On May 20, 2024, at approximately 10:15 AM, plaintiff Marcus Williams (driving a 2020 Honda Accord, Georgia plate ABC-1234) and defendant Kevin Park (driving a 2022 Ford F-150, Georgia plate XYZ-5678) collided at the intersection of Peachtree Street and 14th Street in Midtown Atlanta. Williams was traveling northbound on Peachtree; Park was traveling eastbound on 14th. The collision occurred in the center of the intersection. Williams's vehicle sustained $34,200 in damage; Williams suffered a cervical strain and mild concussion (3-day hospitalization, $8,500 in medical bills). Atlanta PD Traffic Unit responded and issued an accident report assigning 50/50 fault, finding that "both drivers failed to exercise due caution entering the intersection." Williams disputes the equal-fault finding, arguing he had a green light and Park ran a red. Williams filed a negligence action in Fulton County Superior Court seeking 80% fault allocation to Park — total damages claimed: $42,700 (vehicle) + $8,500 (medical) + $15,000 (pain and suffering) = $66,200. Park counter-claims Williams was speeding and entered on a stale yellow.
Atlanta PD Traffic Accident Report
Officer Darnell Washington responded at 10:22 AM. Report assigns 50% fault to each driver. Finding: "Both drivers failed to yield right of way." Notes: "No independent witnesses located at scene. Both drivers claim green light. Intersection traffic camera system confirmed offline for maintenance since 05/18/2024 (two days prior to accident)." Key fact: the city's traffic camera that would have definitively resolved the signal dispute was offline. Williams's attorney argues the 50/50 finding is a default when the officer cannot determine fault — not an independent factual determination.
Plaintiff's dashcam footage (Garmin 67W)
Williams's forward-facing dashcam (Garmin 67W, 2K resolution, GPS-synced timestamp): Shows Williams approaching the intersection at 10:14:52. At 10:14:54, the traffic signal is visible and appears green for northbound traffic. From 10:14:55 to 10:14:58 (3 seconds), the video freezes on a single frame — the image is static but the GPS timestamp continues advancing. At 10:14:58, the video resumes showing the moment of impact (Park's F-150 entering from the right). Plaintiff argues: the green light is clearly visible at 10:14:54, 4 seconds before impact — a normal interval for an intersection approach. Defense argues: the 3-second freeze is suspicious and could indicate tampering or a memory card error that also affected the signal-state capture; the light may have changed to red during the frozen interval.
Defendant's dashcam status (missing footage)
Park's 2022 Ford F-150 is equipped with a factory-installed forward camera (Ford Co-Pilot360). Park states the camera "wasn't recording that day" because he had "turned off the dashcam feature to save storage." Ford's technical documentation confirms the Co-Pilot360 dashcam can be toggled off in settings. However: (1) the system's default is "always on"; (2) Park's vehicle diagnostic log (obtained via subpoena from Ford) shows the dashcam was actively recording from 9:00 AM to 10:10 AM that morning — then was manually disabled at 10:10 AM, just 5 minutes before the accident. Plaintiff argues: disabling the camera 5 minutes before the accident suggests Park knew he was about to engage in risky driving (running a light). Defense argues: Park routinely toggles the feature off and the timing is coincidental; the diagnostic log proves nothing about the accident itself.
Intersection scene photographs and measurements
Atlanta PD photographs and measurements taken at 10:35 AM: Point of impact is approximately 8 feet into the intersection from the northbound lane (Williams's direction), and centered within the eastbound through-lane (Park's direction). Williams's Honda shows right-side front-quarter damage (passenger side); Park's F-150 shows front-end damage. Skid marks: none from Williams; 12-foot skid mark from Park's F-150 beginning approximately 6 feet before the point of impact. Plaintiff's accident reconstructionist argues: Park's 12-foot skid mark indicates Park saw Williams and braked late — consistent with Park entering the intersection on a red or late yellow. Defense argues: the impact position 8 feet into the intersection suggests Williams was traveling at significant speed — possibly indicating Williams entered on a yellow turning red.
Williams's medical records and vehicle repair estimate
Grady Memorial Hospital ER (May 20, 2024): cervical muscle strain (whiplash), mild concussion with brief loss of consciousness at scene, CT scan negative for intracranial hemorrhage. Hospitalized 3 days for concussion monitoring. Total medical bills: $8,500. Peachtree Collision Center estimate: $34,200 for right front-quarter panel, passenger door, suspension components, and airbag replacement. Williams claims an additional $15,000 in pain and suffering (ongoing neck stiffness, 6 weeks off work as a delivery driver — documented by employer letter). Total damages: $66,200. Park disputes the pain-and-suffering figure as inflated and challenges causation for the 6-week work absence.
Dashcam forensic analysis (plaintiff's expert)
Digital forensics expert Dr. Nina Alvarez examined Williams's Garmin 67W SD card. Findings: "The 3-second freeze at 10:14:55–10:14:58 is consistent with a known firmware bug in Garmin 67W units running firmware v4.60 (Williams's firmware version confirmed). Garmin issued a patch for this bug in July 2024. The freeze is caused by a buffer overflow during high-bitrate recording at intersections with complex visual scenes. The file's hash integrity is intact — there is no evidence of post-recording editing or tampering. The green light visible at 10:14:54 is the last captured frame before the freeze." Defense objects: Alvarez was retained by plaintiff and may be biased; her "firmware bug" explanation has not been independently verified by Garmin; the fact remains that the signal state during the frozen 3 seconds is unknown.
Marcus Williams (plaintiff)
The plaintiff driver; age 34; works as a delivery driver for a logistics company; no traffic violations in 5 years
I had a green light — I'm 100% certain. I was going through the intersection at normal speed, maybe 30–32 mph in a 35 zone. Then out of nowhere, this truck came flying in from my right. I barely had time to react. The next thing I remember is the airbag going off. My dashcam shows the green light right there. The 3-second freeze is a camera glitch — it happens sometimes with that model. I didn't touch the file.
Kevin Park (defendant)
The defendant driver; age 29; marketing manager; has one prior moving violation (speeding, 2022, 15 mph over)
My light was green — I had a green when I entered the intersection. He must have run the red. I was going maybe 25 mph. I saw him at the last second and hit the brakes but couldn't stop in time. My dashcam wasn't recording because I turned it off earlier that morning — I do that sometimes when the storage is full. The timing was just a coincidence.
Dr. Nina Alvarez (digital forensics expert, plaintiff's witness)
Ph.D. in computer science, Georgia Tech; specializes in dashcam and digital video forensics; 11 years of experience; has testified in 18 cases involving dashcam evidence authenticity
I examined the SD card from Mr. Williams's Garmin 67W. The 3-second freeze is a known artifact of firmware version 4.60 — Garmin acknowledged this bug and patched it in July 2024. The file's SHA-256 hash is consistent with an unmodified recording. There are no splice points, no metadata inconsistencies, and no evidence of post-capture editing. The green light visible in the last frame before the freeze (10:14:54) is the best available evidence of the signal state at that moment. I cannot state what the light showed during the 3-second gap — but I can confirm the footage has not been altered.
