ISO 14792:2011规定了确定重型车辆稳态方向控制响应的试验，这是构成车辆动力学和道路保持性能的因素之一。 ISO 14792:2011适用于重型车辆，即ISO 3833中定义的商用车、组合车、客车和铰接式客车，包括UNECE（联合国欧洲经济委员会）和EC车辆法规中的M3、N2、N3、O3和O4类车辆。这些类别适用于最大质量超过3.5 t的卡车和拖车，以及最大质量超过5 t的客车和铰接式客车。

ISO 14792:2011 specifies tests for determining the steady-state directional control response of heavy vehicles, one of the factors composing vehicle dynamics and road-holding properties. ISO 14792:2011 is applicable to heavy vehicles, i.e. commercial vehicles, combinations, buses and articulated buses as defined in ISO 3833, covered by Categories M3, N2, N3, O3, and O4 of UNECE (United Nations Economic Commission for Europe) and EC vehicle regulations. These categories pertain to trucks and trailers with a maximum mass above 3,5 t and to buses and articulated buses with a maximum mass above 5 t.
