Turn restrictions are
OpenStreetMap's way of telling you where you aren't allowed to go or where you have to go when you're at a junction and there's no other kind of restriction like oneway or
access. We have two different main kinds of turn restrictions:
only-restrictions and
no-restrictions.
Icons
only-restrictions are
only_right_turn
only_left_turn
only_straight_on
no-restrictions are
no_right_turn
no_left_turn
no_straight_on
no_u_turn
no_entry
no_exit
special icons on this map
turn restriction with errors
turn restriction with warnings (yellow arrow)
turn restriction with warnings (yellow background)
Member highlight colours
When hovering over a turn restriction the members of this turn restriction are drawn. Here are some examples to explain the different colours:
only-restrictions:
Moving along the
from-way to the
via-node (or the
via-way) you are
only allowed to continue on the
to-way.
no-restrictions:
Moving along the
from-way to the
via-node (or the
via-way) you are
not allowed to continue on the
to-way.
restrictions with errors:
Ways and nodes of turn restrictions with errors are drawn the same way as without error.
But sometimes there's a restriction member without role or with an unknown role.
We don't know whether it belongs to
from,
via or
to.
These members are drawn in
yellow.
A note on the reported errors and warnings
Please keep in mind: Errors or warnings shown on this map are not necessarily caused by errors of the turn restriction. Maybe the tagging of the ways is invalid or maybe this map doesn't work correctly. Also keep in mind that warnings are subjective according to my interpretation of turn restrictions - your rating may vary. There is no way of telling this map to ignore a warning on a specific turn restriction.
