Motorcycle taxis are a common form of public transport in Bangkok and most other cities, towns, and villages in Thailand. They are generally used for short trips. In Bangkok, there are motorcycle taxi queues on many sois, or side streets, and the queues are regulated by the city's government. Licensed motorcycle taxi operators wear vests. In compliance with Thailand's helmet law, many (but not all) drivers carry a spare helmet to offer to passengers. Bangkok locals generally only use motorcycle taxis when they need to get somewhere fast, as metered taxi-cabs are actually cheaper (but slower) than flat-rate motorcycles. Therefore, motorcycle taxi-drivers in Bangkok have built their reputation on delivering service as quickly as possible and tend to drive very fast and weave through traffic.
