1. The director, upon the receipt of a certified copy of a judgment, shall forthwith suspend the license and registration and any nonresident's operating privilege of any person against whom such judgment was rendered, except as hereinafter otherwise provided in this section and in section 303.130.

2. If the judgment-creditor consents in writing, in such form as the director may prescribe, that the judgment-debtor be allowed license and registration or nonresident's operating privilege, the same may be allowed by the director, in his discretion, for six months from the date of such consent and thereafter until such consent is revoked in writing notwithstanding default in the payment of such judgment, or of any installments thereof prescribed in section 303.130 provided the judgment-debtor furnishes proof of financial responsibility.
