A couple of weeks ago I had a very minor bump in my employer's car. No big deal.
I did the necessary at the roadside and exchanged details then we both went on our way.
Damage to my car was minor scrape and dent on rear passenger door, and minor scrape on rear wing and bumper. His large Vauxhall van was unmarked as far as I could see.....he may have had some VERY minor paint damage to his front wheel arch but it was hardly noticeable.
I completed the necessary paperwork back in the office and sent it off to the Risk Management section while the car was taken to the body shop.
As far as my employer is concerned, the car was bumped, I've owned up, declared it and the car is fixed. I have no problems at work regarding this incident.

As for fault.....being totally honest - probably mine. I changed lane to my right and hit him. I'll argue that he was travelling far too fast because I checked my blindspot and he wasn't there (I ride a bike so always do a shoulder check regardless of vehicle I'm in). But it would probably be argued that I still moved into him and his speed was/is irrelevant.

That's the background but here's the question......

Would you tell your own car insurance when renewal came round that you had been in a bump??
