I am a driver on a restricted license. I have to re-apply every 3 years and I could have my license withdrawn at any time, for any misdemeanour.

My crime is that I drive constantly under the influence of drugs ....in my case insulin as I am a diabetic.

I also have restrictions placed on me with regard to the type and size of vehicles that I am allowed to drive.

In all other respects I am a very competent driver. Even now , although retired, I cover approx 12,000 miles a year, have held a license for over 30 years and have never caused an accident.

I would maintain that I am far safer than many many other drivers, particularly those who knowingly drive while their senses are impaired by drugs and/or alcohol.
