The History of Semi-Trucks

Semi-trucks, also called tractor-trailers, transport 71.4% of the nation’s freight according to the American Trucking Associations (ATA). These vehicles and their drivers play an essential role in our nation’s economy and this has been the case for decades. Since their invention, semi-trucks have been an important factor in keeping our country running smoothly.

The Invention of Semi-Trucks

Alexander Winton was a Scottish immigrant and inventor who lived in Cleveland, Ohio, in the late 19th and early 20th centuries. He originally produced bicycles until he started the Winton Motor Carriage Company in 1897. They produced “horseless carriages.” This was an early name for automobiles.

When Winton started to sell his vehicles, he realized that he needed a more efficient way to transport the cars. Many buyers lived hundreds of miles from Cleveland and driving the automobiles individually caused unnecessary wear and tear. In order to solve this problem, Winton created trucks with an attached trailer to transport his cars. He invented what he called the “automobile hauler” in 1898 and sold the first manufactured semi-truck in 1899.

A Detroit blacksmith, August Charles Fruehauf, created a similar vehicle in 1914. Fruehauf was the first to use the term “semi-trailer,” which eventually evolved into the phrase “semi-trailer truck.” This was shortened to “semi-truck,” creating the term we use today.

Trucking Industry Growth

There were several factors that led to the trucking industry’s growth.

These include:  

Advancements in Semi-Truck Design

The first semi-trucks were not very comfortable or easy to drive. This limited their usefulness and trains were a more popular method for hauling freight. One of the most important advancements was the creation of running lights. This meant that by 1912, semi-trailers could travel at night. As a result, they were more efficient and became a more attractive option for shipping goods. This advancement helped them compete with train companies.

Logging Industry

The growth of the logging industry created a need for vehicles that could effectively transport lumber. In 1939, the Peterbilt truck company created trailers to haul logs by refurbishing Army trucks. Peterbilt continues to manufacture semi-trucks to this day.

The National Highway System

President Dwight D. Eisenhower authorized the construction of the Interstate Highway System in 1956. This created a network of roads for transport across the continental United States. As a result of the new highway system, semi-trucks could travel more easily.

Modern Innovations

Today, truck manufacturers continue to introduce new technology to improve semi-trucks. This includes innovations related to safety and monitoring, such as electronic logging devices (ELDs). There have also been improvements for fuel efficiency and driver experience.

Trucking Safety Tips for Drivers

Operating a large truck requires additional precautions compared to driving a smaller vehicle. Trucking safety is essential because an accident involving a tractor-trailer can have a huge impact. Safe driving not only keeps the driver and their freight safe but also helps protect everyone else on the road.

Here are some factors commercial drivers should be aware of:

Before Your Trip

Driver Health

It is important for truck drivers to be in good health. The Department of Transportation (DOT) requires physicals every 24 months for those operating commercial motor vehicles. In addition to completing these mandatory check-ups, you should also monitor your health and avoid driving if you are too sick to focus on the road.

Do Not Drive Impaired

You should not drive if you are impaired in any way. This includes not drinking before any trips and not using controlled substances at any time. In addition, you should be well-rested, as a lack of sleep can also result in impairment.

Pre-Trip Inspection

Before you start driving, you need to complete a pre-trip inspection of your commercial motor vehicle. There are multiple parts you must check to ensure your truck is safe to drive.

While Driving

Speed Limits

Maintaining a safe speed is important for all drivers. The National Highway Traffic Safety Administration (NHTSA) found that driving above the speed limit was a factor in 26% of motor vehicle accidents in 2017. Speeding is even more dangerous for semi-trucks. This is because the stopping distance for large trucks is already greater than standard vehicles. The higher your speed, the longer it will take to stop. Truck drivers should always follow posted speed limits and adapt their speed to road conditions.

Avoiding Jackknifing

A jackknife is a form of skid that occurs when the trailer portion of a semi-truck folds in toward the cab at an acute angle. Accidents involving jackknife can be fatal to the truck driver or any others involved, so it is important to take proper care to avoid this issue. This includes slowing down on curvy roads, properly loading the vehicle, and turning slowly and carefully.

Awareness of the Road

Staying aware of the road is one of the most important things you can do as a driver. You should keep an eye out for any hazards and always be prepared to take necessary action to avoid them. The commercial driver’s license (CDL) manual recommends looking 12 to 15 seconds ahead at all times while also paying attention to conditions closer to your truck.
