Quick Answer: Who Is At Fault Most Often In Tractor-trailer Crashes?

The Large Truck Crash Causation Study

The Large Truck Crash Causation Study (LTCCS) looked into the causes of serious truck crashes, with 73 percent of the 963 crashes involving a large truck colliding with at least one other vehicle, resulting in 249 fatalities and 1,654 injuries.

Defining Causation

The term ‘causation’ refers to the factors that are most likely to increase the risk of large trucks being involved in serious crashes. Fatigue, drinking alcohol, and speeding are all major factors in motor vehicle crashes, but other elements, such as a decision to turn in traffic, can happen right before a crash.

Data Collection

Crash scene data for the 963 crashes in the LTCCS sample was collected at 24 locations in 17 states by a crash researcher and a state truck inspector who went to each crash site as soon as possible after the crash and conducted interviews with drivers, passengers, and witnesses.

National Crash Estimates

The results presented here are national estimates for the 141,000 large trucks involved in fatal and injury crashes during the 33-month study period. Because the estimates are based on a probability sample of crashes rather than a census of all crashes, they may differ from true values.

Coding Crash Causation Variables

The hundreds of data elements collected on each crash were coded into many variables. Critical Event: The action or event that put the vehicle or vehicles on a course that made the collision unavoidable. Associated Factors: The person, vehicle, and environmental conditions present at the time of the collision.

Critical Reasons

The percentage of large trucks coded with a critical reason varies by crash type, as shown in Table 1. Driver critical reasons are classified into four categories: non-performance, performance, decision, and recognition. Estimates are rounded to the nearest 1,000 large trucks.

Relative Risk

A truck with brake problems was 170 percent more likely to be coded with the critical reason for a crash than a truck that was not coded with it, according to a relative risk analysis of the data on associated factors using the critical event and critical reason coding.

Table 2 

Excessive speed, inadequate surveillance, illegal maneuver, inattention, and following to the right are factors that can increase the risk of serious injury or death in large truck crashes. Of the 19 factors listed in Table 2, 15 are driver factors. Pre-crash cargo shift had the highest relative risk ratio (56.3), with only 4% of crashes reported.

Large Truck – Passenger Vehicle Crashes

There was a statistically significant link between the following 10 associated factors and coding of the critical reason for each type of crash for both large trucks and passenger vehicles in half of the LTCCS crashes, and there was a statistically significant link between the following 10 associated factors and coding of the critical reason for each type of crash for both large trucks and passenger vehicles.

What is the number one cause of truck accidents?

The most common cause of truck accidents is driver fatigue, which is caused by truck owners who demand the delivery of goods to specific destinations in a short period of time. Most truck drivers normally drive over long distances for many hours with very little rest in between.

Why are trucking accidents a serious issue?

Aside from the weight factor, the driver of a large commercial truck is usually riding high up in the cab, while the driver of a car is much lower to the ground. Truck accidents are especially frightening because they are more likely to result in death or serious injury than a collision between two passenger cars.

How common are trucking accidents?

In fact, approximately 500,000 trucking accidents occur in the United States each year, with about 5,000 resulting in death.

How do semi trucks make right turns?

Trucks must swing wide to make a 90-degree right turn, and must start a turn from the second lane to the left, rather than the right turn lane, because large commercial vehicles, particularly semis with a tractor and trailer, cannot turn in the same small radius as a personal car. Trucks must start a turn from the second lane to the left, rather than the right turn lane.

What distance does it take a fully loaded truck to come to a complete stop when traveling at 55 mph?
