What is the consequence of 14-223(b)** and 14-236

Any person who violates this subsection shall be guilty of a class A misdemeanor, except that, if such violation causes the death or serious physical injury, as defined in section 53a-3, of another person, such person shall be guilty of a class C felony, and shall have such person's motor vehicle operator's license suspended for one year for the first offense, except that the Commissioner of Motor Vehicles may, after a hearing, as provided for in subsection (k) of section 14-111, and upon a showing of compelling mitigating circumstances, reinstate such person's license before the expiration of such one-year period. For any subsequent offense such person shall be guilty of a class C felony, except that if any prior offense by such person under this subsection caused, and such subsequent offense causes, the death or serious physical injury, as defined in section 53a-3, of another person, such person shall be guilty of a class C felony for which one year of the sentence imposed may not be suspended or reduced by the court, and shall have such person's motor vehicle operator's license suspended for not less than eighteen months nor more than two years, except that said commissioner may, after a hearing, as provided for in subsection (k) of section 14-111, and upon a showing of compelling mitigating circumstances, reinstate such person's license before such period.   The consequences are right there in the statute unless you are asking what the consequences of having a class C felony or class A misdemeanor?
