Vietnam, do they even have rules of the road?
To answer the question above, no, frankly they don’t have any appreciable road traffic rules at all. The traffic is heavy and it comes at you from every direction. Actually I lie, there is one rule. You ALWAYS give-way to the largest vehicle. Even if you are already on a roundabout doing your lawful thing just like the highway code taught you, if you see a car or worse a truck approaching the roundabout, you give-way. Because he is for sure going to pull on to the roundabout straight in front of you.
