Hello Yorkie, that's what I was thinking, if you as a motorist take reasonable care to ensure the car is in a roadworthy condition by checking tyres, lights, etc, before setting out, I cannot see how they can convict you for something that is 100% outside your control. I feel sure that at some stage someone with money will challenge this and hopefully get the law changed. I am all for ensuring compliance, especially where safety is concerned, but common sense needs to be used firstly by those charged with legislating and secondly, by those enforcing the laws.
