Fog lights are for use in fog or falling snow only as are rear "high intensity" lights. Using either in heavy rain is unhelpful.

But rain is not all bad; it lubricates your tyres and makes them last longer!!!

I think it was 1952 the great London smog - as Jimbo says it was so thick you literally could only see a yard or two through the thick yellow mist. Breathing through a handkerchief rendered it black with soot. Thousands died of respiratory disease and it heralded the introduction of the clean air act. MY 09 GS manual in Lago Grey, Wood Co arm rest and side bumper strips - now sold.

No thought for anyone else, doesn’t matter if it’s day or night, on many vehicles they still dazzle other motorists with the spray, that’s why it is an offence to use them in the rain. p****d off with a Digital Keyboard Warrior

I DO constantly THINK about the safety of myself and other drivers, how do you know otherwise?

The rule says
Rule 226. 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 (see Rule 236).
Rule 236
You MUST NOT use front or rear fog lights unless visibility is seriously reduced (see Rule 226) as they dazzle other road users and can obscure your brake lights. You MUST switch them off when visibility improves.

I see no mention of the offence of driving with lights on in the rain.

I am greatly influenced in my decisions by advice I gained on a Defensive Driving Course, run by my firm, which had an ex-police instructor for both the classroom and practical parts.

It is an offence to dazzle other road users though.
If the spray is so bad, ever thought of lifting your right foot
You actually make yourself harder to see with your rear fogs on in the rain, the glare causes other drivers to look away from you, they also mask your brake lights.
I suspect your one of the drivers that when in a line of traffic on the motorway with their rear fogs on, drivers further back every now and then see one of your rear fogs appear, think it’s brake light causing them to brake, then the next one, then the next one and so on. p****d off with a Digital Keyboard Warrior

I also find that the colour of the car has an influence on how well it can be seen in heavy rain. Grey/silver cars are especially difficult to see unless they have their rear fog lights on.

You will see that I am talking about daytime with poor visibility and being seen. At night, normal rear lights should be sufficient in heavy rain.

As I said previously, I got a lot of my ideas from attending a Defensive Driving Course, which was aimed at safer driving and lower insurance costs/ repair bills for my firm. It was very informative and made me think about how I drove.

I can't tell from the forum where you live or drive, but I expect that someone does a similar course somewhere near you.

Try booking yourself on one, if they are still available, they are quite interesting, especially the practical driving bit.

PS My course was not about driving slowly, and included how to make progress safely in normal traffic flows. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

How does that make your car easier to see ?
I'd have thought the last thing you want is someone suddenly slowing down without their brake lights coming on when visibility is so poor judging other cars' speed is difficult.

However Im probably being pedantic and you mean people should just drive at reduced speeds in bad weather as the time you have to take avoiding measures is much reduced - this I totally agree with.

Why does this remind me of Michael Schumaker and David Coulthard ?

With decent tread you will aquaplane at 9 x sq root of your tyre pressure. those towing heavy trailers or caravans will find that the the trailer or van won't aquaplane at legal limits due to much higher tyre pressures. my PC is slightly to the right of Genghis
