Witness and Camera Evidence

Collecting Witness Statements: Timing Is Everything

Memory degrades rapidly after a traumatic event. A witness who can recall the traffic-light color and the speed of the approaching vehicle ten minutes after the crash may struggle with those details a week later. Collecting witness information at the scene — names, phone numbers, and a brief account of what they saw — is one of the highest-value actions you can take.

Do not wait for the police to interview every witness. Officers may not arrive before some bystanders leave, and their interviews may not cover every detail relevant to your claim. Ask witnesses directly: what did you see before the collision? Where were you standing? Did you notice anything about the other driver's behavior?

Follow up within a day or two with a more detailed written or recorded statement. Ask the witness to describe what they observed in their own words, without leading questions. A contemporaneous statement obtained within 48 hours carries far more credibility than a recollection produced months later during litigation.

Surveillance and Traffic Camera Footage: Where to Look and How Fast

Camera footage provides objective visual evidence that does not depend on memory or perception. The challenge is identifying and preserving it before it disappears. Surveillance systems at businesses, banks, gas stations, and parking facilities often record exterior views that capture nearby roadways. Traffic-light cameras, highway monitoring systems, and toll-booth cameras are operated by government agencies. Residential doorbell and security cameras cover driveways and streets in many neighborhoods.

Walk the area surrounding the crash site and note every camera you can see. Look in all directions — a camera behind you may have captured the other vehicle's approach. Provide the locations to the responding officer and, separately, to your attorney.

Request footage immediately. Many commercial surveillance systems operate on short recording loops — footage is often overwritten within days or weeks depending on the system's storage capacity. Government-operated traffic cameras may retain footage longer, but access requires a formal request. Do not assume anyone will preserve footage without being asked.

Dash Cam Evidence: Your Own and Others'

If your vehicle has a dash cam, secure the footage before it is overwritten by new recording. Remove the memory card or transfer the files to a separate device. Do not continue using the camera on the same storage medium — recording over the crash footage destroys the evidence.

Other vehicles at the scene may also have dash cams running. Ask other drivers whether their cameras recorded the collision. Delivery vehicles, rideshare cars, and commercial trucks are increasingly likely to have forward-facing cameras. If the other driver is cooperative, request a copy of their footage at the scene. If they are not, your attorney can pursue it through discovery.

Dash cam footage captures real-time speed, traffic conditions, driver behavior, and the moments leading up to impact. It provides context that post-crash photographs cannot — showing what happened in the seconds before the collision that are most relevant to the fault determination.

Preservation Demands: Making Sure Evidence Survives

Identifying evidence is only half the job. Preserving it requires affirmative steps. A spoliation or preservation letter sent to the other driver, their insurer, nearby businesses with cameras, and any government agency operating traffic cameras puts them on formal notice that the evidence must be retained. Destruction after notice can result in legal sanctions.

For witnesses, preservation means obtaining their statements in writing or on recording as soon as possible. A witness who is willing to talk today may be unreachable in six months. Having a signed statement or a recorded account secures their testimony regardless of what happens later — whether they move, change their phone number, or simply lose interest in participating.

Your attorney can issue formal preservation notices, subpoena surveillance footage, and arrange professional witness interviews. The cost of these steps is modest relative to the value of the evidence they protect. In disputed-fault cases, preserved evidence is often the difference between a fair settlement and an outcome driven by the insurer's version of events.
