For the most part, yes. First, the date on flour isn't really an expiration date, it's more of a "best by" date. This means the company is stating that after that date the flour may not perform the same or taste as good. However, if the flour appears and smells normal and you've stored it properly then it's likely ok to use. However, if you have any doubts or notice any visible signs of spoilage, it is better to discard the flour to avoid any potential health risks.
