USE OF FOG LIGHTS†††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††
Rule 133 of the current Highway Code states: - 'Use fog lights when visibility is seriously reducedí
This generally means when you cannot see for more than 100 metres (328 ft). You MUST NOT use fog lights at other times'.† Remember to switch them off when visibility improves.
So relating figures to actual distances is not only very important regarding stopping distances, it is very relevant to the above rule.
It can be very irritating when rear fog lights are left on in good visibility.† Naturally they are quite bright and it is not so obvious when the driver is braking. I think some people do genuinely forget to switch them off, (where has their concentration gone?) I think some people put them on as they probably feel more secure and others may feel it keeps tailgaters at bay.
No doubt there are many more reasons why people leave fog lights on; but they may not be aware they are breaking the law.† This could lead to them being pulled up by the police and who knows what that could lead to.
Like I have said, leaving fog lights on is irritating; used correctly, they are an invaluable asset.
