Truck accidents are a serious road safety issue in the USA. Commercial trucks, tractor-trailers, semi-trucks, and 18-wheelers are much heavier and larger than passenger vehicles. Therefore, when a large truck collides with a car, SUV, motorcycle, or other vehicle, the consequences of the crash can be very serious.Truck accidents aren't always caused by a single driver error.
Sometimes driver fatigue is involved; other times, speeding, distracted driving, alcohol or drug impairment, improper cargo loading, mechanical failure, poor maintenance, blind spots, or inadequate training can be factors. Also discusses the different contributing factors of truck crashes. After a commercial truck accident, it's not enough to simply look at how the collision occurred.
The investigation may also include determining what happened before the accident, the driver's condition, whether the truck was properly maintained, whether the cargo was correctly secured, and whether the trucking company followed required safety practices.
1. Driver Fatigue and Drowsy Driving
Driver fatigue is a common cause of truck accidents. Long-haul truck drivers sometimes travel hundreds or thousands of miles. Long routes, night driving, irregular schedules, and insufficient rest can reduce a driver's alertness. When a driver is tired, their reaction time can slow down. It may take additional time for the driver to identify road signs, traffic changes, stopped vehicles, and unexpected hazards.
In severe fatigue, a driver may unintentionally fall asleep for a few seconds. At highway speeds, a vehicle can cover considerable distance in a few seconds. If the driver is not properly monitoring the road during this time, the risk of a collision may increase.
How Fatigue Can Affect Truck Drivers
Fatigue can affect different driver abilities:
- Reaction time
- Concentration
- Decision-making
- Lane control
- Hazard recognition
- Speed management
- Emergency response
A tired driver may feel fully alert when, in fact, their performance may already be affected.
Dispatch Pressure and Fatigue
Sometimes delivery deadlines can also become part of the investigation. For example, if a driver was given an unrealistic delivery schedule and had to take insufficient rest to reach the destination on time, dispatch records and company communications could potentially become relevant evidence.
2. Distracted Truck Driving
Distracted driving can also be a significant cause of commercial truck crashes. Truck drivers must constantly monitor the road, mirrors, surrounding vehicles, and traffic conditions. If the driver takes their attention off the road for even a few seconds, the traffic situation can change quickly. Common distractions can include mobile phone use, texting, adjusting GPS or navigation systems, eating or drinking, using in-cab devices, looking at paperwork, and conversations.
Investigations may attempt to determine, through available evidence, whether distractions were part of the driver's actions before the accident.
- Text messaging
- Phone calls
- Using GPS
- Eating
- Drinking
- Adjusting dashboard controls
- Looking at paperwork
- Looking away from traffic
- Using electronic devicesSentry Insurance discusses cellphone use, eating, drinking, and GPS adjustments as examples of driving distractions. Sentry Insurance
Why Is Distracted Driving Dangerous for Trucks?
Significant distance may be required for a commercial truck to stop in an emergency. Imagine a truck is traveling on a highway and the driver looks at a phone screen for a few seconds. During this duration, traffic ahead suddenly slows down. By the time the driver looks back at the road, the available stopping distance has significantly decreased.
Even if the driver applies emergency braking in this situation, it can be difficult to bring the truck to a complete stop.
Evidence That May Help Investigate Distraction
After a serious crash, investigators could potentially review:
- Cellphone records
- Dashcam footage
- Driver statements
- Witness statements
- Electronic vehicle data
- GPS information
- Company communication records review the following:
The same evidence is not available in every case, but comparing multiple sources can help understand the accident sequence.
3. Truck Speeding
Speeding is a common cause of truck accidents and is a frequently identified factor. Large commercial trucks have a considerably greater weight and size than passenger vehicles. Controlling and stopping a truck at high speeds can be more difficult. Speeding can be especially dangerous when road conditions are poor, traffic is heavy, visibility is limited, or the truck is traveling downhill. Excessive speed on wet, icy, or slippery roads can further reduce vehicle control.
Investigations may compare the posted speed limit, the truck's estimated speed, road conditions, traffic patterns, and available electronic or physical evidence.
