A car accident claim is only as strong as the evidence behind it. Every assertion you make about how the accident happened, who was at fault, and how badly you were injured requires evidence to support it. This page covers the categories of evidence Georgia courts accept, how quickly critical evidence disappears after an accident, and the one tool that can force preservation before it is too late.
This is the evidence hub. Each specific evidence type has its own detailed page linked below.
Evidence Categories
Physical Evidence
Physical evidence includes the vehicles themselves, debris patterns at the scene, skid marks on the road surface, gouge marks in pavement, road conditions, and the accident scene as it existed at the moment of impact. Physical evidence is powerful because it cannot be fabricated after the fact. The deformation pattern on a vehicle encodes information about impact speed and angle. Debris field distribution reveals the point of impact. Skid marks reflect braking patterns and pre-impact speed.
The problem: physical evidence disappears. Vehicles get repaired or scrapped. Skid marks fade with traffic and weather. Scenes change as roads are resurfaced and debris is cleared. What was not documented in the first 24 to 48 hours may be permanently gone.
Documentary Evidence
Documentary evidence includes police reports, medical records, insurance correspondence, bills, pay stubs, employment records, and maintenance logs. These records carry built-in credibility because they were created before litigation, in the regular course of business, and for purposes other than supporting a lawsuit.
For how police reports specifically function as evidence, see Police Reports in Georgia Car Accident Cases. For medical records and their role in proving causation, see Medical Records in Georgia Injury Claims.
Digital Evidence
Digital evidence is increasingly the most decisive category in Georgia car accident cases. Dashcam footage, traffic camera recordings, cell phone records, social media posts, Event Data Recorder (EDR/black box) data, GPS location data, and app usage logs capture what actually happened rather than what parties remember happening.
Digital evidence has two defining characteristics: it is often the strongest proof available, and it disappears fastest. Dashcam loop recordings overwrite within 24 to 72 hours. Business surveillance cameras cycle their storage within 7 to 30 days. Cell carrier records have retention periods measured in months, not years. The urgency of preserving digital evidence cannot be overstated.
When preserving dashcam footage, the method matters for admissibility. Removing the SD card from the dashcam immediately, before the device records over the accident footage, is the critical first step. Creating a forensic copy that preserves metadata (timestamps, GPS coordinates, device identifier) protects against authentication challenges. A dashcam video copied informally with stripped metadata is vulnerable to challenge on authentication grounds.

Testimonial Evidence
Witness testimony includes statements from bystanders who observed the accident, the parties themselves, passengers, and emergency responders. Independent witnesses with no stake in the outcome are the most credible. Party testimony is expected to be self-serving but remains admissible.
Witness memory degrades rapidly. Contact information obtained at the scene within hours of the accident is exponentially more valuable than trying to locate witnesses weeks later. A written or recorded statement taken from a witness within days of the accident preserves their account while memory is fresh.
Expert Evidence
Expert testimony translates raw evidence into conclusions that juries can evaluate. Accident reconstruction experts analyze physical evidence to determine how the crash occurred. Medical experts establish causation between the accident and the injuries. Economic experts calculate lost earning capacity and future damages. Life care planners project lifetime medical needs. Biomechanical experts analyze the relationship between crash forces and injury patterns.
Georgia courts apply the Daubert reliability standard under O.C.G.A. § 24-7-702 to determine whether expert testimony is sufficiently reliable to be admitted. For expert witness qualification, costs, and selection criteria, see Expert Witnesses in Georgia Car Accident Cases.

