Mike’s Quick Answer
Dashcam video can be powerful evidence of how a crash happened. It may show traffic signals, lane position, following distance, weather, pedestrians, surrounding vehicles, and the seconds before impact. It can also disprove a driver’s first impression. The video is not perfect evidence. A wide-angle lens changes perceived distance and speed, a timestamp may be wrong, audio can add context or confusion, and the camera may not capture what happened beside or behind the vehicle. Preserve the original memory card and file before the camera’s loop-recording system overwrites it.
Save the Original Before Watching It Repeatedly
Many dashcams record in a loop. When the card fills, the device writes over older footage. Turn the camera off or remove power safely after the incident, following the manufacturer’s instructions, so routine driving does not erase the event.
Copy the original file to secure storage without converting, trimming, adding captions, or uploading it through an app that compresses the video. Keep the memory card in a labeled protective case.
Context Extends Beyond the Moment of Impact
Preserve several minutes before and after the collision. Earlier footage may show traffic flow, a vehicle weaving, the color sequence of a signal, or visibility. Later footage may capture statements, vehicle positions, and conditions before cars are moved.
Audio deserves the same care. A horn, turn signal, navigation prompt, or spontaneous statement may matter. Private conversation can also raise scope and privacy questions that a lawyer should address.
Video Must Be Authenticated and Interpreted Fairly
Authentication means showing that the exhibit is what its proponent says it is. Testimony from the owner, file information, device settings, continuity, and an unchanged original can establish reliability.
Perspective can mislead. Lens distortion, frame rate, mounting position, darkness, and missing angles should be considered before drawing conclusions about speed or distance. An engineer may be needed in a serious disputed crash.
The Camera Can Help or Hurt Either Side
A client should not delete footage because part of it is unfavorable. Once a claim is reasonably expected, selective destruction can create a spoliation issue that is worse than the original fact.
I review the complete video against physical evidence, statements, police measurements, and vehicle data. A dashcam is a witness with a fixed viewpoint. It can be excellent, but it does not see everything.
Frequently Asked Questions
Should I give the dashcam card to the police?
Cooperate with lawful requests, but first make a verified copy if feasible and document who receives the original. Obtain legal advice in a serious or disputed crash.
Can I post the video online?
That is usually a bad idea during an active claim. Posting can spread an incomplete clip, invite commentary, affect privacy, and create avoidable evidentiary disputes.
What if the timestamp is wrong?
A wrong clock does not necessarily make the video useless. Other evidence can establish timing, but the discrepancy should be disclosed and explained.
