What is a Large Vehicle License?

[McAustin]

Large vehicle license refers to the B2 license. Below are the vehicle types permitted with a B2 license and precautions for driving large trucks. Vehicle types permitted with a B2 license: A B2 license allows the holder to drive heavy or medium-duty trucks, as well as large, heavy, or medium-sized specialized operation vehicles. Heavy and medium-duty trucks are mostly trucks, such as the large dump trucks commonly seen on the road, which fall under the category of heavy-duty trucks. Precautions for driving large trucks: First, it is important to understand the characteristics of heavy-duty trucks. Heavy-duty trucks have a large mass and high inertia; their center of gravity is high, leading to significant centrifugal force. They have a long body, occupying more space. The wheelbase is long, resulting in a large inner wheel difference. They use air brakes, which provide quick braking response. The steering wheel is larger and responds slower compared to smaller vehicles. They have multiple gears (six or more) with small gaps between them, making the operation more complex and demanding than driving smaller vehicles.
