What Lights Should You Turn On in Foggy Weather?
2 Answers
In foggy weather, vehicles should turn on fog lights and hazard warning lights. The relevant details are as follows: Turning on fog lights: Fog lights have stronger penetration, so they must be turned on in foggy conditions. Most new car models now have hazard lights and turn signals that do not interfere with each other. Moreover, turn signals have higher priority, meaning that when hazard lights are on and a turn signal is activated, the hazard lights automatically turn off, and the corresponding turn signal lights up. After the turn signal is turned off, the hazard lights automatically resume. Turning on hazard lights when driving straight: Hazard lights can be turned on when driving straight or on highways to make it easier for vehicles behind to spot you. However, they should be turned off when making turns. When hazard lights are on and you activate a turn signal, the hazard lights automatically cancel and switch to the turn signal. Once the turn signal is turned off, the hazard lights automatically resume.
I've driven long distances many times, especially on foggy mountain roads. Whenever I encounter heavy fog, I immediately turn on both front and rear fog lights. Fog lights are specially designed with low and wide beams that can penetrate the fog to illuminate the road without reflecting back like high beams, which create a 'white wall' effect that actually reduces visibility. High beams are practically a trap in foggy conditions - I tried using them once and instantly lost visibility, quickly switching them off to stay safe. When driving in fog, I slow down and maintain at least twice the normal following distance, so I can stop safely if the car ahead brakes suddenly. The fog light switch is usually located near the steering wheel or on the dashboard, marked with a fog symbol - just press it to activate. Developing safe driving habits is crucial to prevent tragedies. Also, I strongly advise against speeding in thick fog - it's better to arrive late than to take unnecessary risks.
