Commercial DUI Lawyer in Tucson

Representing Bus & Commercial Truck Drivers in Tucson, AZ

A driver who operates a bus, a tractor-trailer, a commercial truck or van possess a valid commercial driver’s license (CDL). Originated by the Commercial Motor Vehicle Safety Act of 1986, the issuance of a CDL recognizes the driver’s special training and skills in the safe maneuvering of large, heavy and commercial vehicles. The regulations governing CDLs are intended to protect passengers, other motorists, and the public. Violation of the strict CDL rules concerning drug and alcohol use can result in harsh penalties.

The attorneys at Nesci & St. Louis are 100% dedicated to criminal defense and DUI defense. Our lawyers possess more than 80 years of combined experience in criminal defense trials. We handle the most challenging DUI cases involving commercial licenses, high blood or breath alcohol content (BAC), and serious DUI accidents.

If you have been charged with DUI, then your commercial driver license and your livelihood are at stake. Our Pima County DUI attorneys aggressively challenge the issues to preserve your rights, your liberty, and your job.

Arizona DUI laws that affect commercial drivers

Arizona Revised Statute § 28-1381 sets the legal BAC limit at .04 for commercial drivers — one-half of the minimum legal BAC that applies to other drivers. A commercial driver can also be charged for driving under the influence of drugs. Suspicion of impairment caused by any type of drug — including over-the-counter and prescription medications — can result in a DUI arrest with serious repercussions.

Harsh penalties for Tucson commercial drivers who are convicted of DUI

A conviction for DUI can end your career as a commercial driver. Depending on the circumstances of your charge, conviction can result in incarceration, fines, probation and installation of an interlock device in your vehicle. In addition to punishments other drivers face, you also risk:

  • First Offense — Loss of your CDL for one year
  • Second Offense — Loss of your CDL for life
  • Refusal to Submit to BAC or Drug Tests — Loss of your CDL for life

Challenging blood or breath test results

Your case may hinge on the chemical test – which can be a breath test, a blood test or a urine test. Challenging the reliability and accuracy of chemical test results is a hallmark of our practice. Our DUI attorneys have a reputation for winning victories on highly technical, sophisticated issues involving chemical tests and the machines on which they are performed. Our efforts have resulted in:

  • The suppression by the trial court of all blood test results in 11 felony cases, after the judge found them to be unreliable at the conclusion of a 17-day-long challenge to their admissibility
  • Removal of the Intoximeters RBT-IV® machine from the streets of Arizona
  • Suppression of test results in more than 7,000 cases based on our challenge to the Intoximeters RBT-IV
  • Suppression of test results and dismissal of cases throughout Arizona because of our demand for the CMI Intoxilyzer 8000® source code and software
