You shouldn't need to tag motorways as oneway because that is implied for a
motorway.

For other roads; trunk, primary, etc, you do need to tag each carriageway
with oneway=yes otherwise there is no way to tell.

FWIW there is no need to tag roundabouts as oneway either.  That is an
implied attribute of junction=roundabout.
