Common Causes of Tractor-Trailer Accidents

Understanding Tractor-Trailer Accidents

Tractor-trailer accidents on California highways can change lives in seconds. If you or someone you care about has been hurt in a crash with a big rig, you’re not alone. Accidents involving large trucks often lead to serious injuries, lengthy recovery, or lasting loss. Knowing why these crashes happen is the first step toward protecting your rights and making informed decisions. California’s busy freeways, like I-5 and I-10, see thousands of trucks each day, so understanding the risks helps you stay safer—and helps if you ever need to take legal action.

You can learn more about the broader landscape of traffic accidents in California or explore specifics like car accidents and rideshare accidents to see how truck crashes compare.

Driver Fatigue

Truck drivers often face long hours behind the wheel. Despite federal Hours of Service (HOS) rules that limit driving time, fatigue still plays a major role in many tractor-trailer accidents.

• Long stretches without rest
• Pressure to meet delivery deadlines
• Sleep disorders going untreated

Fatigue can lead to slower reaction times or even falling asleep while driving. For more about the impact of fatigue, see our article on common causes of car accidents.

Distracted Driving

Distractions aren’t just a problem for passenger vehicles. Truck drivers may use smartphones, GPS devices, or even eat while driving. All of these distractions can take attention away from the road.

• Texting or making calls
• Adjusting navigation systems
• Eating or drinking on the go

Learn how distracted driving compares to other dangers in California traffic accidents.

Speeding and Aggressive Driving

Speeding is a leading cause of tractor-trailer crashes. Large trucks need much more distance to stop, especially at high speeds.

• Exceeding posted speed limits
• Ignoring weather or road conditions
• Tailgating or unsafe lane changes

Aggressive driving can also include weaving or failing to yield, which is covered in more detail on our car accident page.

Poor Vehicle Maintenance

A tractor-trailer needs regular upkeep. Faulty brakes, worn tires, or broken lights can quickly turn into major hazards.

• Skipping scheduled repairs
• Driving with worn-out parts
• Failing to check brakes and tires

If you suspect a maintenance issue caused your crash, see defective vehicle parts claims or steps to prove manufacturer liability.

Improper Cargo Loading

The way cargo is loaded can affect a truck’s balance and handling. Loads that are too heavy or unevenly distributed can lead to rollovers or lost cargo.

• Overloaded trailers
• Unsecured cargo
• Shifting loads causing instability

Learn how product liability applies to truck cargo, especially when defective equipment or improper loading is involved.

Driving Under the Influence

Alcohol or drug use behind the wheel is illegal and especially dangerous for truck drivers responsible for massive vehicles.

• Prescription or over-the-counter medication misuse
• Illicit drug use
• Alcohol consumption

California’s strict DUI laws apply to commercial drivers, and violations can mean both criminal and civil liability. Find out more about legal consequences in California accident cases.

Inadequate Training

Operating a tractor-trailer requires specialized skills. Inexperienced or poorly trained drivers are more likely to make critical errors.

• Not understanding truck blind spots
• Failing to perform safety checks
• Improper maneuvering in traffic

Employers have a duty to provide proper training, and failure to do so may lead to liability. The workplace responsibilities section covers more about employer duties in the transportation industry.

Equipment Failure

Sometimes, a crash is caused by a defective part—like a tire blowout or brake failure. In these cases, both the trucking company and the manufacturer might share responsibility.

• Brake malfunction
• Tire blowouts
• Steering or transmission problems

Explore defective vehicle parts and product liability if you believe equipment failure played a role in your accident.

Unsafe Road Conditions

Even the best drivers can struggle with unexpected hazards like potholes, debris, or poor signage. Road maintenance issues can contribute to tractor-trailer accidents.

• Construction zones without proper warnings
• Slippery surfaces from rain or spills
• Debris left in truck lanes

You can learn more about how premises liability and slip and fall principles can sometimes apply in roadway cases.

Weather Hazards

California is known for sunshine, but fog, rain, and wind can create sudden dangers for trucks. Adapting to changing weather is essential for safe driving.

• Reduced visibility from fog or heavy rain
• Hydroplaning in wet conditions
• High winds affecting trailer stability

For additional safety strategies, review our guide on avoiding dangerous intersections.

Blind Spots and Wide Turns

Big rigs have large blind spots, making it hard to see cars or motorcycles alongside them. Wide turns can trap unsuspecting vehicles.

• “No Zone” blind spots on all sides
• Needing extra space to turn safely
• Risks for nearby pedestrians and cyclists

See how bicycle accidents and pedestrian accidents often intersect with truck crash risks.

Regulatory Violations

Trucking companies and drivers must follow both state and federal rules set by agencies like the California Department of Transportation and Federal Motor Carrier Safety Administration. Violations increase crash risk.

• Ignoring hours-of-service limits
• Skipping required inspections
• Falsifying driving logs

If you believe a regulatory violation contributed to your crash, our steps for proving trucking company liability can help guide your next steps.
