I had a car accident on the way home from work this evening. Pulled up at a roundabout and the car behind me didn't stop. Bang, rear-end shunt.

Fortunately a Highways Agency vehicle happened to pass by a minute or two later, and took charge smoothly. The other driver and I were both totally calm, but also totally dithering because we didn't really know what to do next. We knew we had to exchange details, but neither of us was quite sure what else if anything had to be done.

I think I'm personally OK, though I'll go to a doctor tomorrow to make sure. I'm less convinced that my car will recover…
