Question 6206
The rear fog light must be used...
- in case of rain, snowfall, or clouds of dust or smoke.
- when weather or environmental conditions are especially unfavorable.
- whenever weather or environmental conditions reduce visibility.
Show answer and explanation
Correct answer: when weather or environmental conditions are especially unfavorable.
The rear fog light is required only when conditions are especially unfavorable, with thick fog, very heavy rain, heavy snowfall or dense clouds of smoke or dust. Rain, snow or dust that reduces visibility without reaching that level is not enough, and the light is then prohibited because it causes glare. In the image, the SUV ahead has it on in the fog.
