Underride Accidents in South Dakota

Average Settlement: $700,000 – $2,500,000 | Statute of Limitations: 3 years from the date of the accident

Underride Accidents Overview

Underride accidents are among the deadliest types of truck crashes. They occur when a smaller vehicle slides underneath the trailer of a large truck, either from the rear or the side. The trailer can shear off the top of the passenger vehicle at windshield level, causing catastrophic or fatal injuries to occupants. Despite federal requirements for rear underride guards, many trucks lack adequate side guards, and existing guards may not meet the force of real-world crashes. Underride accidents often result in wrongful death claims.
