Is it legal for a police officer to ask me to get out of the car?

Is it legal for an officer to ask you to step out of the car? Yes. If the traffic stop itself is a legal traffic stop, meaning they had a legitimate reason to pull you over to begin with, then absolutely yes, they are allowed to order you to come out of the car. The court has ruled several times that for officer safety, even if the officer has no specific suspicion that you are dangerous, they are allowed to legally ask you to step out of the car and they don't need a separate reason other than that traffic stop to ask you to get out of the car. Now remember, being asked to step out of the car doesn't necessarily mean that you're under arrest. It doesn't mean that gives them permission to search your car. It's usually just considered a minimal intrusion for safety reasons.
