The Purpose of Accident Reconstruction

Even when a serious motor vehicle crash does take place, it is not always easy to determine the exact cause of the crash. Several witness statements, the absence of hard evidence and differing versions of events can make it challenging to prove liability. It is often essential to determine the order of events that took place up to the injury incident when determining duty and the damages resulting from the collision in injury claims. One way to analyze available evidence to develop a better understanding of the sequence of an incident is by accident reconstruction.

After a big crash, numerous people are looking for information from an Arizona car accident lawyer so they can better comprehend how evidence can affect their claim. Accident reconstruction uses the information gathered at the scene of the accident, vehicle damage, roadway conditions and any available documentation to determine the circumstances of the accident. While each case involves different facts, it is important for an accident victim to have some idea of how evidence can be used to help settle the case and how it can be used in court proceedings.

What Is Accident Reconstruction?

Accident reconstruction involves analyzing the evidence to find out how the accident may have happened. Investigators evaluate the physical evidence, vehicle movement, roadway conditions, and other measurable factors rather than just relying on witness statements, to determine the sequence of events that have taken place before, during and after the crash.

It can be performed in cases where the responsibility for the accident is contested, in multi-vehicle accidents, in serious personal injury accidents, or when there is major property damage. Accident reconstruction can also help to shed light on factors that may not be immediately evident after the accident, through analysis of objective evidence.

The sections of formation that are generally looked at are:

  1. Vehicle damage patterns
  2. Skid marks and roadway debris found on the roadway
  3. Traffic signal timing
  4. The design and current situation of the road
  5. Weather and visibility
  6. Photographs taken from the scene
  7. CCTV or road traffic camera images 
  8. When available, event data recorder (EDR) information 

All of the evidence helps to build an overall picture of the accident. 

Importance of Crucial Evidence Along the Process

Accident reconstruction is based on careful and thorough evidence collection and preservation, then a careful examination to identify the factors that contributed to the accident. The information that can be obtained right after the accident can be the most valuable for two reasons: First, the roadway conditions, vehicle locations, and other physical evidence can alter over the course of time. Second, information collected early after an accident is often the most useful.

Information from a variety of sources is analyzed and synthesized by investigators to identify similarities and differences. They are not restricted to using one piece of evidence, but rather they look at several pieces of evidence to understand what transpired before the collision.

Common Evidence Used 

Police accident report  Records first impressions and remarks.
Vehicle damage Supports the assessment of impact points and impacts.
Situation documentation Maintains a record of the condition of the roadway and the position of vehicles.
Statements from the witnesses  Gives observations from a person or the people during the accident.
Camera footages  May capture the impact or things that happened just before the impact.
Event data recorder (EDR) Records some of the information that is required to operate a vehicle before the accident. 

A multi-source evidence approach can lead to more reliable understanding of the cause of the accident. 

Accident Reconstruction and Injury Claims Explained 

When determining liability is an issue, the importance of accident reconstruction can be considerable in evaluating the conflicting stories of the accident. Physical evidence can be used to determine if speeding, inattentive driving, stop at red lights, unsafe lane changes, or other factors played a role in the crash.

Accident reconstruction can also help in the following areas:

  1. Providing information on what happened 
  2. Identifying contributing factors
  3. Assessing pre-crash vehicle dynamics 
  4. Supporting liability assessments
  5. Describing multi-vehicle crashes 
  6. Ensuring that information is available to people through an unbiased process during settlement 

The reconstruction process does not take precedence over other evidence, but is rather a supplement to medical records, police reports, photographs, and witness statements in a comprehensive assessment of what happened.

Using Legal Preparation to Support Reconstruction 

Accident reconstruction is just one aspect of a larger injury claim. Legal preparation includes getting the evidence ready for insurance negotiations and/or court action, if required.

Lawyers will examine the accident reports, obtain medical records, save photos, get repair quotes and more, and keep records of employment, showing financial losses. The materials used help to link the physical evidence from the reconstruction process to the injuries and damages sustained by the accident victim.

Document preparation can also help to minimize the loss of key evidence over time. Organized evidence can aid in a better understanding of liability and damages in both settlement and litigation.

Frequently Asked Questions

What is accident reconstruction?

Accident reconstruction is an investigation process used to investigate physical evidence, vehicle damage, roadway conditions, and other physical information to determine the cause or how the motor vehicle accident likely occurred.

When and how is accident reconstruction used?

It’s often employed when someone’s liability is in question, if there have been serious injuries, in a multi-vehicle crash, or when the circumstances surrounding the crash are unclear.

During an accident investigation, what sort of evidence is crucial?

Items such as police reports, photographs of the scene, damage to the vehicle, witness accounts, video surveillance of the scene, roadway evidence, information from the event data recorder (EDR) and medical records can all be used to aid in the analysis.

Do all car accidents need accident reconstruction?

No. A lot of claims may be settled without the requirement for the documentation. In general, reconstruction will be more useful when there is a question about how the collision occurred.

How can the reconstruction of an accident help to affect settlement negotiations?

Yes. It can be useful to have a detailed reconstruction to help determine liability and to gather objective information that can be used for discussions of responsibility and compensation.

Conclusion

If the injury victim has an understanding of the process for accident reconstruction, he or she will be able to better understand the importance of evidence in a motor vehicle accident case when it comes to determining liability. When a reconstruction occurs it provides a valuable insight into how an accident has occurred and what circumstances could have contributed to the crash if any, by reviewing and analysing all physical evidence, vehicle damage and other available information.

These findings, along with careful legal documentation and preparation, can aid in productive settlement discussions and well-informed legal decision-making. People who’ve experienced a serious accident may want to speak with Brown & Hobkirk, PLLC
