Truck
Overview
A truck is a motor vehicle designed for transporting cargo. Unlike passenger cars, it features a separate or integrated cargo area. Trucks form the backbone of modern logistics systems and play an essential role in transporting various goods—such as raw materials, finished products, and foodstuffs—in economic activities. They range in type and size from small pickup trucks to large dump trucks and trailers, and are classified in various ways according to engine, fuel, and purpose.

History and Development
The origins of the truck trace back to the late 19th century with steam-powered freight vehicles. In 1896, German engineer Gottlieb Daimler built the first internal combustion engine truck, and later, in the early 20th century, companies like Ford and Mercedes-Benz established mass production systems. After World War II, the expansion of highway networks and the development of containerized freight systems led to rapid growth in truck transport. Following the oil shocks of the 1970s, fuel efficiency and emission regulations tightened, advancing diesel engine technology. Recently, electric and hydrogen trucks have entered the commercialization stage.
Types of Trucks
Trucks are broadly classified by purpose and structure. Light trucks include pickup trucks (e.g., Ford F-150, Hyundai Porter) and 1-ton trucks, used for personal and small business purposes. Medium trucks range from 2.5 to 5 tons and are used for delivery, garbage collection, etc. Heavy trucks are 5 tons or more and are built for specialized purposes such as dump trucks, concrete mixer trucks, refrigerated trucks, and tanker trucks. Trailer trucks consist of a tractor (towing vehicle) and a trailer (towed vehicle) and are used for long-distance bulk transport. Additionally, based on loading methods, trucks are divided into flatbed trucks, van-type trucks, and wing-body trucks.
Structure and Technology
A truck mainly consists of an engine, chassis, cab (driver's compartment), and cargo bed. Most engines use diesel, with turbochargers and intercoolers to boost output and efficiency. Recently, to meet stricter emission standards such as Euro 6 and EPA10, selective catalytic reduction (SCR) systems and diesel particulate filters (DPF) have become mandatory. Transmissions are shifting from manual to automated manual transmissions (AMT) and automatic transmissions, contributing to improved fuel economy and reduced driver fatigue. Advanced driver assistance systems (ADAS), including lane departure warning, automatic emergency braking, and adaptive cruise control, are increasingly being introduced in heavy trucks.
Economic and Social Impact
Truck transport accounts for approximately 70% of global logistics, making it a crucial pillar of the economy. The role of trucks is particularly irreplaceable in 'last mile' delivery. However, issues such as long working hours for truck drivers, poor working conditions, and labor shortages remain social challenges. Additionally, accidents involving heavy trucks can lead to significant loss of life, prompting stricter safety regulations. Trucks are also a major target of environmental regulations due to their high carbon emissions.
Latest Trends
In 2024–2025, the trucking industry is undergoing two revolutions: electrification and autonomous driving. Electric trucks such as the Tesla Semi, Volvo VNR Electric, and Daimler's eActros have begun commercial operations in North America and Europe. In 2025, Hyundai Motor's hydrogen electric truck 'XCIENT' entered the European market in earnest. Advances in battery technology have increased the driving range per charge to over 500 km, making electric trucks economically viable for short- and medium-haul routes. In the autonomous driving sector, companies like Waymo, TuSimple, and Aurora are testing highway autonomous trucks, and in 2025, Level 4 unmanned trucks have been partially commercialized in some regions. Connected truck technology has also advanced, enabling real-time remote diagnostics, platooning, and optimal route guidance. In South Korea, from 2025, the installation of 'safe driving support devices' on heavy trucks has been mandated, and policies are being pursued to expand truck rest areas and improve driver treatment.
