BY When talking about general ways to travel, we always use the preposition “by.” We can travel by bike, by motorcycle, by car, etc. We can also use by to refer to the transportation environment (by sea, by land, by air) or the surface area (by rail, by road, by water).

IN When we talk about specific transport vehicles, however, we need to switch to either in or on. How do we know which to use? Easy, if you remember this simple rule: If you must sit inside the vehicle, we use in. Some examples would be: "in a car", "in a truck", or "in a helicopter": it is almost impossible to stand in them.

ON If you can stand or walk on the vehicle, then we use on. So we go on a ship but in a rowboat; we go on a bus but in a taxi. Finally, if we actually sit or stand upon the top of the vehicle, then we also are on it. So we go on a bicycle, on a surfboard, on a motorcycle, etc. The preposition in is different from the short form of inside. So, you can be inside an airplane or a cruise ship, but that doesn’t mean we use the preposition in (we can stand and walk on both a plane and ship, so we use on as our preposition).

ON and BY And, where does that leave the most basic form of transportation — walking? Well, the same rules apply: we go by foot (meaning as a general way of moving from one place to another) or we go on foot (meaning we are on top of our feet!). Therefore, both are correct ways to describe walking.

Transportation-the movement of people, animals and goods from one location to another Transportation is possible through air, land, and water
