18-Wheeler Accidents in Texas

Texas 18-wheeler accidents

Accidents involving 18-wheelers are often more complex than traditional car accidents

In Texas, 18-wheelers are a common sight. Accidents involving 18-wheelers often cause serious damage and it’s not always easy to determine who’s at fault.

In 1899, automobile manufacturer Alexander Winton wanted to distribute his vehicles to customers around the country without putting mileage on them. His solution was to attach a cart to the back of a modified truck. The invention became known as the world’s first “semi-truck.”

Today, there are roughly 3 million semi-trucks registered in the United States—most of them much larger than Alexander Winton’s. Today’s semi-trucks are generally 70-80 feet long, have 18 wheels, and weigh as much as 80,000 pounds (40 tons).

Though 18-wheelers are a huge part of the nation’s economy, especially here in Texas, their substantial size and prevalence create the potential for serious traffic accidents.

Facing factsAccording to the National Highway Traffic Safety Administration, 79% of large trucks involved in fatal traffic crashes in 2017 weighed more than 26,000 pounds.

What’s more, 18-wheeler accidents tend to be more complicated than accidents involving smaller vehicles.

Let’s take a look at 18-wheeler accidents in the Lone Star State.

What is an 18-wheeler?

An 18-wheeler is a truck consisting of a tractor and a trailer, and typically has 18 wheels. Most people use terms like “18-wheeler,” “big rig,” and “semi-truck” interchangeably to describe any large commercial truck.

Legally speaking, large trucks are regulated based on vehicle weight and cargo type. For that reason, it’s generally not relevant that a truck has 10 wheels or 16 wheels as opposed to 18 wheels. 

Nevertheless, let’s learn a little more about the average 18-wheeler.

Common questions about 18-wheelers

How big is an 18-wheeler’s engine?

Unsurprisingly, engines in 18-wheelers are much larger than engines in smaller cars. Most 18-wheeler engines are 6 times larger than the engines in smaller cars. Large engines are necessary to provide torque. Torque is what helps an 18-wheeler tow massive amounts of cargo and keep all 18 wheels turning.

What is a 5th wheel?

The 5th wheel on an 18-wheeler refers to the round plate above the drive tires that hooks the trailer and the truck together.

What is “bobtailing”?

Bobtailing is the term used to refer to a truck driving without the trailer attached. Trucks don’t handle well when bobtailing and can be particularly dangerous in wet weather.

What is the turn radius for an 18-wheeler?

An 18-wheeler needs 55 feet of turning radius. This is one of the reasons why 18-wheelers have such large side mirrors, and also one of the reasons why truck drivers must be proficient in backing up (most roads are only 24 feet wide).

How many miles per gallon does the average 18-wheeler get?

The most fuel efficient 18-wheelers only get 8.9 miles per gallon. Side skirts that prevent wind turbulence under the trailer and round caps placed over the trailer doors are a couple ways to improve fuel-efficiency.

How much do we rely on 18-wheelers?

Recent estimates indicate that roughly 70% of all products in the United States are delivered by 18-wheelers. What’s more, 18-wheelers drive roughly 175 billion miles per year.

Common types of 18-wheeler accidents

Like other large commercial vehicles, the size of 18-wheelers makes them prone to several accident types, including:

Common causes of 18-wheeler accidents?

All sorts of factors can contribute to an 18-wheeler accident.

Some of the most common contributing factors include:

How does an 18-wheeler accident differ from other types of accidents?

As is the case with all motor vehicle accidents, first you have to establish liability in order to receive compensation for any injuries or damages you suffer in the accident.

There are 2 main differences between 18-wheeler accidents and most car accidents:

  1. Commercial truck drivers and trucking companies are subject to federal and state regulations that don’t apply to other motor vehicles.
  2. Several parties that may be liable for an 18-wheeler accident aren’t normally liable in other motor vehicle accidents.

Let’s dive a little deeper into both these differences.

First, truck drivers and trucking companies in Texas must comply with the Federal Motor Carrier Safety Administration laws as well as the state laws located in Title 7 of the Texas Transportation Code. These laws address everything from maximum cargo weight to consecutive hours a truck driver can drive without a break.

If a truck driver or trucking company violates any of these laws and an accident results, proving liability becomes considerably easier for the injured person.

Second, several people and entities that may be liable for an 18-wheeler accident depending on the circumstances, including:

  • The truck driver. The truck driver may be at fault if their negligence caused the accident—for example, if the truck driver ran a red light or was driving while intoxicated.
  • The trucking company. The trucking company may be at fault (or partially at fault) if they violated a federal or state law (such as requiring the truck driver to drive for a longer period than permitted). It’s also possible that the trucking company will be held liable for the negligence of the truck driver under the theory of respondeat superior.
  • The cargo company. One common cause of truck accidents is overloaded or improperly loaded cargo. In these situations, a cargo company may be at fault.
  • The manufacturer. Truck accidents are sometimes the result of a defective vehicle part. In these situations, the manufacturer of the defective product might be at fault.

In some cases, both you and the truck driver (or some other party associated with the truck) may be at fault for the accident. Texas follows what is called the modified comparative fault rule. Under this rule, the degree to which you can recover damages is limited to your degree of fault.

For example, if a judge or jury finds you 30% at fault, you can only recover 70% of your damages. Importantly, if you’re more than 50% at fault, you can’t recover any damages.

Do you need a truck accident attorney?

Accidents involving 18-wheelers tend to cause significant damage. As a result, insurers are reluctant to simply pay the damages without a fight.

An experienced Texas attorney can investigate the cause of the accident, identify all the potentially liable parties, negotiated with the insurance company, and take the case to trial if necessary.

Are trucks required to have black boxes?

The Federal Motor Carrier Safety Administration requires all commercial trucks and 18-wheelers to carry electronic logging devices (ELDs). These devices log the number of hours a driver spends behind the wheel to ensure that the trucker complies with the laws limiting the number of hours a truck driver can drive consecutively.

Many 18-wheelers are also equipped with event data recorders (EDRs). These devices are similar to the “black boxes” found in airplanes and record the events leading up to an accident, including the speed, location, and brake usage.

An attorney can help you obtain these devices to see if the information may help your case.
