People are only just realising what vital car button actually does
A lot of Brits like to think they're amazing drivers.
Most people want to believe they're cool, collected and super observant when behind the wheel. But, even if you're a master on the road, there still may be a few things you aren't too sure of.
For example, do you know what every single thing inside your car does? It turns out, not everyone does, as a common button is confusing a lot of drivers online.
Someone got the conversation started on Reddit, when they asked: "What does this button do?" They shared it alongside a picture of the button, which appeared to show a symbol of a light glowing.

Since the question was asked lots of people have replied with their suggestions. From the sensible to the absolutely wild - people offered all sorts of ideas as to what the symbol meant.
One person said: "Fog light. Not for use mist light mist, haze, drizzle, sleet, overcast, wet or perfectly sunny days. Use it in fog. Somehow this is confusing for a lot of drivers."
Another quipped: "Press that when you are being followed. It deploys a smoke screen that will allow you to disappear in a dramatic fashion. Also a rear fog light."
A third replied: "That looks like a rear fog light switch. If it’s front the lines dip down." Meanwhile, a fourth also commented: "My friend failed her test for not being able to put the fog lights on when the examiner asked so learn where they are guys!!!"
It should be noted that there are different fog light indicators, and they all look a little different. The symbols vary slightly depending on whether the button is for high beam, low beam, front fog lights or rear fog lights.
The one pictured in the post is actually the rear fog light button, and some people were quick to point this out in the comments. A lot of people said they wouldn't be surprised if many Brits were clueless as to what it was.
One chimed in with: "I would guess a very large proportion of 'qualified drivers' don't know this." Another wrote: "Rear fog light, used when visibility is 100 meters or less. You must switch it off when it clears.
"ETA. To the right of the fog switch is a switch that rolls. That’s the brightness of your dash. More importantly, next to that will be another rolling switch with 0-5 on it.
"That is the pitch of your headlights and should always be on zero unless you’re towing something. Back in my youth I sold cars for 13 years. The amount of part exchanges that would come in with that set above zero was astonishing."
