DC Gun Laws & Firearms Safety Practice Exam 2026 - Free Firearms Safety Practice Questions and Study Guide

When applying for a concealed carry permit in D.C., it is necessary to provide a firearm safety training certificate. This is because the District of Columbia requires that individuals seeking a concealed carry permit must have completed a certified firearms safety training course. The other options listed are incorrect because a voter registration card does not pertain to eligibility for a concealed carry permit, a recommendation letter from local police is not a requirement for the application, and although proof of residency may be necessary for the application process, it is not the specific document required for a concealed carry permit. Therefore, the correct answer is B Firearm safety training certificate.
