Settlement Tips

Underride Accidents: Why They're Deadly and Who Pays

7 min read May 17, 2026

Underride Accidents and Liability

An underride accident occurs when a smaller vehicle passes underneath a truck trailer, typically shearing off the roof. These accidents are almost always fatal or catastrophically injurious.

Types of Underride Accidents

Rear underride: Vehicle slides under the back of a trailer
Side underride: Vehicle collides with the trailer side
Frontal underride: Rare but devastating head-on underrides

Preventing Underride Accidents

Federal law requires trucks to have:

Rear underride guards (49 CFR 393.86)
Side guards on certain trailers
Adequate lighting and reflective markings

Liability and Compensation

When underride accidents occur, carriers are typically liable for:

Failure to maintain guards
Failure to maintain adequate lighting
Failure to maintain adequate warnings
Failure to train drivers on safety

Underide accident settlements are among the highest because of the severity of injuries and clear carrier negligence.
