In Brazil, where lane numbers have been signed (at least where I have seen
such signs), the numbering follows the direction you read, i.e. from left
to right. Left most lane is 1, and rightmost lane is n. For example when
leaving Vitoria, passing the bus station the road is 8 lane for a short
bit, with signs saying "lane 1, 2 to 5th bridge, lane 3, 4 to bus station
and return to centro, lane 5, 6 to 1st bridge, lane 7, 8 to some suburb".
Maybe lane numbering is country specific, I don't know.
