A wheely flat tyre

I went for my walk and as I was passing through the centre of the village I saw a big haulage lorry with hazzard lights flashing pulling up by the side of the road.

A young lady who was the lorry driver jumped from the cab.  We got talking and she said that her tyre had burst as she passed the level crossing at the entrance to the village. 

At least it didn't cause an accident and the driver was fine. There was the added bonus that it provided me with a blip.
