Lightning alarm in Calau: Speed checks on Viersener Straße today!
In Calau today the motto is to be careful and take your foot off the gas! On July 18th, 2025 there will be a lot of flashing on Viersener Straße in a 10 km/h zone. The public received news of the speed controls as early as 6:33 p.m., which were clarified based on current information at 8:05 p.m. Here, any speed offender can be stopped quickly and mercilessly, because “flashing” is not a joke here, but the reality for all drivers who do not follow the traffic rules.
The Calau city administration has increased its security measures. These speedy checks are not only a sensitive reminder, but also a sign that the authorities want to make the streets safer. The basis for the measures is the road traffic regulations (StVO) and the catalog of fines, which determine what happens if you exceed the speed limit or commit other administrative offenses. “If you drive too fast, you can expect fines and even a license suspension,” warns the city administration. Anyone who values their points in Flensburg should think carefully about whether they want to exceed the permitted speed.
Surveillance by the authorities
But who exactly carries out these checks? In Germany, it is mainly the police and public order offices that monitor road safety through the daily presence of vehicles, be they cars, trucks or even bicycles. “The nationwide catalog of offenses regulates the fines and the points in Flensburg that you can face,” explains bussgeldkatalog.org. It becomes clear that the controls are not carried out without reason: they are intended to have a deterrent effect on road users so that fewer accidents due to speeding occur in the future.
Mobility on German roads is linked to high sales every day. Also the speed camera map bussgeldkatalog.org shows the current locations of speed cameras and enables drivers to find out about speed traps. There are over 52,000 permanently installed radar devices in Germany that are constantly updated. Particularly practical: Users can filter speed cameras by entering their zip code. And while the trend for mobile speed cameras is increasing, fixed devices don't seem to be completely out of fashion.
The technology behind it
But how does flash actually work? There are various measurement techniques that can be used by the police. These include radar systems, light barrier measuring devices and laser knives. Induction loops and piezo technology are also used to control driving behavior and hold speeders accountable. Taking your foot off the accelerator is not just an expression, but a necessary measure to ensure road safety. Anyone who thinks they can escape control should think about the speed zone in which they are moving.
Another interesting point is the tolerance in speed controls. For speeds below 100 km/h a tolerance of 3 km/h applies, while for faster journeys 3% can be deducted from the measured speed. But be careful, the rules have become stricter: "Radar detectors are prohibited in cars, as are real-time warning apps on smartphones. According to paragraph 23, paragraph 1b of the StVO, these may not be used," reminds us bussgeldkatalog.net.
Whether there are flashing lights or not, it is clear that anyone who drives carelessly can quickly get into trouble. So all we can say is: pay attention to your speed and enjoy the ride without worrying about speed traps!
