Underride Accident Attorneys

A passenger car’s front end sits roughly 30 inches off the ground. The bottom of a trailer often sits 45 inches up or higher.

That gap is exactly why underride crashes are among the deadliest collisions on the road, and why federal regulators have spent years trying, with mixed success, to close it.

The Voorhies Law Firm represents families affected by these crashes.

What Is an Underride Accident Claim?

An underride accident occurs when a passenger vehicle collides with the rear or side of a truck trailer and slides underneath it, rather than the two vehicles’ crashing or meeting head-on.

This is uniquely dangerous because:

  • The car’s airbags, crumple zones, and other safety systems are built to protect against impacts at bumper height, not against sliding beneath a trailer
  • The point of impact often shifts to the windshield and roof, directly in line with occupants’ heads
  • In severe cases, the trailer can shear off the top of the car entirely
  • These crashes are frequently fatal even at relatively low speeds

Because the height mismatch between a car and a trailer is the whole problem, underride guards, and whether they were present, adequate, and functioning, are often the central issue in these cases.

How Louisiana Law Applies

Underride cases sit at the intersection of a specific federal safety standard and ordinary negligence law, and the regulatory history here matters.

Rear Impact Guard Standards (FMVSS 223 and 224)

Federal law requires trailers and semitrailers to have rear impact guards designed to prevent underride.

In 2022, following a mandate in the Bipartisan Infrastructure Law, federal regulators strengthened these standards, requiring guards to withstand a 35 mph impact, up from the previous 30 mph benchmark, effective for new trailers starting in January 2023.

Whether a guard met this standard, or was missing, damaged, or improperly maintained, is often central to an underride case.

Side Underride Guards Are Not Yet Required

Unlike rear guards, side underride guards are not currently mandated by federal law, despite years of advocacy and a federal advisory committee’s recommendation that they be required.

A crash involving side underride, rather than rear underride, may turn more heavily on ordinary negligence and product liability theories, since no specific federal equipment standard currently applies.

Multiple Potentially Responsible Parties

An underride case can involve the truck driver, the carrier, and, if the guard itself failed or was defectively designed, the trailer manufacturer under Louisiana’s product liability framework. Comparative fault under Civil Code article 2323 and the two-year filing deadline under article 3493.1 apply as they do to other truck accident claims.

Frequently Asked Questions

Federal law has required rear impact guards on trailers since the 1990s, with strengthened standards taking effect for new trailers in January 2023. Whether the specific trailer involved complied with the applicable standard, and whether the guard functioned properly, is a central question in these cases.

Side underride guards aren’t currently required by federal law, even though safety advocates have pushed for them for years. A side underride case may rely more heavily on ordinary negligence and, if the guard itself was defective, product liability theories.

Potentially, if the underride guard was defectively designed or manufactured, in addition to any claims against the driver or carrier.

Under article 3493.1, the general deadline is two years from the crash date for incidents on or after July 1, 2024.
