46. 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 Czechia?

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 Czechia?

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 Czechia?

Not necessarily. A board showing your measured speed provides feedback; its presence does not establish whether an enforcement system is also operating. Follow the applicable legal speed limit and do not assume that the absence of an obvious camera means there is no enforcement.
