Use your low beams or fog lights. Fog or snow will reflect high beam light back in your eyes making it more difficult to see.

You should use low beams when driving in fog. It is more difficult to see driving with high beams in fog.
Snow+Fog Snow+Storm
Always use low beams because the high beam's rays reflect off the fog, the rain, or the snow particles at about the same level as your eyes, making each particle act like a tiny mirror. It reflects the light right back into your eyes and reduces your vision.
Some people seem to think so, but I absolutely don't. Driving really slowly is the only thing that helps in really heavy snow. I've been blinded many a time by people that use fog lights in addition to regular lights, and here in Norway it is forbidden to do so.
