Offense. - A person commits the offense of impaired driving in a commercial motor vehicle if he drives a commercial motor vehicle upon any highway, any street, or any public vehicular area within the State: While under the influence of an impairing substance; or After having consumed sufficient alcohol that he has, at any relevant time after the driving, an alcohol concentration of 0.04 or more. The results of a chemical analysis shall be deemed sufficient evidence to prove a person's alcohol concentration; or With any amount of a Schedule I controlled substance, as listed in G.S. 90-89, or its metabolites in his blood or urine. A person who has submitted to a chemical analysis of a blood sample, pursuant to G.S. 20-139.1(d), may use the result in rebuttal as evidence that the person did not have, at a relevant time after driving, an alcohol concentration of 0.04 or more. In order to prove the gross vehicle weight rating of a vehicle as defined in G.S. 20-4.01(12f), the opinion of a person who observed the vehicle as to the weight, the testimony of the gross vehicle weight rating affixed to the vehicle, the registered or declared weight shown on the Division's records pursuant to G.S. 20-26(b1), the gross vehicle weight rating as determined from the vehicle identification number, the listed gross weight publications from the manufacturer of the vehicle, or any other description or evidence shall be admissible. Defense Precluded. - The fact that a person charged with violating this section is or has been legally entitled to use alcohol or a drug is not a defense to a charge under this section. Defense Allowed. - Nothing in this section shall preclude a person from asserting that a chemical analysis result is inadmissible pursuant to G.S. 20-139.1(b2). Pleading. - To charge a violation of this section, the pleading is sufficient if it states the time and place of the alleged offense in the usual form and charges the defendant drove a commercial motor vehicle on a highway, street, or public vehicular area while subject to an impairing substance. Implied Consent Offense. - An offense under this section is an implied consent offense subject to the provisions of G.S. 20-16.2. Punishment. - The offense in this section is a misdemeanor and any defendant convicted under this section shall be sentenced under G.S. 20-179. This offense is not a lesser included offense of impaired driving under G.S. 20-138.1, and if a person is convicted under this section and of an offense involving impaired driving under G.S. 20-138.1 arising out of the same transaction, the aggregate punishment imposed by the Court may not exceed the maximum punishment applicable to the offense involving impaired driving under G.S. 20-138.1. Repealed by Session Laws 1991, c. 726, s. 19. Chemical Analysis Provisions. - The provisions of G.S. 20-139.1 shall apply to the offense of impaired driving in a commercial motor vehicle. History (1989, c. 771, s. 12; 1991, c. 726, s. 19; 1993, c. 539, s. 363; 1994, Ex. Sess., c. 24, s. 14(c); 1998-182, s. 24; 2006-253, s. 10; 2010-129, s. 1.) Editor's Note. - Session Laws 1987 (Reg. Sess., 1988), c. 1112, s. 15 also enacted a G.S. 20-138.2 , to be effective June 1, 1989 through June 30, 1989, which was almost identical to the G.S. 20-138.2 enacted by Session Laws 1989, c. 771, s. 12, effective September 1, 1990. Session Laws 1989, c. 771, s. 18, effective June 1, 1989, repealed Session Laws 1987 (Reg. Sess., 1988), c. 1112; therefore, G.S. 20-138.2, as enacted by c. 1112, never went into effect. In subsection (a2) above, "G.S. 20-4.01(12f)," was substituted for "G.S. 20-4.01(12e)," to conform to renumbering in G.S. 20-4.01 , as amended by Session Laws 2010-129, s. 1. Effect of Amendments. - Session Laws 2006-253, s. 10, effective December 1, 2006, and applicable to offenses committed on or after that date, added the last sentence in subdivision (a)(2), added subdivision (a)(3) and subsections (a1), (a2) and (b1).
