I’ll copy & paste if I can

 

There are subtle differences in each state's law. And there is the interpretation, and then the implementation, and last, but not the least, there is the understanding of the Authority Having Jurisdiction (that would be the nice policeman talking to you).

My personal recollection of playing it safe and moving over, though not required by law:

Northbound on I-69, from Indy, and there's a truck on the right shoulder. I move over to the fast lane, and as I pass the truck, the driver loses his footing while looking at the engine, and executes a right face, and lands with both feet in the traffic lane. Looked like an action figure, with his hands up in the air. His expression was more like "Oh Oh!" not so much as "ready for anything!",

I was grateful I moved over, even though I wasn't obligated.
