could someone pls give me a proper explantion for policy and procedures---i need to write a paper on a case and use these terms but i don't know the explantions....thank you so much

Procedures is how something is done.

Policy sets up guidelines that the procedures are supposed to carry out.

Policy: Everyone will get fair treatment at a traffic stop.

Procedures:
No stops based on racial, gender, or age of the car occupants.
Citations will be issued on a basis not relating to person, and will be audited for that.
etc.
