In Vietnam, moto-bikes are very common. It is not unlikely to see a family of five squeezed onto one bike. Needless to say, seat belt laws are not as strictly enforced in Vietnam as they are in the United States.
Another difference in driving laws between the United States and Vietnam is how a pedestrian crosses the street. In the U.S., pedestrians wait until the crosswalk says “walk.” In Vietnam a pedestrian simply begins crossing the street; it is important to maintain the same speed while crossing since moto-bikes will dodge you as you cross.
Obtaining an international drivers permit (IDP) is important for driving while you are abroad. The IDP allows you to legally drive while in another country if you have a valid driver’s license from your state. IDP’s are issued by the American Automobile Association. You must be 18 years old to acquire one.
The U.S. Department of State offers country specific information about driving laws in other countries in their travel section. It is important to review these laws before traveling abroad.
