If you're planning a road trip to Europe this summer, make sure you're not caught out by local laws that could land you with fines of up to £2,560. Each European country has its own legal requirements for what drivers must carry in their vehicles and being unaware of these could cost you a lot. According to Ed Sharp, Head of Car Hire at TravelSupermarket, checking your rental vehicle is properly equipped before hitting the road is crucial.

Not having a motorway toll sticker, for example, could cost you up £2,560 in various countries like Austria, Switzerland, Slovenia, Czechia and Slovakia. These can be bought before entering toll roads and though some rental companies include these in the hire agreement, this is not always the case so make sure you check with your provider before taking the wheel. 

In most European countries, you'll need a warning triangle and failing to have one could lead to some big fines. 

In serious cases, failing to carry a warning triangle or a reflective safety vest could result in fines of up to £640 in France, according to the French government website.

If you wear prescription glasses, you may also be legally required to carry an spare pair while driving in some countries.

Legal in several countries and always a smart idea, a first-aid kit must meet specific local standards.

In Germany, for instance, it must comply with the DIN 13164 regulation.

Pre-packed kits are available and typically include essentials like bandages, antiseptic wipes, gloves, scissors, and emergency blankets.

Before hitting the road this summer, double-check the rules in each country you're visiting to stay compliant with local driving laws.

Failing to meet these requirements could lead to hefty fines or even make your vehicle unroadworthy.
