Common Car Accident Injuries

The sudden, violent force of a car accident can change your life in a fraction of a second. In the moments after a crash, you will likely feel disoriented or numb. You might even feel like you’ve escaped unharmed, even though your vehicle is destroyed.

However, the adrenaline from the collision often masks serious injuries that can surface hours, days, or even weeks later. Pain that starts as a dull ache can quickly evolve into a debilitating condition that affects your ability to work, care for your family, and enjoy your life.

Understanding the nature of your injury is the first step, but if you decide to pursue a personal injury claim, it’s only the beginning. The first challenge is showing that your injuries were caused by the accident. Then the real challenge is proving the extent of your injury to an insurance company that is financially motivated to downplay your pain.

Let’s review some of the most common car accident injuries and, more importantly, learn about the evidence required to build a strong, successful car accident personal injury claim in New Jersey and Pennsylvania.

Key Takeaways

Proof is Paramount: A medical diagnosis is only the beginning. Building a successful car accident claim requires gathering specific evidence (like consistent treatment records, expert reports, and objective test results) to prove the full severity of your injury and link it directly to the crash.
Each Injury Has a Unique Challenge: Insurance companies dispute injuries in different ways. Proving a soft tissue injury like whiplash relies on documenting your treatment consistently, while proving a herniated disc involves using MRI evidence to overcome claims of a “pre-existing condition.”
“Invisible” Injuries are Real and Provable: For injuries like concussions and TBIs, the most powerful evidence often comes from neuropsychological testing and testimony from family and colleagues who can describe the changes in your cognitive function and personality.

Whiplash and Soft Tissue Neck Injuries: The “Invisible” Injury

Whiplash is one of the most common—and most frequently disputed—injuries in car accidents, especially in rear-end collisions. Even low-speed impacts can generate enough force to cause significant harm to the delicate structures of the neck.

What is Whiplash?

Whiplash is a non-medical term for a neck sprain or strain. It occurs when your head is thrown violently back and forth, stretching and tearing the muscles and ligaments in your neck beyond their normal range of motion. The result is pain, stiffness, headaches, and sometimes radiating pain into the shoulders and arms.

How is Whiplash Diagnosed?

A significant challenge with whiplash is that it often doesn’t show up on standard imaging tests. X-rays can rule out fractures, and an MRI can rule out a herniated disc, but a “normal” scan doesn’t depict the pain you are experiencing. Whiplash diagnosis is typically based on:

A Physical Examination: Your doctor will test your neck’s range of motion, check for tenderness and muscle spasms, and test your reflexes.
Patient-Reported Symptoms: Your description of the pain, including its location, what exacerbates it, and how it affects your daily activities, is a critical diagnostic tool.

Proving Whiplash in a Personal Injury Claim

Because there is often no single “smoking gun” on an MRI, proving the severity of a whiplash injury requires building a comprehensive record of its effects on your life. An insurance adjuster will look for objective evidence, so we must provide it. This includes:

Consistent Medical Treatment: This is the single most important factor. Attending all of your doctor’s appointments and physical therapy sessions shows the insurance company that your injury is genuine and requires ongoing care. Adjusters often use gaps in treatment to argue you weren’t truly hurt or that the injury has healed.
Detailed Medical Records: Your doctor’s notes, which should document your specific pain levels, loss of range of motion, and prescribed treatments, form the core of your claim.
Physical Therapy Progress Notes: These records provide objective measurements of your limitations and document your slow, often difficult, recovery process.
Meeting the “Verbal Threshold” (New Jersey): In NJ, many auto insurance policies have a Limitation on Lawsuit or verbal threshold that prevents you from suing for pain and suffering unless your injury is severe and/or permanent. For whiplash, this often requires a certification from a physician stating that, within a reasonable degree of medical probability, the neck injury has not healed to a point where it can function normally and will not reach that point with further medical treatment.

Herniated Discs and Back Injuries: A Common Source of Chronic Pain

The force of a car accident can place enormous pressure on the spine, leading to damage to the vertebral discs that cushion your vertebrae. A herniated disc is a serious injury that can cause chronic pain and long-term disability.

What is a Herniated Disc?

You can think of the discs in your spine as tiny jelly doughnuts. They have a tough outer wall and a soft, gel-like center. A herniated (or bulging, or ruptured) disc occurs when the trauma of a crash causes the outer wall to tear, allowing the soft center to push out and press on the spinal cord or nearby nerve roots. This pressure can cause intense local back pain as well as radiating pain, numbness, tingling, or weakness in the arms or legs (also known as sciatica).

How Are Herniated Discs Diagnosed?

