When driving in foggy conditions, you must:

Increase your speed
Use your high beams
Pay close attention to traffic
Drive with your hazard lights on

The correct answer is: Pay close attention to traffic

Driving in foggy conditions requires extra caution and attention to the road. Increasing speed will only make it harder to react to sudden changes or vehicles in front of you. Using high beams will also worsen visibility by causing glare on the fog. Driving with hazard lights on may lead other drivers to believe there is an emergency, causing confusion and potential accidents. Paying close attention to traffic is the best way to ensure your safety and the safety of others while driving in fog.
