48. 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 Germany?
A notice about speed monitoring warns that your speed may be checked. It does not itself replace the applicable speed limit. Follow the statutory and posted limits whether or not a check has been announced.

Which speed limit applies when a radar warning is displayed in Germany?
Follow the speed-limit sign, applicable speed zone or statutory road and vehicle limit. A camera symbol or enforcement notice must not be mistaken for a sign raising or ending that limit.

Should you brake abruptly when you notice a radar sign in Germany?
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.
