Expands implied consent law to include blood testing; establishes per se standard for driving under influence of marijuana and certain controlled dangerous substances.

This bill expands New Jersey's implied consent law to require blood testing for drugs, not just alcohol, when police suspect a driver is impaired. It establishes a "per se" standard for marijuana and certain controlled substances, meaning drivers with 3 nanograms or more of THC per milliliter of blood are automatically considered under the influence. For other drugs, any detectable amount of Schedule I, II, or III controlled substances (not medically prescribed) would also constitute a violation. The bill directly affects drivers in New Jersey who may operate vehicles while impaired by marijuana or certain controlled substances, changing how law enforcement can test for drug impairment.
