Get the legal support you need from a trusted Texas truck accident attorney
Most people have never heard of an underride accident. But for the families who have lost loved ones in these crashes, the words are unforgettable. These accidents are among the most devastating on the road, often turning what would have been a survivable collision into an instant fatality.
Imagine a car rear-ending a tractor-trailer. You’d expect crumpled fenders and some bruises. But when a car strikes a truck in the right conditions, it doesn’t just crumple; it slips beneath the trailer like a coin sliding under a door. In the blink of an eye, the entire top of the vehicle can be sheared off, leaving the occupants with no chance.
What is an underride accident?
An underride accident happens when a smaller passenger vehicle slides underneath the body of a large commercial truck or trailer during a crash. Instead of the front bumper absorbing the blow, the vehicle passes under the truck’s elevated frame, causing the trailer to intrude into the cabin area.
There are two primary types: rear underride and side underride. Rear underride accidents usually happen when a truck brakes suddenly or is stopped on the side of the road, and a vehicle behind it cannot stop in time. Side underride crashes occur when a truck is making a turn or crossing traffic, and a car hits the side of the trailer with force.
Why are these crashes so often fatal?
In a typical car accident, a vehicle’s crumple zones absorb much of the impact, airbags deploy, and seatbelts restrain passengers. These safety systems save lives. But in an underride crash, the front of the car is bypassed. The lower edge of the trailer slices through the windshield and into the space where people sit.
Because the point of impact is so high, airbags may not deploy at all. Roofs collapse and the structure that protects your head and chest is instantly compromised. The injuries are brutal. They can result in traumatic brain injuries, spinal cord damage, and often decapitation.
Even at relatively low speeds, the outcome is often fatal. Emergency crews who arrive at the scene of an underride accident often find that there is nothing they can do. The passenger compartment is gone, and the people inside didn’t have a chance.
How common are underride accidents?
Official numbers are hard to come by, but it’s estimated that hundreds of people are killed in underride crashes each year in the United States, and the actual number might be higher. That’s because these accidents are often misclassified in police reports or not labeled specifically as underride crashes.
Many happen late at night or in low-visibility conditions. In some cases, cars rear-end trucks that are parked without proper lighting or reflective materials. In others, trucks cross intersections or turn in front of oncoming traffic.
What typically causes an underride crash?
There is rarely just one reason. These collisions usually happen because of a perfect storm of poor visibility, driver error, and equipment failure.
A common scenario is a truck that stops too quickly, giving the driver behind little time to react. If that truck has no rear underride guard, or if the guard is too weak or poorly maintained, the following vehicle can slide beneath it with deadly results.
In other cases, trucks are parked on the side of the road with no hazard lights, reflectors, or cones. Drivers coming around a bend at night or in fog may not see them until it's too late. Sometimes, truck drivers make wide left-hand turns or try to cross a busy road, which exposes the entire side of their trailer to oncoming traffic. If that trailer doesn’t have a side guard, a car can strike it and disappear beneath very quickly.
What types of trucks are involved in these accidents?
Almost any large truck with high ground clearance can be involved in an underride crash, including:
- 18-wheelers: These standard big rigs are often involved in severe underride collisions.
- Flatbed trucks: These trucks are especially dangerous when their beds are empty, which makes them sit higher and harder to see at night.
- Dump trucks and garbage trucks: The height and weight of these trucks make rear underride accidents particularly deadly.
- Delivery trucks: These often operate in neighborhoods and commercial areas where visibility is limited.
- Box trucks: Box trucks are common in urban areas. They pose a high risk when making sharp turns or blocking lanes, especially around cars, bicycles, and pedestrians.
Can underride guards actually prevent these crashes?
Rear underride guards are steel bars mounted beneath the trailer to stop a car from sliding underneath. When they are properly designed and maintained, these guards can absorb impact and prevent a fatal intrusion into the cabin.
However, not all guards are created equal. Many of the ones on the road today were built to outdated standards and fail in crash tests above 35 miles per hour. Additionally, many trucks lack side underride guards entirely, even though they are proven to be just as important.
These guards are not yet required by federal law in the United States. For now, installing them is mostly left up to the discretion of trucking companies.
Are there laws being proposed to improve safety?
For years, safety advocates and grieving families have been pushing for stricter regulations. One of the most prominent proposals is the Stop Underrides Act, which has been introduced multiple times in Congress.
If passed, the law would require all new trailers to be equipped with both rear and side underride guards that meet modern safety standards. It would also introduce stronger inspection requirements and give regulators more authority to hold violators accountable.
Despite strong support from the public and several lawmakers on both sides of the aisle, the bill has repeatedly stalled due to lobbying from the trucking industry, which argues that the cost of retrofitting vehicles and the added weight would hurt small carriers.
What should someone do after an underride crash?
If you or someone you love is involved in an underride accident, getting medical attention is the top priority. Even if you think your injuries are minor, you may have internal trauma that isn’t immediately obvious.
Next, if you are able, take photos of the scene. Capture the position of the vehicles, the condition of the truck’s underride guard, road markings, skid marks, and any lighting on the truck. Try to get names and numbers of witnesses and preserve as much evidence as possible.
As soon as possible, contact a Texas attorney who understands underride crashes. These cases are often complicated, and evidence can disappear quickly. Trucking companies often have legal teams that start working to protect their interests immediately. You’ll need someone on your side who can gather maintenance records, obtain black box data, and fight to hold the right parties accountable.
Who can be held responsible for these crashes?
Multiple parties may be liable. In some cases, the truck driver may have made a dangerous maneuver, parked illegally, or failed to use warning lights. In others, the trucking company may be responsible for failing to maintain or install underride guards. The manufacturer of the trailer could also be at fault if the guard was defective or missing altogether.
If a third-party maintenance company worked on the truck, and failed to address safety issues, they could also share blame.
