Crossing the road in Vietnam
The streets of Vietnam, especially in big cities like Ho Chi Minh City and Hanoi, always crowded with motorbikes and cars. Many foreigners do not dare to cross the street when they see too many transportation vehicles on the road, especially motorcycles. The basic technique to crossing the road is calm down and moves forward slowly. You should not move too fast or to step back suddenly. If you cannot cross the street alone, don’t hesitate to ask a local person to take you or wait others and go with a small group - it will be easier and safer for you.
