DUI Defense for Commercial Drivers from Attorneys with More Than 40 Years of Combined Experience

Representing bus, tractor-trailer and commercial truck drivers in Tucson, Arizona

A driver who operates a bus, a tractor-trailer, or a commercial truck or van must obtain a commercial driver license (CDL). Originated by the Commercial Motor Vehicle Safety Act of 1986, the issuance of a CDL indicates the driver’s special training and skills in the safe maneuvering of large, heavy 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.

Arizona DUI laws that affect commercial drivers

Arizona Revised Statute section 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. Impairment 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
