In Germany, 'Nachfahren' refers to a specific method of speed enforcement where police vehicles follow a suspected speeding vehicle. This technique, often used when static cameras are unavailable, involves measuring speed over a defined distance using calibrated police car odometers or specialized ProViDa systems. For learner drivers, knowing about 'Nachfahren' is important for recognizing various speed control methods and maintaining legal speeds on German roads, including the Autobahn.
Nachfahren (Geschwindigkeitskontrolle)
Following (speed control), or 'Nachfahren', is a method used by German police where they follow a vehicle for a measured distance to determine its speed.
Quickly understand the most important facts, rules, and meanings related to Following (speed control) in German driving theory for Germany. This focused summary helps learners revise key terminology, traffic concepts, and exam-relevant knowledge efficiently.
See how Following (speed control) appears in realistic driving situations relevant to Germany. These examples explain correct behaviour, safety implications, and how Following (speed control) connects to German driving theory exam questions.
You are driving on the German Autobahn, and there are no visible static speed cameras. You briefly exceed the recommended speed, thinking there's no immediate risk of being caught.
Maintain the legal speed limit at all times, even without visible enforcement signs or cameras, and be aware that unmarked police vehicles might be present and using 'Nachfahren' techniques.
German police actively use unmarked cars with 'Nachfahren' systems to monitor speed. Relying on the absence of visible cameras is a risky assumption and can lead to fines and points, as well as being unsafe.
A plain-clothed police car begins to follow your vehicle at a consistent distance for several kilometers on a rural road.
Ensure you are strictly adhering to all posted speed limits and traffic regulations. Do not attempt to evade or accelerate, as this could lead to more serious offenses or dangerous situations.
This is a typical scenario for 'Nachfahren'. The police are likely monitoring your speed and driving behavior. Maintaining legal speed and calm driving is the only correct response to avoid a violation.
You are preparing for your German driving theory test and encounter questions about different speed enforcement methods.
Familiarize yourself with various speed control methods mentioned in German traffic law, including 'Nachfahren', static radar, laser guns, and section control, to fully understand the scope of enforcement.
The theory test assesses your comprehensive understanding of road rules and enforcement. Knowing that 'Nachfahren' is a legitimate and common method helps you answer questions correctly and build a complete picture of German traffic regulations.
Learn about 'Nachfahren', a German police speed enforcement method where officers follow a vehicle to measure its speed. Essential for understanding various speed control techniques in your driving theory exam.
'Nachfahren' directly translates to 'following' or 'driving after' and, in the context of 'Geschwindigkeitskontrolle' (speed control), it describes a method of speed enforcement used by the German police. Instead of relying on stationary radar or laser devices, officers in a police vehicle will follow a target vehicle for a specific distance to accurately determine its speed. This method is particularly prevalent on motorways (Autobahnen) and other high-speed roads where traditional static measurements might be less effective or practical.
Police vehicles equipped for 'Nachfahren' will maintain a consistent distance behind the suspected vehicle over a measured stretch of road. The speed is then recorded using the police vehicle's calibrated speedometer or, more commonly, specialized video recording systems like 'ProViDa' (Proof-Video-Data-System). These systems record both the police vehicle's speed and the distance covered, providing highly accurate and verifiable evidence of a speed violation. This allows for a direct observation of the driver's behaviour and ensures that the measurement is fair and legally sound. The footage often also captures other potential traffic violations.
While not every specific measurement technique is detailed extensively in the theory exam, understanding the concept of 'Nachfahren' is part of a broader awareness of speed enforcement in Germany. The exam tests your general knowledge of traffic rules, speed limits, and the consequences of speeding. Knowing that police can use unmarked cars to monitor speed encourages drivers to maintain legal speeds at all times, not just when passing visible speed cameras. It reinforces the principle that speed limits are consistently enforced across the road network.
In Germany, specific tolerances are applied to speed measurements to account for potential technical inaccuracies. For the 'Nachfahren' method, these tolerances are typically higher than for static measurements due to the nature of the moving measurement. According to German regulations:
Awareness of the 'Nachfahren' method promotes safer driving by encouraging consistent adherence to speed limits. Drivers who are conscious that their speed can be monitored by moving police vehicles are less likely to speed up between fixed cameras. This contributes to a more uniform traffic flow and reduces the risk of accidents caused by sudden braking or aggressive driving in response to visible enforcement. It underscores the importance of maintaining a safe and legal speed at all times, rather than just anticipating known control points.

'Nachfahren' is a specific method of speed control used by German police where an officer in a police vehicle follows a target vehicle for a certain distance to accurately measure its speed, often using calibrated equipment or video systems like ProViDa.
Police typically use either their own calibrated speedometer in a marked or unmarked patrol car or advanced 'Police-Pilot' systems (such as ProViDa) that record video and speed data as they follow the vehicle. The distance and time are precisely measured to calculate the average speed.
Yes, German law applies specific tolerances to 'Nachfahren' measurements. If the police vehicle's speedometer is calibrated, a 15% deduction is applied; if uncalibrated, a 20% deduction is applied from the measured speed to account for potential variations.
Understanding 'Nachfahren' is important for your German driving theory exam because it highlights the various methods of speed enforcement. It encourages consistent adherence to speed limits on all roads, not just where static cameras are visible, reinforcing general road safety understanding.
Yes, unmarked police cars are commonly used for the 'Nachfahren' method in Germany, particularly on motorways and other major roads. This makes it crucial for drivers to maintain legal speeds at all times, as enforcement may not always be visually obvious.
