Smoking
It is illegal to smoke in a vehicle that is used for driving tuition[1] even if there is not a pupil in the vehicle or you are using the vehicle on 
a family holiday. It also affects the resale value of your vehicle as well. You may not realise how much the smell of stale smoke lingers in the vehicle. There is a move at the moment to ban smoking at the wheel of any vehicle by any driver.
You must also display a no smoking sticker in your vehicle by law. The examiner will look for it on tests.
[1] The new smoke-free law will require company vehicles to be smoke free at all times if they are used: to transport members of the public or in the course of paid or voluntary work by more than one person – regardless of whether they are in the vehicle at the same time.
