When a passenger vehicle collides with a commercial truck, the results can be devastating. Underride and override crashes are among the deadliest types of truck accidents, often causing catastrophic injuries or fatalities. Here’s what you need to know about these dangerous collisions and your legal rights.
What Are Underride and Override Truck Accidents?
Not all truck accidents are the same. Two of the most severe types are underride and override crashes. These collisions occur because of the significant size and height difference between commercial trucks and passenger vehicles, allowing the truck to bypass many of a car’s built-in safety features. As a result, victims often suffer traumatic brain injuries, spinal cord injuries, severe neck injuries, or even death.
If you or a loved one has been injured in one of these accidents, understanding how they happen can help you protect your legal rights.
What Is an Underride Truck Accident?
An underride accident occurs when a smaller vehicle slides underneath the rear or side of a commercial truck or trailer.
Unlike a typical collision where the vehicle’s bumper and crumple zones absorb much of the impact, an underride crash allows the trailer to intrude directly into the passenger compartment. This makes these accidents especially deadly because the occupants’ heads, necks, and upper bodies are often exposed to the full force of the collision.
What Is an Override Truck Accident?
An override accident happens when a large commercial truck rides over the top of a smaller passenger vehicle, usually during a rear-end collision.
Because of the truck’s tremendous weight and height, the smaller vehicle can become crushed beneath the truck’s front end, resulting in catastrophic injuries and significant vehicle damage.
Why Are Underride and Override Accidents So Dangerous?
Passenger vehicles are designed to protect occupants during collisions with other passenger vehicles—not 80,000-pound tractor-trailers.
In underride crashes, the car’s airbags and crumple zones may provide little protection because the vehicle slides beneath the trailer instead of absorbing the impact through its front end.
Override crashes can be just as devastating because the truck’s massive weight may collapse the roof and passenger compartment of the smaller vehicle.
These crashes frequently result in:
- Traumatic brain injuries (TBI)
- Spinal cord injuries
- Neck and back injuries
- Severe facial injuries
- Internal organ damage
- Crush injuries
- Wrongful death
Common Types of Underride and Override Crashes
Rear Underride Accidents
A rear underride accident occurs when a passenger vehicle crashes into the back of a truck or trailer and slides underneath it.
These crashes often happen because of:
- Sudden stops
- Poor visibility
- Inadequate lighting
- Heavy traffic
- Weak or damaged rear underride guards
Side Underride Accidents
A side underride collision happens when a passenger vehicle strikes the side of a trailer crossing an intersection or making a turn.
These accidents are especially dangerous at night or in low-visibility conditions because trailers can be difficult to see across roadways. Unlike rear guards, side underride guards are not uniformly required under federal regulations.
Override Accidents
Override crashes typically occur when a commercial truck rear-ends a smaller vehicle.
Common contributing factors include:
- Speeding
- Distracted driving
- Driver fatigue
- Brake failure
- Poor maintenance
- Following too closely
What Safety Equipment Helps Prevent Underride Crashes?
Federal regulations require many commercial trailers to be equipped with rear impact guards, commonly called underride guards.
These guards are designed to prevent passenger vehicles from sliding underneath the trailer during rear-end collisions. Federal Motor Vehicle Safety Standards (FMVSS) 223 and 224 establish requirements for the design and performance of many rear impact guards, and recent updates have strengthened these standards.
However, not every trailer is subject to the same requirements, and side underride protection remains an ongoing safety concern.
Who Can Be Held Responsible?
Truck accident cases often involve multiple potentially liable parties.
Depending on the circumstances, responsibility may fall on:
- The truck driver
- The trucking company
- The trailer owner
- A maintenance company
- The trailer or guard manufacturer
- Cargo loading companies
- Other negligent drivers
An experienced truck accident attorney can investigate the accident and identify every available source of compensation.
What Compensation Can Victims Recover?
If someone else’s negligence caused your truck accident, you may be entitled to compensation for:
- Medical expenses
- Future medical treatment
- Lost wages
- Loss of future earning capacity
- Pain and suffering
- Emotional distress
- Permanent disability
- Disfigurement
- Property damage
- Wrongful death damages for surviving family members
The amount of compensation depends on the severity of your injuries and the facts of your case.
What Should You Do After an Underride or Override Accident?
If you’re involved in a truck accident:
- Call 911 immediately.
- Seek medical attention, even if your injuries seem minor.
- Take photos of the accident scene if you’re able.
- Gather contact information from witnesses.
- Avoid giving recorded statements to insurance companies before speaking with an attorney.
- Contact an experienced truck accident lawyer as soon as possible.
Early action can help preserve critical evidence such as truck maintenance records, electronic logging data, and surveillance footage.
Why Truck Accident Cases Are More Complex
Unlike ordinary car accidents, truck accident claims often involve:
- Federal trucking regulations
- Multiple insurance policies
- Commercial vehicle inspections
- Driver qualification files
- Black box (ECM) data
- Maintenance records
- Corporate trucking companies
These factors make truck accident litigation significantly more complex than most motor vehicle cases.
