In the image, the driver is moving through extremely dense fog with almost zero visibility, yet their headlights are not turned on. Without lights, other vehicles can barely see the car, increasing the risk of rear-end collisions or sideswipes. The driver also appears to be following traffic too closely for such limited visibility. This combination of poor lighting, reduced distance, and heavy fog creates a high-risk situation where even a small mistake could cause a serious crash.

Drivers should always slow down, increase following distance, and turn on low-beam headlights (never high beams) when driving in fog. Using lights makes the vehicle visible to others and helps illuminate the road without reflecting glare back at the driver. Workers should avoid sudden lane changes, stay centered in their lane, and use fog lights if equipped. Practicing these controls reduces the risk of collision and keeps everyone safer during low-visibility conditions.
