How to Preserve and Submit Dashcam Evidence for a UK Fleet Insurance Claim

The footage exists. What happens in the next hour decides whether it actually helps. Overwritten before it is locked, exported as a screen recording instead of the original file, or accompanied by a driver’s guess at fault rather than the facts, good dashcam evidence can lose most of its value before it ever reaches an insurer.

This guide covers what UK fleet operators need to do: lock footage correctly, export it in the right format, report the incident without undermining your own position, and coordinate all of it remotely. Written for taxi, PCO, car rental, and dealership fleets handling incidents at scale.

Lock the footage immediately

Even if your dashcam uses a G-sensor to auto-lock incident footage, do not rely on it. Sensitivity varies by device: a low-speed impact may not trigger it, and on a busy taxi or rental vehicle the loop can overwrite unprotected footage within hours.

The moment a driver calls in, the first instruction is: press the emergency button to lock the clip manually. Most dashcams write this footage to a protected folder the loop cannot reach.

At fleet scale, this is where things consistently fail. Drivers under stress do not reliably press buttons, and by the time the vehicle returns to depot the window may already have closed. A connected dashcam that transmits footage to the cloud without any driver action removes this dependency entirely. Once secured, export it correctly.

Exporting footage correctly: format and file integrity

Submit the original file. Not a screen recording, not a trimmed clip from a phone. The original MP4 or AVI from the SD card or cloud storage preserves GPS coordinates, timestamps, and device metadata that establish an unbroken chain of evidence.

UK legal guidance from solicitors specialising in collision claims is consistent on this: do not edit, annotate, or add text overlays to the footage before submitting it. Edited footage invites challenge to its integrity. If context is needed, such as what conditions were like or what the driver observed, provide it in a separate written statement alongside the footage, not embedded in the file.

What to say (and not say) when reporting the incident

Call your insurer immediately and mention at first contact that dashcam footage exists. Keep the initial report factual: what happened, where, when, which vehicles were involved. Do not speculate about fault before reviewing the footage.

Two points specific to fleet operations. First: instruct drivers not to share footage on social media or hand it to the other party at scene. Second: under PACE 1984, police can seize a dashcam or SD card if they believe it contains evidence of an offence. The correct response is to refer police to the fleet manager or legal department, not hand over the device at scene. Speak to your legal team about the right protocol for your operation before an incident occurs.

Coordinating footage requests from drivers as a fleet manager

A post-incident protocol must exist before any incident occurs. Not an informal phone call policy, but a written checklist drivers know about in advance.

At minimum: driver contacts fleet manager immediately, fleet manager retrieves footage remotely if the system allows, a copy is secured before police arrive. For 4G connected systems, this can happen within minutes. For depot-based SD card systems, the fleet manager should accompany police to the depot rather than leaving the driver to handle it alone. Once police seize a device, you are not legally entitled to a copy during their investigation.

Interior and audio recording: consent considerations for passenger vehicles

Taxi and PCO operators fitting interior cameras operate under specific UK GDPR rules. Video recording of passengers is permitted with the correct signage. Continuous audio recording is not: the only legal exception is a panic button that triggers short-duration audio in an emergency. Violating this risks regulatory consequences including potential GDPR action and licence review. TfL’s CCTV guidelines for licensed taxis and PHVs set out the compliance requirements in full.

Mandatory requirements: “CCTV in operation” signage at entry points and inside the vehicle; verbal notification for visually impaired passengers; footage access restricted to authorised personnel only; council-approved and tamper-proof systems for licensed taxis and PHVs. For the full compliance picture, the taxi dashcam guide for PCO and taxi operators covers these obligations in detail.

A real example: how dashcam footage settled a fleet claim

In 2017, Fleet News documented a case where a UK fleet avoided a disputed £16,000 third-party claim after dashcam footage proved the driver was not at fault in a red-light collision. The other party’s insurer withdrew once footage was shared. The case is from 2017, but in documented cases the same dynamic holds: footage showing clearly who was not at fault has changed an insurer’s position quickly.

City of London Police data shows crash-for-cash fraud cost the UK £70 million between June 2021 and July 2024. Staged incidents rely on there being no objective record of what happened. Dashcam evidence removes that condition.

How Traknova’s 4G dashcam simplifies footage retrieval

The failure point in most fleet incidents is the step that depends on a driver pressing a button under stress. Traknova’s 4G connected dashcam removes that dependency. Footage is transmitted to the cloud continuously, so the fleet manager can retrieve it remotely after a call, without waiting for the vehicle to return to depot.

Frequently asked questions

Can dashcam footage be used against me in a claim?

Yes. If footage shows fault on your driver’s part, it will be treated as evidence of that. This is not a reason to avoid dashcams: it is a reason to review footage before deciding what to submit.

How long should footage be retained after an incident?

Until the claim is fully resolved and all appeal windows have closed. For non-incident footage, ICO guidance implies that one week is a reasonable baseline for business dashcam use.

Can footage be submitted directly to police?

Yes, via the National Dash Cam Safety Portal. Select your local force, follow the upload process, and ensure quality is sufficient to identify number plates. This is separate from your insurer submission. Ask your insurer or broker whether they have a secure upload portal, as most major UK fleet insurers now accept footage that way rather than by email.
