Vinasun taxi by Ovidius 1313

Drivers generally speak limited English and do not speak any other foreign languages, so it's wise to write the name and address of your destination, preferably in Vietnamese, to show the taxi driver - your hotel staff can assist. It also helps to carry one of your hotel's business cards so you can return to the hotel without too much fuss. Carry small change and bills for paying fares, since drivers are often short of change. 

Taxi drivers are likely to drive too fast when given the chance. Ho Chi Minh City has a unique traffic pattern in which cars and buses drive in the centre lanes on two-way streets, or the left lanes on one-way streets, while the outside or right lanes are reserved for motorcycles. Rush-hour traffic in the city has become so bad that you might consider just planning not to go anywhere between the hours of 7:00-8:30 a.m. and 4:30-6:00 p.m.
