The maximum speed of a bus varies widely depending on its type, purpose, and where it operates:
- Standard city/transit buses typically have top speeds of 50-70 mph (80-112 km/h), though they rarely reach these speeds in urban environments
- Highway coaches/intercity buses are often designed for higher speeds, typically 65-80 mph (105-130 km/h)
- School buses in the US generally have speed limiters set between 60-72 mph (97-116 km/h)
- Double-decker tour buses usually have top speeds similar to city buses
- Modern electric buses typically have top speeds of 50-65 mph (80-105 km/h)
Many commercial buses have speed governors or limiters installed for safety and fuel efficiency. Local regulations also often restrict bus speeds, especially for public transit and school buses.
