Attention speed cameras in Arnsberg: There will be a check in Holzen today!
A look at the streets in the Hochsauerland district shows: Checks will be carried out everywhere today, November 12, 2025. A mobile speed camera is currently active in Arnsberg, asking drivers to slow down. Loud News.de The speed camera is located in Holzen, zip code 59757, where there is a speed limit of 50 km/h. The report about the speed camera being set up came at 6:44 a.m. this morning, with the last update following at 7:16 a.m. But be careful: the situation of traffic monitoring can change constantly and the speed camera locations specified are not guaranteed.
The aim of speed control in Germany is to increase road safety and educate drivers to drive in accordance with the rules. In 2013, over 5,000 drivers were warned for speeding and had to accept fines or even driving bans. Such controls also show how important it is to regularly check compliance with traffic rules, explains bussgeldkatalog.org.
Measuring methods and tolerances
How exactly the measurements are carried out is peppered with different methods. The mobile control in Holzen is expected to use radar measurements, one of the most common methods for determining speed. This technique works using the Doppler effect, in which electromagnetic waves are emitted and reflected. However, it also happens that measurement errors can occur, for example due to incorrect placement of the speed cameras. So it's not always easy to rely on the speed camera to accurately determine the actual speed in every case.
The tolerances for speed measurements are particularly noteworthy. At speeds below 100 km/h, 3 km/h is usually deducted from the measured value; at speeds over 100 km/h this deduction is normally three percent of the reading. This regulation ensures a certain fairness in the fine system, which often leads to objections against fine notices, especially if images are of poor quality or measurement errors are suspected, he said ADAC.
A call to reason
Given these circumstances, it is advisable for all road users to always keep an eye on speed limits. It is every driver's responsibility to follow the rules to protect not only themselves but also other road users. Because ultimately it's about our safety on the road. Mobile control today in Arnsberg is just one of many ways in which the authorities ensure that all drivers drive safely and in accordance with the rules.
So be vigilant and stick to the speed limits - not only will you do good business with the police, but you will also ensure better coexistence on the road!
