Taiwan's long-distance highway transportation services are operated by private transportation companies: Kuo-Kuang Bus Corp., UBus, Free Go Bus Corp., and Aloha Bus, among others. They carry passengers on major highways and freeways.
Some bus companies provide 24-hour service, plus offer lower ticket fares than airplanes and trains, and are some of the most popular transportation service providers. However, for safety reasons, travelers are warned not to take illegal highway buses operated by companies without licenses.
Several bus companies provide daily transportation services between Taiwan Taoyuan International Airport and major cities.
The Taiwan Tourist Shuttle service is designed for convenient travel between train and high speed rail stations and major tourist attractions. It is an excellent option for people without a car.
