When I called 999 after my hit-and-run incident, the emergency services operator asked if anyone was injured, and if my car was drivable. I said that, at the moment we are both badly shaken, and that I had no idea if my car was still roadworthy.
If I had said we were both fine and the car definitely not disabled, I doubt if the police would have attended.
When they did arrive, I had to produce my driving documents (fortunately I always carry these with me, otherwise more time would have been involved in going to a police station to produce them), and I was breathalised. That was a "first", which read ZERO, but I understood that these latest units used download the information onto a data base.
The attending police officer was courteous and friendly, so I have no complaints there. The officers at the sharp end are probably always OK; if anything, it's the back-room admin people who are liable to be snotty.
Getting the police to attend in such circumstances as mine is important. Their official paperwork at the scene, plus the display of thoroughness on the part of the victim, seems to have a positive effect on subsequent dealings with the insurers.
Go belt-and-braces, dot every "i" and cross every "t".
If any indication is given that you are burdening officialdom, remember, you are the aggrieved victim, and it wasn't you who created the problem.
If the powers-that-be got to grips with the need to eradicate illegal drivers, we law-abiding ones would be far less likely to suffer these life-threatening incidents on our roads.
