26. 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 Finland?

It is an indication that speed may be checked or monitored at a point or along a section. Speed monitoring may use different equipment and signs, and any legal obligation to warn drivers depends on the authority and applicable law. It is not, by itself, a new numerical speed limit.

Which speed limit applies when a radar warning is displayed in Finland?

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 Finland?

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.
