What Are Tractor-Trailers?
You may hear the term tractor-trailer tossed around a lot, but what exactly is a tractor-trailer? The term tractor-trailer does not encompass all large trucks on the road. For example, a box truck is not a tractor-trailer, nor is a dump truck. So what defines a tractor-trailer? Let’s look at the anatomy of the typical truck on the road.
The Dangers That Exist With Tractor-Trailers
Just look at a tractor-trailer parked next to the standard mid-size car, and you can immediately see where the inherent danger lies. However, the dangers extend far beyond the sheer size of these vehicles. The design, mechanics, and even the drivers can all add additional risk. Take a look at a few facts that illustrate the dangers of tractor-trailers:- A fully loaded tractor-trailer traveling at 65 miles per hour takes the length of two football fields to stop. To put that in perspective, that is 65 percent farther than it takes for a mid-size car traveling the same speed to stop.
- In 2017, the year in which the most recent numbers are available, 4,889 large trucks were involved in fatal accidents nationwide.
- In Illinois, tractor-trailers played a role in 3.5 percent of crashes overall, but nearly 10 percent of all fatal accidents, in 2017.
- Semi-truck drivers have blind spots all around them. In the front, the blind spot extends 20 feet in front of the cab. At the rear, the blind spot goes back 30 feet. On each side, the driver has a limited view of the adjacent lanes. As a rule of thumb, if you can’t see the truck’s side mirrors, the driver can’t see you.
Common Causes of Tractor-Trailer Accidents
Driving a tractor-trailer takes skill and training. Not just anyone can drive a large truck. Truck drivers know the responsibility that comes with driving these vehicles, and most give the job the care and attention that it deserves. So why do so many accidents continue to happen?- Speeding: Truck drivers speed for a variety of reasons. They may be behind schedule, tired, or unfamiliar with the area. Regardless of the reason, speeding is dangerous, especially when it comes to large trucks. Speeding increases the amount of time it takes to stop and reduces the amount of time available to react. This combination can be deadly if a vehicle or other hazard enters the truck’s path.
- Distracted driving: Truckers work long hours, often spending days away from home. Some drivers may turn to their mobile devices to ease the boredom or loneliness. The time it takes to do something as simple as changing the station on a music app is enough to cause the truck to drift into another lane, miss a car move in front of them, or slide into a blind spot.
- Mechanical issues: The law requires drivers to inspect their vehicles before each shift. In addition, they must undergo annual inspections. Sometimes, important flaws are missed, and other times, the inspection gets skipped altogether. Even if the driver complies with all inspections, improper maintenance can still cause an accident.
Determining Liability

- The driver: Drivers have a responsibility to maintain their truck and to practice safe driving habits. When they fail to uphold this responsibility, their insurance companies may be responsible for covering damages.
- The driver’s employer: The employer is usually the person that owns the truck and hired the driver. If the employer did not ensure that the vehicle was safe, provided inadequate training, pushed the driver to work beyond the legal limits, or knowingly put an unsafe driver on the road, the employer may hold liability. The owner would also typically be liable for damages under an agency theory.
