Bullet proof vehicles (BPVs) are special purpose vehicles manufactured by carrying out modification of existing vehicle mostly inside compartment which contains basically hidden box of steel built inside the vehicle. Most critical areas of a bullet proof vehicle are protection of persons and maneuverability of the vehicle. Difficulties being faced in producing BPvs includes identification of suitable vehicle roll over models from the literature, parameters selection, comparison of these models and formulation of model new one exclusive to bullet proof vehicles produced in developing countries. This work presents an initial investigation to narrow down parameters selection to analyze roll over tendency in Bullet proof vehicles and offer a suitable methodology to avoid expected Bullet Proof Vehicle rollover due to dangerous driving maneuvers. Different scenarios are to be considered while roll model formulation of these special purpose bullet proof vehicles. Not only the add on armored protection drastically increase the weight of the vehicle which is the most critical area but also some special cases which are specific to BPV maneuverability also arises. The effect of such instable tendency on rollover require investigation not captured by existing normal vehicle models and further supports the idea for its investigation of roll over tendency. It has been learnt that uneven distribution of weight develops certain moments in a BPV which can create hidden instability tendency in a BPV.
