The officer measured the light passing through the windows with a machine and informed me that my vehicle was technically "defective".
I informed the officer that I undertook a lot of surveillance as an enquiry agent and that tinting enhances my chances of obtaining evidence.
Nevertheless he told me to have the tints removed or have lighter ones fitted and to contact him when I had completed the work.
Having driven the vehicle for over 12 months I have never encountered a situation, night or day, where my vision has been impaired.
Furthermore, experiments carried out at Loughborough University suggest that window tints have no adverse effect on a driver's vision.
Perhaps the Prime Minister's chauffeur would like to comment on how clearly he can see the police motorcycle outriders through excessive tinting
Finally, when the officer had dealt with me, I put on my sunglasses which allow considerably less light through than the "defective" tints on my vehicle and drove off.
I am still trying to understand the logic behind the fact that you can drive a vehicle with dark sunglasses on but woe betide anyone who drives a vehicle with tints.

Easy to criticise energy plan
Gordon Brown has taken some stick over Labour's plans to help low-paid homeowners to insulate their lofts in the light of swingeing energy price rises, instead of taking more direct
action.
But every little helps, as my granny used to say.
And it does seem unfair when Mr Brown's party have been responsible for introducing pensioners' winter fuel payments as well as other measures to help the elderly, including nationwide free bus travel.
People are always so quick to criticise governments, which is why it is always easier being on the opposition
benches.

Raising awareness of dyspraxia
Being diagnosed with a condition that is practically unheard of by many can make life very hard.
While a lot of your readers probably know about behavioural, social and learning problems such as Dyslexia, ADHD and Asperger Syndrome, I am sure relatively few are familiar with Dyspraxia. Symptoms include difficulties such as walking up and down the stairs, getting dressed, tying shoelaces, forming relationships and an inability to remember more than two or three instructions at once.
It is thought two children are affected in every class of 30 and it is not a condition that you simply grow out of.
However, because it is not an 'obvious' disability, there is a real lack of general understanding.
Since finding out about the condition and the very real implications it can have on daily life for those affected, I am proud to be supporting the Dyspraxia Foundation's national awareness week, Dyspraxia: Making Sense of it All (September 27 to October 4). The campaign seeks to ensure the condition and those affected by it receive recognition and support.
I am urging all readers who suspect that they or a family member may have dyspraxia, or are showing some of the symptoms, to go online to
www.dyspraxiafoundation.org.uk or call the helpline on 01462 454 986.
The charity is also launching a special competition during the awareness week - Reach for the Stars! - for more information see the website above.
