@Matt Bateman.
Entirely my fault.
Driving too fast for conditions, had someone come towards me with main beam on, at night, and was going quicker than I realised.
When he went by me (main beam still on!) I was closer to the t junction than I thought.
Slammed my anchors on. Skidded-in a straight line. Went straight over the t junction (of actually quite a busy road) missed all the traffic and 2 posts, ended up in a little ditch on the other side of the road.
Hit a load of banked up soil.
Stove the bumper in and rippled the bonnet.
The amazing thing is that the following day I took the bumper off, pushed out where I'd stoved it in, reattached it and 'back to blacked' it-you could hardly tell!
Other than the slightly rippled bonnet.
Replaced the tank and cage and back to work in a few days.
That was a Peugeot Expert.
I was very very lucky.
