What is the recommended action for driving in fog?

Turn on all lights on low beams
Use high beams for better visibility
Flash lights from low to high
Speed up to get through quickly

The correct answer is: Turn on all lights on low beams

Turning on your low beam lights is the recommended action when driving in fog. Low beams are designed to provide adequate illumination without reflecting off the fog, rain, or snow, which can create glare and make visibility worse. High beams, on the other hand, can cause the light to bounce back and create a blinding effect, reducing your ability to see clearly. This is why using low beams is a safer choice in foggy conditions. The other options do not prioritize safety and can contribute to poor visibility or hazardous driving conditions. Flashing lights can confuse other drivers and are not beneficial for increasing your visibility. Speeding up in fog is dangerous, as reduced visibility requires more cautious and slower driving to ensure you can react to obstacles or other vehicles safely.
