MAY I remind fellow motorists that fog lights are just that - for use in foggy conditions.

I am fed-up with driving behind people who think they are safer by having these lights on at other times.

Don't they realise that these very bright lights mask their dimmer brake lights, so it is harder to see when they are slowing down.

This is particularly dangerous on the motorways where we don't leave sensible gaps between vehicles at the best of times.