Speed Can Increase Crash Severity
Speed doesn't just affect collision prevention. High speeds can also increase the severity of a crash. A fast-moving heavy truck can generate substantial force during a collision. Therefore, occupants of smaller passenger vehicles may be at risk of serious injuries.
How Can Investigators Determine Truck Speed?
Depending on the case, investigators may examine the following:
- Electronic control module data
- GPS records
- Dashcam footage
- Traffic camera footage
- Skid marks
- Vehicle damage
- Accident reconstruction evidence
- Witness statements
Accident reconstruction experts can analyze available evidence and develop opinions about vehicle movement and speed before a crash.
4. Alcohol or Drug Impairment
Alcohol and drug impairment can also be a serious contributing factor in truck crashes. Impairment can affect a driver's judgment, reaction time, coordination, concentration, and decision-making. In the case of a commercial truck, impairment can be particularly dangerous because the driver is operating an extremely large and heavy vehicle. The investigation may review post-crash alcohol or drug testing results, medical records, witness statements, driver records, and other available evidence.
However, it is important to evaluate testing results in the context of the complete timeline of the accident and other evidence.
Signs of Possible Impairment
Indicators of possible impairment may be examined during an accident investigation:
- Delayed reactions
- Excessive speeding
- Failure to obey traffic controls
- Unusual driving behavior
- Failed testing
- Evidence of prohibited substance use
But a driver should not be assumed to be impaired based solely on an accident. Objective evidence and applicable testing procedures are important.
5. Improper or Overweight Cargo
Cargo loading is an extremely important part of commercial truck safety. Commercial trucks transport different types of cargo, including construction materials, machinery, food products, packaged goods, and industrial equipment. If cargo is not properly loaded or secured, it can shift during transportation. Cargo movement can affect the truck’s balance, stability, steering, braking, and overall handling.
Overweight Cargo
- Braking can increase the distance
- May increase stress on tires
- Suspension may affect components
- Vehicle handling can change
- May create additional stress on mechanical components
Who Loaded the Cargo?
The question of which party loaded the cargo can be important in an accident investigation. Possible parties may include:
- Trucking company
- Shipper
- Warehouse
- Third-party loading company
- Driver
- Logistics providerResponsibility depends on the facts and applicable law.
Cargo Records
Investigators can potentially review:
- Bills of lading
- Weight tickets
- Loading records
- Cargo manifests
- Securement records
- Inspection documents
- Delivery records
These documents can be useful in understanding the condition and handling of the cargo at the time of the accident.
6. Mechanical Failure and Poor Truck Maintenance
Truck maintenance problems can also cause serious commercial vehicle crashes. Commercial trucks travel long distances, and their mechanical systems require regular inspection and maintenance. If important components are not properly maintained, the vehicle's safety and handling can be affected. Potential mechanical problems include brake failure, tire defects, steering problems, suspension issues, lighting failures, worn-out components, or cargo securement problems.
The investigation may include reviewing maintenance records, inspection reports, repair history, and vehicle condition to assess whether a mechanical issue was a contributing factor in the accident.
- Brake failure
- Tire defects
- Tire blowouts
- Steering problems
- Suspension failure
- Defective lights
- Trailer defects
Tire Problems
Tire blowouts can also create serious control problems for truck drivers. Commercial truck tires must handle heavy loads and long-distance driving. Proper inspection and maintenance are important.
7. Truck Blind Spots or “No-Zones”
Large trucks keep around some areas not clearly visible to the driver. Passenger vehicle drivers should maintain extra caution when traveling near trucks.
Lane Change Blind Spot Accidents
Suppose a small car is traveling on the passenger side of a truck. The driver wants to change lanes, but the car may be in the truck's blind spot. If the driver doesn't detect the car and changes lanes, a side-impact collision could occur.
Why Blind Spots Are More Difficult with Large Trucks
Truck mirrors provide the driver with considerable visibility, but despite the mirrors, not every surrounding area is continuously visible. Truck drivers need to check mirrors before lane changes, monitor surrounding traffic, and use appropriate signals.
8. Unsafe Driving Decisions and Poor Training
Truck driving requires specialized skills. Commercial truck drivers must handle different situations while operating large vehicles, including highway merging, wide turns, emergency braking, lane changes, backing, heavy traffic, bad weather, mountain roads, and heavy cargo. A driver with inadequate training or experience may have difficulty handling these situations safely.
