When it rains, do you use your lights?

[IMm29]

As an addition if you use your hazard lights then you can't use your signal lamps (when changing lanes or turning at an intersection).

+1. Also, doesn't red travel farther and cut through better than yellow? like what mbeige said, rear fogs might be less confusing and may appear clearer than hazard lights.

As for the zero visibility, I can disagree with that. The worst rain that I’ve encountered caused the visibility to drop to only 5-10 meters but still I was able to see the red tail lamps of the vehicle ahead of me. The same goes for heavy fogs in Tagaytay.

Worst fog I've driven through was in Tagaytay a few years back. Driving in twisties through fog is different, and more difficult, than on straight highways. But, yes, the red tail lamps shone through the fog.

To add also, many people complain about the relatively low visibility of the road ahead BUT have dark & heavy tints in their windshield and front side windows.

Hehehe! Now this is another story.

Though if you have really poor eyesight then I think that you should instead pull over in a shoulder / gasoline station / parking lot / etc., use your hazard lights and just wait for the heavy rain to subside.
