In German traffic law, 'Eichung' refers to the official calibration process that ensures measuring devices are precise and trustworthy. This is especially relevant for devices like speed cameras, breathalyzers, and tachographs, whose data can lead to fines or legal proceedings. For driving theory exams, understanding calibration confirms the integrity of traffic monitoring and why its accuracy is paramount for fair enforcement.
Eichung
Calibration is the legally mandated process in Germany to ensure the accuracy and reliability of measuring instruments, particularly those used for traffic enforcement like speed cameras and alcohol testers.
Quickly understand the most important facts, rules, and meanings related to Calibration in German driving theory for Germany. This focused summary helps learners revise key terminology, traffic concepts, and exam-relevant knowledge efficiently.
See how Calibration appears in realistic driving situations relevant to Germany. These examples explain correct behaviour, safety implications, and how Calibration connects to German driving theory exam questions.
You receive a speeding ticket from a fixed speed camera on a German Autobahn, but you believe the measurement might be inaccurate.
Inquire whether the speed camera was officially calibrated ('geeicht') and its calibration certificate ('Eichbescheinigung') is valid for the date of the alleged offense.
For a speed measurement to be legally valid in Germany, the device must have undergone regular official calibration. If the calibration is expired or unproven, the measurement's validity can be challenged in court, potentially leading to the dismissal of the fine.
After a traffic stop, a police officer asks you to take an alcohol breath test using a handheld device.
Comply with the request, but be aware that the device used for official evidence must be a type-approved and officially calibrated 'Alkomat' (breathalyzer).
The legal weight of an alcohol test result relies heavily on the device's calibration. While a preliminary screening device might be used, any reading intended for legal proceedings must come from an officially calibrated device to ensure its accuracy and therefore its admissibility as evidence in German courts.
As a professional driver in Germany, your vehicle is stopped for a routine check, and the police inspect your digital tachograph data.
Ensure that the tachograph in your commercial vehicle has been regularly inspected and officially calibrated within the stipulated legal intervals.
Tachographs record crucial data like driving hours and speed. For this data to be legally compliant and accepted by authorities in Germany, the tachograph must be regularly calibrated by an authorized workshop according to strict regulations. An uncalibrated tachograph can lead to severe fines for the driver and the company.
Learn about 'Eichung', the official calibration process in Germany. This ensures accuracy for traffic enforcement devices like speed cameras and alcohol testers, a key concept for driving theory.
In Germany, 'Eichung' refers to the official, legally prescribed process of examining a measuring device to ensure it complies with metrological regulations, especially regarding error limits set by the Measurement and Calibration Act (Mess- und Eichgesetz). Unlike general 'Kalibrierung' (calibration) which simply determines values and uncertainties, 'Eichung' is a sovereign act resulting in a pass/fail decision (calibrated/not calibrated) for devices used in legally regulated areas.
Historically, calibration protected consumers from fraudulent measures. Today, it generally serves consumer protection and fair trade. Any measuring device where there is a public interest in its accuracy is subject to legal calibration requirements, including those in commerce, environmental protection, medicine, and crucially, traffic enforcement.
For German driving theory and practical application, official calibration is fundamental to the legal validity of measurements taken by enforcement devices. This ensures that any data used in legal proceedings for traffic violations is precise, reliable, and trustworthy, thereby upholding fairness in the application of traffic law. Without proper calibration, the accuracy of readings from devices like speed cameras or alcohol testers could be challenged, potentially invalidating evidence in court.
This legal requirement underlines the importance of maintaining high standards for measurement accuracy in all official capacities, particularly when those measurements can impact citizens' rights or lead to penalties. The 'Eichbescheinigung' (calibration certificate) serves as proof of this compliance.
Several types of devices frequently encountered in German traffic enforcement are subject to 'Eichung' to ensure their measurements are legally sound:
Geschwindigkeitsmessgeräte) must be regularly calibrated to accurately record vehicle speeds.Alkoholtestgeräte) must be calibrated to provide reliable readings for legal thresholds.Tachographen) that log driving times, rest periods, and speeds must be calibrated to ensure compliance with transport regulations.Abgasmessgeräte) to check engine management and exhaust systems also falls under calibration requirements.In Germany, the Physikalisch-Technische Bundesanstalt (PTB) is responsible for the type approval (Bauartzulassung) of calibratable measuring devices. Only devices that have passed this type approval are eligible for calibration. This initial process ensures the device's design and characteristics comply with relevant EU directives and accuracy classes.
Once a device is type-approved, regional calibration offices (Eichämter) in the federal states perform the actual calibrations. Since 2015, the initial calibration for many devices has been replaced by a manufacturer's declaration of conformity according to EU directives. Subsequent calibrations are then regulated nationally. The operator of the measuring device is responsible for timely requesting re-calibration from the competent authority.
The validity period for calibration varies by device type (e.g., electricity meters might have a 16-year initial period). Renewal of calibration validity (Eichgültigkeitsdauer) can often occur through official random sample testing of a series of devices, extending the validity if accuracy is maintained.

'Eichung' (official calibration) is a legally mandated process in Germany for specific measuring devices used in regulated areas, like traffic enforcement. It results in a pass/fail decision. 'Kalibrierung' (general calibration), by contrast, is a scientific or industrial process to determine measurement values and uncertainties without legal certification.
Official calibration ('Eichung') is crucial because it ensures these devices provide accurate and legally trustworthy measurements. For traffic enforcement in Germany, data from officially calibrated devices is essential for legal validity in court and for issuing fines, upholding principles of fairness and legal certainty.
Measurements from officially calibrated devices in Germany are usually accompanied by an 'Eichbescheinigung' (calibration certificate). While you typically won't see this roadside, if you receive a traffic fine, you have the right to request proof of the device's valid calibration for the date of the offense during any legal challenge.
Devices whose measurements are intended for use as legal evidence in Germany, such as those determining speed for fines or alcohol levels for DUI charges, must be officially calibrated ('geeicht'). Simpler screening devices for initial checks might not require the same legal calibration if their results are not directly used for formal legal proceedings.
If a speed camera or similar traffic enforcement device in Germany is found to be uncalibrated or its calibration is expired, any measurements taken by it during that period may be legally invalid. This can lead to the dismissal of fines or charges based on those specific measurements, highlighting the importance of 'Eichung' for fair traffic law enforcement.
