Understanding the correct preposition to use with different modes of transportation can be tricky.

Whether you’re hopping on a bus, boarding a train, or catching a flight, the choice between “on” and “in” can make a significant difference in clarity. 

This guide will help you master these prepositions, with clear explanations, practical examples, and helpful exercises to solidify your understanding.

Understanding Prepositions of Transportation

Prepositions are essential in English, as they help us describe the relationship between different elements in a sentence. When it comes to transportation, the choice of preposition—“on” or “in”—depends on several factors, including the type of vehicle and its size.

Prepositions of transportation are used to describe our position relative to various modes of travel. Here’s a quick overview of their roles:

• “On”: Generally used for larger vehicles where you are a part of the transportation system.
• “In”: Typically used for smaller vehicles where you are enclosed within a space.

General Rules

• Use “on” for vehicles that are perceived as large or long, where you are more like a passenger within a system.
• Use “in” for vehicles that are smaller or enclosed, where you are physically inside a limited space.

“On The Bus”

Rule Explanation

When talking about being on a bus, train, or plane, we use “on”. This usage is rooted in the historical context where people were metaphorically “on board” a mode of transport. It implies that you are part of a larger, moving system.

Historical Context: In the past, the term “on board” was used for ships and later extended to other forms of transportation. This practice continues today, even though the means of transport have changed.

General Usage

The preposition “on” is used to describe your presence as part of a larger vehicle. Here are a few general rules:

• Public Transportation: Buses, trains, and planes are considered large enough to use “on” because they can carry many passengers.
• Open Vehicles: Vehicles like bikes or boats are also described with “on” because they are part of a larger system.

Examples

• Correct Usage: “I am on the bus heading downtown.”
• Comparative Example: “She is on the train to New York.”

Common Mistakes

A frequent mistake is using “in” instead of “on” with larger vehicles. For example, saying “I am in the bus” is incorrect. The right usage is “I am on the bus.”

“In The Bus”

Rule Explanation

“In” is used when referring to the interior of the bus or similar vehicles. This preposition emphasizes that you are inside an enclosed space.

Specific Contexts

When you talk about objects or people inside the bus, “in” is appropriate. For instance, if you left something on the bus or you are describing the interior of the bus, you use “in.”

Examples

• Correct Usage: “I left my book in the bus.”
• Comparative Example: “She found her phone in the taxi.”

Common Mistakes

A common error is saying “on the bus” when referring to objects inside it. For example, “I found my keys in the bus” is correct, not “on the bus.”

Other Modes of Transportation

Understanding how “on” and “in” apply to different types of vehicles helps clarify their usage. Let’s break it down:

Trains

• On the Train: Used for general travel or being a passenger. “He is on the train to Chicago.”
• In the Train: Less common but used when talking about being inside a specific compartment. “She is in the dining car of the train.”

Planes

• On the Plane: Used for being a passenger. “They are on the plane to Paris.”
• In the Plane: Can be used when discussing being within a specific area inside the plane. “He left his bag in the plane’s overhead compartment.”

Cars

• In the Car: Always used for cars. “I am in the car with my friends.”

Regional Variations

Preposition usage can vary based on regional dialects:

British vs. American English

• British English: Often uses “on” with some forms of transportation, such as “on the bus” or “on the train.”
• American English: Follows similar rules but might use “in” more frequently for specific contexts.

Examples

• British English: “I am on the tube.”
• American English: “I am in the car.”
