Question 7492
In weather conditions that significantly reduce visibility...
- the vehicle's lighting system must be used.
- only the fog lights may be used.
- the lights must not be used unless a sign requires them to be turned on.
Show answer and explanation
Correct answer: the vehicle's lighting system must be used.
If fog, heavy rain, snow, smoke or dust greatly reduces visibility, lights are required, even during the day and without any sign requiring them. Fog lights are not the only lights you may use. You must use your position lights and, at the front, front fog lights, low beams or high beams. In the image, both cars are driving with their lights on in daytime fog.
