The 10 Most Common Injuries in Rear-End Accidents

Rear-end collisions are among the most common types of motor vehicle accidents in the United States. Although these crashes are sometimes dismissed as minor fender-benders, the forces involved can cause significant injuries to the neck, back, head, shoulders, and other parts of the body. Even a collision at a relatively low speed can cause painful injuries that require emergency treatment, physical therapy, medication, or surgery.

One of the challenges with rear-end accidents is that injury symptoms do not always appear immediately. A driver or passenger may walk away from the accident believing they are unharmed, only to experience neck stiffness, headaches, back pain, dizziness, or numbness hours or days later. Some injuries, particularly traumatic brain injuries and spinal injuries, can have lasting consequences.

According to the National Highway Traffic Safety Administration (NHTSA), rear-end crashes accounted for approximately 28.4% of all reported motor vehicle crashes in 2022. There were approximately 1.69 million rear-end crashes that year, including 455,743 injury crashes and 2,817 fatal crashes. Rear-end collisions represented 27.4% of all injury crashes in the NHTSA data.

Understanding the injuries commonly associated with rear-end accidents can help victims recognize symptoms, seek appropriate medical treatment, and protect their legal rights. At John J. Malm & Associates, our Illinois car accident lawyers understand how devastating these collisions can be and help injured individuals pursue compensation when another driver’s negligence causes harm.

“Rear-end accidents are often treated as minor collisions, but the injuries they cause can be anything but minor. A person who suffers a neck injury, spinal injury, or traumatic brain injury deserves to have the full extent of that harm recognized. We believe in thoroughly investigating these cases and holding negligent drivers accountable for the consequences of their actions.” — John J. Malm, Naperville car accident attorney

Why Rear-End Accidents Cause Injuries

Rear-end accidents occur when one vehicle strikes the back of another vehicle. They frequently happen at traffic lights, intersections, stop signs, in congested traffic, and on highways when vehicles slow down unexpectedly.

When a vehicle is struck from behind, the occupants experience a sudden acceleration force. Their bodies may move forward with the vehicle while their heads, necks, and other body parts initially lag behind. This rapid movement can stretch muscles and ligaments, damage spinal structures, and cause occupants to strike interior vehicle surfaces. Common causes of rear-end collisions include:

• Distracted driving, including texting and using a cellphone.
• Following another vehicle too closely.
• Speeding or driving too fast for traffic conditions.
• Driving under the influence of alcohol or drugs.
• Fatigued or drowsy driving.
• Failing to recognize stopped or slowing traffic.
• Poor weather conditions and reduced visibility.
• Unsafe lane changes and aggressive driving.

The severity of an injury depends on several factors, including vehicle speed, the size and weight of the vehicles, the position of the occupants, whether seat belts were worn, and whether the vehicle’s safety systems functioned properly.

The 10 Most Common Injuries in Rear-End Accidents

The following are ten injuries frequently encountered after rear-end collisions. Not every accident causes these injuries, and the severity can vary considerably depending on the circumstances of the crash.

1. Whiplash and Neck Injuries

Whiplash is one of the most recognizable injuries associated with rear-end collisions. It occurs when the head is suddenly forced backward and then forward, causing the neck to move beyond its normal range of motion. This rapid movement can damage muscles, tendons, ligaments, nerves, and the discs in the cervical spine.

According to Mayo Clinic Health System, approximately 3 million whiplash injuries occur in the United States each year, with rear-end automobile accidents being a leading cause. Common symptoms of whiplash include:

• Neck pain and stiffness.
• Reduced range of motion.
• Muscle spasms and tenderness.
• Headaches near the base of the skull.
• Shoulder and upper-back pain.
• Tingling or numbness in the arms.

While many people recover within several weeks, some experience chronic neck pain and other complications that last for months or years.

2. Back Injuries and Lower Back Strains

Rear-end collisions can place tremendous stress on the thoracic and lumbar spine. Even when a vehicle sustains relatively minor property damage, the force of impact can cause the occupants’ bodies to move abruptly, stretching or tearing muscles and ligaments in the back.

Lower back injuries are particularly common because the lumbar spine supports much of the body’s weight and absorbs substantial force during sudden acceleration and deceleration. Common back injuries include:

• Lumbar muscle strains.
• Ligament sprains.
• Thoracic spine injuries.
• Muscle spasms.
• Soft-tissue damage.
• Chronic lower back pain.

