Arizona CDL DUI Attorney

Arizona CDL DUI Laws Explained

Under Arizona law, DUIs are harshly penalized, even for those that do not have a CDL. However, when you have a CDL the DUI laws that pertain to ordinary people apply to you, plus additional penalties. Furthermore, the implications that a DUI has on a CDL are on top of the restrictions that a DUI has on a tradition driving privilege.

1. CDL DUI in Commercial Vehicle

In Arizona, the law differentiates between being cited while driving a commercial vehicle and driving a personal vehicle. The legal limit for those driving a non-commercial vehicle is .08. However, when someone is operating a commercial vehicle as defined by ARS 28-1381A4 the legal limit becomes .04. Nevertheless, both DUI variations can impact a driver’s CDL.

2. CDL DUI in Personal Vehicle

If an Arizona CDL holder is driving a personal vehicle, their DUI limit is the same as that of a non-CDL holder (.08). However, it’s important to remember that just because a CDL holder is in a personal vehicle does not mean that a DUI conviction won’t subject them to a CDL revocation. If convicted, the driver will be subject to the consequences of a regular DUI and extreme DUI. In addition to punishments for the underlying DUI, a CDL holder can expect CDL implications even if the CDL DUI is in a personal vehicle.

What Is CDL DUI in Arizona?

If you hold a Commercial Driver’s License (CDL) in Arizona, whether a Class A, B, or C license, it’s critical to understand that the rules surrounding driving under the influence (DUI) are far stricter for you than for the average driver. At Feldman & Royle, our Arizona CDL lawyer team has seen how even a single mistake can jeopardize a driver’s entire career.

The term “CDL DUI” refers to a DUI offense committed by someone who holds a CDL, regardless of whether the person was operating a commercial vehicle or their own personal vehicle at the time of the arrest.

At its core, a CDL DUI means a DUI violation involving a CDL holder, but the consequences go far beyond a standard DUI, affecting your license, livelihood, and long-term future as a commercial driver. This is why many drivers immediately contact a Phoenix CDL DUI Attorney when facing allegations under Arizona’s CDL DUI laws.

Legal BAC Limits & When CDL DUI Applies

• Driving a commercial vehicle

If you are operating a commercial motor vehicle (CMV) that requires a CDL under state or federal law, Arizona imposes a much lower legal blood alcohol concentration (BAC) threshold. A BAC of 0.04% or higher can lead to a CDL DUI charge. Even a small amount of alcohol can trigger a violation under this standard.

• Driving a personal (non-commercial) vehicle

If you are a CDL holder driving your own non-commercial vehicle, the general legal limit applies, 0.08% BAC. However, a conviction at this level still leads to CDL-specific penalties, including suspension and disqualification.

• Impairment to the slightest degree

Arizona law also permits DUI charges if an officer believes your ability to operate the vehicle is impaired “to the slightest degree,” even if your BAC is below the per se limit. This rule applies equally to CDL holders and commercial vehicle drivers.

Because CDL regulations are tighter and enforcement is stricter, even minimal alcohol consumption well below what a non-commercial driver might register can lead to significant, career-altering consequences. For this reason, CDL drivers facing investigation often turn to an experienced Arizona CDL lawyer to avoid irreversible damage to their driving status.

DUI Penalties for CDL Holder

The penalties of a first time DUI for a CDL holder are similar to those who have a traditional driver’s license. If convicted of a DUI, you can expect:

• Roughly $2000 in fines and fees
• Mandatory substance abuse classes
• A minimum of one day in jail
• A Class 1 Misdemeanor on your criminal record
• At least a 90-day suspension of your Class D license
• Revocation of your CDL (Class A, B, C) for a minimum of one year
• Installation of a Certified Ignition Interlock Device

CDL Disqualification

In addition to other penalties a CDL holder or instructor will have their CDL

CDL DUI Employer Reporting Requirements

Pursuant to mandates set out by the Federal Motor Carrier Safety Administration (FMCSA), a CDL holder is required to notify their employer within 30 days of a convicted for a DUI. This requirement pertains to driver’s regardless of whether they were cited for DUI while they were in a personal or commercial vehicle. Therefore, a CDL holder must report a DUI conviction, even if the motor vehicle hearing is still pending.

Furthermore, a CDL holder must notify their employer if they receive notification that their CDL has been revoked, suspended, withdrawn or disqualified. Notification to the employer must be made before the end of the business day following the day the driver received it. Therefore, a CDL holder must the notice of suspension, even if the CDL DUI is still pending in the criminal courts.

To summarize the reporting requirements of a CDL DUI to an employer, the CDL holder must report:

• A notice of withdrawal, revocation, suspension or disqualification must be reported before the end of the business on the day after receiving the notice.
• A conviction within 30 days

For clarification of these rules or before notifying your employer it is advisable to discuss the particulars of your case with a knowledgeable Arizona CDL DUI lawyer. Revealing too much or too little to your employer may have disastrous results as you are required to maintain and deliver employment records for a 10-year period. Consulting with an expert Arizona cdl attorney before disclosing information to your employer, the court or a prosecutor will ensure that nothing more than is absolutely necessary is recorded in your employment and motor vehicle history.

Arizona CDL DUI Defenses

An Arizona CDL DUI or CDL DWI has the same defenses available as those who have been charged with regular DUI or extreme DUI in Arizona. The difference is simply that a conviction for CDL DUI has an additional consequence of CDL revocation, which will normally have employment consequences. In order to avoid these ramifications, it is important that a CDL DUI lawyer evaluate and develop the strongest defenses possible. Examples of the ways in which a CDL DUI attorney might challenge the State’s case include:

• Attacking the accuracy and administration of roadside tests
• Determining if the person was lawfully pulled over
• Reviewing the probable cause used to effectuate the arrest
• Evaluating whether the vehicle meets the statutory requirements for a commercial vehicle
• Assessing the reliability of the testing device used to obtain a BAC
• Examining whether the State can prove the person actually drove
• Challenging the accuracy of the breath or blood result
• Reviewing Constitutional challenges such as Miranda Violations, to Right to Counsel Violations, and Abuses of Due Process.
