Lighting and visibility rules by country in Europe

Daytime running lights in Germany, fog lights when visibility is less than 50 metres, dipped headlights in every tunnel. The lighting rules differ from country to country. If you are travelling through Europe by car, you need to know in advance exactly when which lights are compulsory. This helps you avoid fines and ensures you drive safely. What is normal in the Netherlands can quickly cause confusion abroad.

Lighting rules may seem like a minor detail. However, you can run into trouble as soon as you cross the border if you do not switch in time from daytime running lights to dipped headlights. The rules are stricter than in the Netherlands, especially in Scandinavia and parts of Eastern Europe. The same goes for traffic regulations and driving abroad. Good preparation helps you travel safely and without worries.

This article explains which lighting rules apply in each country. You will find out when you have to switch from daytime running lights to dipped headlights. You will also read how to avoid incorrect use of fog lights or rear lights during your car journey abroad.

When do you have to use daytime running lights in Germany

In Germany daytime running lights are not compulsory, but they are allowed. In good weather and during daylight hours, daytime running lights are sufficient. Note: daytime running lights are not a substitute for dipped headlights. In poor visibility, rain or twilight you must switch to dipped headlights. Daytime running lights do not illuminate the road sufficiently. They also often do not switch on the rear lights.

Many modern cars switch over automatically. With hire cars or older vehicles you need to do this yourself. Always check whether your rear lights are on as soon as visibility worsens. Do this as well when dusk is falling.

What are the rules for lighting in tunnels

You are driving into a tunnel. In all European countries you are then obliged to use dipped headlights. This applies regardless of the time of day or the amount of daylight. Daytime running lights are not sufficient. They do not illuminate the road enough. They also often do not switch on the rear lights.

Many tunnels in Switzerland, Austria, France and Italy are fitted with cameras. These cameras check whether you have your lights on. Do you drive through a tunnel with only daytime running lights? Then you risk a fine. In Italy this can be as high as 80 euros.

About to enter a tunnel? First check whether your lights are set to dipped headlights. With automatic lights it is best to set the switch to the ‘dipped beam on’ position. That way you know for sure that the lights are on.

How do you adjust headlights for driving on the right

You are travelling by car from the Netherlands to another country. There you will be driving on the right. Check whether your headlights are correctly adjusted. Dutch headlights are set asymmetrically. This prevents dazzling oncoming traffic. When driving abroad this actually causes glare.

In many modern cars you can adjust the headlights manually. You do this with a switch in the car. You can also adjust them via the menu on the dashboard. Check this in your car’s manual. With older vehicles you attach special stickers to the headlights. These stickers adjust the beam of light. You can buy them at petrol stations and car accessory shops. They are available just before the border.

Are you driving a hire car? Then the headlights are usually nothing to worry about. Hire cars in the country itself are already set correctly for local traffic.

Overview of lighting rules by country

The lighting rules vary greatly from one destination to another. Below you will find an overview of the most important rules:

Scandinavia: dipped headlights always compulsory

In countries such as Norway, Sweden, Finland, Denmark and Iceland there is a strict rule. Dipped headlights are compulsory there all year round. This applies during the day. It also applies at night. The weather does not matter. Daytime running lights are only sufficient if your rear lights automatically come on as well.

Germany: daytime running lights or dipped headlights allowed

In Germany you drive during the day with daytime running lights. This is allowed in good visibility. In rain you must switch to dipped headlights. Dipped headlights are also necessary in fog or dusk. In tunnels dipped headlights are always compulsory.

France: dipped headlights in poor visibility

In France dipped headlights are compulsory in poor visibility. You must also use dipped headlights in tunnels. The obligation also applies at dusk. During the day in good weather, daytime running lights are sufficient. Fog lights are only allowed when visibility is under 50 metres.

Italy and Spain: dipped headlights outside built-up areas

In Italy and Spain dipped headlights are often compulsory outside built-up areas. This also applies during the day. The rule differs from region to region. The type of road also plays a role. Always check the local rules in advance. This is particularly important if you are travelling with a motorhome or trailer.

