Can you drive a car if the wiper on the driver's side does not work in the rain?
Explanation
A working wiper on the driver's side is essential for clear visibility in rain. The rules forbid driving with this fault, because it poses a direct danger to road safety.
KET reference: KET 234.4: Driving a motor vehicle is forbidden if, in rain, snow or fog, the wiper on the driver's side does not work.
