Radar speed signPoland
43. Radar speed sign
A radar speed sign warns drivers that vehicle speeds may be monitored by a fixed camera, mobile radar, lidar or average-speed enforcement system. It reminds drivers to check and respect the applicable speed limit.
The sign does not normally establish the speed limit itself. Drivers must follow the general, posted or variable speed limit applying to the road and must not brake suddenly merely because speed enforcement is indicated.

What should a driver understand from a radar or speed-camera warning in Poland?
Polish D-51 warns of an automatic speed check at a point. D-51a marks the start of an average-speed monitoring section and D-51b its end. Follow the applicable speed limit throughout the section; the monitoring notice alone does not establish a new numerical limit.

Should you brake abruptly when you notice a radar sign in Poland?
No. Adjust to the lawful and safe speed smoothly, leaving adequate space behind and ahead. Enforcement information does not authorise sudden unsafe manoeuvres or stopping to inspect the camera.
