Freeway truck accidents can unfold in seconds, but their consequences often last for years. On major California routes like the I-405 near Sunset Boulevard or the I-5 through Downtown Los Angeles, high speeds and heavy commercial vehicles create a dangerous mix.
When a crash happens, victims are often left with serious injuries, mounting medical bills, and unanswered questions about fault. Understanding why these crashes occur—and how California law applies—can help injured people regain a sense of control.
Here, we break down the most common causes and what steps may help protect your recovery.
Why Freeways Create Unique Risks for Truck Accidents
Freeways are designed for speed and volume, not sudden stops or unexpected hazards. Large trucks require more time and distance to react, especially during congestion near busy interchanges or construction zones.
According to SafeTREC data, speeding remains a significant factor in fatal crashes nationwide. In 2023, more than 11,000 people lost their lives in crashes linked to excessive speed, highlighting how dangerous high-speed conditions can be when combined with large commercial vehicles.
High-Speed Driving and Reduced Stopping Distance
At freeway speeds, even a brief delay can turn deadly. A high-speed collision involving a fully loaded truck leaves little margin for error.
Factors that worsen stopping distance include:
- Vehicle weight and momentum
- Road conditions and traffic flow
- Sudden hazards, such as a disabled vehicle
A single moment of inattention can push a passenger car into a concrete barrier or cause a rear-end impact with the back of the truck.
Unsafe Lane Changes and Blind Spot Issues
Trucks have large blind spots on all sides. Unsafe lane changes are especially dangerous near crowded Los Angeles corridors.
For example, when a Chevrolet truck or passenger car lingers in a truck’s blind spot, the risk of sideswipe collisions increases. These crashes often require a detailed collision investigation to determine whether proper signaling and spacing were used.
Truck Driver Fatigue on Long Freeway Routes
Long hauls across California can strain even experienced drivers. Fatigue reduces reaction time and decision-making ability, particularly during overnight or early-morning hours.
While regulations require rest periods, fatigue can still occur due to:
- Tight delivery schedules
- Undiagnosed medical condition
- Inadequate rest between shifts
Post-crash health checks and driver logs are often reviewed during a crash report to assess compliance.
Brake Failures and Mechanical Issues at Highway Speeds
Mechanical failures become far more dangerous at freeway speeds. A tire blowout or a brake malfunction can cause a truck to suddenly veer across lanes.
Maintenance issues may involve:
- Worn braking systems
- Poor inspection practices
- Fleet vehicles, including a Caltrans truck, operating under demanding conditions
Inspection records and maintenance logs often play a key role in determining liability.
Improperly Loaded or Shifting Cargo
Cargo that is unevenly loaded or unsecured can shift during transit, destabilizing the truck. This increases rollover risk and reduces steering control, especially on curves or sudden stops.
Improper loading can also worsen injuries in a crash, leading to outcomes such as catastrophic injury, traumatic brain injury, spinal cord injury, or even third-degree burns. In such cases, liability might extend beyond the driver to include freight handlers or loading companies that failed to adhere to safety standards.

Frequently Asked Questions
Responsibility may involve more than just the driver. Liability may extend to the trucking company for hiring or supervision issues, maintenance providers for failures, or cargo loaders if improper loading caused the crash. Each party’s role is assessed based on evidence and safety rules.
A sudden emergency defense does not automatically eliminate liability. Investigators analyze vehicle data, traffic, and driver actions before the crash to determine whether the crash was unavoidable or whether earlier choices, such as speed or following distance, contributed to it.
In most cases, California law allows a personal injury claim to be filed within 2 years of the crash. However, if a government vehicle or roadway condition is involved, notice deadlines may be shorter, making early legal review essential.
Not always. Some injuries, including traumatic brain injury or internal trauma, may develop or worsen hours or days after the initial event. Delayed symptoms can affect both medical treatment and insurance claims, which is why prompt evaluation and documentation are strongly recommended.
