Fog is one of the most dangerous weather conditions in which to drive.You can basically driving in a cloud of water vapor and if you do not to drive- Don't.

          If you live in a cities located at highlands where there are regular foggy conditions, you need to have your vehicle equipped with fog lights. Installation of fog lights is regulated by law and you need to know the specs of the foglight at your local LTO district. Fog light should not be turned on  when there is no Fog because these  lights emits a  brighter light compared to regular headlights and turning them on at night with no fog may cause the driver of the oncoming vehicle to be blinded momentarily by the glare.

        Darkness makes the problem of fog even worse.The water droplets from the fog reflect the light from your headlights right back at you.Keep your headlights at low beam to reduce glare as much possible. Drive slowly and be ready to stop if you see any red or white lights in front of you. It is possible to see if someone in the wrong lane. Approach any light source with a great deal of caution.
