When should fog lights come on?
In fog or other low visibility conditions, you should turn on your main headlights. Fog lights should be activated in addition to your dipped headlights when visibility falls to less than 100m.
Is it illegal to drive with front fog lights on?
Rule 226 of the Highway Code states: “You MUST NOT use front or rear fog lights unless visibility is seriously reduced as they dazzle other road users and can obscure your brake lights. “You MUST switch them off when visibility improves.”
How do you turn on the fog lights on a car?
Fog lights have a dedicated switch that allows them to be turned on separately from the headlights and the tail lights. The switch can be a button or a collar on the headlight stalk and typically has a semi-circle symbol with three wavy lines. Simply twist the collar or push the button to turn your fog lights on.
When should you turn off your fog lights?
When you’ve gone through the rain and the mist and no longer need to make use of your fog lamps for now, it’s time to turn them off. You’ll want to do this because they tend to take up a lot of energy from your car battery. Start by twisting the inner ring back, and – when necessary – turning the headlights and tail lights off.
What kind of fog lamps do cars have?
Some cars, such as many Peugeot models, have a centre-mounted fog lamp. Many older cars have one single fog lamp in the right-hand rear light with a reversing lamp in the corresponding place in the left-hand light.
What happens when you drive through fog with headlights on?
In addition to acting like a cloud and blocking your view, the tiny water droplets or ice crystals decrease visibility even further by reflecting light that hits them. This makes driving through fog with headlights, and especially high beams, a frustrating and dangerous experience.
