The Vatican has issued a set of "Ten Commandments" for drivers, urging motorists not to kill, not to drink and drive, and to help fellow motorists in the case of accidents.
The 36-page "Guidelines for the Pastoral Care of the Road" contains 10 Commandments covering everything from road rage, respecting pedestrians, keeping a car in good shape and avoiding rude gestures while behind the wheel.
It also states that cars must not be used as a place of sin, or as an "expression of dominance and power".The document says: "Cars tend to bring out the 'primitive' side of human beings, thereby producing rather unpleasant results."
It appealed to what it called the "noble tendencies" of the human spirit, urging responsibility and self-control to prevent the "psychological regression" often associated with driving.
One part of the document, under the section "Vanity and personal glorification", will not go down well with owners of Ferraris in motor-mad Italy.
