Camera-based sign detection
Where supported, goGPS Drive offers speed-limit sign detection. Results depend on camera view, lighting, sign readability and the installed version.
Different from a speed threshold
Sign detection evaluates the camera image. Speed-threshold recording uses a number you choose to log GPS events. The fixed traffic enforcement layer is a third, separate feature.
What to follow on the road
Detection can miss or misread signs. Follow actual road signs and traffic rules; an app result is not definitive confirmation of a legal speed limit.
