Anyone who knows the A21 between Tonbridge and Tunbridge Wells will know what a treacherous road it is. It's the bit where the dual carriageway goes down to a single lane each way, near Pembury (where we live). There's a steep stretch of hill with a bend half way up.

About half an hour ago, we were driving up Castle Hill on our way home from London. I was asleep in the passenger seat, when I awoke with a jolt as the car braked sharply. Ahead of is a 4 x 4 was ploughing straight into the front of the car in front of us, a Vauxhall Cavalier. Luckily for us, we were about 20 yards behing and managed to stop before we ploughed into the back of the Cavalier. There was glass and debris all over the road. A man got out of the Cavalier, rubbing his leg and grimacing in pain.

As John got out of the car to check that people were OK, I dialled 999. As it turned out - and completely coincidentally - that there was a police car right behind us. I had just got through to the emergency number when it put on its flashing lights.

Why do I bother mentioning this? Mainly because it is yet another example of a very bad accident on a road which has experienced many fatalities over the last few years. Greg Clark has been trying to get the Department of Transport to bring forward plans to dual this mile long stretch of the A21 which were first announced back in 2003.

We're sitting here watching the News at Ten thanking our lucky stars it wasn't worse. But I guarantee there will be more serious accidents on this piece of road this year - probably fatal ones.
