When is the one time you would want to describe your turbo-charged sports car as a rusty old banger? When you're filling out your insurance application, according to Asda Motor Insurance.

Its research shows that more than one in 10 motorists on UK roads is at risk of having a claim turned down because of a lie on their insurance application.

Top of the list of likely fibs is the location of overnight parking, with 11% of motorists claiming that their vehicle is parked on a drive or in a garage overnight, instead of on the street.

And 6% of motorists reduce the value of their cars to reduce the premium. Backchat does not advise this if you drive a Ferrari.
