A semi-trailer truck, is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a type of hitch called a fifth wheel.
A truck or lorry is a motor vehicle designed to transport freight, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "tractor".
Road transport or road transportation is a type of transport using roads. Transport on roads can be roughly grouped into the transportation of goods and transportation of people. In many countries licensing requirements and safety regulations ensure a separation of the two industries. Movement along roads may be by bike, automobile, bus, truck, or by animal such as horse or oxen. Standard networks of roads were adopted by Romans, Persians, Aztec, and other early empires, and may be regarded as a feature of empires. Cargo may be transported by trucking companies, while passengers may be transported via mass transit. Commonly defined features of modern roads include defined lanes and signage. Various classes of road exist, from two-lane local roads with at-grade intersections to controlled-access highways with all cross traffic grade-separated.
A road train, also known as a land train or long combination vehicle (LCV) is a semi-truck used to move road freight more efficiently than single-trailer semi-trucks. It consists of one semi-trailer or more connected together with or without a tractor. It typically has to be at least three trailers and one tractor.
Commercial vehicle operations (CVO) is an application of intelligent transportation systems for trucks. It would allow trucks and buses to travel without having to stop for weight, credential, and safety checks, by using highway sensors to check them automatically as they are driven at prevailing speeds.
Weigh-in-motion or weighing-in-motion (WIM) devices are designed to capture and record the axle weights and gross vehicle weights as vehicles drive over a measurement site. Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a stop. This makes the weighing process more efficient, and, in the case of commercial vehicles, allows for trucks under the weight limit to bypass static scales or inspection.
A truck driver is a person who earns a living as the driver of a truck, which is commonly defined as a large goods vehicle (LGV) or heavy goods vehicle (HGV).
Via Verde is an electronic toll collection system used in Portugal since April 1991. It is available at all toll roads and bridges in the country since 1995. Toll roads and bridges are operated by multiple operators, the main being Brisa - Auto-estradas de Portugal.
A weigh station is a checkpoint along a highway to inspect vehicular weights and safety compliance criteria. Usually, trucks and commercial vehicles are subject to the inspection.
A truck scale (US), weighbridge (non-US) or railroad scale is a large set of scales, usually mounted permanently on a concrete foundation, that is used to weigh entire rail or road vehicles and their contents. By weighing the vehicle both empty and when loaded, the load carried by the vehicle can be calculated.
The Louisiana Department of Transportation and Development (DOTD) is a state government organization in the United States, in charge of maintaining public transportation, roadways, bridges, canals, select levees, floodplain management, port facilities, commercial vehicles, and aviation which includes 69 airports, in the U.S. state of Louisiana. The agency has approximately five thousand personnel on staff and an operating budget of $2.3 billion. DOTD operations are run through nine district offices across the state.
Arthur Theodore Bergan is a Canadian civil engineer and professor. He specializes in transportation engineering. He supervised the construction of highways and the development of Transport Canada's Transportation Centers. He supervised the development of the Weigh-in-Motion Scale, designed to weigh vehicles passing over computer-assisted scales at speeds up to 70 miles per hour.
PrePass is an intelligent transportation system (ITS) that electronically verifies the safety, credentials, and weight of commercial vehicles as they approach participating state highway weigh stations. Because they comply electronically, commercial carriers enrolled in PrePass are authorized to bypass these facilities rather than pull in for manual inspection.
The Federal Bridge Gross Weight Formula, also known as Bridge Formula B or the Federal Bridge Formula, is a mathematical formula in use in the United States by truck drivers and Department of Transportation (DOT) officials to determine the appropriate maximum gross weight for a commercial motor vehicle (CMV) based on axle number and spacing. The formula is part of federal weight and size regulations regarding interstate commercial traffic. The formula is necessary to prevent heavy vehicles from damaging roads and bridges. CMVs are most often tractor-trailers or buses, but the formula is of most interest to truck drivers due to the heavy loads their vehicles often carry.
The trucking industry serves the American economy by transporting large quantities of raw materials, works in process, and finished goods over land—typically from manufacturing plants to retail distribution centers. Trucks are also used in the construction industry, two of which require dump trucks and portable concrete mixers to move the large amounts of rocks, dirt, concrete, and other building materials used in construction. Trucks in America are responsible for the majority of freight movement over land and are tools in the manufacturing, transportation, and warehousing industries.
A specialized set of jargon describe the tools, equipment, and employment sectors used in the trucking industry in the United States. Some terms may be used within other English-speaking countries, or within the freight industry in general. For example, shore power is a term borrowed from shipping terminology, in which electrical power is transferred from shore to ship, instead of the ship relying upon idling its engines. Drawing power from land lines is more efficient than engine idling and eliminates localized air pollution. Another borrowed term is "landing gear", which refers to the legs which support the front end of a semi-trailer when it is not connected to a semi-truck. Some nicknames are obvious wordplay, such as "portable parking lot", in reference to a truck that carries automobiles.
The Highway Traffic Act is a statute in Ontario, Canada, which regulates the licensing of vehicles, classification of traffic offences, administration of loads, classification of vehicles and other transport-related issues. First introduced in 1923 to deal with increasing accidents during the early years of motoring in Ontario, and replacing earlier legislation such as the Highway Travel Act, there have been amendments due to changes to driving conditions and new transportation trends. For example, in 2009, the Act was revised to ban the use of cell phones while driving.
The trucking industry in the United States has affected the political and economic history of the United States in the 20th century. Before the invention of automobiles, most freight was moved by train or horse-drawn vehicle.

Drivewyze is an intelligent transportation system (ITS) service that provides bypasses to commercial vehicles as they approach participating state highway weigh stations. The participating vehicles' safety record, credentials and weight are verified automatically, and if they comply with that state's screening rules for automated bypass, the vehicles are authorized to bypass these facilities rather than pull in for manual inspection. This results in time and fuel savings for the truck and less vehicle congestion at the weigh station.
