Driving under the influence (DUI) in Nevada is a serious criminal offense governed primarily by Nevada Revised Statutes (NRS) Chapter 484C. From the moment of arrest to trial and sentencing, strict laws protect public safety and hold offenders accountable. In Las Vegas, where nightlife and tourism are prominent, DUI cases are common yet complex, requiring experienced legal defense.
If you are facing a DUI arrest in Clark County, understanding your rights, the role of the Nevada Department of Motor Vehicles (DMV), and the legal process is essential. This guide from Gallo Criminal Defense Las Vegas breaks down the DUI process, from arrest to potential trial, and how expert legal help can protect your future.
DUI Investigations Typically Start With a Traffic Stop and Field Tests
Most DUI arrests begin with a traffic stop when law enforcement observes signs of impairment such as reckless driving, weaving, or failure to obey traffic laws. Officers will request your driver's license, registration, and proof of insurance while assessing signs of intoxication, including:
- Slurred speech
- Bloodshot eyes
- Odor of alcohol
- Delayed responses
- Presence of open containers in the vehicle
If suspicion arises, officers may administer field sobriety tests such as the walk-and-turn, one-leg stand, or horizontal gaze nystagmus tests. Although these tests help officers determine impairment, they are not foolproof and can be legally challenged.
Note: Refusing to perform field sobriety tests is allowed and does not carry a penalty, but refusal can be used as evidence against you in court. (See State v. Wright, 130 Nev. 470 (2014).
Chemical Testing Confirms Impairment Through BAC Measurements
After field tests, drivers are asked to submit to chemical testing to measure Blood Alcohol Concentration (BAC). Nevada law prohibits operating a vehicle with a BAC of:
- 0.08% or higher for regular drivers
- 0.04% or higher for commercial drivers
- 0.02% or higher for drivers under 21
Testing may include breath, blood, or urine tests. Under Nevada's implied consent law (NRS 484C.440), refusal to submit to chemical testing results in automatic administrative license suspension, typically for 180 days on a first offense. You must request a DMV hearing within 7 days of arrest to contest this suspension. Failure to do so results in automatic loss of the right to challenge the suspension.
If you refuse a test, police may seek a warrant to draw blood forcibly, respecting constitutional protections against unlawful searches. This evidence is crucial in court.
The Arrest Includes Booking, Bail, and Jail Time
After arrest, you will be taken to a detention facility for booking, where you will undergo fingerprinting, photographing, and a property inventory. You enter the criminal record system at this stage.
Bail eligibility depends on the severity of the offense and prior convictions. For felony DUI charges or misdemeanor DUI involving injury, you may remain in jail until a court hearing.
DUI Charges Are Filed Based on Severity and Prior Convictions
Charges filed by prosecutors depend on evidence and history, typically as follows:
First DUI Offense (Misdemeanor):
- Up to 6 months in jail
- Fines of $400–$1,000 plus court costs
- Mandatory DUI school
- Driver's license suspension for 185 days (court suspension) plus 180-day DMV suspension (administrative)
- Community service and victim impact panel
Second DUI Within 7 Years (Misdemeanor):
- 10 days to 6 months in jail
- Up to $1,000 in fines
- Mandatory substance abuse treatment
- Ignition interlock device required
- One-year license revocation
Felony DUI:
- Third offense, DUI causing injury or death, or prior felony conviction
- Imprisonment for 1 to 20 years
- Substantial fines
- Long-term license suspension
- Mandatory ignition interlock device
The Arraignment Marks the Start of the Court Process
At arraignment, the judge formally reads charges, and you enter your plea. It is risky to appear without a lawyer—an experienced DUI attorney can negotiate bail, motions, and plea agreements.
Pre-Trial Motions, Hearings, and Evidence Challenges Follow
Attorneys often file motions to suppress unlawful evidence, dismiss charges, or challenge the accuracy of tests. These motions can improve your chances for favorable plea deals or even dismissal.
Trials Are Sometimes Necessary for Complex or Contested DUI Cases
If no resolution is reached, the case proceeds to trial, which includes jury selection, witness testimony, and cross-examination. Flaws in testing or procedure can create reasonable doubt.
Sentencing Includes Multiple Penalties Based on the Offense
Convictions can result in:
- Fines and court costs
- Probation or jail time
- Loss of driving privileges
- Mandatory treatment, DUI school, or counseling
- Ignition interlock device installation
- Victim impact panel attendance
Penalties increase for high BAC levels, injuries, or the presence of minors.
The DMV Process Runs Separately From the Criminal Case
The DMV conducts independent administrative hearings. A license suspension by the DMV can occur regardless of the outcome of a criminal case. Requesting a hearing within 7 days is critical.
DUI Convictions Can Affect Employment, Insurance, and Life Plans
Consequences extend beyond court fines, including increased insurance premiums, employment challenges, professional license revocations, and social stigma.