Austria and Switzerland: dipped headlights in tunnels

In Austria and Switzerland dipped headlights are compulsory in tunnels. You must also switch to dipped headlights in poor visibility. During the day in good weather you drive with daytime running lights. Note: in Swiss tunnels checks on correct lighting are very strict.

Pay extra attention with motorhomes and heavier vehicles

For motorhomes and cars with a trailer, stricter rules apply in some countries. This also applies to vehicles above a certain weight. In Poland, Hungary and Slovenia dipped headlights are compulsory for heavier vehicles. This also applies during the day. The weather does not matter.

Check in advance whether separate rules apply to your type of vehicle. This prevents unpleasant surprises during checks. It also makes your journey more relaxed.

Frequently asked questions

What specific ‘lighting rules’ apply to cars in the countries I am planning to visit, and what ‘compulsory equipment’ do I need to take with me for this?

During the day, using dipped headlights is compulsory in many Northern and Eastern European countries (including Norway, Sweden, Finland, Denmark, Estonia, Latvia, Lithuania, Italy, Poland, Slovenia and Hungary), even in good visibility; in the rest of Europe, daytime running lights are usually sufficient in good visibility. In the dark, in fog, snow, heavy rain and in tunnels you must always drive with dipped headlights (and lit rear lights) in all countries you visit; fog lights are only allowed in severely reduced visibility. Compulsory equipment in many countries includes, among others, high-visibility vests, warning triangle, first-aid kit, spare bulbs and sometimes a spare pair of glasses, although the exact requirements differ by country. Therefore, before departure, check for each individual country which specific daytime lighting obligations apply and which safety items are precisely compulsory.

Are there country-specific rules for the use of ‘daytime running lights’ or ‘fog lights’ that I need to be aware of for a safe trip?

Yes, there are country-specific rules for daytime running lights and fog lights, particularly in Scandinavia, the Baltic states and parts of Central and Eastern Europe, where using dipped headlights instead of just daytime running lights can be compulsory during the day. Fog lights and rear fog lights may almost everywhere only be used in genuinely poor visibility; unnecessary use can result in a fine. For a safe journey it is wise to check in advance for each country whether dipped headlights are compulsory during the day and what rules apply to fog lights. If in doubt, it is better to use dipped headlights than only daytime running lights, and switch fog lights off immediately once visibility improves.

What specific ‘visibility rules’ apply to drivers and passengers outside the vehicle, such as wearing a ‘high‑visibility vest’ in the event of a breakdown in the different countries?

The visibility rules for drivers and passengers outside the vehicle differ by country. In many countries (including various EU member states) wearing a reflective high‑visibility vest is compulsory as soon as, in the event of a breakdown or accident, you exit the car on or alongside the carriageway; often there must be a vest available for every occupant. Some countries require that the vests are kept within easy reach (not in the boot). Therefore, check in advance for each country whether high‑visibility vests are compulsory, for how many people and in which situations (for example only outside built-up areas or on motorways).

How do ‘weather conditions’ or ‘times of day’ affect the ‘lighting obligation’ in the countries on my route, and what ‘extra tips’ are there for ‘optimal visibility’?

In all countries on your route, lights are compulsory in the dark, and in bad weather (fog, heavy rain, snow) you often also need at least dipped headlights during the day, regardless of the time. In several countries (including Scandinavia, parts of the Baltic states and Central/Eastern Europe) dipped headlights may furthermore be compulsory during the day outside built‑up areas or during certain seasons. When in doubt, always drive with dipped headlights rather than only daytime running lights, and use fog lights only in genuinely restricted visibility. For optimal visibility: check that your rear lights are on as well, do not use dazzling fog lights in good visibility, and do not rely blindly on automatic lighting but adjust it manually in tunnels, at dusk and in mountainous terrain.
