Cabin (truck)
Conventional cabs are the most common in North America and Australia. The driver is seated behind the engine, as in most passenger cars or pickup trucks. Conventionals are further divided into "large car" and "aerodynamic" designs, as opposed to underneath with no nose like in a cab over. A "large car" or "long nose" is a conventional truck with a long (6 to 8 foot (1.8 to 2.4 m) or more) hood. With their very square shapes, these trucks experience a lot of wind resistance. They typically consume more fuel. They also provide somewhat poorer visibility than their aerodynamic or COE counterparts. By contrast, Aerodynamic cabs are very streamlined. They have a sloped hood and other features to lower drag. The front doors are behind (and mostly above) the front tires. Access to a conventional cabin is commonly by steps at or near the fuel tank(s) behind the front tires.
