VFIS Emergency Vehicle Driver Training (EVDT) Instructor Practice Test

The idea being tested is how the position of the cab relative to the engine is described in truck design. Cab over the engine describes a layout where the cab sits directly above the engine compartment, resulting in a flat-fronted cab with no long hood. This design is chosen for shorter overall length and tighter maneuverability, since the engine isn’t offset in front of the cab.

A conventional cab has the engine in front of the cab with a distinct long hood, so it isn’t cab over the engine. A rear-engine cab places the engine behind the cab, not under or above it. Forward control is a term often used to describe a cab-over style in which the driver sits above or very close to the engine, but the specific phrase cab over the engine clearly matches the description in the question.
