3.4.2

vehicle security barrier datum line

VSB datum line

horizontal line marked on the ground pre-impact, vertically aligned with the foremost point of the vehicle security barrier (VSB) (3.1) structure designed to withstand the impact

Note 1 to entry: The VSB front face can be flat and perpendicular to the ground. In this case, the whole VSB front face is in line with the VSB datum line. In the case of a blocker, it is the furthest protrusion of the VSB structure designed to withstand the impact [see Figure 3 e)].

Note 2 to entry: The front face of the VSB is not the same as the front face of the VSB foundation or any supporting structure. In the case of a ditch, it is the point where the front face of the ditch meets the ground level.

Note 3 to entry: The VSB datum line is illustrated in Figure 3.
