Jackknife Accidents in Pennsylvania
Average Settlement: $500,000 – $1,800,000 | Statute of Limitations: 2 years from the date of the accident
Jackknife Accidents Overview
A jackknife accident occurs when a truck's trailer swings outward and forms a 90-degree angle with the cab, resembling a folding knife. These accidents are among the most dangerous truck collisions because the trailer can sweep across multiple lanes of traffic, striking other vehicles and creating chain-reaction crashes. Jackknife accidents are frequently caused by sudden braking, slippery road conditions, improper loading, or equipment failure. The driver may lose all control of the vehicle, and the massive trailer can block entire highways.
