This List of truck types is intended to classify trucks and to provide links to articles on the various types. The three main classifications for road truck by weight are light trucks, medium trucks, and heavy trucks. Above this there are specialised very heavy trucks and transporters such as heavy haulers for moving oversized loads, and off-roadheavy haul trucks used in mining which are too large for highway use without escorts and special permits.<ref>Truck Financing Guide</ref>
