Obviously I wouldn't want to waste the insurance company's time with little knocks and prangs - we're equally talking car as well as m/bike insurance here.
My grey area is telling my car insurance about my motorcycle accident. They're two very different mediums of transport, as we all know. My method for driving each is equally as different.
So, I think the only porky I've done is not tell my car insurance about my bike slide, afterall, technically no other vehicle was involved. My car record is clean as a whistle nowadays, apart from the humungous fault claim that was a new windscreen after a stone chip
a couple of years ago.
After collecting 6 points in my first couple of years of driving - something that would now have lost me my licence; and having had an accident and a claim (separately) before I was 19, I quickly realised how these things cripple your ability to afford insurance. Since then I tried to be the safest driver I could be.
The points expired long ago, the claims have disappeared from my records, and my licence and general record is now clean. So really I have nothing to lie about, and that's what I wanted to achieve, and how I want it to stay!
