The RSI function's camera sensor has limitations just like the human eye. Find out more about this in the section on the camera sensor limitations.
Signs which indirectly provide information on a prevailing speed limit, e.g. name signs for towns/districts, are not recorded by the RSI function.
Here are some other examples of what can disrupt the function:
- Faded signs
- Signs positioned on bends
- Rotated or damaged signs
- Concealed or poorly positioned signs
- Signs completely or partly covered with frost, snow and/or dirt.
