If you are a truck or bus driver in Nevada, you face commercial DUI charges for driving with a blood alcohol content (BAC) of 0.04% or higher. This is a much stricter drunk driving standard than for non-commercial drivers, who face DUI charges for driving with a BAC of 0.08% or higher.

Therefore, a commercial driver can be convicted of drunk driving with a 0.07% BAC when a non-commercial driver with the identical BAC could go free.

A first-offense commercial DUI in Nevada is a misdemeanor. The punishment includes:

•  2 days to 6 months in jail,
• $400 to $1,000 in fines,
• a victim impact panel,
• DUI School,
• a 1-year CDL suspension, and
• a 185-day regular driver’s license suspension.

The following graph compares the BAC thresholds for commercial drivers, non-commercial drivers, and under-21-year-old drivers.

In this article, our Las Vegas DUI lawyers answer the following question:

• 1. What if my BAC is below 0.04%?
• 2. What are commercial vehicles?
• 3. What are the penalties?
• 4. Will I lose my CDL?
• 5. Will I lose my regular driver’s license?
• 6. Can I beat the charges?

1. What if my BAC is below 0.04%?

If you have a BAC of lower than 0.04%, you could still get arrested for commercial DUI in Nevada as long as you are impaired by alcohol or drugs.¹ However, it is difficult for prosecutors to prove you are drunk or high when your blood levels are legal.

In cases where you are not impaired but do have some alcohol in your system under 0.04%, a law enforcement officer may issue you a 24-hour order to stay off the road.

Note that you are prohibited from driving a commercial motor vehicle if there is any trace of drugs in your blood, even if you are unimpaired.²

NRS 484C.120 makes it a misdemeanor to drive a commercial vehicle with a BAC of 0.04% to less than 0.08%.

2. What are commercial vehicles?

Commercial motor vehicles (CMVs) in Nevada comprise most trucks, buses and shuttles. Specifically, a CMV is any motor vehicle used in commerce to transport passengers or property if the vehicle:

• has a gross combination weight rating of 26,001 or more lbs. (includes a towed unit with a gross vehicle weight rating of over 10,000 lbs.);
• has a gross vehicle weight rating of 26,001 or more lbs.;
• is designed to transport 16 or more passengers including the driver; or
• is used in the transportation of hazardous materials.³

3. What are the penalties?

As the following table shows, the penalties for violating NRS 484C.120 increase with each successive conviction.

Penalties may be as much as doubled if the incident took place in a work zone.⁴

4. Will I lose my CDL?

In Nevada, a first-time commercial DUI carries a one-year CDL suspension. Though if you were transporting hazardous materials at the time, the suspension period lasts for three years.

Meanwhile, a second-time commercial DUI causes your CDL to be revoked for life. There is no chance for a license reinstatement. If you are a career truck driver, this would cause you to lose your livelihood.

Note that you face the same suspensions described above even if:

• you get arrested for a non-commercial DUI in a non-commercial vehicle, and/or
• you refuse to submit to a chemical test of your breath or blood following any DUI arrest.⁵

Contesting a Driver’s License Suspension

The only way to avoid a CDL suspension is to win both your criminal DUI case and the administrative DMV case, which are totally separate proceedings. The DMV case consists of a DMV hearing, which is like a mini-trial where you (or your attorney) fight the license suspension.

In practice, DMV hearings are difficult to win: Whereas criminal trials require prosecutors to prove guilt beyond a reasonable doubt to get a conviction, the DMV can revoke your license based on hardly any evidence. Still, DMV trials are worth doing since they serve as a “dry run” for the criminal case.

A first-time commercial DUI conviction triggers a 1-year CDL suspension.

5. Will I lose my regular license?

If you get your CDL suspended in Nevada, your non-commercial driver’s license gets suspended as well, as the following table shows.

Note that you may be able to resume driving on your non-commercial license right away if you install an ignition interlock device in your vehicles.⁶

As discussed in the prior section, you may keep both your CDL and non-commercial licenses if you win both the criminal case as well as the DMV hearing.

6. Can I beat the charges?

Here at Las Vegas Defense Group, we have represented literally thousands of commercial drivers charged with DUI. In our experience, the following ten defenses have proven very effective with prosecutors and judges:

1. You were not intoxicated but rather exhausted from driving. Plus your tiredness mimicked symptoms of being inebriated or high.
2. The automobile was not actually a commercial vehicle.
3. You were experiencing a medical episode that resembled being drunk, such as a seizure or diabetic coma.
4. You had dental work such as a bridge that may have caused mouth alcohol to pool, causing an inaccurately high breath test result.
5. You suffered from acid reflux, auto-brewery syndrome, or another medical condition that caused your breath sample to register high blood alcohol concentration levels.
6. The police lacked reasonable suspicion to make the initial traffic stop.⁷
7. The police failed to give proper instructions for the field sobriety tests.
8. The police had no probable cause to make the arrest.
9. The police did not administer the breathalyzer test correctly, or the device was defective.
10. Your blood test samples became contaminated.

Another potential defense is that fumes from the truck or bus seeped into the vehicle, causing you to become impaired without your knowledge. If we can show that this was due to a defect of the vehicle that you had no control over, the prosecutor may be willing to reduce or dismiss the charge.

Plea Bargains

If the state refuses to dismiss your commercial DUI charge, it may be willing to reduce it to reckless driving (NRS 484B.653) as part of a plea deal. Reckless driving carries only a two-month CDL suspension for a first offense.⁸
