With the arrival of winter weather…and the wind, fog, and snow that come with it, some traffic laws take on increased significance. The law regarding fog lights seems to cause confusion. Bend Police Lieutenant Chris Carney says it is illegal to have fog lights over 300 candlepower turn on at any time you are required to have your headlights dimmed. And…you can’t have those fog lights turned on unless there’s a condition that requries them, such as snow, fog, or heavy rain. If you approach an oncoming vehicle, you must turn them off.
