Fairfield Jackknife Accident Traps One Person in Car

Person Trapped in Vehicle Involving Fairfield Jackknife Accident on I-680

A Fairfield jackknife accident involving a semi-truck and another vehicle left one person trapped recently and forced a full closure of the I-680 South ramp after I-80 West on Wednesday night. According to the California Highway Patrol (CHP), the crash happened at around 8:26 p.m. One vehicle was found on its side with occupants trapped, while a semi-truck had jackknifed across both lanes, blocking traffic. 

Fairfield Jackknife Accident Causes Shutdown of Southbound Highway

CHP quickly responded to the scene and initiated a full shutdown of the I-680 South ramp. Firefighters and medical crews faced significant delays reaching the scene at 8:34 p.m., as traffic congestion and drivers not yielding to emergency vehicles slowed their progress. To ensure medical access, CHP directed an ambulance to travel the wrong way on I-680 South to reach injured individuals more quickly. 

Investigation Will Determine Cause of Fairfield Jackknife Accident

Crews officially arrived on scene by 8:40 p.m. to begin rescue and medical operations. The CHP traffic crash unit is investigating the cause of the collision and the circumstances leading up to the semi-truck jackknife. All lanes remained closed while emergency responders managed the scene and assisted those involved.

Causes of a Jackknifed Big Rig

A jackknifed big rig usually results from a combination of driver actions, vehicle conditions, and environmental factors.

Common Causes

• Improper or sudden braking: If a truck driver brakes too hard or suddenly, especially on slippery roads or around curves, the trailer can swing out, causing a jackknife.
• Speeding: Driving too fast, especially around ramps or curves, reduces reaction time and makes jackknifing more likely.
• Weather conditions: Rain, ice, and snow decrease traction, raising the risk of a jackknife accident.
• Imbalanced or overloaded cargo: Unevenly distributed or overloaded cargo can destabilize the trailer and lead to loss of control.
• Mechanical defects: Faulty brakes, worn tires, or failure in systems like ABS can trigger jackknifing if the truck loses control during braking.
• Driver error and fatigue: Distracted, fatigued, or inexperienced operators may misjudge maneuvers, brake too hard, or fail to adjust to changing conditions, thereby increasing the risk of a Fairfield jackknife accident.

Additional Contributing Factors

• Sharp turns or evasive maneuvers
• Poor road conditions, including debris
• Sudden swerving to avoid obstacles
• Inadequate maintenance: Regular inspection and proper care reduce preventable risks.
