Can you switch on the high-beam headlights when there is fog at night?
A)Yes, in place of the fog light.
B)No, it is prohibited.
C)Yes, although it is not advisable because it may cause glare.Correct
Drivers' general reasoning is that high-beam or main beam headlights illuminate very well and dipped or low-beam headlights only a short distance. If we switch on the high beam in the presence of fog, this light will only illuminate the fog and our vision will not improve, and may even dazzle us. That is why it is advisable to use the low beam or the corresponding fog light.
