Walk quietly and carry a crowbar.

The terrible crash on the M5 reminded my that after 20 years working for newspapers I have photographed a number of crashes.

But since I parking my precious Lotus Europa upside down near Newton Abbot nearly 40 years ago.

I realised the importance of have to right stuff in the car to rescue trapped drivers.

Though the standard kit for photographers includes the florescent jacket (always useful if you have to change a Tyre at night) I also carry a full size crowbar.
One of the first thing fire crews do in a car crash is open the bonnet and disconnect the battery to prevent fire.
Though one day I may be stopped for going equipped for burglary I think its worth the risk.
