The registrant of a motor vehicle who deposits cash or securities as provided in this section or in section thirty-four D or the person responsible for the operation of the registrant's motor vehicle with his express or implied consent shall immediately upon the service of any writ or summons in any action the payment of the judgment in which is secured by such deposit, give written notice to the registrar and the state treasurer of the bringing of such action in such form as the registrar may prescribe, and thereupon the registrar may require the giving of a motor vehicle liability bond or policy or may require the deposit of further cash or securities as additional security for the payment of judgments in any other such actions. Whoever fails to give the notice required by this section shall be punished by a fine of not less than one hundred nor more than one thousand dollars or by imprisonment for not more than one year or both.
