Taxis with meters, found in most major cities, are very cheap by international standards and a safe way to travel around at night. Average tariffs are about 12,000d to 15,000d per kilometre. However, dodgy taxis with go-fast meters do roam the streets of Hanoi and HCMC; they often hang around bus terminals. Only travel with reputable or recommended companies.
Two nationwide companies with excellent reputations are Mai Linh (www.mailinh.vn) and Vinasun (www.vinasuntaxi.com). Some hotels can help you to book a safe, competitively priced Grab (www.grab.com) car or xe om (motorbike taxi) through a smartphone app.
Few travellers deal with city buses due to communication issues and the cheapness of taxis, cyclos and xe om. That said, the bus systems in Hanoi and HCMC are not impossible to negotiate – get your hands on a bus map.
