If driving in rainy conditions that significantly reduce visibility, which lighting are you obliged to use?

Question

DentroTest · Accepted Answer

The correct answer is to use the low beam headlights (dipped headlights). Detailed Analysis: Low Beams: These are mandatory when weather or environmental conditions reduce visibility. They allow you to see the road without dazzling others and, crucially, they activate the rear position lights so you can be seen by vehicles following you. High Beams: These are not recommended in rain or fog. The powerful light reflects off the suspended water droplets, causing a 'mirror effect' or self-glare that further reduces the driver's visibility and blinds other road users. Daytime Running Lights (DRL): These are insufficient. While they make the vehicle visible from the front, most systems do not activate the rear lighting, leaving the car 'invisible' from behind in bad weather conditions.
