Road damage caused by heavy vehicles is a serious problem experienced worldwide. This paper investigates the
potential for reduction in road damage by incorporating the inerter element into truck suspension systems. Initially,
quarter-car, pitch-plane and roll-plane models with two low-complexity inerter-based linear suspension layouts are investigated in the frequency domain. Reductions of the J95 road damage index for each model are identified against conventional parallel spring-damper truck suspension layouts. It is also shown that proposed suspensions are capable
to enhance the roll stability while keeping the road damage at a given level. Subsequently, the nonlinear relationship
between force and displacement as manifested by leaf springs is incorporated into the pitch-plane and roll-plane time
