I think that's WRONG. I hear a lot of people say this and I get fed up with it.
You MUST use headlights when visibility is seriously reduced, generally when you cannot see for more than 100 metres (328 feet). You may also use front or rear fog lights but you MUST switch them off when visibility improves
If it's raining very
hard and there's a lot of spray, you can't see ordinary rear lights unless you are too close for the conditions
. That is dangerous. Conditions like these are like fog. Use rear fog lights when it is really bad and you can see the car in front of you from a safe distance
You should only put the rear fogs on when you're having real difficulty seeing the car in front, even though he has his rear sidelights on - that means the car behind you is having difficulty seeing you as well.
Of course, quite rightly, you MUST turn the fogs off when conditions improve. Otherwise people will
There is no reason to use the front fogs in heavy rain. Infact, they will probably make matters worse for the driver with them on.
EDIT: Looking at the Highway Code, I think it's ambiguously written. Point 226 above is the 1st bullet point under 'Driving in adverse weather conditions'. There are then subsections for driving in heavy rain, snow, fog etc. I take point 226 to be a general
point about visibility in adverse conditions because it appears on its own, not under the other headings - and I personally agree with it.
Under the fog heading, of course, there is mention of foglights. Under the rain heading, there is no mention of lights at all
! And I think we would all agree that in heavy rain you should have lights on. It's badly written.
