How should you adjust your speed in heavy fog?

In heavy fog, visibility can be significantly reduced, often to just a few feet. This makes it challenging to see other vehicles, road signs, and potential hazards. Reducing speed is crucial because it allows for better reaction times and increases safety for both you and other road users. When driving at a lower speed, you have more time to react to sudden changes in your environment.

Increasing your following distance is equally important in foggy conditions. With reduced visibility, you may not be able to see vehicles in front of you until you are very close. By increasing the space between you and the vehicle ahead, you create a buffer that provides additional time to respond if the vehicle suddenly stops or slows down.

Maintaining the same speed would not account for the decreased visibility and reaction time needed in fog. Driving faster to reach your destination more quickly can lead to dangerous situations and reduced control over your vehicle. Additionally, using high beams in fog can create a glare that reflects off the moisture in the air, further diminishing visibility. Therefore, adjusting your speed and increasing your following distance is the best practice for driving safely in heavy fog conditions.
