SIR - I read your article regarding Roger Smith being fined for incorrect use of fog lights. As a driver of heavy goods vehicles, I drive countless miles in an average year, and see countless other vehicles on the road.

I have also noticed an increasing trend among many drivers to use their front fog lights regardless of any weather conditions. Indeed, many drivers seem almost incapable of deciding when to use lights of any sort and when to switch them off.

Even in the summer months, when there may have been no adverse weather conditions for weeks, I have observed drivers with fog lights, both front and rear, blazing away. I wonder how many would claim to have "simply forgotten to switch them off".

At the other end of the scale is the driver who will merrily zoom along the motorway on a rainy day with only sidelights or, in some cases, without any lights at all . They seem oblivious to the fact that they are almost impossible to see for a HGV due to the rain on the mirrors.

In conclusion, Mr Smith, fog lights dazzle, they do mask braking lights, and incorrect use does cause accidents. Perhaps if you are unsure of the rules of the road I can refer you to rules 201 and 211 of the highway code. If you are still unable to remember to switch off your fog lights perhaps you should exchange your vehicle for a model, such as my own, which automatically switches off all fog lights when main lights are turned off. Thank you.

P BUTCHER,
