Most 911 calls about a weaving big rig end with the caller giving a mile marker and hanging back. This one ended with the caller holding the keys.
Arizona DPS says that on Thursday, Nov. 5, dispatch got a call about a semi that couldn’t stay in its lane on Interstate 40 near Flagstaff. The same caller then reported that the truck was blocking an I-40 off-ramp and that the driver “was highly intoxicated.” According to DPS, the caller then pulled the driver out of the cab and took the keys.
When troopers arrived, they ran field sobriety tests and saw signs of impairment. A preliminary breath test came back at 0.301. Troopers also found alcohol in the cab; the agency’s photo shows a can of peach Twisted Tea. The driver was arrested for DUI, and the truck and trailer were towed and placed on a 20-day impound. DPS hasn’t publicly named the driver or the carrier.
Checking DPS’s Math
DPS described the reading as nearly eight times the commercial limit. The exact figures: 0.301 is 7.5 times the 0.04 federal threshold, and 3.76 times the 0.08 limit for ordinary drivers. DPS rounded up, but either way the number is very high.
A caveat: that 0.301 is a roadside screening number. Arizona’s extreme-DUI law looks at alcohol concentration measured within two hours of driving or control, so the case will depend on the evidentiary breath or blood test. If that result also comes in at 0.20 or above, the driver falls into Arizona’s harshest DUI category. www.azleg.gov
Every Rulebook in Reach Has Something to Say
Arizona criminal law. Under the state’s extreme DUI statute, a first offense at 0.20 or higher means at least 45 consecutive days in jail. The money adds up too: at least $500 in fines, plus a $250 assessment and two $1,000 assessments. That’s at least $2,750 before surcharges. The one break: the judge may suspend all but fourteen days of jail if the person equips their vehicle with a certified ignition interlock device for twelve months.
Federal trucking rules. 49 CFR 392.5 prohibits drinking within four hours before going on duty. It also bars a driver from being on duty while possessing beer, wine or liquor unless it’s manifested and transported as part of a shipment. In other words, a can of hard tea in the cup holder breaks the rule even if nobody drank it. A violation puts the driver “out-of-service immediately for a period of 24 hours.” www.law.cornell.edu
The CDL. For a first conviction, the federal disqualification table sets a one-year disqualification if the driver was in a commercial vehicle, 3 years if the truck was hauling hazmat, and a lifetime ban on a second conviction. The rule also reaches a driver’s personal vehicle: a first alcohol-impairment conviction in a non-commercial vehicle carries a 1-year CMV disqualification, the same as in a CMV. At 0.301, this driver is facing a long time away from commercial driving, possibly permanently. www.law.cornell.edu
The Impound Bill Goes to Someone Else
Arizona’s impound law requires removal when an officer has probable cause to arrest the driver under § 28-1382, and the vehicle stays impounded for 20 days. The statute also says that “An insurance company does not have a duty to pay any benefits for charges or fees for immobilization or impoundment.” www.azleg.gov
If the truck belongs to a carrier or a leasing company, the cost lands on them. That means:
- A tractor sitting idle for nearly three weeks
- A trailer whose freight still has to reach its customer
- Storage fees that keep adding up every day
The owner can contest the impound at a poststorage hearing. The bigger bill arrives later: an alcohol violation on the carrier’s safety record, which its insurance underwriter will find at the next renewal. A driver like this one is a hiring-and-supervision problem, and underwriters price those. www.azleg.gov
About That Citizen Intervention
Credit where it’s due: nobody got hurt, and a semi driven by someone at 0.301 stopped moving. Still, nobody should treat this as a how-to. Walking up to an impaired stranger in a running tractor-trailer means betting that the truck won’t lurch forward and the driver won’t fight back. This caller won that bet.
Stuck behind a semi that keeps drifting over the lane markers? Here’s what to tell dispatch:
- Call early. Don’t wait to see whether it gets worse.
- Give the mile marker and direction of travel.
- Note the trailer markings.
- Read off the USDOT number on the cab door. It links the truck to a specific carrier in FMCSA’s public records, so the company can’t avoid responsibility.
- Keep your distance. A loaded semi weighs far more than your car, and if it’s out of control, being close to it is dangerous.
A stranger pulled a drunk driver out of a running semi and took his keys. Would you have walked up to that cab, or called it in from 200 yards back?
