The Electronic Control Module (ECM) or event data recorder in a commercial vehicle is a tool that, if accessed, can help you build your personal injury claim. These devices are a digital witness to what happened before and during the accident. It captures critical information that you can use to build your case. That includes speeds, braking, and overall function of the truck before an accident occurs.
By understanding ECM data in a truck accident claim, your attorney can better determine fault and show who caused the accident. Speak with a Birmingham truck accident lawyer about your case.
What ECM Data Captures
An ECM records critical information about the vehicle’s function as the driver operates it. Commercial trucks have this type of black box technology in place to conform with the Federal Motor Carrier Safety Administration’s rules. These black boxes track data such as:
- The date of the incident
- Engine hours
- Vehicle miles traveled
- Driver identification
- Speed and acceleration just prior to an impact
- Engine power and RPMs
- Brake pressure and throttle activity
- GPS coordinates
- Hours of service and rest breaks for drivers
Each of these factors can shed light on fault in an accident. They provide an unbiased assessment of the driver’s behavior and vehicle performance just before the incident.
How Black Box Data Sheds Light on Fault
Your truck accident attorney will seek this data from the commercial vehicle that struck you to analyze it. They are looking for clues about which slip-up or oversight allowed the incident to occur. Some examples of how this may be helpful include:
- Speed and acceleration of the vehicle. This information could show that the driver was driving above the posted speed limit at the time of the accident. It may demonstrate the driver was not slowing down enough around a curve.
- Seatbelt and airbag records. This information can help determine the severity of the impact and the resulting injuries.
- Throttle and gear activity. Changes to these details help demonstrate the driver’s behavior and driving patterns prior to the accident, indicating they were operating recklessly.
- Driver hours of service. Drivers who are tired, often in violation of the federal hours of service rules, are more likely to cause an accident.
- Brake usage. Did the driver apply the brake before the crash? If not, that may indicate the driver fell asleep at the time of the crash or was distracted rather than paying attention to the road conditions.
Every bit of information builds a clear picture of what went wrong that caused the accident. That information can then help build your case.
How to Get ECM Data from a Truck
Even when trucks have critical data recorded and stored on them, it is not simplistic to seek this information. However, your attorney will send a letter to the trucking company to preserve such critical data so it is not destroyed before the case is fully investigated. These details can be highly specific and may make it clear who caused the accident. Commercial trucking companies do not always want to share that information.
