What happens after an accident with a driver not named on the car insurance in Germany?
In short
The motor liability insurance (Kfz-Haftpflicht) still pays the other party, because in Germany every authorised driver is covered. What happens next: the group of drivers is a pricing factor, so after the accident your premium is recalculated back to the start of the current insurance year. If you deliberately left the driver off, a contractual penalty (Vertragsstrafe) is often added.
What a recalculation can look like. The rules come from the model terms, the amounts are worked examples.
Example
Typical range
Policy for you only, EUR 480 a year, later a driver under 25
about EUR 650 to 850 a year after recalculation
Policy for a couple, later an open group of drivers
about 10 to 30 percent more
Couple over 25, later an 18 year old driver
about 50 to 100 percent more premium
Amounts are rules of thumb from practice, as of October 2026.
The model terms leave the amount of the penalty open, your contract decides.
Worked example
Son, 19, drives his mother's car
Policy for drivers aged 25 and over, premium EUR 480. In July the son causes a parking damage of EUR 2,500.
Other party's damage
EUR 2,500, paid by the liability insurance
Recalculation from January with a driver under 25
about EUR 760 instead of EUR 480
Back payment for the current year
about EUR 280
No-claims downgrade
as with any liability claim
The other party is covered. The mother pays about EUR 280 extra and the higher premium in future, plus a penalty if she acted deliberately.
Liability: the injured party is always protected
Motor liability insurance is compulsory in Germany. Under the model terms, besides the keeper and owner, the driver of the vehicle is covered too. Anyone who drives your car with your permission is an authorised driver (berechtigter Fahrer), even if they are not named in the policy.
So the other party is compensated. Whether a driver was named is something the insurer settles only with you as the policyholder.
The group of drivers is a pricing factor
In the model terms, the group of users (Nutzerkreis) and their age are factors used to calculate the premium. A driver who was not declared is therefore not a reason to refuse cover, but a reason to correct the premium.
If you gave incorrect information or did not report a change, the premium that matches the real group of drivers applies retroactively from the start of the current insurance year. If you acted deliberately, a contractual penalty is added. Each insurer sets the amount in its own terms.
Situation
What usually happens
A friend drives once with permission, policy covers only you
Young driver uses the car regularly, never reported
recalculation with surcharge, penalty if deliberate
Driver without a valid licence
breach of duty, the insurer may seek recourse from you
Someone takes the car without permission
not an authorised driver, recourse against that driver possible
Comprehensive cover depends on your terms
In partial and fully comprehensive cover (Teilkasko and Vollkasko), the group of drivers is also a pricing factor. The model terms provide for a backdated recalculation here too, not for refusing payment.
Your tariff may deviate from the model. Read the clause on the group of drivers in your contract before letting someone drive who is not named there.
What to do after the accident
Report the accident truthfully with the person who was actually driving. Naming someone else to avoid the surcharge risks far more than the extra premium.
If that person keeps driving the car, update the group of drivers straight away. An open group of drivers costs more, but is often cheaper than a recalculation plus a penalty.
Step by step
Report the accident with the actual driver.
Read the clauses on the group of drivers and on penalties in your contract.
Update the group of drivers at once if the person keeps driving.
Check that the insurer's recalculation starts on the right date.
Compare offers to see whether another tariff with this group of drivers is cheaper.

Youngest driver's age stated
Penalty clause known
Changes to the group of drivers reported without delay

Thinking there is no cover at all and not reporting the accident
