TRENTON, N.J. (AP) — It’s now easier for New Jersey prosecutors to obtain convictions on vehicular homicide or assault by auto charges when drivers kill or injure someone while using a cellphone.

The measure was signed into law Wednesday by Acting Gov. Kim Guadagno, just weeks after it was passed in the state Legislature. It classifies the illegal use of a hand-held cellphone as driving recklessly, one of the factors needed in finding a person guilty of vehicular homicide or assault by auto.
