Use our free online bus speed checker to see exactly how fast your bus is going: city bus, express coach or motorway service. No app, no download needed.
Tap Start GPS and allow location access
To check the speed of a bus right now, open this page on your phone, tap Start GPS and allow location access. The speed meter shows the live speed of the bus in km/h or mph and updates every second, so you see exactly how fast the bus is running at that moment, not an estimate.
This bus speed test runs in your browser, so there is nothing to install and no sign-up. It works on Android and iPhone, on city buses, AC buses, Volvo coaches, sleeper buses and school buses. Once the page has loaded, GPS keeps working even when your mobile data drops between towns.

To run a bus speed test, tap Start GPS above and allow location access. Your phone reads its position from satellites and this page turns that into a live speed reading in km/h or mph, usually within a few seconds of boarding. It works the same on a city bus, a school bus or a long-distance coach, and needs no app.
Buses are one of the most common forms of public transport, yet passengers rarely know the exact speed the vehicle is travelling at. Whether you're on a city bus, an express coach, or a long-distance motorway service, this free bus speed checker gives you a real-time GPS speed reading straight from your smartphone.
The tool works by reading your device's GPS receiver, which calculates speed from successive satellite position fixes. As a GPS speedometer for buses, it usually has a clear path to the sky through the windows, giving accurate readings in most urban and rural environments.
City buses typically cruise at 20–50 km/h due to traffic, stops, and speed limits. On a motorway coach or express service, expect to see 90–120 km/h. The peak speed display is especially useful on coaches where you want to know the maximum speed reached during a journey.
Tall buildings in city centres can cause "multipath" GPS errors, where signals bounce off facades before reaching your phone. This can cause the displayed speed to briefly spike or dip. The effect is minor and the average reading remains accurate over time.
Many countries require buses and coaches above a certain size to be fitted with a speed limiter, commonly capped around 100 km/h (62 mph), regardless of the posted speed limit on the road. This is a safety and insurance requirement tied to the vehicle's weight and passenger capacity rather than a choice made by the driver. If your GPS reading on a motorway coach plateaus just under that mark even on a derestricted road, the limiter, not GPS error, is almost certainly the reason.
Yes. This bus speed checker works as long as you have a window seat with a reasonable view of the sky: GPS signal will be strong enough for accurate readings throughout the journey.
Buses stop frequently, accelerate quickly, and travel through urban canyons where tall buildings reflect GPS signals. These factors cause small fluctuations which are normal.
City buses are typically limited to 60–80 km/h. Express and motorway coaches travel at 100–120 km/h.
Yes, particularly on the upper deck which has a better sky view, resulting in stronger GPS signal and more accurate readings.
GPS gives a good indication of ground speed, but should not be used as legal evidence. Official speed measurement requires calibrated equipment operated by authorities.
Most coaches and large buses are fitted with a speed limiter required by regulation, commonly capped around 100 km/h regardless of the posted limit. A reading that plateaus near that figure reflects the limiter, not a tracking error.
