Why Are Traumatic Brain Injuries Common after Truck Crashes?

Legally Reviewed by Scott Sobol on July 31, 2026

Traumatic brain injuries (TBIs) are common after truck crashes because the size and weight difference between a commercial truck and a passenger vehicle produces far more forceful jolts, impacts, and secondary collisions than a typical car accident. Motor vehicle crashes are consistently one of the leading causes of TBI-related hospitalizations in the United States, and the violent forces involved in a truck collision make head and brain injuries especially likely.

Any traumatic brain injury, whether it is classified as mild, moderate, or severe, needs to be treated seriously and promptly. If you or a family member sustained a TBI after a truck crash, The Law Offices of Scott Sobol can help you understand your medical documentation needs and legal options while you focus on recovery.

Symptoms Associated with TBIs After Truck Accidents

Brain injuries can occur during a truck crash because of the direct blow or sudden deceleration experienced during the incident. The severity of a TBI resulting from a truck accident depends on the type, intensity, and duration of the impact. Injuries to the brain are generally classified as mild, moderate, or severe, and can be further grouped by which area of the brain is affected. When confined to a specific region, they are known as focal injuries; when spread across wider areas, they are known as diffuse injuries.

Depending on the type of TBI, a truck accident victim can experience a range of symptoms. These can vary widely from injury to injury, but victims may generally experience the following:

• Headaches that persist or worsen over time
• Nausea and vomiting in the hours after the crash
• Dizziness or loss of coordination affecting balance
• Blurred vision or ringing in the ears
• Fatigue that does not improve with rest
• Mood changes, confusion, or memory difficulty

Some brain injuries can also bring on emotional changes, decreased concentration, and other cognitive effects following the accident. Because these symptoms overlap with general shock or stress after a crash, it can be easy to dismiss them at first.

Why Truck Accidents Are Especially Likely to Cause TBIs

When large commercial trucks are involved in a collision, the size and weight of the vehicle typically results in more severe injuries to the occupants of other vehicles than a crash between two passenger cars would. According to the Centers for Disease Control and Prevention, motor vehicle crashes remain one of the leading causes of TBI-related hospitalization nationwide, and the forces involved in truck collisions, sudden stops, rollovers, and underride impacts, make brain injuries especially common in this category of crash.

Brain injuries are complex from both a legal and medical standpoint because a TBI can involve a secondary injury: damage to the brain that becomes apparent only after the initial event. Secondary brain injury can develop 12 to 24 hours after the initial impact and may take weeks or months to fully present. Because of this delayed timeline, it is important to seek medical evaluation promptly after any truck accident, even if you feel fine initially.

Types of TBIs Associated with Truck Accidents

TBIs typically occur in a truck accident because of the jarring, violent movement involved in the collision. This type of incident can cause your head to strike an object inside the vehicle or cause your head and neck to jolt suddenly, even without direct contact.

The following are among the most common TBI classifications associated with a collision involving a large commercial truck:

Concussion

A concussion is the mildest and most common form of TBI. Symptoms can include headache, confusion, and temporary memory problems, and most people recover with rest and monitoring, though some concussions can have lasting effects.

Contusion

A contusion is bruising of the brain tissue itself, often at the point of impact. Depending on size and location, a contusion may require close medical monitoring or, in more serious cases, surgical intervention.

Diffuse Axonal Injury

This type of injury occurs when the brain twists or shifts rapidly inside the skull, tearing nerve fibers across a wide area. Diffuse axonal injuries are frequently associated with high-speed truck collisions and can range from moderate to severe.

Coup-Contrecoup Injury

A coup-contrecoup injury happens when the brain is struck at the point of impact and then rebounds to strike the opposite side of the skull, producing damage in two separate locations.

Following a crash with a large commercial truck, seek urgent medical attention regardless of how you feel immediately afterward. Prompt medical treatment and documentation of your symptoms can matter later if you pursue a claim for your injuries. For a closer look at how these injuries are also evaluated after passenger vehicle collisions, see our related post on whether a traumatic brain injury can occur after a Florida car accident.

Leading Causes of Truck Accidents

Various factors can lead to a truck accident. Although you may be careful and attentive on the road, the actions of other drivers, mechanical issues, and company practices can all contribute to a dangerous incident. Leading causes of truck accidents include the following:

• Fatigued or distracted commercial drivers
• Trucking company scheduling and maintenance practices
• Truck and trailer equipment defects
• Improperly secured or overloaded cargo
• Actions of other drivers sharing the road with the truck

If you suspect any of these factors contributed to your truck accident injuries, a thorough review of your case can help determine what happened and what your legal options may be. Our page on Florida truck accident claims covers how liability is typically evaluated in these cases.

Documenting a TBI for a Truck Accident Claim

Because some TBI symptoms take time to appear, ongoing documentation matters. Follow-up appointments, neurological evaluations, and imaging studies can help create a clear medical record connecting your symptoms to the crash. Keeping a personal log of how your symptoms change day to day can also support a more complete picture of how the injury has affected your daily life. If a loved one’s brain injury has affected their ability to communicate, a family member or caregiver may need to help manage this documentation on their behalf.
