Pull

Question 1

Pull over

while driving

Answer 1

When you’re driving, to “pull over” means to stop your car on the side of the road. Example: - When there’s an ambulance or fire truck approaching, you’re supposed to pull over to the side of the road and let them pass.

Example II: - You’re driving somewhere with your son riding in the back seat. He’s misbehaving, and you want him to stop. You threaten to punish him like this: “Don’t make me pull this car over!”

Question 2

Pull in/out 
Pull out (of a driveway or parking spot)

Answer 2

When you park a car, you “pull in” to the parking space or driveway. When you’re leaving the parking space, you “pull out” of it. Example: You’re teaching your teenage son to drive. You’re in your driveway now, and you give him instructions on what to do first:
- “Before you pull out, check in your rear view mirror to see if there’s anyone behind the car”.

You can use this phrase to talk about cars entering a road from some other road, parking lot, or driveway. For example: “Can you believe that guy pulling out in front of me like that? What the hell!”

Question 3

Pull up (a file on a computer)

Answer 3

When you’re using a computer or mobile phone, “pulling up” a file means opening it.
- “Can you pull up the pricing estimate I sent out last week?”.

You can pull up: a photo, a web page, a spreadsheet, a document, an email

However, “pull up” is probably not correct for talking about opening a music file or a game.
