38. Speed feedback

Speed feedback is a traffic-safety system that measures an approaching vehicle's speed and displays it back to the driver. The display may show the measured speed together with a message, colour or symbol indicating whether the vehicle is travelling within the applicable speed limit.

Speed feedback displays are intended primarily to make drivers aware of their speed and encourage them to slow down when necessary. They normally serve a preventive or educational purpose rather than establishing a new speed limit.

What does a speed-feedback display show drivers in Austria?

A roadside display may detect an approaching vehicle and show its measured speed in km/h, sometimes with a smiley, flashing message or warning colour. It is a driver-awareness device; its exact design and deployment depend on the road authority.

Does the number on a speed-feedback board set the legal speed limit in Austria?

Normally no. A reading showing your measured speed is not itself a new regulatory limit. The limit comes from applicable laws and legally prescribed fixed or variable speed-limit signs; a separate enforceable speed sign must still be obeyed.

Is every speed-feedback board an enforcement camera in Austria?

No. Many feedback signs are installed for education and speed awareness. Speed enforcement may occur separately or nearby, so do not assume there is no enforcement; observe the legal limit regardless of whether you see a camera.
