Insuring a second car in Germany: SF class, second-car rule and alternatives

Buying a second car for the household is the easy part. Insuring it raises one big question: which no-claims class (SF class) will the second car get? Without its own claim-free history, it could be rated like a brand-new driver's car – which is expensive. That is why many German insurers offer what is known as the Zweitwagenregelung, or second-car rule.

This guide explains how the rule works, what insurers typically require and which alternatives are worth knowing about.

Is second-car insurance a special product?

Not really. A "second-car policy" is a normal German car insurance policy for an additional vehicle in your household. The second car needs its own mandatory liability cover (Kfz-Haftpflicht), and you can add partial (Teilkasko) or fully comprehensive cover (Vollkasko) just as for your main car. The difference lies in the starting classification: many insurers let a second car start in a better class than a car with no history at all.

Which SF class does a second car get?

There is no single rule. A second car does not automatically inherit the SF class of your first car. Two situations are common:

Standard classification: if the car has no claim-free years of its own, the insurer applies its normal rules for first-time policies – at worst, the same class as a beginner.
Special classification (second-car rule): under certain conditions, insurers place the second car in a better class. Allianz's published SF table, for example, lists the special class SF ½ for second cars. Other insurers have their own rules, some more generous, some stricter.

You will find the rates that typically go with each class in our guide to SF class and the no-claims discount.

What insurers usually require

Conditions vary by policy, but according to the ADAC they often include:

The first car is already insured and is not in SF class 0.
The first car's claim-free history meets the policy's requirements.
The policyholder, registered keeper and named drivers fit the rules – typically the second car is registered to the same person or to their spouse or partner.
The age and driving experience of the named drivers are taken into account.

Ask the insurer to confirm in writing which SF class you will actually get and which conditions apply.

A second car for your son or daughter

The second-car rule is especially popular with families: the young driver's car is registered to a parent and insured as the parent's second car. The new driver starts in a better class than they could get with a policy of their own. The German consumer advice centres (Verbraucherzentrale) mention this as a way for new drivers to save.

After a few claim-free years, the no-claims history can, under certain conditions, be transferred to the child. Bear in mind that the person giving up the discount usually loses it, and normally only as many years can be transferred as the recipient could have built up given how long they have held a licence. More on this in our guide to car insurance for young drivers.

Same insurer as your first car?

You do not have to insure all your cars with one company. Because the second-car rule is often tied to an existing policy with the same insurer, it makes sense to ask your current insurer first and then compare with others – some also offer good starting classes without an existing contract. Remember that the same SF class does not mean the same premium: type class, regional class, mileage and named drivers all play a part. See car insurance cost in Germany for the full picture.

Alternatives: interchangeable and seasonal plates

If the second car is not used all the time, two options may be worth a look:

Interchangeable plate (Wechselkennzeichen): two vehicles of the same vehicle class, such as two passenger cars, share one number plate. Only the car currently wearing the plate may be driven. According to the ADAC, both cars still have to be insured and taxed separately; insurer discounts are possible but not guaranteed.
Seasonal plate (Saisonkennzeichen): the car is registered only for a fixed period of two to eleven months each year – a convertible for the summer, for example. Outside that period it must not be used on public roads.

How to compare second-car quotes

Note the SF class of your first car from your latest premium invoice.
Decide who will be keeper and policyholder, and check that this fits the second-car rule.
List all regular drivers honestly, including young drivers.
Compare offers with identical details, paying attention to the SF class actually offered.

Frequently asked questions about second-car insurance

Does a second car get the same SF class as the first car?

Not automatically. Many insurers offer a special classification for second cars that is better than a beginner's class. Which class you get depends on the policy.

Does the second car have to be with the same insurer?

No. The second-car rule is often linked to an existing policy with the same company, but comparing other insurers is still worthwhile.

Can I register my child's car in my name?

This is a common way to get a better starting class. Your child must be declared truthfully as a driver. Later, the no-claims history can be transferred under certain conditions.

Is an interchangeable plate cheaper than a second car?

It depends. Both vehicles still have to be insured and taxed. Ask the insurer whether it offers a discount for interchangeable plates.

What happens to the second car's class after a claim?

If a liability or fully comprehensive claim is paid, the second car is downgraded according to the policy's downgrade table, like any other car.
