Car and semi truck accident

Colorado is a major national trucking and transportation hub with 2 major interstates - I-25 and I-70 that intersect in Denver. Because of this, it's common for drivers on the Front Range to be sharing the roads with Interstate 25 traffic heading into Denvercommercial trucks, semi-trucks and other large transportation vehicles, creating situations that demand attention to safety for everyone on the roads. At Metier Law Firm Car and Truck Accident Lawyers, we've represented numerous victims of accidents involving semi-trucks and large commercial trucks, giving us unique insight into the most common causes of these devastating crashes. In this blog, we're going to highlight the top causes of semi-truck crashes so that all drivers can be aware and safer sharing the roads with these heavy and large trucks.

1. Driver Fatigue: A Silent but Deadly Threat

Despite federal regulations limiting driving hours, fatigue remains one of the most dangerous factors in commercial truck accidents. 18 wheeler trucks (also known as "tractor-trailers", "big rigs" or "semis"), weighing up to 80,000 pounds, require attentive operators at all times. Our truck accident attorneys have seen countless cases where driver exhaustion led to devastating consequences. Companies sometimes pressure drivers to meet unrealistic deadlines, leading to compromised rest periods and increased accident risks.

2. Excessive Speed: When Minutes Cost Lives

Big rigs and semi-trucks have significantly longer stopping distances than passenger vehicles, making speed management crucial. When these massive vehicles exceed speed limits, their momentum becomes nearly impossible to control. High-speed truck accidents often result in catastrophic injuries or fatalities, particularly when weather conditions are less than ideal.


3. Driver Inexperience: The Training Gap

The current driver shortage has led some companies to take shortcuts with their training programs, putting inexperienced drivers behind the wheels of big rigs. These newer commercial truck drivers often lack the judgment and skills necessary to handle emergency situations, bad weather or driving conditions, or complex driving situations. Our firm has seen a concerning increase in accidents involving truck drivers with limited experience. 


4. Mechanical Failures: Where Maintenance Matters Most

Regular maintenance isn't just a recommendation—it's a federal requirement for commercial trucks. Yet, we continue to see accidents caused by brake failures, tire blowouts, and steering malfunctions. These mechanical failures often result from ignored maintenance schedules or cost-cutting measures that put profits ahead of safety.

5. Cargo Loading Issues: An Often Overlooked Danger

Proper cargo distribution and securing is a critical safety requirement. When loaders rush or cut corners, the consequences can be severe. Shifting cargo can cause trailers to jackknife or roll over, while unsecured loads may spill onto highways, creating hazardous conditions for other drivers. Our experience with semi-truck accident cases has shown that improper loading is often traceable to systemic safety violations. Commercial trucks require special handling in adverse weather conditions. Cars on Interstate 70 going to the mountainsRain, snow, ice, and fog demand reduced speeds and increased following distances. Unfortunately, many commercial truck drivers fail to adjust their driving for weather conditions, leading to preventable accidents. This is particularly crucial when these 18 wheeler trucks encounter sudden weather changes in mountainous or variable climate regions.

7. Aggressive Driving Behaviors: A Professional's Greatest Mistake

Semi-truck drivers are held to higher standards than regular motorists. However, aggressive driving behaviors such as tailgating, unsafe lane changes, and road rage incidents continue to cause accidents. Our truck accident attorneys have successfully represented numerous clients injured by commercial drivers who abandoned their professional responsibilities.


8. Distracted Driving: Modern Threats to Road Safety

The rise of mobile devices and in-cab technologies has introduced new dangers to commercial trucking. Even a moment's distraction can result in a truck traveling hundreds of feet without driver attention. Whether it's texting, adjusting GPS systems, or eating while driving, these distractions have proven deadly in many cases we've handled.


9. Traffic Law Violations: Breaking Rules, Breaking Lives

Semi-truck drivers must adhere to both standard traffic laws and additional regulations specific to their industry. When they ignore these rules—whether by running red lights, following too closely, or making illegal turns—they put everyone at risk. These violations often form the foundation of successful legal claims for accident victims.


10. Substance Impairment: An Unacceptable Risk

Despite strict regulations and regular testing, substance use continues to plague the trucking industry. Alcohol, illegal drugs, and even certain prescription medications can severely impair a truck driver's ability to operate their vehicle safely. Our experience has shown that companies must maintain vigilant screening programs to prevent impaired driving incidents.
