Yes.

They should only be used on certain types of road (plus other
conditions), not for example in towns etc. Therefore you don't
need them when the engine is off!

Is there actually any prohibition from using them on certain types
of road. I though the only rule was the obvious one of "turn off
rear fog lights when the following car is so close that it will be
dazzled by them"?


Oh dear....

Rather than tutting, perhaps you'd like to point me to the exact
regulations. OK, so I omitted to say "only use them when it's
foggy", because I thought that was blindingly obvious, though many
people seem to use them even when it's completely clear (not even
light mist).

Is there something in the highway code about classes of road or its
speed limit which regulates when they may or may not be used,
despite thick fog, subject always to the "don't dazzle" rule.

Rule 226 of the Highway Code says don't dazzle when using fog lights.
It's safe to assume you are more likely to dazzle when using fog
lights in town and thus in close proximity to other cars than when on
rural roads and from their think fog lights are not to be used in
such conditions.

I do not see why it is "safe to assume" any such thing.Â* I have driven
in various parts of London (including within Westminster and the City)
when there was fog dense enough to justify the use of rear fog lights.

In addition there is no "don't dazzle" rule as such.Â* Rule 226 simply
states:

"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 is probably what you have in mind:

"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."

But note that doesn't /forbid/ dazzling other road users.Â* It admits
the possibility that you will dazzle someone a metre behind you for
the sake of them seeing you in time to stop a metre behind you.

The point is also explicit in the underling statute where regulation
27 forbids use of a rear fog lamp:

"Used so as to cause *undue* dazzle or discomfort to the driver of a
following vehicle." [emphasis added]




Yes, 236. I was dazzled by some **** with his fog lights on when typing.
your chebs are enough to dazzle anybody chebs ....
