How to Follow Vehicles in Foggy Weather?

[KateLynn]

Precautions for following vehicles in foggy weather: 1. Turn on fog lights and low beams, but avoid using high beams; 2. Frequently use the horn to warn pedestrians and vehicles, and respond immediately to other vehicles' horns to indicate your position; 3. Drive at low speed, maintaining a sufficient safe distance from the vehicle ahead to avoid emergency braking; 4. In heavy fog, try to use the remaining visibility to follow the lane markings, but be careful not to cross the lines, as this can make oncoming traffic dangerous; 5. In dense fog, condensation on the windshield can further impair visibility, so consider using the wipers to clear the condensation.

Having driven for 20 years, I've encountered many foggy days, and the most crucial thing is to drive slowly at low speeds. Turning on fog lights and low beams is definitely necessary, but never use high beams, as they will create a blinding white haze in front of you. When following another car, pay special attention to the taillights of the vehicle ahead. It's safest to follow a large truck by tracking its red outline. Maintain at least a 3-second distance from the car in front, and if visibility drops below 100 meters, keep your speed under 40 km/h. Remember to lightly tap the brakes occasionally to alert drivers behind you. If the windshield wipers aren’t clearing the view properly, turning on some cold air directed at the windshield can prevent fogging.

As a safety officer, I often remind my colleagues that the key to driving in fog is making sure other vehicles can see you. Turning on your front and rear fog lights is a basic step, and when visibility drops below 50 meters, immediately activate your hazard warning lights. It's best to double your usual following distance. If you see the brake lights of the car ahead suddenly all light up, follow with gentle braking immediately. Pay special attention to patchy fog on highways—these localized areas of dense fog require slowing down in advance. If visibility is truly poor, turn on your hazard lights, pull over, and wait for the fog to clear before continuing—it's much safer.

Last time driving on the highway in fog scared me to death! Now I've learned my lesson: I turn on navigation to check real-time visibility alerts, and follow cars by keeping a close eye on the position of their brake lights. When the fog gets thick, I secretly follow logistics trucks—they're experienced and maintain steady speeds. Keep the rear window defroster on at all times, and remember to turn on the mirror heaters too. Once I noticed a car following too closely behind me, so I turned on the hazard lights as a warning, and it eventually backed off. I recommend keeping a high-power flashlight in the glove box—just in case you break down in the middle of the night.

Driving in fog has unique physical characteristics: Water mist can increase braking distance by over 15%. It's recommended to activate the front and rear windshield defogging functions, and don't forget the rearview mirror heating. When following another vehicle, don't focus on its rear end—watch the position of its rear wheels to judge movement. During early morning when fog is thickest, sticking your hand out the window to feel humidity changes with the back of your hand can be quite interesting. Be extra cautious on bridges and valley sections, as these areas are particularly prone to fog accumulation. Tire pressure monitoring is also crucial, as insufficient tire pressure is especially dangerous on slippery roads.

I once encountered heavy fog with visibility less than ten meters on a long-distance drive. My experience is: maintain stable engine RPM and avoid sudden acceleration to prevent misjudgment by following vehicles. Following behind buses or tanker trucks is the safest option, as professional drivers operate more cautiously in foggy conditions. Check the dashboard every five minutes to ensure all lights are functioning properly. Once, I spotted a car parked on the emergency lane in the fog and started changing lanes 300 meters in advance to avoid it. Remember to carry anti-fog spray – when temperature differences cause windshield fogging, a quick spray instantly clears it up.
