Vehicle GPS Data as Evidence in Accident Cases

Published on March 1, 2026 | By Digital Evidences

When a vehicle accident occurs, determining exactly what happened in the moments before and during the collision is often the central question in litigation. Witness accounts can be unreliable, and physical evidence at the scene may be inconclusive. However, modern vehicles continuously record GPS and telemetry data that can provide an objective, timestamped record of the vehicle's movements, speed, and behavior. This data has become increasingly important evidence in accident cases.

What GPS Data Vehicles Store

Modern vehicles equipped with navigation and infotainment systems maintain detailed logs of GPS positioning data. These logs can include the vehicle's precise geographic coordinates at regular intervals, the speed at which the vehicle was traveling, the direction of travel, and timestamps for each recorded data point. Some vehicles also record acceleration and braking events, steering wheel angle, and whether safety systems like anti-lock brakes or electronic stability control were activated.

This data is stored in the vehicle's infotainment system, telematics control unit, or event data recorder. In many cases, the vehicle continues to store this information even after a collision, preserving a detailed record of the moments leading up to and during the accident. The data may persist for weeks or months, depending on the vehicle's storage capacity and usage patterns.

Extracting GPS Evidence with Berla iVE

Berla iVE is the leading vehicle forensics platform for extracting and analyzing GPS and telemetry data from automobiles. A certified Berla iVE examiner connects to the vehicle's diagnostic systems or directly accesses the infotainment module to create a forensic image of the stored data. This process preserves the evidence in its original state while allowing for comprehensive analysis.

Using Berla iVE, the examiner can reconstruct the complete travel history of the vehicle, mapping every route taken and every stop made. The software plots GPS coordinates on interactive maps, calculates speeds between data points, and generates visual representations of the vehicle's movements that are easy for judges and juries to understand. The tool also identifies when devices were connected via Bluetooth, calls were made or received, and navigation destinations were entered.

Applications in Accident Litigation

GPS data from vehicles has proven valuable in several types of accident cases:

• Speed Determination: GPS track logs can establish the vehicle's speed before, during, and after a collision, helping to determine whether speeding was a contributing factor.
• Route Reconstruction: The data shows exactly which roads the vehicle traveled and where turns or lane changes were made, providing context for the accident.
• Timeline Establishment: Precise timestamps on GPS data points help establish the exact time of the accident and the sequence of events leading up to it.
• Location Verification: GPS data can confirm or contradict a driver's account of where they were at a specific time, which is relevant in hit-and-run cases or disputed liability scenarios.
• Distraction Analysis: Records of phone connections, calls, and text message activity through the vehicle's hands-free system can indicate whether the driver was distracted at the time of the accident.

Event Data Recorders

In addition to GPS data, many vehicles are equipped with event data recorders that capture specific crash-related parameters. These devices record data such as vehicle speed, throttle position, brake application, seatbelt status, and airbag deployment in the seconds immediately before and during a collision. The data from event data recorders, combined with GPS track logs extracted through Berla iVE, provides a comprehensive picture of the accident that is difficult to dispute.

Preserving Vehicle Evidence

If a vehicle is involved in an accident that may lead to litigation, it is important to preserve the vehicle's electronic data as soon as possible. Vehicle data can be overwritten by subsequent trips, system updates, or repair shop activities. In some cases, insurance companies or repair facilities may reset or erase vehicle systems before the data can be forensically preserved. Attorneys should consider requesting a forensic preservation of vehicle data at the earliest opportunity, ideally before the vehicle is repaired, sold, or scrapped.
