The bill amends various sections of the General Laws to increase penalties for drivers involved in accidents that result in injury, serious bodily injury, or death, particularly for those who fail to stop at the scene. Specifically, it raises the maximum imprisonment for accidents resulting in serious bodily injury from 10 to 15 years and mandates a license loss of at least two years, up to a maximum of ten years. For accidents resulting in death, the minimum imprisonment is increased from two to five years, with a maximum of 30 years, and the license revocation period is set to a minimum of five years, with the possibility of permanent revocation. The bill also clarifies the application of these laws to accidents involving pedestrians or bicyclists and updates definitions and penalties to reflect the increased severity of these offenses.

Additionally, the bill introduces new legal language regarding penalties for driving under the influence (DUI) offenses that result in serious bodily injury or death. It increases the maximum imprisonment for DUI resulting in death from 15 years to 30 years and for DUI resulting in serious bodily injury from 10 years to 15 years. The revocation period for a driver's license is modified to a minimum of two years and a maximum of ten years. Convictions for DUI resulting in death will incur mandatory fines ranging from $5,000 to $10,000, while those for serious bodily injury will face fines between $1,000 and $5,000. The legislation aims to create a more uniform and stringent approach to penalties for DUI offenses that lead to severe consequences, thereby enhancing public safety.
