Maryland Transportation Section 21-207

      (a)      Notwithstanding any other provision of this title, a funeral procession facing a red signal may continue through or make a turn at an intersection if the first vehicle in the procession already entered the intersection before the signal changed from green to red.

      (b)      While a funeral procession is proceeding through a red signal as permitted by this section, a vehicle that is not in the procession may not enter the intersection, even if it is facing a green signal, unless it can do so without crossing the path of the procession. When the red signal changes to green while the funeral procession is still within the intersection, a vehicle facing a green signal may proceed, but the funeral procession has the right-of-way.

      (c)      The driver of a vehicle in a funeral procession does not have any privilege granted in this section unless:

            (1)      The headlights of the vehicle are turned on; and

            (2)      Subject to § 22-221(g) of this article, the warning lamps of the vehicle are flashing.
