After January 1 next no one shall drive a wagon along the streets of Rome or along those streets in the suburbs where there is continuous housing after sunrise or before the tenth hour of the day, except whatever will be proper for the transportation and the importation of material for building temples of the immortal gods, or for public works, or for removing from the city rubbish from those buildings for whose demolition public contracts have been let. For these purposes permission shall be granted by this law to specified persons to drive wagons for the reasons stated. Whenever it is proper for the vestal virgins, the king of the sacrifices, or the flamens to ride in the city for the purpose of official sacrifices of the Roman people; whatever wagons are proper for a triumphal procession when any one triumphs; whatever wagons are proper for public games within Rome or within one mile of Rome or for the procession held at the time of the games in the Circus Maximus, it is not the intent of this law to prevent the use of such wagons during the day within the city for these occasions and at these times. It is not the intent of this law to prevent ox wagons or donkey wagons that have been driven into the city by night from going out empty or from carrying out dung from within the city of Rome or within one mile of the city after sunrise until the tenth hour of the day.
