Published May 8, 2026
## CDL DUI in Arkansas
Commercial driver's license (CDL) holders face SIGNIFICANTLY stricter DUI rules than regular drivers — and the consequences can end commercial driving careers permanently.
## Lower BAC limit — 0.04%
**Federal Motor Carrier Safety Regulations (FMCSR)** — applies in ALL states:
- **0.04% BAC limit** (half of 0.08% standard)
- Applies when **operating commercial motor vehicle (CMV)**
- Some states stricter (0.02% or zero tolerance)
**Important — applies to:**
- Class A, B, or C CDL holders driving CMV
- Vehicles with GVWR 26,001+ lbs
- Vehicles transporting 16+ passengers (including driver)
- Hazmat vehicles regardless of size
- Vehicles requiring CDL endorsement
## CDL disqualification rules
**First DUI in CMV (any BAC over 0.04%):**
- **1-year CDL disqualification**
- **3-year disqualification if hauling hazmat**
- Cannot drive any CMV during disqualification
**First DUI in personal vehicle (BAC 0.08%+ or impaired):**
- **1-year CDL disqualification (still!)**
- Federal regs apply regardless of vehicle
- Even off-duty DUI ends commercial driving
**Second DUI (any vehicle, any time):**
- **LIFETIME CDL disqualification**
- Some states allow reinstatement after 10 years; many don't
- Career-ending in most cases
**Refusing chemical test:**
- Same consequences as DUI conviction
- 1-year disqualification (first refusal)
- Lifetime disqualification (second)
**Other CDL-disqualifying offenses (also count toward lifetime ban):**
- Driving CMV with revoked / suspended / canceled CDL
- Causing fatality through negligent operation of CMV
- Felony involving CMV
- Drug trafficking using CMV (lifetime, no reinstatement)
- Leaving scene of CMV accident
## No "masking"
Federal law (49 CFR § 384) **prohibits states from "masking" CDL DUIs:**
- No diversion programs allowed
- No deferred adjudication
- No expungement
- No reduced charges ("wet reckless")
- No bargaining around disqualification
Even if regular drivers can plea-bargain to reduce charges, CDL holders cannot — the conviction follows.
## Implied consent for CDL holders
**Stricter than regular drivers:**
- Mere refusal triggers automatic disqualification
- Some states require ANY testing on CDL holders during traffic stops
- Reasonable suspicion (not probable cause) often sufficient
## DUI in personal vehicle still disqualifies CDL
**This catches many drivers off-guard:**
- Sunday afternoon DUI in personal car?
- Same 1-year CDL disqualification as on-duty DUI
- Federal regulation, not optional for state
- Even out-of-state DUIs count
- Even before you got your CDL counts (depending on state)
**Most CDL holders don't know this until it happens.**
## Out-of-CDL-state convictions
**Driver License Compact + CDLIS:**
- All states share CDL data
- DUI in any state reported to home state
- Home state imposes disqualification
- Cannot escape by switching states
## Employment consequences
**Beyond legal consequences:**
- **Federal Motor Carrier database** records DUI
- Trucking companies WILL find it in PSP / DAC reports
- Most companies won't hire CDL-DUI drivers (insurance issues)
- Insurance becomes prohibitively expensive
- Some companies have "never DUI" policies
- HazMat / passenger / school bus endorsements typically forfeited
**Industries that may still hire (depending on state, time elapsed):**
- Smaller local carriers
- Construction / dump trucks
- Some agricultural operations
- Self-employed / owner-operator (insurance challenge)
## DOT drug testing implications
**Drug DUI = positive drug test:**
- Treated as DOT testing failure
- Cannot return to safety-sensitive function until SAP (Substance Abuse Professional) program complete
- Mandatory treatment + follow-up testing for 1-5 years
- Career impact often years long
## Defenses to CDL DUI
**Same as regular DUI defenses, but stricter standards:**
- **Stop legality** — was traffic stop justified?
- **Field sobriety tests** — properly administered?
- **Breath test calibration / maintenance**
- **Blood test chain of custody**
- **0.04% margin of error** challenges
- **Operator status** — were you actually driving?
- **CMV vs personal vehicle** classifications
- **Procedural errors** in arrest / testing
**Specific to CDL:**
- Was vehicle actually a CMV when stopped?
- Was driver "on duty" status established?
- Was driver actually CDL holder at time?
## Employment / company-vehicle issues
**Employer-owned CMV:**
- Company has stake in defense
- Insurance issues for company
- Federal record visible to all carriers
- DOT investigation possible
**Self-employed / owner-operator:**
- Direct hit on livelihood
- Insurance becomes very expensive
- May lose authority / operating credentials
- Personal financial impact severe
## What CDL holders should do after DUI
**1. Hire experienced DUI / CDL attorney IMMEDIATELY:**
- Many DUI lawyers don't understand CDL nuances
- Specifically ask about CDL experience
- 0.04% BAC challenges differ from 0.08%
- Federal regulations interplay with state law
**2. Don't accept any plea bargain:**
- "Wet reckless" still disqualifies CDL
- Diversion programs prohibited for CDL holders
- Conviction is conviction
- Trial may be only option
**3. Notify employer carefully:**
- May have legal duty to disclose
- Consult attorney before disclosing
- Employer can fire upon learning
- Some companies suspend pending outcome
**4. Plan financially:**
- 1-year career interruption likely
- Lifetime disqualification permanent in most states
- Consider career transition planning
**5. Address underlying issues:**
- DUI school / treatment likely required
- Better to do voluntarily and document
- Helps with sentencing / future reinstatement
## Reinstatement (if available)
**1-year disqualification:**
- Wait full year (no early reinstatement)
- Complete state requirements (DUI school, etc.)
- Pay reinstatement fees
- Pass tests / medical exam if required
- Insurance challenge
**Lifetime disqualification:**
- Most states: NEVER reinstatable
- Some states: 10+ year wait + rehabilitation petition
- Federal regs allow but don't require state reinstatement
## What you should do
