I know this has been covered pretty much ad nauseum, but if a driver uses fog lights (town driving) when it's not foggy, does this obscure his close-up vision?

It's not a facetious question since I've read about how lights react with atmosphere; spreads (or not), but comments generally referred to fast driving on motorways or unlit B roads.

I wouldn't have thought it would obscure vision unless there is mist/particles in the air that it could reflect off (and even then, this is the environment they are designed to be used in so wouldn't make too much difference). If it's extremely bright it could wash out detail in theory. But no one uses fogs in the daylight.

I think mainly if used at low speeds it could obscure other road users vision, rather than the car using the fogs.

Thanks Mort

By way of explanation, I saw someone with fog lights on this morning (daylight, not foggy) who almost ran someone over on a zebra crossing and I couldn't understand how he could not have seen the person, unless it was because of his fog lights in some way. I guess he was just a bad driver.

Many thanks - I guess it's just best to watch out for bad fog-light drivers.

Thanks again

Maybe they know the person and the lights were to help them see them?

Some people are vindictive?

:orb_angry Dont get me 'off on one ' again!!

:orb_no_no Its illegal and for good reasons. Yes. Vision is one of them. The other is blinding other motorists!!

If you can't see without having your fogs on .....Shouldn't be driving...."Shoud have gone to Spec savers"

It may do if I spank him on the nose for having them on!

Why oh why do people do it? It doesn't make them look good, it makes them look like a w*^&%*! Don't get me started...

No it probably doesn't obscure his vision, it probably helps, but to the detriment of all other road users!:thumbdwn:

I can see no reason why the fog lights would in any way obscure a drivers vision on a clear day. The whole idea of them is to provide a low level light to illuminate the kerb close to the car in poor visibility, when main beams would bleach out the road ahead. Driving with them on in clear weather is illegal. many tw@ts drive with them on around here. Thing is, they really make no difference to visibility as the pattern only reaches a few feet in front of the car. Solution: death penalty for incorrect use.

The reason the guy nearly knocked over a pedestrian is obvious. He knows so much about driving he has his fogs on in clear weather. Obvoiusly some kind of **** that does not care about other road users, so probably cant be bothered to look out for them. Might even have been on the phone! Bless him:mad:

I do learn a huge amount from here.
