Could be anything really. Perhaps she fainted for some reason… I don’t suppose this is the sort of situation she expected she would get such serious injuries though! Hopefully she makes a full recovery.

From the BBC pictures it looked like the truck was sufficiently out of the way. It’s quite an unlikely thing to happen so the positioning of the truck probably isn’t much to fault. The irony is the lift on the truck was probably at her head height in the car for health and safety reasons, since if it was low or flat they might claim it to be a trip hazard to pedestrians!
