Are regular decision admissions at colleges binding?

I'm still exploring my college options and want to make sure I'm not tied down. When I apply through regular decision, am I committed to attending if accepted or can I still choose?

No, regular decision applications are not binding. Once you submit a regular decision application, you are under no obligation to attend that college if accepted. You have until the National Decision Day, which is typically May 1st, to make your choice among all the colleges that have accepted your application. You'll also have time to review and compare financial aid offers that can influence your college choice.

However, Early Decision (ED) applications are binding - if you get accepted to a college through ED, you're expected to enroll unless the financial aid offer provided by the college makes it financially impossible for you to attend. But since you mentioned applying through regular decision, this does not apply to you. That's one of the reasons many students prefer regular decision application, because of the flexibility it offers in terms of college choice.
