ISO 14791:2000

Road vehicles - Heavy commercial vehicle combinations and articulated buses - Lateral stability test methods

This International Standard specifies test methods to determine the lateral stability of heavy commercial vehicle

combinations as defined in ISO 3833, including truck centre-axle trailer combinations and articulated buses. It is

applicable to trucks and trailers having a mass exceeding 3,5 t and buses having a mass exceeding 5 t, i.e. vehicle

categories N2, N3, O3, O4 and M3 according to 92/53/EEC.

The manoeuvres specified in these test methods are not fully representative of real driving conditions, but are

useful for determining the lateral stability of a heavy vehicle combination.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.
