NRS 484C.110 – Driving Under the Influence

Nevada Revised Statute 484C.110 defines DUI as driving an automobile while impaired by drugs or alcohol, or with a blood alcohol content (BAC) of 0.08% or higher, or with illegal drug levels in the driver’s blood. Therefore, sober drivers can be convicted of DUI as long as their blood contains unlawfully-high alcohol- or drug levels. An impaired driver can be convicted of DUI even if they have a low BAC and low amounts of drugs in their system.

The full text of the statute reads as follows:

NRS 484C.110. 1. It is unlawful for any person who:
(a) Is under the influence of intoxicating liquor;
(b) Has a concentration of alcohol of 0.08 or more in his or her blood or breath; or
(c) Is found by measurement within 2 hours after driving or being in actual physical control of a vehicle to have a concentration of alcohol of 0.08 or more in his or her blood or breath,
to drive or be in actual physical control of a vehicle on a highway or on premises to which the public has access.

2. It is unlawful for any person who:
(a) Is under the influence of a controlled substance;
(b) Is under the combined influence of intoxicating liquor and a controlled substance; or
(c) Inhales, ingests, applies or otherwise uses any chemical, poison or organic solvent, or any compound or combination of any of these, to a degree which renders the person incapable of safely driving or exercising actual physical control of a vehicle,
to drive or be in actual physical control of a vehicle on a highway or on premises to which the public has access. The fact that any person charged with a violation of this subsection is or has been entitled to use that drug under the laws of this State is not a defense against any charge of violating this subsection.

3. It is unlawful for any person to drive or be in actual physical control of a vehicle on a highway or on premises to which the public has access with an amount of any of the following prohibited substances in his or her blood or urine that is equal to or greater than:

	Urine	Blood
	Nanograms	Nanograms
Prohibited substance	per milliliter	per milliliter
(a) Amphetamine	500	100
(b) Cocaine 150 50	150	50
(c) Cocaine metabolite 150 50	150	50
(d) Heroin	2,000	50
(e) Heroin metabolite: (1) Morphine (2) 6-monoacetyl morphine 1	2,000 10	50 10
(f) Lysergic acid diethylamide	25	10
(g) Methamphetamine	500	100
(h) Phencyclidine	25	10

4. For any violation that is punishable pursuant to paragraph (c) of subsection 1 of NRS 484C.400, it is unlawful for any person to drive or be in actual physical control of a vehicle on a highway or on premises to which the public has access with an amount of any of the following prohibited substances in his or her blood that is equal to or greater than:

	Blood
	Nanograms
Prohibited substance	per milliliter
(a) Marijuana (delta-9-tetrahydrocannabinol)	2
(b) Marijuana metabolite (11-OH-tetrahydrocannabinol)	5

5. If consumption is proven by a preponderance of the evidence, it is an affirmative defense under paragraph (c) of subsection 1 that the defendant consumed a sufficient quantity of alcohol after driving or being in actual physical control of the vehicle, and before his or her blood or breath was tested, to cause the defendant to have a concentration of alcohol of 0.08 or more in his or her blood or breath. A defendant who intends to offer this defense at a trial or preliminary hearing must, not less than 14 days before the trial or hearing or at such other time as the court may direct, file and serve on the prosecuting attorney a written notice of that intent.

6. A person who violates any provision of this section may be subject to any additional penalty set forth in NRS 484B.130 or 484B.135.

Legal Analysis

NRS 484C.110 defines the Nevada crime of driving under the influence as either:

• Driving a motor vehicle with a BAC of 0.08% or higher (even if the driver is unimpaired);
• Driving a motor vehicle with unlawful blood levels of certain drugs (even if the driver is unimpaired); or
• Driving a motor vehicle while impaired by alcohol or drugs (even if the driver has legal blood levels of alcohol or drugs).¹

In DUI of drug cases, it is not a defense that the drug was a prescription medication that the defendant’s doctor prescribed him/her. And in DUI of marijuana cases, it does not matter that Nevada now allows adults 21 and older to possess up to one ounce of marijuana in private. Being impaired by any drug while operating an automobile qualifies as DUI in Nevada.

But in DUI of alcohol cases, it is a potential defense that the defendant consumed alcohol after he/she stopped driving but before getting arrested and taking the evidentiary breath test or a blood test – thereby causing high BAC results.²  Note that if DUI defendants refuse evidentiary breath or blood testing following their arrest, the police can obtain a warrant and administer a blood draw against their will.³
