A person who possesses a valid hunting license and who has a disability which impairs his mobility may receive a permit from the Department to hunt from a vehicle. However, the person may not shoot or have a loaded weapon in the vehicle while the vehicle is on a public roadway or the shoulder of a public roadway. To be issued a Universal Disability Pass a person shall: Submit a completed Department application to the DNR Licensing and Registration Service’s office in Annapolis; and Obtain a physician's signature on the application which certifies that the applicant is mobility impaired. Each permittee shall: Have the permit on his person while hunting; Keep the vehicle at a complete stop with the motor turned off while shooting, aiming, or firing the weapon; and Have all weapons unloaded, including no ammunition in the magazine, while the vehicle is in motion. A permittee may have other permittees and a companion in the permittee's vehicle while hunting. A hunter may serve as a companion but may not hunt from the vehicle. In addition to any other sanction provided by law, the Department may suspend or revoke the permit if the permittee violates any provision of this regulation.
