What should you do when facing a structure, post or closed area, while driving on a one-way roadway?

1. On an urban road - from either its right or left side; on a highway – always from its right side.
2. You should pass the place from its left side
3. You should pass the place from its right side only
4. Correct answer: You are permitted to pass the place from either its right or left side, unless otherwise marked

WhyOn a one-way road you may pass an obstacle on the right or the left unless marked otherwise. No one is coming the other way anyway.
