The estimated course lines target
flat surfaced objects (such as the
road). It is not possible to determine
the position of three-dimensional
objects (such as vehicles) using the
estimated course lines and dis-
tance guide lines. When approach-
ing a three-dimensional object that
extends outward (such as the flat-
bed of a truck), be careful of the fol-
lowing.
■ Estimated course lines
Visually check the surroundings
and the area behind the vehicle. In
the case shown below, the truck
appears to be outside of the esti-
mated course lines and the vehicle
does not look as if it hits the truck.
However, the rear body of the truck
may actually cross over the esti-
mated course lines. In reality if you
back up as guided by the estimated
course lines, the vehicle may hit the
truck.
