VATICAN CITY — The Vatican yesterday issued a “Ten Commandments” for motorists to keep them on the road to salvation, warning drivers against the sins of road rage, abuse of alcohol, or even simple rudeness.

The document, from the Vatican’s office for migrants and itinerant people, warned that automobiles can be “an occasion of sin” — particularly when used to make a dangerous maneuver or when used by prostitutes and their clients.

And it suggested prayer might come in handy — performing the sign of the cross before starting off and saying the rosary along the way. The rosary was particularly well-suited to recitation by all in the car, it said, since its “rhythm and gentle repetition does not distract the driver’s attention.”

Cardinal Renato Martino, who heads the office, told a news conference the Vatican felt it necessary to address the pastoral needs of motorists because driving is such a big part of contemporary life.

The document, “Guidelines for the Pastoral Care of the Road,” laments the ills associated with automobiles: Drivers use their cars to show off; driving “provides an easy opportunity to dominate others” by speeding, and drivers can kill themselves and others if they drink, use drugs, or fall asleep at the wheel.”

THE TEN COMMANDMENTS OF THE ROAD

1. Thou shall not kill.

2. The road shall be a means of communion between people and not of mortal harm.

3. Courtesy, uprightness, and prudence will help you deal with unforeseen events.

4. Be charitable and help your neighbor in need, especially victims of accidents.

5. Cars shall not be an expression of power and domination, and an occasion of sin.

6. Charitably convince people not to drive when they are not in a fit condition to do so. Support the families of accident victims. Bring guilty motorists and their victims together, at the appropriate time, so that they can undergo the liberating experience of forgiveness.

9. On the road, protect the more vulnerable party.

10. Be responsible toward others.
