The bill amends several sections of Chapter 31-27 of the General Laws, which pertain to motor vehicle offenses. Specifically, it increases the penalties for offenses related to driving so as to endanger resulting in death or serious bodily injury, as well as driving under the influence resulting in death or serious bodily injury. The amendments include increasing the maximum imprisonment for "driving so as to endanger, resulting in death" from ten to twenty years and for "driving so as to endanger, resulting in serious bodily injury" from five to ten years. Additionally, the bill increases the maximum imprisonment for "driving under the influence of liquor or drugs, resulting in death" from fifteen to thirty years and for "driving under the influence of liquor or drugs, resulting in serious bodily injury" from ten to twenty years. The fines associated with these offenses are also increased, and the range of license suspension is adjusted.

The bill also repeals the enhanced punishments for subsequent offenses of driving under the influence resulting in death or serious bodily injury and replaces them with a single amended range of sentences and fines. The bill requires that upon conviction, offenders may be required to complete alcohol or drug treatment at their own expense. The act would take effect upon passage, indicating that the new penalties and provisions would be enforceable from the date the bill is enacted into law.
