# Explanation: Driving in Fog
When there is poor visibility due to fog, it is essential to **increase the safety distance** with the vehicle in front of you. This gives you more reaction time in case of sudden braking that you might not see in time. Additionally, you should reduce your speed cautiously (not necessarily to the minimum) and keep your headlights on to improve visibility, but you should not keep your foot constantly on the brake, as this indicates poor driving technique.
