Civil Code, Art. 2184

In motor vehicle mishaps, the owner is solidarily liable with his driver, if the former, who was in the vehicle, could have, by the use of the due diligence, prevented the misfortune. It is disputably presumed that a driver was negligent, if he had been found guilty of reckless driving or violating traffic regulations at least twice within the next preceding two months. If the owner was not in the motor vehicle, the provisions of article 2180 are applicable. (n)
