The Clarksville Police Department is limiting the number of vehicles in funeral processions to six.

According to The Leaf-Chronicle, a policy change this week specifies that any procession led by a city police officer will have a clearly marked final vehicle.

Mourners driving behind the final officer’s car must obey traffic signals and are not considered part of the procession.

According to Police Chief Al Ansley, off-duty officers can be hired as escorts for longer processions and there are also private companies that provide escort services for funerals.
