Ticketed After a Crash? Get a Forensic Reconstruction That Stands Up in Court.
We analyze dash-cam, photos, scene geometry, and EDR (“black box”) to compute speed, angles, and time-distance—then deliver clear, defensible exhibits to challenge citations.
How Crodymi LLC Helps Fight Crash-Related Tickets
Dash-Cam Speed Extraction
Frame-by-frame analysis with scale calibration (lane widths, markers) to quantify the other driver’s speed and acceleration.
- Work-zone speed verification
- Signal-state timing correlation (if visible)
- Uncertainty bands reported
Time–Distance & Perception–Reaction
We test whether a reasonable driver in your position could safely complete a maneuver, given approach speeds and sight distance.
- PRT ranges applied (alert vs. delayed)
- Stopping/braking distance modeling
- Conflict timing and gap acceptance
Work-Zone & Signage Review
Checks for proper signing, taper length, and posted limits. We document compliance issues that affect driver expectations.
- Posted vs. actual speed use
- Visibility/obstruction analysis
- Night/Weather adjustments
EDR Correlation (Black Box)
When available, we download and correlate pre-impact speed, brake, and throttle with the video/scene timeline.
- Airbag deployment checks
- Event timing alignment
- Consistency validation
Court-Ready Exhibits & Testimony
We deliver annotated frames, diagrams, and (when needed) short animations—with affidavits or expert testimony.
- Scaled diagrams & timelines
- Plain-English findings summary
- Depositions & trial support
Video Enhancement & Authentication
Stabilization, de-blurring, and verification to ensure what’s shown is measurable and trustworthy.
- Chain-of-custody notes
- Compression artifact checks
- Lens distortion correction
Dash-cam, CCTV, phone video, photos, EDR, police diagrams
Report PDF, exhibits, speed tables, time-distance charts

Case Example: Left Turn in a Construction Zone — Ticket Dismissed
A driver turned left across traffic in a work zone (posted 30 mph). The oncoming vehicle struck the right side of the turning car.
Dash-Cam Speed Analysis
Frame sampling and distance calibration showed the oncoming motorist was traveling about 45 mph (~15 mph over the posted work-zone limit).
Perception–Reaction & Gap Assessment
Using typical perception–reaction ranges and measured sight distance, our model showed the left-turning driver had a sufficient gap and acted as a reasonable driver would at 30 mph traffic.
Outcome
Result: The reconstruction demonstrated that the collision was precipitated by the oncoming vehicle’s excessive speed. Citations against the left-turning driver were dismissed. (*Results vary by case.)
Common Citations & How Forensic Analysis Helps
| Citation | What We Show | Useful Evidence |
|---|---|---|
| Failure to Yield / Unsafe Left Turn | Gap acceptance and conflict timing; whether a prudent driver could complete the turn at posted speeds. | Dash-cam/CCTV, time–distance charts, work-zone speed check |
| Speeding (incl. Work-Zone) | Measured approach speed vs. posted limit; uncertainty bounds; corroboration with EDR if available. | Video frame sampling, scale calibration, EDR pre-impact data |
| Following Too Closely | Headway/time-gap, deceleration profiles, realistic stopping distance at prevailing speed. | Dash-cam with landmarks, braking distance model |
| Disregarded Signal/Sign | Signal state visibility/timing, lane markings, occlusions, and driver expectancy in work zones. | Video/photos, photogrammetry, signage audit |
