If you’re planning on driving in tough winter conditions, the first question you should ask is: is this journey necessary? Making a journey in your car that isn’t imperative or is one you could walk can sometimes be a risky action when the weather is adverse. If it is necessary and isn’t walk able, knowing what you might be facing is important. So check the weather reports for what’s incoming whilst you’re out and about, and if there are any road closures due to heavy snow.
Before setting off in earnest, check how much fuel is in the car and if it’s enough to not just get where you’re going and back, but also enough if you get stuck or have to go a longer route. Having your mobile phone fully charged is another factor that will need handling, as is having a map to hand if you have no sat nav or internet on your phone.
