GermanyHow is fault determined in a traffic accident?
Fault is determined by assessing each driver’s conduct against the duty of care, apportioning liability based on contribution to the accident under StVG § 17 and BGB § 254 — with courts applying presumptions (e.g., rear-end = following driver at fault) unless rebutted.
What the Law Says
German traffic accident fault is not 'all or nothing' — it’s a proportional assessment based on conduct, causation, and shared responsibility. Two core statutes govern this: one for multi-vehicle liability, and one for victim-contributed fault.
StVG § 17 governs how liability is divided when multiple vehicles cause damage. It requires courts to weigh the circumstances — especially which party contributed more to causing the harm — to assign shares of liability between vehicle owners. This applies both toward injured third parties and among the owners themselves.
BGB § 254 addresses contributory negligence: if the injured person’s own fault (e.g., sudden braking without cause, ignoring traffic signals, or failing to mitigate damage) helped cause or worsen the injury, their compensation is reduced proportionally — again based on relative causal contribution.
Both statutes use the same standard: liability and compensation depend 'in particular on the extent to which the damage was predominantly caused by one or the other party.' There is no fixed formula — judges assess evidence, witness statements, skid marks, dashcam footage, and expert reports to reach a fair apportionment.
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.

What Courts Have Said
German courts apply practical presumptions to streamline fault analysis — especially in common crash types — but always allow drivers to rebut them with credible evidence.
In rear-end collisions, the following driver is presumed at fault due to failure to maintain safe distance or inattention. This presumption can only be overcome by clear evidence of an unforeseeable, unavoidable event — such as sudden, illegal stopping by the lead vehicle without warning.
What to Do
Gather evidence immediately: photos of positions, damage, road conditions, and traffic signs; note weather, lighting, and witness contact details.
Report the accident to police if injuries, major damage, or disputed fault are involved — required by law for insurance and liability purposes.
Exchange full contact and insurance details with all drivers — do not admit fault verbally or in writing at the scene.
Notify your insurer within one week (standard policy requirement), and submit a written accident report with supporting evidence.
Consult a lawyer before accepting any liability admission or settlement offer — especially if injuries or complex multi-vehicle involvement exist.
