A truck underride accident happens when a car slides under the trailer of a big truck during a crash. The car’s roof can be torn off in seconds. The people inside can be crushed, and many do not survive. It is one of the most severe types of truck accidents on Louisiana roads, and most families have never heard the word “underride” until it happens to someone they love.
How a Truck Underride Accident Happens
An underride crash can happen at the back, the side, or the front of a trailer.
- Rear underride happens when a car hits the back of a trailer, often because the truck stopped fast or was parked without enough warning lights.
- Side underride happens when a car slides into the long open space under the middle of a trailer, usually when the truck is turning or crossing a road.
- Front override happens when a truck rear-ends a smaller car and rides up over it instead of stopping.
Dark roads, sudden braking, wide turns, and blind spots all raise the risk. Louisiana has miles of rural highway and busy interstate corridors, which makes these crashes a real danger for families driving through Baton Rouge and the surrounding parishes.
Do Trucks Have to Have Underride Guards?
Federal law requires most large trailers to have a rear underride guard. The rule says the guard cannot sit more than 22 inches off the ground, and it must stay close to the width and back edge of the trailer. In 2022, the rule got stronger. New guards must now hold up when a car hits the trailer at 35 miles per hour.
Side guards are different. Federal law does not yet require every trailer to have one, even though safety researchers believe side guards could save many lives each year. Safety advocates have asked regulators to close this gap, and the issue is still being studied.
Why a Guard That Passes the Test Does Not Always Stop the Crash
Passing the federal test is not the same as being crash safe. Research shows that some guards which technically pass the test still fail and let a car slide underneath in a real crash. That gap between passing the rule and truly protecting you is part of why these crashes still happen, even on well regulated highways. You can read more on the Insurance Institute for Highway Safety’s underride research page.
The Injuries an Underride Crash Can Cause
Underride crashes tend to cause some of the most serious injuries I see in my office. Because the guard or the trailer strikes the passenger compartment directly, victims often suffer severe head injuries, spinal cord damage, or worse. Families are often left with medical bills, lost income, and grief on top of the shock of the crash itself. These are not simple fender benders, and they should never be treated like one.
What To Do After a Truck Underride Accident in Baton Rouge
If you or someone you love is ever in this kind of crash in East Baton Rouge Parish, St. George Parish, or Ascension Parish, a few steps matter right away.
- Call 911 and get medical help, even if you feel okay at first.
- Take photos of the trailer, the guard, and the scene if you can safely do so.
- Get the names of any witnesses.
- Avoid giving a recorded statement to the trucking company’s insurer before you talk to a lawyer.
- Reach out to an attorney early, since evidence like black box data and dashcam footage can disappear fast.
In Louisiana, you generally have two years from the date of the crash to file a claim, so time matters more than most people realize.
