What are the 3 top causes of semi-truck crashes?

On Behalf of | Jul 6, 2025 | Truck accidents

Commercial motorists who operate semi-trucks have to complete more training than other drivers. They have to obtain a commercial driver’s license (CDL) and adhere to strict rules on the road. With years of driving experience, most commercial motorists are excellent at navigating even the most challenging traffic circumstances.

Unfortunately, semi-truck crashes do still occur. They cause thousands of deaths and tens of thousands of injuries every year. People hoping to avoid these types of crashes may benefit from learning about what causes them to better protect themselves in traffic.

What are the most common causes of semi-truck collisions?

1. Improper driving decisions

The Federal Motor Carrier Safety Administration (FMCSA) provides data on semi-truck crashes to help guide safety policies. The FMCSA recognizes inappropriate decisions given traffic conditions as the top cause of semi-truck collisions. Getting too close to other vehicles, maintaining an inappropriate speed and other improper choices account for roughly 38% of the collisions caused by semi-trucks.

2. Recognition errors

Constant surveillance is a key component of safe driving. Unfortunately, many truck collisions relate to recognition errors or a failure to properly monitor surroundings. Large blind spots and distractions at the wheel contribute to this issue. Recognition errors are responsible for approximately 28% of all reported semi-truck collisions.

3. Non-performance

Sometimes, truck drivers don’t make mistakes or fail to do what is necessary for safety. Instead, they become incapable of performing their jobs. Some truck drivers work long shifts and fall asleep at the wheel. Others may experience medical emergencies. Non-performance is responsible for another 12% of commercial trucking collisions.

The FMCSA also recognizes issues with a vehicle and driver performance as other common causes of semi-truck crashes. Holding a driver or their employer accountable can lead to appropriate compensation for those negatively affected by a semi-truck collision.
