Q8037 the lights

[ben em]

there is thick fog and you park your car on the road, what is wrong?
A. The rear fog light must be lit
B.the parking lights and the red rear lights must be lit
c. The front fog light must be lit.

Why the correct answer is A.

In the book it says, the front fog lights are never obligated to be switched on. And while parking and waiting, the dipped headlights, front and rear fog lights are allowed to be switched on when fog, snow or heavy rain, so both A and C are not correct?

[GRO]

Correct.
Answer B is correct.
