The red mist descends

So, the winter approaches, and suddenly drivers get a chance to use that button on their dashboard. It is *so* frustrating having a feature in their cars, and not being able to activate it whenever they like. And now, they have an excuse to use it, so they *do*.

I’m talking, of course, about the rear fog lamps. These uber-bright lamps are designed to pierce through fog, spray, and so those following you at an inappropriate speed can avoid striking you.

They are so bright that they can obscure brake lights, and I find that they draw the eye in a hypnotic way. This makes them actually rather dangerous. But many people who use them are unaware of this, and switch them on. leave them on, and forget them. The result is that their brake lights may be missed, or other vehicles near their own may be missed by other drivers, which is, of course, rater dangerous.

So, what’s the deal with these? When should you use them? When can you *not* use them?

I visited the UK government web site, which has this page on driving in adverse weather conditions taken from the latest Highway code, which every driver road user should read every few years, certainly when a new edition is published.

It says (and I love this because it says what you must not do:

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.

And, for completeness,

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).

Hopefully the geeks can avoid the cyclic dependencies. But there you have it. If you can see 100 metres, then you should switch off your fog lights. A good rule for rear for lights is: If you can see the headlamps of the car behind you, then he can see your normal lights, and so you should switch off your fog lights. Of course, this suggests that you use your mirror quite a lot, and I’m perfectly sure not everyone does. . .

I have a lot to say on middle-lane hogging, which is at least as bad in Europe as it is in the UK. (In fact, on the M25/M20 to and from Dover, the European drivers are *worse* than the UK ones.) But I’ll save that for another day.
