Mobile speed cameras in Othal: Watch out for 70 km/h on June 25th!
Today, June 25, 2025, there is a mobile speed camera in Sangerhausen that could possibly alert you to the speed limits. According to news.de this is on Riestedter Straße in Othal, in a zone where a maximum of 70 km/h is permitted are. The report about the speed camera came in at 10:02 a.m., while the current information was updated at 1:05 p.m.
Speeding is still a big issue in Germany and is considered the main cause of traffic accidents. It is not for nothing that the Road Traffic Act (StVO) has set out clear regulations on fines for such violations. Mobile speed cameras are particularly important in this context because they can be set up quickly, often on tripods or in parked vehicles. The technology behind it is similar to that of stationary speed cameras and uses electromagnetic waves or light signals to precisely measure speed.
The technology behind the speed cameras
How does a speed trap actually work? According to bussgeldkatalog.org, speed measurement is based on the Doppler effect: radar waves are emitted and reflected back by the vehicle. This allows the speed of a vehicle to be determined quickly and reliably. In the event of violations, not only is the speed documented, but a photo of the vehicle and the driver is also taken, which further contributes to traceability.
In Germany there are now around 4,400 permanently installed radar measuring devices that are stationary or mobile. These speedlights are more than just a bogeyman for speeding drivers; They are also part of traffic education and are intended to increase traffic safety. They are becoming more and more versatile, especially since the introduction of new techniques such as section control, which measures the average speed over a longer section.
Responsibility and liability
One of the most important issues in speed checks is responsibility: in Germany the driver is liable for his violations, while in Austria owner liability applies. The tolerance values also vary depending on the country; In Germany, for example, there is a deduction of 3 km/h for speeds up to 100 km/h. The income from fines also ensures that the infrastructure and traffic monitoring in the municipalities are supported.
There are legal ways in Germany to inform citizens about speed checks, for example through radio stations that can warn about where the speed cameras are set up. In Austria, however, flashing from behind is common in order to comply with anonymity orders against vehicle owners. Even if some drivers find speed monitoring annoying, its goal is to increase road safety and reduce accidents, as can be read on Wikipedia.
