Biofuel is a renewable fuel typically made from food crops, wood waste, or, as in New Zealand, from dairy industry by-products. Biofuel can either be petrol blended with a maximum of 10% bioethanol, or diesel blended with a maximum 5% biodiesel.
Biofuel benefits the environment because it burns more cleanly and reduces the amount of carbon dioxide (greenhouse gas emissions) produced by your car.
An electric vehicle, or EV, has a different engine to a petrol or diesel fuelled car – it has a motor that is powered by a battery which is charged by plugging it into an electric power point (a bit like charging your cellphone battery).
The official New Zealand road code for heavy vehicle drivers is a user-friendly guide to New Zealand's traffic law and safe driving practices. You will be tested on this information in your theory and practical driving tests.
