According to the Federal Motor Carrier Safety Administration, the most frequent causes of tractor trailer accidents occur when:

  1. The truck driver moves outside his lane of travel into another lane or travels off the road altogether.
  2. The truck driver loses control of his vehicle because his cargo shifts ; he is traveling at a speed faster than conditions allow; he has a vehicle systems failure; or the road conditions are poor.
  3. The truck driver collides with the rear end of the vehicle directly in front of him because he is following too closely.

The following failures by the driver, trucking company, or truck manufacturer may lead to trucking accidents:

  1. Non-Performance: The truck driver falls asleep ; he suffers a sudden medical event like a heart attack or blackout; or he is otherwise physically impaired.
  2. Recognition: The driver is inattentive. He is either distracted by something inside or outside his vehicle or he fails to adequately judge the situation he confronts.
  3. Decision: The driver makes a bad judgment call. He drives too fast for existing conditions; he misjudges the speed of nearby traffic; he follows the vehicles in front of him too closely.
  4. Performance: The truck driver panics, overcompensates, or exercises poor directional control when he confronts a situation demanding a quick response.

There are other factors that can lead to accidents with a large truck. And when these factors come together and you or a loved one is injured, you should consult an 18 wheeler accident lawyer. The Federal Motor Carrier Safety Administration describes frequent reasons including: brake problems, fatigue, prescription or OTC drug use, traveling too fast for road or weather conditions, traffic flow interruption caused by congestion or roadway accidents; the truck driver’s lack of familiarity with the road itself; inadequate lookout; and failure to stop at a traffic signal or crosswalk before a crash occurs.

Certain factors also increase the risk that an accident will happen. These include shifting cargo and the following conditions and conduct that are associated with the driver such as illness, illegal driving maneuvers, following too closely and inattention. Shifting cargo also increases the risk of a trucking collision.
