A commercial driver's license (CDL) is a driver's license required to operate large or heavy vehicles.

A trailer is not very difficult to categorize. In general, it is an unpowered vehicle towed by a powered vehicle. Trailers are most commonly used for the transport of goods and materials. Although some do enjoy recreational usage of trailers as well. 

In 2009, the book 'Trucking Country: The Road to America's Walmart Economy' debuted, written by author Shane Hamilton. This novel explores the interesting history of trucking and connects certain developments. Particularly how such development in the trucking industry have helped the so-called big-box stored. Examples of these would include Walmart or Target, they dominate the retail sector of the U.S. economy. Yet, Hamilton connects historical and present-day evidence that connects such correlations.

During the latter part of the 20th century, we saw a decline of the trucking culture. Coinciding with this decline was a decline of the image of truck drivers, as they became negatively stigmatized. As a result of such negativity, it makes sense that truck drivers were frequently portrayed as the "bad guy(s)" in movies.

Medium trucks are larger than light but smaller than heavy trucks. In the US, they are defined as weighing between 13,000 and 33,000 pounds (6,000 and 15,000 kg). For the UK and the EU, the weight is between 3.5 and 7.5 tons (3.9 and 8.3 tons). Local delivery and public service (dump trucks, garbage trucks, and fire-fighting trucks) are around this size.

The moving industry in the United States was deregulated with the Household Goods Transportation Act of 1980. This act allowed interstate movers to issue binding or fixed estimates for the first time. Doing so opened the door to hundreds of new moving companies to enter the industry. This led to an increase in competition and soon movers were no longer competing on services but on price. As competition drove prices lower and decreased what were already slim profit margins, "rogue" movers began hijacking personal property as part of a new scam. The Federal Motor Carrier Safety Administration (FMCSA) enforces Federal consumer protection regulations related to the interstate shipment of household goods (i.e., household moves that cross State lines). FMCSA has held this responsibility since 1999, and the Department of Transportation has held this responsibility since 1995 (the Interstate Commerce Commission held this authority prior to its termination in 1995).

The interstate moving industry in the United States maintains regulation by the FMCSA, which is part of the USDOT. With only a small staff (fewer than 20 people) available to patrol hundreds of moving companies, enforcement is difficult. As a result of such a small staff, there are in many cases, no regulations that qualify moving companies as 'reliable'. Without this guarantee, it is difficult to a consumer to make a choice. Although, moving companies can provide and often display a DOT license.

A business route (occasionally city route) in the United States and Canada is a short special route connected to a parent numbered highway at its beginning, then routed through the central business district of a nearby city or town, and finally reconnecting with the same parent numbered highway again at its end.

In some states, a business route is designated by adding the letter "B" after the number instead of placing a "Business" sign above it. For example, Arkansas signs US business route 71 as "US 71B". On some route shields and road signs, the word "business" is shortened to just "BUS". This abbreviation is rare and usually avoided to prevent confusion with bus routes.

In the United States, the Commercial Motor Vehicle Safety Act of 1986 established minimum requirements that must be met when a state issues a commercial driver's license CDL. It specifies the following types of license: - Class A CDL drivers. Drive vehicles weighing 26,001 pounds or greater, or any combination of vehicles weighing 26,001 pounds or greater when towing a trailer weighing more than 10,000 pounds. Transports quantities of hazardous materials that require warning placards under Department of Public Safety regulations. - Class A Driver License permits. Is a step in preparation for Class A drivers to become a Commercial Driver. - Class B CDL driver. Class B is designed to transport 16 or more passengers (including driver) or more than 8 passengers (including the driver) for compensation. This includes, but is not limited to, tow trucks, tractor trailers, and buses.

The American Association of State Highway and Transportation Officials (AASHTO) is an influential association as an advocate for transportation. Setting important standards, they are responsible for publishing specifications, test protocols, and guidelines. All which are used in highway design and construction throughout the United States. Despite its name, the association represents more than solely highways. Alongside highways, they focus on air, rail, water, and public transportation as well.

Logistics is generally the ability to organize and put in place many complex operations at a single time. It is the management of the flow of things to meet the needs of customers or corporations. Resources managed in logistics includes tangible items such as food, materials, animals, equipment, etc. Not to mention the items that are not tangible such as time and information. This means that the movement of physical items, such as in the moving industry, involves a clear understanding of solid workflow. Such logistics can involve the handling of necessary materials, producing, packaging, inventory, transportation, warehousing, and often security.

By the time 2006 came, there were over 26 million trucks on the United States roads, each hauling over 10 billion short tons of freight (9.1 billion long tons). This was representing almost 70% of the total volume of freight. When, as a driver or an automobile drivers, most automobile drivers are largely unfamiliar with large trucks. As as a result of these unaware truck drivers and their massive 18-wheeler's numerous blind spots. The Occupational Safety and Health Administration has determined that 70% of fatal automobile/tractor trailer accident happen for a reason. That being the result of "unsafe actions of automobile drivers". People, as well as drivers, need to realize the dangers of such large trucks and pay more attention. Likewise for truck drivers as well.

Some trailers can be towed by an accessible pickup truck or van, which generally need no special permit beyond a regular license. Such examples would be enclosed toy trailers and motorcycle trailers. Specialized trailers like an open-air motorcycle trailer and bicycle trailers are accessible. Some trailers are much more accessible to small automobiles, as are some simple trailers pulled by a drawbar and riding on a single set of axles. Other trailers also have a variety, such as a utility trailer, travel trailers or campers, etc. to allow for varying sizes of tow vehicles.

In today's society, there are rules and regulations everywhere you go, the same goes for commercial vehicles. The federal government has strict regulations that must be met, such as how many hours a driver may be on the clock. For example, 11 hours driving /14 hours on-duty followed by 10 hours off, with a max of 70 hours/8 days or 60 hours/7 days. They can also set rules deciding how much rest and sleep time is required, however, these are only a couple of regulations set. Any violations are often subject to harsh penalties. In some cases, there are instruments to track each driver's hours, which are becoming more necessary.

Many people are familiar with this type of moving, using truck rental services, or borrowing similar hardware, is known as DIY moving. Whoever is renting a truck or trailer large enough to carry their household goods may obtain moving equipment if necessary. Equipment may be items such as dollies, furniture pads, and cargo belts to protect furniture and to ease the moving process.