Symptoms may include stiffness, difficulty bending, painful movement, and muscle spasms. Some victims have trouble sitting, standing, walking, or returning to physically demanding employment.

A study published in BMC Musculoskeletal Disorders examined 903 patients involved in motor vehicle collisions, including 546 rear-end collision patients. The researchers evaluated cervical and lumbar disc conditions and nerve-related symptoms, demonstrating the importance of examining spinal injuries following different types of vehicle impacts.

3. Herniated and Bulging Discs

The intervertebral discs act as cushions between the bones of the spine. These discs help absorb shock, distribute pressure, and allow the spine to move. However, the sudden forces generated during a rear-end collision can damage these structures.

A herniated disc occurs when the soft inner material of a spinal disc pushes through a tear or weakness in its outer layer. A bulging disc occurs when the disc extends beyond its normal boundaries. Depending on the location and severity of the injury, victims may experience:

• Severe neck or back pain.
• Pain radiating into the arms or legs.
• Numbness and tingling.
• Muscle weakness.
• Sciatica.
• Difficulty walking or standing for extended periods.

According to Cleveland Clinic, herniated discs can occur in the cervical or lumbar spine and may cause pain, numbness, and weakness when they irritate nearby nerves.  Treatment may involve physical therapy, anti-inflammatory medication, injections, or surgery. More serious cases may require a discectomy or spinal fusion.

4. Concussions and Traumatic Brain Injuries

A rear-end accident can cause a concussion or another traumatic brain injury (TBI), even when the victim does not strike their head against the steering wheel, dashboard, window, or headrest.

The sudden acceleration and deceleration forces can cause the brain to move inside the skull. This movement may disrupt normal brain function and produce symptoms that range from temporary confusion to significant cognitive impairment. Common symptoms include:

• Headaches and dizziness.
• Nausea and vomiting.
• Confusion or disorientation.
• Memory problems.
• Sensitivity to light and noise.
• Blurred vision.
• Difficulty concentrating.
• Changes in mood or sleep patterns.

The Centers for Disease Control and Prevention (CDC) identifies motor vehicle crashes as one of the important causes of traumatic brain injuries. The CDC reported more than 69,000 TBI-related deaths in the United States in 2021, illustrating the serious consequences associated with brain injuries.  A concussion should never be dismissed as a minor injury. Some symptoms may develop gradually, and victims experiencing a head injury should obtain prompt medical evaluation.

5. Headaches and Migraines

Headaches are another frequent complaint following rear-end collisions. They may develop because of whiplash, muscle tension, cervical spine injuries, nerve irritation, or a concussion. Some accident victims experience headaches that begin at the base of the skull and radiate toward the forehead. Others develop persistent migraines accompanied by nausea, visual disturbances, and sensitivity to light. Post-traumatic headaches can interfere with everyday activities, including working, driving, reading, and sleeping.

It is important to identify the underlying cause rather than simply treating the headache with over-the-counter medication. Persistent or worsening headaches following a collision may indicate a more serious injury requiring additional testing and treatment.

6. Shoulder Injuries and Rotator Cuff Tears

The shoulders can sustain significant trauma during a rear-end accident. Occupants may brace themselves against the steering wheel, dashboard, seat, or door when they anticipate an impact. The sudden movement can strain the shoulder joint and surrounding soft tissues. Common shoulder injuries include:

• Rotator cuff tears.
• Shoulder sprains and strains.
• Labral tears.
• Dislocated shoulders.
• Tendon injuries.
• Bursitis and inflammation.

Symptoms may include shoulder pain, weakness, reduced range of motion, and difficulty lifting or reaching overhead. Shoulder injuries can be particularly disruptive for people whose jobs involve lifting, carrying, reaching, or repetitive arm movements. Depending on the severity, treatment may require physical therapy, injections, or surgical repair.

7. Chest Injuries and Rib Fractures

Although rear-end accidents primarily produce forces that move occupants forward, the chest can also be injured. Seat belts are essential safety devices, but the restraint forces generated during a collision can cause bruising and other injuries. A driver may also strike the steering wheel, while a passenger may hit the dashboard or another part of the vehicle’s interior. Potential chest injuries include:

• Bruised ribs.
• Rib fractures.
• Chest wall contusions.
• Sternum injuries.
• Muscle strains.
• Internal injuries involving the lungs or other organs.

