The police need to be involved only if damage has been caused and drivers' details were not exchanged. If your story is true and the damage was so slight you didn't notice at the time it's probably not an issue, even if it's technically an offence. If you did inform security of your details it shows a willingness to comply anyway.

The chance of your being charged with careless driving or any other motoring offence is slim.

Almost certainly it's now purely an insurance matter.

Nothing really further to add. You've not committed any offence - or at least, I really can't see the CPS ever wanting to try to persue someone through the courts who had shown a genuine attempt to contect the other party.

One question though : have you informed YOUR insurance company. Please do so, and submit full details of what happened - including the fact that the damage was very minor, and photographs of the damage to your car.

It's not unknown for someone to 'try it on' and attempt to get half the panels and a bumper on their car replaced from making out that a minor knock was far more than that.

Yes. Though make it very clear that you are not making a claim, and that these are only being sent so that the damage to the other vehicle can be assessed as being on 'the other side' of the damage on yours.

Sarah, sound advice here especially from Rob. The photographic evidence is important for the reason Rob points out. An exagerated claim may leave the other party open to prosecution themselves if there is strong evidence to disprove their claim. If they work at your institution then maybe you could speak with them and agree to settle a reasonable claim without the need to involve insurance companies. You have done the right thing here and been very responsible, so do not reproach yourself.

Good luck. Concrete
