In all conditions
Before any long journey, take a few minutes to check the tread and pressure of your tires (the required minimum tread depth is 1.6mm).
It’s also sensible to keep an emergency kit in your car just in case. These often contain things like a high-visibility vest, jump leads and basic first-aid supplies. Everyday items like water, a blanket, phone charger and paper towels are also useful.
Some countries ask you to carry certain items by law – like first-aid kits and warning triangles – so check before you set off.
