the spot.
What the Files Look Like
Dash cam footage is typically saved in 1–3 minute segments named by date and time. Look for files in a folder labelled “Emergency,” “Locked,” or “Event” — these are clips the camera has already protected. Footage in the standard “Normal” folder is at risk of being overwritten.
Step 2: Review the Footage Before Submitting It
Before you send anything to anyone, watch the footage yourself. You need to know exactly what it shows — and what it doesn’t.
What to Look For
- Clear view of the impact or the moments leading up to it
- Other vehicle’s license plate (front or rear camera)
- Traffic signals, lane markings, or road signs that establish right-of-way
- Timestamp and GPS overlay — confirms when and where the incident happened
- Audio — if your camera records audio, it captures everything said in the car
What It Might Not Show
Dash cams have blind spots. A side-impact collision may not appear on a forward-facing camera. If the incident happened in a parking lot and your camera wasn’t in parking mode, you may have nothing at all. A front and rear setup closes many of these gaps.
If the footage doesn’t help your case, you’re not obligated to volunteer it — but be honest with your insurer about what you have. Concealing relevant evidence can complicate your claim later.
Step 3: Submit Footage to Your Insurance Company
Once you’ve reviewed the footage and decided to use it, here’s how to submit it effectively.
How Insurers Prefer to Receive It
- Upload through the claims portal: Most insurers now accept video uploads through online claim portals. MP4 and MOV formats are almost universally supported.
- Email to your claims adjuster: If you have a direct contact, send a compressed file or a cloud-hosted link (Google Drive, Dropbox).
- Physical media: In rare cases, especially for complex claims, you may be asked to provide footage on a USB drive or SD card.
Before You Submit
- Make a copy for yourself — always keep your own copy of the original file
- Note the file timestamp — confirm it matches the time of the accident
- Include context — write a brief note explaining what the footage shows and which clips are relevant
What Happens After You Submit
A claims adjuster reviews the footage alongside the police report, witness statements, and the other party’s account. The video is one piece of evidence, not automatic proof. Adjusters assess camera angle limitations and what can and can’t be conclusively established from the footage.
Step 4: Using Footage as Legal Evidence
If your claim escalates to a lawsuit or involves serious injuries, dash cam footage can become formal legal evidence. This changes the rules around how it’s handled.
Notify Your Attorney Immediately
If you have legal representation, tell them about the footage before you do anything else. They will advise on evidence preservation requirements and may need to submit footage through proper legal channels.
Chain of Custody Matters
For footage to be admitted in court, you need to demonstrate it hasn’t been altered. Keep the original file untouched on the SD card, work only from copies, and document when you reviewed it and who you shared it with.
State Laws on Audio Recording
If your dash cam records audio, some states have two-party consent laws that could complicate the admissibility of the audio portion. Video is generally unaffected, but worth discussing with your attorney if audio is relevant. Check your state’s dash cam recording laws →
What Dash Cam Footage Can and Can’t Do
| Footage CAN establish | Footage often CAN’T establish |
|---|---|
| Speed and direction of vehicles | Driver intent or state of mind |
| Whether traffic signals were obeyed | Events outside the camera’s field of view |
| Sequence of events before the collision | Fault in complex multi-vehicle incidents |
| Other vehicle’s license plate | Clear details in very low light (budget cameras) |
| Road and weather conditions | Side or rear impacts (front-only cameras) |
A budget camera with poor night vision may capture something, but may not capture enough to be useful. This is one of the strongest arguments for investing in a quality dash cam before you need it.
Frequently Asked Questions
Will my insurance premium go up if I submit dash cam footage?
Not if the footage supports your account. If the video clearly shows the other driver was at fault, your insurer is better positioned to defend the claim. Footage that confirms you were at fault may affect your rate, but that outcome was already determined by what happened — the camera just documented it.
Do insurance companies accept dash cam footage?
Yes. All major US insurers accept dash cam footage as supporting evidence in auto claims. It’s reviewed as one piece of evidence alongside police reports, witness statements, and the other party’s account.
What if the other driver had a dash cam too?
Their footage can be requested by your insurer or attorney. If it contradicts their account of events, it strengthens your case. If it supports their version, it may be used against you — this cuts both ways.
How long should I keep dash cam footage after an accident?
Keep all footage until the claim is fully closed and any appeal period has passed — minimum 3 years, longer if litigation is involved. Store it in at least two separate locations (external hard drive plus cloud storage).
What’s the best dash cam for insurance claims?
Look for GPS logging, at least 1080p resolution, and strong night vision. The BlackVue DR970X 2CH Plus leads on footage quality. For more options at every budget, see our full dash cam roundup →
Bottom Line
Dash cam footage is only useful in a claim if you know what to do the moment an accident happens. Lock the footage before it loops, review it before you share it, and submit it through the right channels to carry weight with an insurer or in court.
The camera you choose matters too. Low-resolution footage in poor lighting may not capture what you need when it counts most. If you’re relying on a dash cam for protection, it’s worth investing in one that delivers.
