In Reply to: map of street driving directions posted by Bintang Girl on Tuesday, 15. June 2010 at 20:19 Bali Time:
either officially or unofficially one way for cars only.
Motor bikes generally go both ways, especially on "minor roads" and lanes.
A map will probably just show the direction required of cars.
You are probably best to follow the locals and slowly you will familiarise yourself with all the small gangs and short cuts that the local bike riders use.