Unlike whiplash, a herniated disc is a structural injury that can be clearly seen on an imaging test. These injuries should appear on the following tests:

An MRI Scan: This is the gold standard for diagnosing a herniated disc. An MRI provides a detailed picture of the soft tissues of the spine, clearly showing the location and size of the herniation and its impact on the surrounding nerves.
EMG/Nerve Conduction Studies: If you have radiating symptoms, your doctor may order these tests to measure the electrical activity of your nerves and muscles, confirming that the herniated disc is causing nerve damage (radiculopathy).

Proving a Herniated Disc Was Caused by the Accident

The primary defense tactic insurance companies use is to claim your herniated disc is a pre-existing, degenerative condition due to age or a prior injury, and not the accident. Your personal injury lawyer’s job is to prove them wrong. We do this with:

The Objective MRI Evidence: The image itself is powerful proof of the injury’s existence.
Medical Expert Opinion: Your legal team will work with your treating physicians or retain outside medical experts to write a report that causally links the trauma of the car accident to the disc herniation. The expert will explain how the biomechanical forces of the collision were sufficient to cause the rupture.
A Clear “Before and After”: A skilled legal professional will document your physical state before the accident to provide evidence that you lived an active, pain-free life, and only sought treatment for back pain after the collision. These details are crucial to defeating the pre-existing condition argument.
Records of Pain Management: Evidence that you have undergone treatments like physical therapy, chiropractic care, and even painful epidural steroid injections demonstrates the severity of your pain and your efforts to find relief.

Traumatic Brain Injuries (TBI) and Concussions: More Than Just a Bump on the Head

A traumatic brain injury is any injury that disrupts the normal function of the brain. It can happen even if your head doesn’t directly strike an object, because the violent jarring of the brain inside the skull during a crash is enough to cause damage. TBIs exist on a spectrum, from a mild concussion to a severe, life-altering injury.

What is a TBI?

Even a mild TBI (concussion) can have serious consequences, including headaches, dizziness, memory problems, concentration issues, and emotional changes like irritability or depression. Symptoms of “post-concussion syndrome” can last for months or even years, impacting every aspect of your life, especially the ability to return to work.

How Are Brain Injuries Diagnosed?

Diagnosing a severe TBI with a skull fracture or brain bleed is straightforward with a CT scan or MRI. Diagnosing a concussion is far more difficult. Medical professionals use the following steps to diagnose a mild brain injury:

Initial Hospital Evaluation: This is to rule out life-threatening bleeding or swelling.
Clinical Diagnosis: Most concussions are diagnosed based on the symptoms you report, such as headache, confusion, or amnesia of the accident.
Neurological or Neuropsychological Testing: For ongoing symptoms, a specialist may conduct a series of tests to objectively measure deficits in memory, processing speed, and executive function.

Proving the Impact of a Concussion or TBI in a Civil Personal Injury Claim

A brain injury is defined by its impact on your ability to function. The evidence needed to prove this goes far beyond medical scans. Experienced injury lawyers will provide as much evidence as possible to support a claim for TBI, including:

Objective Test Results: Data from neuropsychological exams provide scientific proof of your cognitive struggles.
Testimony from Family, Friends, and Co-workers: Statements from people who knew you before and after the accident are incredibly powerful. They can address changes in your personality, memory lapses, newfound irritability, or struggles with tasks that were once easy for you.
A Detailed Personal Journal: Keeping a headache diary, or a daily journal that tracks your symptoms, such as light sensitivity, dizziness, and brain fog, and how they impact your ability to work, engage in hobbies, or participate in daily life, is crucial evidence of your pain and suffering.
Vocational Expert Reports: If the TBI impacts your ability to do your job, a vocational expert can analyze your condition and provide a professional opinion about how your earning capacity has been diminished.

How Long Do I Have to File a Personal Injury Lawsuit?

If you suffered injuries in an accident that was caused by someone else’s negligence, carelessness, or intentional actions in New Jersey or Pennsylvania, you only have two years to file a lawsuit against the responsible parties. Both the New Jersey statute of limitations and Pennsylvania’s statute of limitations provide the same short timeframe to pursue your legal rights, all while you are still recovering from your injuries.

Gathering evidence, finding witnesses, consulting with medical professionals, and building a strong case takes time and effort. Don’t wait to contact a reputable personal injury law firm to help protect your rights and ensure your claim is filed before the deadline passes.

Your Injury is More Than a Diagnosis—It’s Your Future Story

Insurance companies see injuries as line items on a balance sheet. They are trained to dispute, delay, and deny legitimate claims. Proving the true extent of your injuries requires telling a complete, evidence-based story of how the accident has impacted your health, your finances, and your life.

Building a strong personal injury claim involves more than just a single medical report; it requires a carefully constructed case built from consistent medical care, expert opinions, and detailed documentation.

Your next step is to partner with lawyers who understand your injuries, how they occurred, and who is responsible for the harm you’ve suffered. Together, you can fully explain the impact your injuries have had on your life, which means you are more likely to recover all losses in your personal injury case.
