Since the successful isolation of graphene in 2004, bilayer graphene (BLG) has emerged as one of the most extensively studied multilayer graphene systems. The transport properties of BLG and N-layer bilayer graphene structures have typically been investigated in the high-carrier-density regime using the random phase approximation (RPA). In this work, we focus on the low-density regime and calculate the carrier-density-dependent conductivity σ(n) of three-layer bilayer graphene (3BLG) systems, taking into account charged impurity scattering with spatial correlations. In this regime, electron–electron exchange effects must be considered. Therefore, employing a semiclassical Boltzmann transport theory within both the RPA and the Hubbard approximation (HA), we study the conductivities of the first and second layers, 
and 
, as functions of the impurity correlation length 
. The results presented in this work provide further insight into the role of electron–electron exchange effects on σ(n) in 3BLG structures.
