C. A first or second offense of violating this section shall constitute a Class 1 misdemeanor. A third or subsequent offense shall constitute a Class 1 misdemeanor punishable by a minimum, mandatory term of confinement in jail of ten days which shall not be suspended in whole or in part. However, the court shall not be required to impose a minimum, mandatory term of confinement in any case where a motor vehicle is operated in violation of this section in a situation of apparent extreme emergency which requires such operation to save life or limb.

In addition, the court shall suspend the person's driver's license for the same period for which it had been previously suspended or revoked when the person violated this section.

D. In the event the person has violated this section by driving during a period of suspension or revocation which was not for a definite period of time, the court shall suspend the person's license, permit or privilege to drive for an additional period not to exceed ninety days. Any additional suspension ordered under the provisions of this section shall commence upon the expiration of the previous suspension or revocation unless the previous suspension or revocation has expired prior to the ordering of an additional suspension or revocation.
