Commercial Drivers and the Strict DUI Laws in Arizona

by Aaron M. Black • April 30, 2021

Commercial drivers navigating tractor-trailer rigs and other large conveyances used in Arizona commerce have a greater expectation for safety because of their vehicles’ missions, massive weight, size, and propensity for participating in serious consequences.

These professional drivers who hold one of three commercial license classes, A, B, or C, may face the end of a career if convicted of driving while impaired.

A conviction for drinking and driving for those who have an Arizona commercial driver’s license means not only a conviction and a criminal record, but also license suspension and in some cases, the Arizona Department of Motor Vehicles will disqualify a commercial driver.

Commercial drivers are held to a more strict level of impairment. Arizona caps a blood-alcohol concentration (BAC) level at 0.04 percent, half of the baseline 0.08 percent for non-commercial drivers. A second DUI conviction means the commercial license is suspended for life.

DUI defendants residing outside of Arizona

For interstate truckers who are convicted for drinking and driving in Arizona, the situation is more difficult. The defendant will serve the sentence in Arizona. Fines are paid to Arizona and cannot be challenged from another state. In DUI cases that go to trial, the out-of-state defendant must return to Arizona for court.

While Arizona residents can be sentenced to jail, they may go to their jobs during the day, returning to the jail after the work day. Drivers from other states will not have that luxury unless they can make such arrangements to serve time in their home state and pay for their own incarceration.

Arizona cannot suspend or revoke an out-of-state commercial license, but a DUI conviction will be reported to the home state’s authorities for action.

Traffic offenses and license suspension, revocation

Commercial driver’s licenses can be suspended and even revoked for multiple serious traffic offenses occurring within three years.

Serious offenses include speeding at 15 miles per hour over the posted speed limit, reckless driving, aggressive driving, texting while driving, and any violation that involves a death.

The Arizona Motor Vehicle Department also considers that driving while the commercial license is suspended or revoked and driving a commercial vehicle without the proper license are considered serious offenses.

For a first DUI conviction, the commercial license will be suspended for a year even if the driver was using their own car, and their regular license will be suspended for 30 to 90 days. A second DUI results in a lifetime commercial license suspension.

Slightly impaired DUI

A commercial driver can be arrested for impaired driving by testing at or above the BAC legal level. Although, Arizona has a zero tolerance policy so drivers can be arrested if they are even “slightly impaired.” The arresting officer makes that determination based on training. Drivers who refuse to take the breathalyzer test will have their license confiscated and suspended.

If the impairment is drug related, Arizona has drug recognition experts (DRE) who undergo training, testing, and certification. They can be called to the traffic stop to conduct testing.

Actual physical control

A commercial driver does not need to be driving to be arrested for DUI. It is sufficient to be in “actual physical control” of the vehicle, a class 1 misdemeanor. Under Arizona Revised Statute §28-1381 ()(1) a person must have access to the vehicle while impaired.

The law as written, does not give definitions but the commercial driver needs only to have “present or imminent” access to the commercial vehicle. A number of facts are considered to determine if actual physical control existed. These factors include:
  • Was the engine running
  • Was the ignition turned on
  • Where was the ignition key
  • Where and in what position was the driver
  • Was the driver awake or asleep
  • Were the headlights on
  • Where was the vehicle stopped
  • Did the driver voluntarily pull off the roadway
  • Was the air-conditioning or heater on
  • Were the windows up or down
  • What was the time of day
  • What were the weather conditions
  • An explanation of the circumstances as determined by the evidence

Arizona’s DUI laws and penalties

Arizona has some of the strictest DUI laws in the nation ranging from misdemeanors to felonies.

A first-time DUI with a BAC of 0.08 is a misdemeanor ranging from 1 day to 6 months in county jail and fines and fees can total up to $1,510.50. A second DUI with a BAC up to 0.15 percent is 6 days to 6 months in jail with a financial penalty of up to $3,468.

A first-time extreme DUI, a misdemeanor, is a BAC above 0.15 percent but less than 0.20 percent and is punished with jail time from 2 days to 6 months with fines and fees totaling $2,760.50. A second extreme offense increases the jail time from 24 days to 6 months with fines and fees totaling $3,718.

A first-time super extreme DUI at a 0.20 BAC percent requires from 3 days to 6 months with fines and fees of $3,218. A second super extreme DUI raises the penalty to 36 days to 6 months in jail and fines and fees totaling $4,633.

Common DUI defenses

A number of defenses for DUI charges are available under Arizona law. These include that the traffic stop was made without probable cause or reasonable suspicion, breath and blood tests results for BAC were faulty, racial profiling, and the arresting officer failed to recite the Miranda rights.
