2 Injured After Semitruck Jackknifes in Osceola County on I-4 Eastbound

A major crash involving a semitruck shut down eastbound Interstate 4 in Osceola County on Sunday night, causing significant delays and prompting a full emergency response. According to the Florida Highway Patrol, the collision occurred just before 9:30 p.m. near Mile Marker 62, close to World Drive and the entrance routes to Disney-area attractions.

Officials say the crash involved:

• A semitruck whose trailer jackknifed, swinging sharply and folding toward the cab
• The trailer subsequently colliding with the concrete inside shoulder wall
• A second vehicle striking the wall as a result of the semitruck’s loss of control

All eastbound lanes were shut down as emergency crews worked to secure the scene. Portions of the westbound lanes were also blocked due to lane closures on the inside and inside-center lanes for both directions.

The semitruck remained immobilized on the interstate for hours as officials coordinated cleanup and investigative efforts.

According to FHP:

• The driver of the semitruck was not injured
• The driver and passenger of the second vehicle were transported to AdventHealth Celebration with reportedly minor injuries

FHP troopers say they are still gathering details. The investigation is ongoing.

A jackknifed trailer can instantly create a multi-vehicle collision hazard, especially on a busy interstate like I-4. When a trailer swings out of alignment:

• The truck may lose all directional control
• Surrounding drivers have little to no time to react
• Lanes can become blocked in both directions
• Secondary impacts—such as hitting a median wall—are common

Jackknifing can be caused by factors such as:

• Sudden braking
• Speeding or improper speed for road conditions
• Wet or slippery pavement
• Overcorrection or steering errors
• Mechanical failure or load imbalance
• Driver fatigue or distraction

Determining what caused the jackknife is critical to assessing liability.

Legal Considerations for Victims of a Jackknife Crash

Even when injuries appear minor, victims should understand their rights. Crashes involving commercial vehicles are governed by extensive state and federal trucking regulations, and numerous parties may be liable.

Potential responsible parties include:

1. The Truck Driver

Liability may apply if the driver:

• Was speeding or tailgating
• Braked improperly
• Failed to maintain lane
• Was distracted or fatigued

2. The Trucking Company

Claims may arise if the company:

• Failed to maintain the truck
• Allowed unsafe loading or weight imbalance
• Pressured drivers to rush schedules
• Neglected required inspections

3. Maintenance Contractors or Loaders

If mechanical issues or improperly secured cargo contributed to the loss of control.

4. Vehicle or Tire Manufacturers

In cases involving equipment failure.

Because trucking companies act immediately to limit their liability after a crash, victims need swift legal support to preserve:

• Black box data
• Dash cam footage
• Driver logs
• Maintenance and inspection records
• Crash scene evidence
