Statutory provisions

Statutory Provisions: 18 U.S.C. §§ 1112, 1841(a)(2)(C), 2199, 2291, 2332b(a)(1). For additional statutory provision(s), see Appendix A (Statutory Index).

Application Note:

1. Definitions.—For purposes of this guideline:

“Criminally negligent” means conduct that involves a gross deviation from the standard of care that a reasonable person would exercise under the circumstances, but which is not reckless. Offenses with this characteristic usually will be encountered as assimilative crimes.

“Means of transportation” includes a motor vehicle (including an automobile or a boat) and a mass transportation vehicle. “Mass transportation” has the meaning given that term in 18 U.S.C. § 1992(d)(7).

“Reckless” means a situation in which the defendant was aware of the risk created by his conduct and the risk was of such a nature and degree that to disregard that risk constituted a gross deviation from the standard of care that a reasonable person would exercise in such a situation. “Reckless” includes all, or nearly all, convictions for involuntary manslaughter under 18 U.S.C. § 1112. A homicide resulting from driving a means of transportation, or similarly dangerous actions, while under the influence of alcohol or drugs ordinarily should be treated as reckless.
