1. Charging for lifts – or even free lifts and car shares sometimes
We all know how organized lifts can positively impact our driving expenses. Whether you are traveling to work, a football game or even to school it can be a life (and cash) saver sometimes, but it also can be bad for your insurance. Some insurances, actually, exclude car sharing, whether you make a profit or not. Others that allow this, might get invalidated if you make a profit from giving lifts. To be fully disclosed, there are those policies that allow petrol money and driving costs sharing, you just have to read them thoroughly and be careful.
Always read the small print. Therein lies the devil!