Symptoms can include chest pain, tenderness, difficulty taking deep breaths, and discomfort when coughing or moving. More serious chest injuries can involve a collapsed lung or internal bleeding. Difficulty breathing or severe chest pain following a crash requires immediate medical attention.

8. Wrist, Hand, and Arm Injuries

Drivers and passengers may instinctively brace themselves during a rear-end collision. Drivers may grip the steering wheel tightly, while passengers may extend their arms to protect themselves from the dashboard or other surfaces. These movements can result in injuries to the wrists, hands, elbows, and arms. Common injuries include:

• Wrist sprains.
• Fractured wrists.
• Broken fingers.
• Shoulder-to-arm soft-tissue injuries.
• Elbow injuries.
• Tendon and ligament damage.

A fracture may require immobilization, casting, or surgery. Severe injuries can also affect grip strength, fine motor skills, and the ability to perform everyday tasks.

9. Knee and Leg Injuries

The lower extremities can be injured when occupants are thrown forward or when their knees strike the dashboard, steering column, or other vehicle components.

Even in rear-end collisions where the front vehicle does not sustain substantial front-end damage, the movement of the occupants can place stress on the knees and legs. Potential injuries include:

• Knee sprains.
• Torn meniscus.
• Anterior cruciate ligament (ACL) injuries.
• Patellar fractures.
• Leg fractures.
• Soft-tissue injuries and bruising.

Knee injuries may cause swelling, instability, difficulty walking, and limited mobility. More serious ligament injuries can require reconstructive surgery and months of rehabilitation.

10. Facial Injuries, Cuts, and Dental Trauma

Facial injuries can occur when an occupant strikes the steering wheel, dashboard, window, or another object inside the vehicle. The sudden movement of the body may also cause a person’s face to strike a headrest or another passenger. Common facial injuries include:

• Cuts and lacerations.
• Bruising and swelling.
• Broken or chipped teeth.
• Jaw injuries.
• Facial fractures.
• Eye injuries.

Some facial injuries require stitches, reconstructive surgery, dental procedures, or long-term treatment for scarring. Beyond physical pain, visible facial injuries can have lasting emotional and psychological effects. Victims may experience embarrassment, anxiety, or diminished self-confidence because of permanent scarring or disfigurement.

Delayed Symptoms After a Rear-End Collision

One of the biggest mistakes accident victims make is assuming that they are not injured because they feel fine immediately after a collision. Adrenaline and the body’s initial stress response can temporarily mask pain and other symptoms. Injured individuals should watch for warning signs such as:

• Increasing neck or back pain.
• Persistent headaches.
• Numbness or tingling in the extremities.
• Dizziness or balance problems.
• Difficulty concentrating.
• Unexplained fatigue.
• Reduced range of motion.
• New or worsening muscle weakness.

Anyone experiencing these symptoms should seek medical attention. Severe headaches, loss of consciousness, confusion, repeated vomiting, weakness, or difficulty breathing warrant emergency evaluation.

What Should You Do After Being Injured in a Rear-End Accident?

Taking the appropriate steps after a rear-end collision can protect your health and preserve important evidence for a potential personal injury claim. Consider the following actions:

• Seek medical attention. Get evaluated even if you initially believe your injuries are minor.
• Call the police. Request that an accident report be prepared.
• Document the accident scene. Photograph vehicle damage, road conditions, traffic signals, and visible injuries.
• Exchange information. Obtain the other driver’s insurance and contact information.
• Identify witnesses. Collect names and contact information from anyone who observed the collision.
• Follow your treatment plan. Attend appointments and follow your healthcare provider’s recommendations.
• Preserve documentation. Keep medical bills, diagnostic reports, prescriptions, repair estimates, and records of missed work.
• Be cautious with insurance companies. Avoid providing recorded statements or accepting a settlement before understanding the full extent of your injuries.

These steps can help establish what happened, document the injuries, and demonstrate how the accident has affected your life.

How Are Rear-End Accident Injuries Treated?

