Warming up the engine: why is it banned in some countries?
Winter, frosty mornings, frosted windows are a familiar picture for most motorists. The first thing that comes to mind is to start the engine and let it warm up while you clear snow or drink coffee. But in some countries this usual procedure can result in a fine. Why?
It's all about environmental standards and the fight for clean air. Idling is one of the most harmful modes of engine operation: in 10 minutes of warming up, the same amount of CO₂ is released into the atmosphere as when driving 5–8 km. In cities with high traffic density, this becomes a serious problem. For example, in European Union Since 2020, emissions requirements have become stricter, and some countries have gone even further - completely banning warm-up in parking lots.
But there are also exceptions. In regions with extremely low temperatures (such as Scandinavia or Canada) local authorities turn a blind eye to short-term warm-up - otherwise the engines simply won’t start. But in warm countries, where frosts are rare, fines for “extra” emissions can reach hundreds of euros.
Top 5 countries where warming up the car is prohibited by law
If you're planning to travel abroad during the winter, be sure to check local regulations. In some states, fines for idling warm up can ruin your entire vacation. Here is a list of the strictest countries:
- 🇩🇪 Germany - fine from €20 to €100 (depending on the region). Exception: temperature below −5°C.
- 🇫🇷 France — the ban applies in Paris and other major cities. Fine: up to €135.
- 🇬🇧 UK – fine £20–£80 (about €23–€92). The rule is effective from 2022.
- 🇳🇱 Netherlands — prohibition on warming up for more than 3 minutes. Fine: €95.
- 🇨🇭 Switzerland - one of the strictest laws: a fine of up to 250 CHF (€260).
It's interesting that in Austria and Belgium the ban applies only in certain areas (usually city centers), and in Italy - only at temperatures above 0°C. B USA rules vary by state: e.g. California The fine for warming up can reach $1,000, and in Texas or Alaska there are no such restrictions.
How do exceptions work: when is warm-up allowed?
Even the most environmentally strict countries have loopholes for motorists. The main thing is to know the nuances of local legislation. For example:
- ❄️ Temperature threshold. In many EU countries, heating is allowed if the temperature is below −5°C (in Finland - below −10°C).
- ⏱️ Warm-up time. B Denmark You can warm up the engine for no longer than 5 minutes, in Norway — 10 minutes at −15°C.
- 🚗 Vehicle type. B Sweden an exception is made for diesel cars and trucks.
- 🏥 Special transport. Ambulances, police and utility services are generally exempt.
B Canada and northern states USA (for example, Minnesota or Michigan) there is an unspoken rule: if the car does not start without warming up, there will be no fine. But in Japan even at −10°C you will have to do without long idling - there priority is given to electric vehicles.
What happens if you ignore the ban?
In most European countries, fines are recorded by cameras or environmental inspectors. For example, in Germany, data about a violation may be transferred to the insurance company, which will affect the cost of the policy. In Switzerland, if a violation is repeated, your license may be confiscated for 1–3 months.
Fines for warming up the car: comparison table
To avoid getting into an unpleasant situation, study the fines in countries popular with tourists. The table below shows current data for 2026:
| Country | Fine (EUR) | Exceptions | Who controls? |
|---|---|---|---|
| Germany | 20–100 | Temperature below −5°C | Police, environmental activists |
| France (Paris) | up to 135 | Electric cars, hybrids | Municipal police |
| Switzerland | up to 260 | Mountainous regions (below −10°C) | Environmental inspection |
| Netherlands | 95 | Warm up to 3 minutes | Automatic cameras |
| Denmark | up to 70 | Temperature below −7°C | Police, neighbors (you can complain) |
Important: in some countries (for example, Austria) fines can be cumulative. If you are caught warming up several times during the winter, the total amount could exceed €500.
How to warm up your car legally: life hacks for travelers
If you're traveling to a country with a warm-up ban, but don't want to risk your engine, use these tips:
- Use autostart from key fob. In most countries it is only prohibited idling without driver. If you are sitting in a car, this is not a violation.
- Install preheater (for example, Webasto or Eberspächer). It warms the coolant, not the engine at idle.
- Park in a garage or underground parking lot. Even +5°C in the garage will save you from icing up the windows.
- Use electric heating. B Norway and Sweden Parking lots often have outlets for connecting heaters.
B Finland and Estonia popular remote start units with a timer. They allow you to start the car 10–15 minutes before your trip, but only if you are nearby (for example, in a cafe or office).

What to do if you are fined for warming up?
If you do receive a fine, do not rush to pay it. In some countries you can challenge the decision:
- 📄 Check the protocol. The inspector had to record the air temperature and warm-up time. If this data is not available, the fine can be appealed.
- 📱 Make a video. A dash cam recording showing the thermometer in the car (for example, -6°C) can be used as evidence.
- 💳 Pay with a discount. In many countries (for example, Germany) the fine can be paid with a 50% discount within 7 days.
B Switzerland and Austria when appealing, they often require an expert opinion on the need for warming up for a specific car model. For example, for diesel engines with the system DPF (particulate filter) prolonged idling can be disastrous - this is an argument in your favor.
⚠️ Attention: In some countries (for example, France) Fines for environmental violations may affect your ability to rent a car in the future. Data about violations are stored in the database EU Car Rental Agreement.
Myths about engine warming up: what's true and what's not?
There are many myths surrounding the topic of warming up. Let's look at the most popular:
- ❌ "Warming is only needed in winter" → Not true. In summer, short-term idling is useful for lubricating the turbine (if there is one).
- ✅ "Modern engines do not need to be warmed up" → True, but only for gasoline engines with a system
direct injection. Diesels and older carburetor cars require warming up. - ❌ "Warming up at idle is more harmful than driving" → Depends on conditions. At −20°C, a sudden start without warming up can damage timing belt or turbine.
- ✅ "In some countries they fine you for even 1 minute of warming up" → True. For example, in Luxembourg Any idling for more than 60 seconds is prohibited.
Experts ADAC (German Automobile Club) recommend following the rule "30 seconds in summer, 2–3 minutes in winter". But even this may be a violation in countries with strict environmental regulations.
If you rent a car abroad, be sure to check with the rental company about the warm-up rules. In some companies (for example, Sixt or Europcar) the contract states that the client himself is responsible for environmental fines.
