If you or somebody you care about has been injured or sustained property damage in an accident caused by a truck driver or trucking company in California, you should be able to recover compensation for your losses. After a truck accident, it is crucial to gather evidence promptly, as essential evidence can be lost or compromised if not collected and preserved right away. However, there are various steps that you need to take after these incidents occur, including obtaining records. 

It is important to recognize the different types of evidence—such as accident scene photos, black box data, and medical records—that should be preserved and secured after a truck accident to support your claim and prevent loss or alteration of crucial information. Here, we want to examine the various types of records that you or your attorney should try to obtain after a truck accident.

Introduction to Truck Accidents

Truck accidents are often devastating incidents that can lead to life-altering injuries, extensive property damage, and even fatalities. Unlike typical car accidents, truck accident cases are highly complex due to the involvement of multiple parties, such as the truck driver, the trucking company, and other vehicles involved in the crash. Establishing fault and determining liability are essential steps in any truck accident claim, as these factors directly impact your ability to recover fair compensation for your losses. Navigating the legal process after a truck accident requires a thorough understanding of the types of critical evidence needed to prove your case. 

An experienced truck accident attorney can make all the difference by gathering essential records, handling negotiations with insurance companies, and ensuring that your rights are protected throughout the process. Whether you are dealing with injuries, property damage, or emotional distress, having a knowledgeable legal team on your side is crucial for establishing fault and holding all responsible parties accountable.

Gathering Evidence at the Scene

Gathering evidence at the scene of a truck accident is one of the most important steps you can take to strengthen your case. Immediately after the crash, it is vital to document the accident scene thoroughly. This includes taking photographs and videos of the vehicles involved, any skid marks, vehicle debris, and damage to nearby property or traffic signs. Physical evidence such as broken parts, tire marks, and the position of the vehicles can provide valuable insight into the events leading up to the accident. Collecting witness statements and their contact information is also essential, as these individuals can offer unbiased accounts of what happened. Additionally, obtaining the police accident report and any other official documents from police officers or emergency services will help create a detailed record of the incident. 

Preserving evidence, including securing the truck’s event data recorder (EDR), is crucial, as this device can reveal important details about the truck’s speed, braking patterns, and actions taken by the driver before the crash occurred. By gathering and preserving this evidence, you lay the groundwork for a strong truck accident claim.

Medical Records and Treatment

After a truck accident, seeking immediate medical treatment is essential—even if you believe your injuries are minor. Some injuries sustained in truck accidents may not be immediately apparent, and delaying treatment can not only jeopardize your health but also weaken your truck accident claim. It is important to keep detailed medical records, including hospital bills, doctor’s notes, diagnostic test results, and records of ongoing treatment. 

These documents serve as solid evidence of the injuries sustained and the medical care required, supporting your claim for compensation. An experienced truck accident lawyer can help ensure that all relevant medical records are accurately documented and preserved, which is critical for proving the extent of your injuries and the financial impact of the accident. Properly maintained medical records can make a significant difference in the outcome of your case, helping you recover compensation for medical expenses, lost wages, and other damages.

Witness Statements and Testimony

Witness statements and testimony are invaluable in any truck accident case. Witnesses can provide an objective perspective on how the accident happened, which can be crucial for establishing fault and supporting your claim.

It is important to collect witness statements and their contact information as soon as possible after the accident, as memories can fade and details may be lost over time. These statements can help corroborate other evidence, such as police reports and medical records, and provide a clearer picture of the events leading up to the crash. 

An experienced truck accident attorney can assist in identifying and interviewing witnesses, ensuring their statements are properly recorded and, if necessary, preparing them to testify in court. By leveraging witness testimony, you can strengthen your case and improve your chances of securing fair compensation.

The Electronic Logging Device in a Truck Accident

Beginning in December of 2019, all truck drivers and carriers were required to carry electronic logging devices (ELDs) inside of their vehicles. These devices replaced paper logbooks to keep track of a truck driver’s hours of service. Driver logs, whether electronic or paper, are essential for verifying hours of service compliance and can serve as crucial legal evidence in truck accident cases. These hours of service are set forth by the Federal Motor Carrier Safety Administration (FMCSA).

Drivers are required to abide by the hours of service requirements in order to prevent the fatigued operation of a larger commercial truck. These requirements dictate how long a driver can operate during each workday and during the workweek. It is important to have these records when investigating a truck accident to ensure that drivers are abiding by the regulations set forth by the federal government. Employment records can also be important for establishing compliance with regulations and identifying potential employer negligence or pressure that may have contributed to the accident.

The Electronic Control Module

Just like airplanes have a “black box” that must be obtained after a crash occurs, so do most commercial trucks, which are equipped with an event data recorder (EDR), commonly referred to as a black box. The electronic control module (ECM) is that black box. This is a device that keeps track of various information related to the truck that can be obtained and used in the event an accident occurs. 

Black box data from the truck’s event data recorder is crucial for understanding the truck’s speed and actions before the accident. This can include information such as the driver’s speed, whether the driver used their brakes before an accident, how long the truck has been in operation, the last scheduled maintenance, and various other truck diagnostics that could be important. Official reports may reference or include black box data as part of the evidence.

Truck Company Maintenance Records

The FMCSA requires that trucking companies regularly inspect and maintain each vehicle in their fleet. Additionally, federal requirements dictate that records of inspection and maintenance must be kept on file for a certain amount of time. It is important to obtain these records, particularly if vehicle failure is suspected as a cause of the accident. Analyzing vehicle damage alongside maintenance records can help determine whether mechanical issues, negligence, or other factors contributed to the collision.

Mobile Device Records 

In many cases, distracted driving is a suspected cause of a truck crash. It is important to obtain the truck driver’s mobile device records or the mobile device records of a trucking company phone or device in possession of the driver. This could help show whether or not the driver was using the phone to talk to someone, browsing the Internet or social media, or streaming movies or TV shows.

Truck Collision Reconstruction

Truck collision reconstruction is a vital part of many truck accident cases, especially when the cause of the crash is disputed or multiple parties are involved. Accident reconstruction specialists analyze all available evidence—including physical evidence from the accident scene, witness statements, and police reports—to recreate the sequence of events leading up to the truck collision. This process can help determine the cause of the accident, identify driver negligence, and uncover issues related to vehicle maintenance or other contributing factors. 

An experienced truck accident lawyer will often work closely with accident reconstruction specialists to build a compelling case on your behalf. By thoroughly analyzing the evidence and reconstructing the accident, your legal team can establish fault, prove liability, and help you pursue fair compensation for your injuries and losses. This comprehensive approach ensures that truck accident victims have the strongest possible case when seeking justice and financial recovery.

Working With an Attorney

If you or somebody you care about has been injured in an accident caused by a truck driver or trucking company, you need to reach out to a Newport Beach truck accident attorney as soon as possible to schedule a consultation at (714) 241-4444 or complete a contact form. Not only will the lawyer help you gather all of this information, but they will also make sure that an investigation is conducted to gain any evidence needed to prove liability, including investigating the actions of the drivers involved. 

This can include photographs and video surveillance from the incident, statements from witnesses, and the police report. Working with insurance adjusters and filing an insurance claim with the insurance company is also crucial to support your case. A knowledgeable attorney can help you pursue a personal injury claim and handle personal injury claims after a truck accident, ensuring your rights are protected throughout the process.
