why do drivers do it all the time

[henryandlesley]

Why do other drivers always have their front fogs and rear fogs on dont drivers know what the word FOG means i just went out and it was snowing heavy and every other car had their fog lights on why i ask it is not foggy cant people know what it means then they dont like it when i put all 8 lights on the roof and my head lights on full beam with 2 hugh big spots on the nudge bar on and they cant see how i look at it if i cant see due to their fog lights then i will make then not see where is the police now adays stopping drivers driving arround with the fogs on and giving them a fixed fine for it

  Fog lights are to be used in poor driving conditions like spray heavy snow or  fog  chances are police would fine you for using roof light on public road

The law says you can use fog lights in conditions of fog or falling snow when visibility is reduced to 100meters or less.  Top tip then, if I can read the number plate of the car ahead chances are I don't need a fog light to tell me it's there :roll:

Personally i think the law should also make it so that fog lights cancel automatically when the lights or engine get turned off, doubtless we will be seeing fog lights left on for a few days now

 :) There is no law stopping you buying or fitting roof lights but they must only be used for off use only at my last mot i had to disconnect mine before guy whould pass car

 I do believe that is case (Certainly in EU) and probably has been for rear fog Lights since at least 2001 I think that also includes fronts.

I always thought it would be better for a buzzer to keep screaming the word "FOG!!!" at you if you were doing more than 20mph with the fog lights on,  if you really need them you shouldn't be driving quickly :)

Not spray but you are right on the other 2 points.

About the spot lights on the roof bar, as someone else said, you are allowed to buy them, fit them, and use them offroad. The law is quite clear on what you can and cannot display re: lighting.

I have completed my Advanced driving test with the police and I was told to use my 6 hella roof lights as its giving a safer drive. The same rule with main beam and they should be linked to the stalk to turn both out togerther if you have dwellings or oncomming vehicles.

That was a police officer that told me that.

never had a problem with my rooflights when in for mot  :-k

Its an urban myth dating back to some pretty old lighting laws that says roof lights are illegal.

There used to be a maximum height of 42" for main beam and "auxillary main beam lights" (no such thing as spot lights in law) but there no longer is - likewise the max height for fog lights used to be 24" but this too has been relaxed to 1200mm (higher than the old spot light max height)
