OSM does not encode defaults in its database.<br>
There is a <a
href="https://wiki.openstreetmap.org/wiki/Proposed_features/Defaults">Proposed
features/Defaults</a>
, but instead of being validated or improved, it was abandoned.<br>
Defaults are encoded in external databases, one per routing engine.<br>

<div>Most complicated example I can think of is one intersection
I remember is at <a moz-do-not-send="true"

and it's immediately adjacent companion for the other
carriageway just south. U-turns are banned in Oregon at
traffic lights, but facing Canyon Road eastbound and westbound
is a sign that says "U Turn OK, CARS ONLY". Northbound and
southbound traffic cannot U-turn at the light. So there would
need to be an exception for motorcars coming from the east or
west to allow a U-turn and a statewide regional default to
deny U-turns at lights for all modes.</div>
