GermanyHow is liability apportioned in a multi-vehicle accident?
In Germany, liability in multi-vehicle accidents is apportioned based on each vehicle owner’s share of causation — especially which vehicle contributed more to the damage — not automatically split equally.
What the Law Says
German law does not assume equal liability when multiple vehicles cause an accident. Instead, it requires a careful assessment of how much each vehicle — and its operator — contributed to the damage.
Under StVG § 17, if a single injury or property loss results from more than one motor vehicle, the vehicle owners’ internal liability toward each other depends on the circumstances — especially whether the damage was predominantly caused by one vehicle or the other.
This rule also applies when one of the involved vehicle owners themselves suffers damage — meaning they can seek partial reimbursement from the other owner(s) based on relative causation.
Liability is fully excluded only if the accident resulted from an unavoidable event — defined narrowly as one where both the vehicle owner and driver exercised all due care required by the circumstances, and no defect or failure in the vehicle played any role.
Statutory TextWird ein Schaden durch mehrere Kraftfahrzeuge verursacht und sind die beteiligten Fahrzeughalter einem Dritten kraft Gesetzes zum Ersatz des Schadens verpflichtet, so hängt im Verhältnis der Fahrzeughalter zueinander die Verpflichtung zum Ersatz sowie der Umfang des zu leistenden Ersatzes von den Umständen, insbesondere davon ab, inwieweit der Schaden vorwiegend von dem einen oder dem anderen Teil verursacht worden ist.
— StVG § 17 (1) — Road Traffic Act
Statutory TextDie Verpflichtung zum Ersatz nach den Absätzen 1 und 2 ist ausgeschlossen, wenn der Unfall durch ein unabwendbares Ereignis verursacht wird, das weder auf einem Fehler in der Beschaffenheit des Kraftfahrzeugs noch auf einem Versagen seiner Vorrichtungen beruht. Als unabwendbar gilt ein Ereignis nur dann, wenn sowohl der Halter als auch der Führer des Kraftfahrzeugs jede nach den Umständen des Falles gebotene Sorgfalt beobachtet hat.
— StVG § 17 (3) — Road Traffic Act
What Courts Have Said
German courts emphasize that apportionment isn’t about assigning blame like in criminal law — it’s about measuring each vehicle’s contribution to the harm, including both operational risk and driver conduct.
The court confirmed that liability in multi-vehicle crashes is determined by weighing each vehicle’s operational risk (Betriebsgefahr) and any individual driver fault — not by rigid formulas or equal division.
What to Do
Gather evidence immediately: photos, witness contacts, dashcam footage, and police report.
Do not admit fault or agree to equal liability — German law requires individualized apportionment.
Notify your insurer promptly and provide full details; request a formal liability assessment.
Consult a traffic law attorney if liability is disputed or injuries are serious.
