Danger signs are posted in built-up areas generally
close to the place of danger.
Outside built-up they are usually posted 150-250m
in front of the spot of danger.
If general distances should not apply, this will be indicated
with an additional sign. The note can be attached for distance (see nr.1),or
length of the hazard.(see nr.2)
Danger signs are always placed where even an attentive driver
can not recognize the danger in time.
Most of the times, speed must be reduced and one must be
ready to break.
