Causes of Large Truck Accidents In Houston & US

In a recent study conducted by the Federal Motor Carrier Safety Administration (FMCSA) and the National Highway Traffic Safety Administration (NHTSA), the main causes of large truck accidents were revealed. These crashes often lead to serious injuries or fatalities, and understanding what leads to them can help prevent future incidents. This study focused on accidents where trucks over 10,000 pounds were involved and resulted in injury or fatality. By analyzing 963 crashes, the study uncovered key factors that contribute to large truck accidents.

1. Driver-Related Causes

The study revealed that driver-related factors were responsible for the majority (87%) of crashes involving large trucks. These factors were divided into several categories:

• Non-Performance: In 12% of crashes, the driver was unable to perform due to fatigue, falling asleep, or a medical emergency such as a heart attack.
• Recognition: In 28% of cases, the driver failed to notice the situation adequately, often due to distractions inside or outside the vehicle.
• Decision Errors: Driving too fast for conditions, misjudging the speed of other vehicles, or following too closely contributed to 38% of crashes.
• Performance Errors: In 9% of cases, poor performance such as overcompensating or losing control of the vehicle led to accidents.

2. Vehicle Issues

Vehicle-related problems, such as brake or tire failure, contributed to 10% of the crashes. Brake problems were the most frequently reported issue, significantly increasing the risk of an accident. Trucks with brake problems were 2.7 times more likely to be involved in a crash compared to those without brake issues.

3. Environmental Factors

Environmental factors, such as poor road conditions or bad weather, played a role in 3% of large truck accidents. These factors included slippery roads, debris, or inadequate signage, which made it difficult for drivers to maintain control.

4. Critical Events Leading to Accidents

The study identified three main critical events that made collisions inevitable:

• Running Out of the Travel Lane: 32% of accidents involved trucks veering out of their lane or off the road.
• Loss of Vehicle Control: In 29% of accidents, the truck lost control due to factors such as excessive speed, cargo shift, or vehicle failure.
• Rear-End Collisions: 22% of crashes involved trucks colliding with the rear of another vehicle in their lane.

5. Additional Associated Factors

Several additional factors increased the likelihood of large truck accidents, including:

• Fatigue: Driver fatigue was present in 13% of crashes and significantly raised the risk of an accident.
• Inadequate Surveillance: In 14% of accidents, drivers failed to properly assess their surroundings, leading to crashes.
• Driving Under Pressure: In 10% of accidents, drivers felt pressure from their employer to meet deadlines, contributing to poor decision-making.

Conclusion

The Large Truck Crash Causation Study highlights the complexity of factors that contribute to accidents involving large trucks. While driver-related issues like fatigue, distractions, and poor decision-making were the most common causes, vehicle and environmental factors also played a significant role. Understanding these causes can help inform policies and practices aimed at reducing the risk of large truck accidents and improving road safety for all drivers.