How Quickly Evidence Disappears
This is the most important practical information on this page. Evidence has a shelf life, and for the most valuable types, that shelf life is measured in hours or days.
| Evidence Type | Preservation Window |
|---|---|
| Dashcam footage (loop-recording devices) | 24 to 72 hours before overwriting |
| Business and traffic surveillance cameras | 7 to 30 days before storage cycles, depending on the system |
| 911 recordings and dispatch logs | Weeks; request through Georgia's Open Records Act promptly |
| Cell tower and carrier data | 6 to 18 months depending on carrier and data type |
| Event Data Recorder (black box) data | At risk whenever the vehicle is repaired, started, or scrapped |
| Witness memory | Degrades significantly within days; substantially unreliable after weeks |
Every day that passes after the accident is a day that specific evidence may cease to exist. Waiting is not a neutral choice. It is an active decision to accept that some evidence will be gone when your case needs it.
The Spoliation Letter: Forcing Evidence Preservation
A spoliation letter is a formal written notice sent to any party possessing evidence relevant to your accident, demanding that they preserve it and warning of legal consequences if it is destroyed. Sending a spoliation letter establishes that the recipient knew the evidence was relevant to anticipated litigation, making any subsequent destruction intentional rather than routine.
Who Receives a Spoliation Letter
The at-fault driver’s insurance company. The at-fault driver personally (through their attorney if represented). Any repair shop where damaged vehicles have been taken. Businesses or property owners with surveillance cameras covering the accident location. Trucking or fleet companies (for commercial vehicle accidents). The at-fault driver’s employer (if driving for work).
When to Send
Within 24 to 48 hours of the accident if possible. For commercial vehicle cases, immediately. Trucking companies have document retention policies that can result in rapid destruction of logs, ELD data, and communications that would otherwise be preserved.
A preservation demand can be sent before a lawsuit is filed. It does not require active litigation to be effective. Under SB 68, the discovery stay provision (which can freeze formal evidence gathering for up to 90 days after a defendant files a motion to dismiss) makes pre-suit spoliation letters even more critical. Evidence that would normally be obtained through early discovery is at risk of disappearing during the stay period. Preserve first, litigate second.
What the Letter Contains
The letter identifies the accident (date, time, location), specifies the categories of evidence to be preserved (surveillance footage, vehicle EDR data, driver logs, communications records, photographs, GPS data), identifies the possessor’s legal obligation not to destroy relevant evidence once on notice, and states that destruction after receipt of the letter may result in adverse inference instructions, sanctions, or other penalties.
How Evidence Is Authenticated and Admitted
For evidence to be admissible in Georgia courts, it must be properly authenticated under the Georgia Evidence Code (O.C.G.A. Title 24, effective January 1, 2013). Authentication means establishing that the evidence is what it claims to be.
Photographs and videos require testimony or circumstantial evidence establishing when and where they were taken and that they accurately depict what they purport to show. Physical objects require chain of custody documentation. Business records, including medical records and employment records, are admitted through business records exceptions to the hearsay rule, typically via affidavit from the records custodian.
Authentication failures are the most common basis for excluding otherwise relevant evidence. A video with stripped metadata, a medical record without custodian verification, or physical evidence with a broken chain of custody creates arguments for exclusion that might otherwise be avoidable.
SB 68 Changes to Evidence Admissibility
SB 68 (effective April 2025) made two significant changes to what evidence is admissible in car accident cases. Seatbelt non-use is now admissible on issues of negligence, comparative fault, and causation, where it was previously excluded under the seatbelt gag rule. The amounts actually paid by insurance for medical treatment are now admissible alongside billed amounts, where they were previously restricted under the collateral source rule. SB 68 modified the collateral source rule for medical damages, allowing defendants to introduce evidence of insurance payment amounts. Both changes affect trial strategy and settlement calculations. For full analysis, see Georgia SB 68 Tort Reform and Car Accident Claims and The Seatbelt Defense in Georgia Car Accident Cases.
This guide covers admissible evidence in Georgia car accident cases as of March 2026. The Georgia Evidence Code (O.C.G.A. Title 24, effective January 1, 2013) governs admissibility. SB 68 (April 2025) changed seatbelt evidence and medical payment evidence admissibility. Laws change. This information is educational and does not constitute legal advice.
