SB 1257 - Under this act, a person commits involuntary manslaughter if he or she operates a motor vehicle in violation of the "endangerment of a highway worker" statute, and when doing so, acts with criminal negligence to cause the death of a highway worker in a construction zone or work zone. Such crime shall be a class B felony. This act expands the crime of assault of a law enforcement officer, emergency personnel, or probation and parole officer to include highway workers in a construction zone or work zone. This act is similar to HB 1421 (2008). SUSAN HENDERSON MOORE
