A chipped windscreen may be a common complaint for motorists but some of the explanations given for the damage, from an irate mother-in-law to a falling squirrel, are far from usual.
Glass repair firm Autoglass has released a list of the most outlandish explanations given to them by drivers complaining of cracked windscreens in 2010.
One caller said his mother-in-law had taken a baseball bat to his car following a family row, and in the case of the squirrel, the animal had fallen from a tree and landed on a car's windscreen, shattering the glass.
Requests for help were also received from a driver whose window was shattered by a startled deer and another who claimed a farmer had taken an axe to his windscreen in a row over parking.
Matthew Mycock, managing director of Autoglass, said the technicians "never cease to be amazed" by some of the explanations given.
He added: "While the most common cause for damaged glass comes from other cars throwing up loose chippings from the road, our customers have offered a whole host of weird and wonderful explanations."
Other examples of strange causes of cracked windscreens include the heel of a woman's stiletto chipping the inside of a window and an unidentified item falling from a plane onto a car.
