I’ve always been confused by prepositions of transport. Why is it that we say “in the car” but “on the bus”? Is there a specific logic behind using “on” for larger vehicles and “in” for smaller ones, or is it just something I have to memorize as an exception?

Dear Lila,
As an English teacher, I can tell you that while prepositions often feel random, there is actually a very logical "spatial" rule for transportation. You don't have to memorize them as exceptions!
The distinction usually comes down to whether you can walk or stand inside the vehicle.
1. Use "ON" for a Platform
We use "on" for vehicles that have a "floor" or a "deck" where you can stand up and walk to your seat. Think of these as public or large-scale transport.
The Logic: If there is an aisle (a walkway), you are "on" that floor.
Examples: On a bus, on a train, on a plane, on a ship, on a subway.
2. Use "IN" for Enclosed Spaces
We use "in" for smaller, private vehicles where you have to crouch to enter and you must sit down immediately. You are essentially "inside" a small box.
The Logic: You cannot stand up or walk around; you are contained within the seating area.
Examples: In a car, in a taxi, in a truck, in a helicopter.
Hope this helps! ❤
So detailed, thank you!
Good question — there is some logic to it. We usually say “in” for private/smaller vehicles (in the car, in a taxi) because you’re enclosed inside. “On” is used for public or larger transport (on the bus, on the train, on a plane) where you’re more like a passenger on board. Platforms like KotoEnglish explain these patterns through real situations, which makes them easier to remember than just memorizing rules.
useful answer, thank you
