ing intervention is not sufficient to keep the vehi-
cle in the lane.

in the following instances:
There is poor visibility, e.g. due to snow, rain,
R
fog, heavy spray, greatly varying light condi-
tions or strong shadows on the carriageway.
There is glare, e.g. from oncoming traffic,
R
direct sunlight or reflections.
Insufficient road illumination.
R
The windscreen is dirty, misted up, damaged
R
or covered in the vicinity of the camera, e.g.
by a sticker.
No, or several, unclear lane markings are pres-
R
ent for one lane, or the markings change
quickly, forexample, in a construction area or
junctions.
The lane markings are worn away, dark or cov-
R
ered up, e.g. by dirt or snow.
If the distance to the vehicle in front is too
R
short and thus the lane markings cannot be
detected.
The road is narrow and winding.
