Prepositions with Transport: In, On & At
Level A2 · Prepositions
English uses different prepositions for getting into or being inside different kinds of transport, based mainly on whether you can stand up and move around inside the vehicle. in is for small, enclosed vehicles you sit inside without much room to move (a car, a taxi). on is for larger vehicles you can walk around inside or that you sit 'on top of' in some sense (a bus, a train, a plane, a bike). at marks a location connected with transport (a stop, a station), not the vehicle itself.
How to choose in, on, or at with transport:
- in + a car, a taxi: We drove in a taxi to the airport; She got in the car and left. These are small, private vehicles you climb into and sit inside with limited space.
- on + larger public vehicles (a bus, a train, a plane, a ship, the underground/subway) and vehicles you sit astride (a bike, a motorbike, a horse). I read a book on the train; He was on the bus when it happened; She goes to work on a bicycle.
- get in/out of a car (small vehicle) vs get on/off a bus, train, or plane (larger vehicle) — the verb changes to match the preposition: Get in the car, please vs Get on the bus before it leaves.
- at marks a transport-related location, not the vehicle: We waited at the bus stop; They met at the station — at is for the place, on/in is for being inside the vehicle itself.
The most common mistake is using in with large public vehicles — in the bus, in the train, in the plane sound unnatural; use on: on the bus, on the train, on the plane. A second mistake is confusing at (a location) with in/on (the vehicle) — I was in the bus stop is wrong; a stop or station is a place, so it takes at: I was at the bus stop.
Ask whether you're referring to a small private vehicle (in), a larger public vehicle or something you sit astride (on), or a transport-related location like a stop or station (at). If you can walk around inside it or sit on top of it, use on; if it's small and enclosed, use in; if it's a place connected to transport rather than the vehicle, use at.
