Changes

In rural areas hitchhiking is easier. Trucks have no problem stopping for you. Using a sign with "Xin Xe" followed by your destination works well. Expect every bus to stop as well, even if you don't have your hand stretched out. Most of the time they will charge, but you may get a free ride. Ask before entering by saying "Miễn Phí?" ("free?"). The Vietnamese can be very generous.

There is a substantial problem with police corruption. This is usually no problem for hitchhikers. However your driver may request that you pay the "fine". Drink driving is also common. It is up to the hitcher to use their discretion in these situations.
