A vehicular divider assembly includes a member that is positionable on a ceiling of a vehicle cabin. A divider is coupled to the member such that the divider extends between a forward compartment of the vehicle cabin and a rear compartment of the vehicle cabin. The divider is comprised of a fluid impermeable material to inhibit the transfer of microbes between the forward compartment and the rear compartment. A flap is integrated into the divider to facilitate air to move between the forward compartment and the rear compartment of the vehicle cabin. A pair of first mating members and a pair of second mating members is each coupled to the divider which can be secured to structural features of the vehicle cabin.
