The photo shows how one is forced to drive onto the sidewalk (albeit not very far)
to get close to the crane.
This can pose a risk during unloading, i.e., walls that could tip over due to the slope.
If you, as the driver, believe that unloading poses a risk, it is your right
and obligation to refuse to unload.
In any case, it is important to secure the walls in the risk zone separately.
