嗯。。。。Your NCD can- Be transferred if you decide to switch insurer. Be transferred to another vehicle you own, but it cannot be applied to more than one vehicle at any point in time. For example, if you have accumulated a 30% NCD while using one vehicle, it does not follow that the same NCD applies to any other vehicle that you own or decide to buy. In other words, you will have to earn the NCD for each vehicle separately.
