(2) "Procession" means a group of individuals, vehicles, animals and/or objects moving along a street in a way that interferes with the normal movement of traffic. A procession shall not include a funeral caravan or military convoy.
(b) No person shall hold or participate in any assemblage unless the person organizing or conducting the assemblage first obtains a permit therefor from the Mayor, which shall be issued without fee. Application for the permit shall be made at least one week in advance of the day on which the assemblage is proposed to be held, but in any case where a State-designated highway is proposed to be used, application shall be made at least three weeks in advance of the proposed date. The permit shall state the place where and the date when the assemblage is to be held, the hour when the assemblage may convene and the hour by which it shall have been completely dispersed. No person shall hold or participate in any assemblage unless a permit therefor has been granted, or at any time or place other than that authorized by the permit.

Application for the permit shall be made at least two weeks in advance of the day when the procession is proposed to be held, but in any case where a State-designated highway is proposed to be used, application shall be made at least three weeks in advance of the proposed date. The permit shall specify the date on which the procession is to be held, the route to be followed by the procession, the hour when and the place where participants may commence to assemble and form before the procession is under way, the time when the procession may commence to move along its route, and the time when the procession is to end and its participants are to disband. No person shall hold or participate in any procession unless a permit therefor has been granted, or under any conditions as to time, route or otherwise than those stated in the permit.