Unsafe Company Practices
Depending on the circumstances, investigators may also examine whether a company.
- Hired an inadequately qualified driver
- Failed to provide required training
- Ignored previous safety concerns
- Allowed unsafe driving practices
- Created unrealistic scheduling pressure
- Failed to maintain safety procedures
Company liability does not automatically arise in every case. Specific evidence and applicable state/federal law must be reviewed.
Other Factors That Can Contribute to Truck Crashes
In real truck accidents, multiple contributing factors can often be present simultaneously. For example, fatigue + speeding + poor visibility + mechanical failure + driver error may be involved in the same accident.Therefore, limiting accident investigation to just one obvious factor can sometimes provide an incomplete picture.
How Truck Accident Investigators Determine the Cause
After a serious truck accident, different types of evidence can be compared to establish the cause. The investigator may review police reports, witness statements, photographs, vehicle damage, surveillance footage, electronic records, driver logs, and other available evidence. Truck speed, braking, road conditions, weather, traffic, driver actions, and vehicle maintenance may also be relevant factors. If evidence suggests different explanations, the investigator can compare each possibility against the timeline and available records.
The purpose of this process is to identify contributing factors to the accident and develop the most supported explanation based on the available evidence.
Driver Records
Driver-related evidence may include:
- Driving history
- Training records
- Hours-of-service records

Why Identifying the Cause Matters in a Truck Accident Claim
Identifying the cause of an accident can be an important part of a claim investigation. If evidence shows fatigue, investigators may examine driver logs and dispatch records. If mechanical failure is suspected, maintenance history and repair records may be important. If cargo has shifted, loading records and securement documents may be reviewed. If distracted driving is suspected, available phone, video, electronic, and witness evidence may be investigated.
Can Multiple Parties Be Involved in a Truck Accident?
Yes, depending on the facts, a commercial truck accident investigation may involve multiple parties potentially being relevant. Possible parties may include the truck driver, trucking company, truck owner, leasing company, maintenance provider, cargo loader, shipper, broker, or manufacturer. But a party's connection to a truck accident does not automatically prove legal liability. Evidence must establish how the particular party's conduct was connected to the accident or resulting injuries.
Why Trucking Company Records Can Matter
Commercial trucking companies may maintain different types of operational records. These records can be useful in understanding the circumstances leading up to a crash. Potentially relevant documents may include driver qualification files, employment records, training records, vehicle inspection reports, maintenance records, dispatch communications, hours-of-service records, and electronic logging device data. The investigator can compare these records with the accident timeline and other evidence.
This can help identify factors related to the driver, vehicle, and company operations.
- Training records
- Dispatch communications
- Maintenance records
- Inspection records
- Safety policies
- Electronic logs
- Drug and alcohol testing records
- Cargo documentation
Evidence preservation can be important in serious injury cases because records can become difficult to obtain over time.
What Should You Do After a Truck Accident?
Preserve Photographs and Videos
If possible, preserve photographs of the accident scene, vehicles, road conditions, and visible injuries.
Save Dashcam Footage
If you or a witness has dashcam footage, preserving the original file may be important.
Keep Insurance Communications
Preserve letters, emails, and other communications you receive from your insurance company.
Avoid Destroying Evidence
Do not delete photographs, videos, messages, or documents related to the accident.
Conclusion
The top 8 common causes of truck accidents in the USA include driver fatigue, distracted driving, speeding, alcohol or drug impairment, improper or overweight cargo, mechanical failure, truck blind spots, and unsafe driving or inadequate training.However, every truck accident is different. A crash may involve one primary cause or several contributing factors working together. For example, a fatigued driver who is also speeding may have less time to react to stopped traffic.
Similarly, improper cargo combined with a mechanical problem may make a truck more difficult to control. This is why serious commercial truck accident investigations often require more than simply reviewing the police report. Investigators may need to examine driver records, ELD data, maintenance documents, cargo records, phone evidence, dashcam footage, company records, and accident-scene evidence. If you are injured in a serious truck accident, it may be important to prioritize medical care.
Treat, preserve important evidence, and understand the complete circumstances of the accident.
