When driving in fog, what should you turn on?

High beams
Low beams
Fog lamps
Hazard lights

The correct answer is: Fog lamps

When driving in fog, it is important to have appropriate lighting to increase visibility for yourself and other drivers. Choosing to turn on high beams (A) is incorrect because the light will reflect off of the fog and reduce visibility even further. Low beams (B) may not provide enough visibility and could also reflect off of the fog. Hazard lights (D) are not a suitable option because they are generally used when the vehicle is stopped or in an emergency situation. Fog lamps (C) are specifically designed for driving in foggy conditions and provide a lower, wider light beam that does not reflect off the fog. This helps to improve visibility while also reducing glare for other drivers. Therefore, turning on fog lamps is the best choice for driving in fog.
