Sudden Stops
A tractor-trailer stopping abruptly or unexpectedly can create a severe rear-impact hazard for vehicles traveling behind it.
Underride crashes are among the most dangerous commercial-truck collisions because a passenger vehicle can travel beneath the higher structure of a tractor-trailer.
The Piri Law Firm represents people and families throughout Dallas–Fort Worth after catastrophic rear and side underride truck crashes.
An underride accident occurs when a smaller vehicle travels partially or substantially underneath a larger commercial truck or trailer during a collision. These crashes can occur at the rear or side of a trailer and can cause catastrophic head, neck, spinal, and fatal injuries.
An investigation should determine not only why the passenger vehicle contacted the trailer, but also the truck's movement, visibility, lighting, reflective equipment, structural components, and surrounding traffic conditions.
A tractor-trailer stopping abruptly or unexpectedly can create a severe rear-impact hazard for vehicles traveling behind it.
A trailer moving across an occupied lane can place a smaller vehicle beside or beneath the trailer before the motorist can escape.
Darkness, weather, poor lighting, or inadequate conspicuity can make a trailer difficult for approaching motorists to identify.
A long trailer crossing traffic lanes during a turn can create a broad side-impact and underride hazard.
Commercial vehicles stopped on or near a roadway can create serious risks if motorists are not adequately alerted to their presence.
A passenger vehicle may be pushed beneath a trailer by another vehicle during a chain-reaction collision.
The rear or side structure, underride guard, reflective material, lighting, damage patterns, tires, brakes, maintenance history, and other physical evidence may help explain how the collision occurred and the forces involved.
Speed, braking, lane changes, turns, stopping position, visibility, warning measures, and other driver conduct may require investigation.
Investigators may need to examine the trailer structure, guard, lights, reflective material, maintenance, repairs, and collision damage.
Commercial vehicles may contain electronic information relevant to speed, braking, operation, and events immediately surrounding the crash.
The driver, motor carrier, tractor owner, trailer owner, maintenance providers, and other entities may require investigation depending on the facts.
Identifying the entities responsible for the driver, tractor, trailer, maintenance, and operation can be important when investigating a serious underride collision.
Driving decisions involving speed, lane position, turning, braking, visibility, and warning measures may be relevant.
Driver qualification, supervision, scheduling, safety practices, and vehicle operations may require review.
Ownership and control of the tractor and trailer can affect the investigation and available records.
Inspection, repair, lighting, reflective equipment, guard condition, and other maintenance issues may become relevant.
Important evidence can include photographs, measurements, trailer and guard damage, electronic vehicle information, driver records, inspection and maintenance documents, dash-camera footage, surveillance video, witness information, police records, and physical evidence from the roadway.

Explore →A rear underride crash involves a smaller vehicle traveling beneath the rear of a truck or trailer. A side underride crash involves a smaller vehicle traveling beneath or into the side area of a commercial trailer.
Commercial trailers sit significantly higher than many passenger vehicles. In an underride collision, the trailer structure may intrude into areas of the passenger vehicle above the primary front-end crash structures, creating a risk of catastrophic injury.
Potential evidence includes the tractor and trailer, underride guard, lighting and reflective equipment, photographs, measurements, electronic vehicle information, maintenance and inspection records, driver records, video, witness information, and roadway evidence.
Depending on the circumstances, potentially relevant parties may include the commercial driver, motor carrier, tractor or trailer owner, maintenance providers, another motorist, or others whose conduct contributed to the collision.
Texas generally applies a two-year limitations period to personal injury claims, although exceptions can apply. Trucks, trailers, electronic data, video, and other evidence may need to be preserved much sooner.
