Coding Meaning Description
10 Dry There is no liquid water on the road or the water film height is below the dry-
moist threshold.
15 Moist There is liquid water on the road and the water film height is between the dry-
moist and moist-wet thresholds.
20 Wet There is liquid water on the road; the water film height has raised above the
moist-wet threshold.
25 Moist with salt Describes a moist road condition where the freezing temperature is lower than -
0.1°C.
30 Wet with salt Describes a wet road condition where the freezing temperature is lower than -
0.1°C.
35 Ice There is frozen water on the road, mostly in the form of ice or snow.
40 Snow There is snow on the road
45 Frost There is frost on the road
The factory settings for the moist and wet thresholds are 10 and 200 µm, respectively. These settings can
be adjusted in the sensor configuration (see screenshot).
