When a passenger vehicle becomes wedged under the rear of an 18-wheeler, the immediate question isn’t just whether the driver of the smaller vehicle was at fault—it’s whether the truck presented an avoidable hazard in the first place. Rear-end underride collisions are some of the most deadly and damaging types of crashes, and the law recognizes that both drivers and trucking companies share responsibility for preventing them.

At 5:30 in the morning, lighting conditions may have been poor, especially at an intersection where movement from stoplights or turns can create unexpected changes in traffic flow. If the truck was stopped or moving slowly, it’s important to determine whether it had reflective markings, functional taillights, and a federally required underride guard—designed specifically to keep a smaller vehicle from sliding beneath the trailer. If any of those elements were missing, damaged, or obscured, it could mean the rear of the truck was not reasonably visible or protected.

It also matters whether the truck was legally and properly positioned. If it had just pulled onto the roadway or was stopped unexpectedly, investigators will want to know whether the maneuver followed traffic laws, used appropriate signaling, and gave other drivers enough time to react. In past cases I’ve worked on, trucks that appeared stationary had actually moved into traffic moments before impact—leaving little or no opportunity for the other driver to avoid a collision.

The trucking company’s role will also come under scrutiny. Carriers are required to maintain their vehicles in road-safe condition, which includes rear lights, reflective tape, and underride protection. If the truck’s visibility equipment was defective or hadn’t been inspected, that could establish a separate layer of liability beyond the driver’s conduct alone.

Key Takeaways:

• Rear-end underride collisions raise serious questions about the truck’s visibility, lighting, and use of underride protection.
• Early morning conditions may have contributed to low visibility, increasing the importance of proper truck lighting and markings.
• Investigators will examine whether the truck was legally stopped, moving, or merging—and whether it gave other drivers enough time to react.
• The trucking company may be liable if the vehicle lacked required safety features or failed inspection standards.
• Determining fault will require close analysis of dash cam footage, ECM data, trailer condition, and roadway layout at the time of the crash.
