If the police stop you, they won’t just want to make sure you have a high-visibility vest. Another piece of compulsory equipment they may check is your first aid kit, and you should bear in mind that these kits have a limited shelf life. Fines for a first aid kit past its expiry vary from market to market. In the Czech Republic, for example, it can be as much as CZK 2,000 (EUR 80). When you do your spring check, make sure to add the first aid kit expiry date to your checklist to be on the safe side.