Treatment depends on the type of injury, its severity, and the victim’s overall health. Some injuries resolve with conservative treatment, while others require extensive medical intervention. Common treatment options include:

• Emergency medical care: Evaluation, diagnostic imaging, and stabilization of serious injuries.
• Diagnostic testing: X-rays, CT scans, and MRIs to identify fractures, spinal injuries, and soft-tissue damage.
• Physical therapy: Exercises and rehabilitation to restore strength, flexibility, and mobility.
• Medication: Prescription or nonprescription medication to manage pain and inflammation.
• Injections: Epidural steroid injections or other procedures to address persistent pain.
• Surgery: Procedures to repair fractures, torn ligaments, damaged discs, or other serious injuries.
• Occupational therapy: Assistance with regaining the ability to perform everyday activities and return to work.

Some victims require treatment for months or years. In particularly serious cases, an accident may result in permanent disabilities, chronic pain, or an inability to return to their previous employment.

Who Is Liable for Injuries in an Illinois Rear-End Accident?

In many rear-end collisions, the driver who strikes another vehicle from behind is responsible because they failed to maintain a safe following distance, pay attention to traffic, or stop in time to avoid a collision. Under Illinois law, drivers have a duty to operate their vehicles safely and maintain control. Illinois Vehicle Code Section 11-710 requires drivers to follow other vehicles at a reasonable and prudent distance, considering vehicle speed, traffic, and roadway conditions.

However, liability is not automatically established simply because a vehicle was struck from behind. The circumstances of the collision must be investigated. Potentially liable parties may include:

• A negligent driver who was speeding or following too closely.
• A distracted driver who failed to notice stopped traffic.
• An employer whose employee caused a collision while performing job duties.
• A commercial trucking company when negligent operations contributed to the crash.
• A vehicle manufacturer when a defective safety component contributed to the injuries.

What Compensation Can You Recover After a Rear-End Accident?

When another driver’s negligence causes a rear-end collision, injured victims may be entitled to compensation for their economic and non-economic damages. Depending on the circumstances, recoverable damages may include:

Economic damages:

• Emergency room and hospital bills.
• Medical treatment and rehabilitation expenses.
• Prescription medication and medical equipment.
• Future medical expenses.
• Lost wages and employment benefits.
• Reduced future earning capacity.
• Transportation expenses related to medical care.

Non-economic damages:

• Physical pain and suffering.
• Emotional distress.
• Loss of normal life.
• Permanent disfigurement.
• Disability and physical limitations.
• Loss of enjoyment of everyday activities.

The value of a personal injury claim depends on the severity of the injuries, the available insurance coverage, the evidence establishing liability, and the long-term effects of the accident. A settlement offer made shortly after a collision may not account for future medical expenses or permanent complications. Before accepting an insurance settlement, injured individuals should understand the full extent of their injuries and potential financial losses.

Frequently Asked Questions About Rear-End Accident Injuries

What is the most common injury in a rear-end collision?

Whiplash and other neck injuries are among the most frequently associated injuries. The sudden forward-and-backward movement of the head can strain or damage the muscles, ligaments, and other structures in the neck.

Can you suffer serious injuries in a low-speed rear-end accident?

Yes. Even relatively low-speed collisions can cause whiplash, back injuries, herniated discs, and other soft-tissue injuries. Vehicle damage alone does not reliably establish whether someone was injured.

How long after a rear-end accident can symptoms appear?

Some symptoms appear immediately, while others may take hours or several days to develop. Whiplash symptoms, headaches, stiffness, and other soft-tissue complaints may be delayed. Anyone experiencing new symptoms should seek medical evaluation.

Can a rear-end accident cause a herniated disc?

Yes. The forces generated during a collision can injure spinal discs or aggravate an existing condition. A herniated disc may cause neck or back pain, numbness, tingling, and weakness.

Should I go to the doctor after a minor rear-end accident?

Yes. A medical evaluation can identify injuries that may not be immediately apparent. Prompt treatment also creates medical documentation connecting your complaints to the accident.

Can I recover compensation if I was partially at fault?

Potentially. Under Illinois modified comparative negligence law, you may recover compensation if you are not more than 50% responsible for the accident. Your recovery will be reduced by your percentage of fault.

What if the insurance company says my injuries are unrelated to the accident?

Insurance companies sometimes argue that injuries are pre-existing, degenerative, or unrelated to the collision. Medical records, diagnostic imaging, treatment histories, and expert medical opinions can help establish the relationship between the accident and the injuries. An existing medical condition does not automatically prevent someone from pursuing compensation for an injury aggravated by a collision.
