In US usage, which differs from UK usage. "On the street" usually refers to the location of a building. "I live on Main Street." It can also mean, literally, physically on top of the pavement, but this usage is somewhat less common "There was a puddle on the street." "In the street" means something is located within the boundaries, the edges, of the street. "The car was parked in the street."

They mean the same thing. Es lo mismo

That's a good question. It actually depends on the sentence and usage. The terms take on colloquial meanings. I'll try some examples: "The children were playing in the street." Describing the general area where an action is happening. "The children were spilling chocolate milk on the street" is a physical act which is affecting the street's condition or surface. Does that help? I don't believe there are specific rules as they are phrases that are used often colloquially. Here's an example of the same sentence using both phrases: "The men/women are working in the street." This refers to people changing the physical condition of the street. "The men/women are working in the street." This refers to people who are doing work in the area of the street but something other than working on the condition of the street. They could be working on a car that's on the street. Rick
