Many Arkansans use the terms DWI and DUI interchangeably — but under Arkansas law, they are not the same thing.
The difference matters because it affects:
- The age of the driver
- The BAC threshold required for charges
- The burden of proof
- The penalties
- How the case is handled in court
- Long-term consequences
Here’s a clear breakdown of DWI vs. DUI in Arkansas so you know exactly what these charges mean.
Important to Know
Under Arkansas Code § 5-65-107, DWI charges cannot be plea-bargained down to a lesser offense like reckless driving. That doesn’t mean DWI cases can’t be dismissed — they can — but the path to a better outcome is through factual and constitutional challenges, not negotiation. The same is true for underage DUI under § 5-65-303.
1. What Is DWI in Arkansas?
DWI = Driving While Intoxicated
Under Arkansas Code § 5-65-103, DWI applies to drivers of any age who are impaired by:
- Alcohol
- Drugs (illegal or prescription)
- A combination of substances
You can be charged with DWI if:
- Your blood alcohol concentration (BAC) is 0.08 or higher, OR
- The State proves you were intoxicated — meaning your reactions, motor skills, or judgment were substantially altered — even with a BAC below 0.08, OR
- The impairment was caused by drugs (including legally prescribed medications)
Arkansas DWI applies even if the vehicle was not moving. The statute applies to anyone in “actual physical control” of a vehicle — which courts have interpreted broadly to include sitting in the driver’s seat with keys nearby.
2. What Is DUI in Arkansas?
DUI = Driving Under the Influence — but in Arkansas, this charge applies only to drivers under 21.
Arkansas uses a “zero tolerance” policy for underage drivers. Under § 5-65-303, an underage driver commits DUI if they operate (or are in physical control of) a motor vehicle while:
- Their BAC is 0.02% or higher but less than 0.08%, OR
- They are “under the influence” — meaning their normal faculties are affected by alcohol or drugs even slightly
Underage DUI BAC Range
0.02% to <0.08%
Approximately one drink for many people
If an underage driver’s BAC is 0.08% or higher, they are charged with regular DWI — not the lesser DUI. Underage drivers can also face standard DWI charges if the State proves intoxication regardless of BAC.
3. Key Differences at a Glance
| Factor | DWI | DUI (Under 21) |
|---|---|---|
| Who can be charged? | Drivers of any age | Only drivers under 21 |
| BAC level | 0.08+ or proven intoxication | 0.02 to less than 0.08 |
| Statute | § 5-65-103 | § 5-65-303 |
| Proof of impairment required? | Yes (or BAC 0.08+) | No — BAC alone is enough |
| Criminal classification | Misdemeanor (felony for 4th+ within 10 years) | Unclassified misdemeanor |
| Jail time? | Yes — minimum 24 hours for first offense | Generally no for first offense |
| Plea bargain to lesser offense? | Prohibited by § 5-65-107 | Prohibited |
| License suspension? | 6 months (1st), 24 months (2nd), 30 months (3rd) | 90 days (1st), 1 year (2nd), 3 years or until 21 (3rd) |
4. Penalties for DUI (Under 21)
A DUI under § 5-65-303 is an unclassified misdemeanor, but the penalties become progressively more severe with each offense:
| Offense | Fine | License Suspension | Other |
|---|---|---|---|
| First | $100 – $500 | 90 days | Alcohol education course |
| Second | $200 – $1,000 | 1 year | 30+ days community service, alcohol education |
| Third | $500 – $2,000 | 3 years or until age 21 (whichever is longer) | 60+ days community service, alcohol education |
Beyond the statutory penalties, a DUI conviction can have substantial collateral consequences for someone under 21:
- Long-term auto insurance increases
- Loss of college scholarships or financial aid
- Disciplinary action under student conduct codes (University of Arkansas, Arkansas State, UCA, and others have specific policies)
- Disqualification from certain professional licenses
- Background-check visibility for years before any sealing
5. Penalties for DWI (Standard Adult Charge)
DWI penalties under § 5-65-103 are significantly more severe than DUI, even for a first offense:
| Offense (within 10 years) | Jail Range | Fine | License Suspension |
|---|---|---|---|
| First | 24 hours – 1 year | $150 – $1,000 | 6 months |
| Second | 7 days – 1 year | $400 – $3,000 | 24 months |
| Third | 90 days – 1 year | $900 – $5,000 | 30 months |
| Fourth+ (Felony) | 1 – 6 years prison | $900 – $5,000 | 4 years |
Higher minimum jail times apply if a passenger under 16 was in the vehicle (7 days for first offense, 30 days for second, 120 days for third). For a more detailed breakdown, see our DWI penalties guide.
6. Can a DUI or DWI Be Reduced or Dismissed?
Arkansas law (§ 5-65-107) prohibits “pleading down” a DWI to a lesser offense like reckless driving. The same approach applies to underage DUI charges. That doesn’t mean these cases can’t be defeated — it means the path is through factual and constitutional challenges, not plea negotiation to a lesser offense.
Common defenses include:
Improper Stop
If the officer lacked reasonable suspicion to pull you over, everything that follows can be suppressed.
Faulty Breath Testing
Intoxilyzer calibration errors, operator certification issues, and improper observation periods are common.
Chemical Test Issues
Blood draw chain-of-custody, lab contamination, and warrant defects can invalidate test results.
Rising BAC Defense
BAC at the time of testing may have been higher than at the time of driving — the State must prove BAC at the wheel.
Field Sobriety Test Errors
Officers frequently administer FSTs incorrectly. Body-cam often contradicts the officer’s report.
Constitutional Challenges
Miranda violations, illegal searches, and warrantless blood draws under Birchfield v. North Dakota can lead to suppression.
Don’t forget the 7-day rule — Arkansas drivers have only 7 calendar days from arrest to request an administrative hearing to challenge license suspension. Missing this deadline forfeits the right to fight it.
Frequently Asked Questions
Can a 19-year-old get charged with regular DWI instead of underage DUI?
Yes. If the underage driver’s BAC is 0.08% or higher, or if they’re “intoxicated” (substantially impaired), they’re charged with regular DWI under § 5-65-103 — not the lesser DUI under § 5-65-303. An underage driver with a BAC of, say, 0.10% would face the harsher adult DWI charges, including possible jail time.
Does refusing the breath test help?
Under the implied consent law (§ 5-65-202), refusing a chemical test triggers automatic license suspension and can be used as evidence at trial. Refusal does not prevent prosecution. For some drivers, refusal makes the case worse, not better.
Are field sobriety tests required?
No. Field sobriety tests (walk-and-turn, one-leg stand, horizontal gaze nystagmus) are voluntary. You may decline without legal penalty — though refusal may be noted by the officer. The roadside portable breath test (PBT) is also generally voluntary, although the official chemical test at the station is covered by implied consent.
Is there a difference between DUI and DWI for boating?
Yes. Arkansas applies both standards to boating. § 5-65-303 covers underage Boating Under the Influence (BUI) for those under 21 with a BAC between 0.02% and less than 0.08%. The adult standard applies to operators 21+ at 0.08% or higher.
Can a DWI conviction be expunged in Arkansas?
Adult DWI convictions can be sealed after the “lookback period” of 10 years.
Does an out-of-state DUI/DWI count as a prior in Arkansas?
Generally yes. Arkansas courts can consider out-of-state DUI/DWI convictions as prior offenses for enhancement purposes, depending on whether the out-of-state offense is substantially similar to Arkansas’s statute. This means a DWI in Texas or Tennessee can make your “first” Arkansas DWI count as a second.
What if the test result is right at 0.08?
Borderline BAC results can sometimes be effectively challenged. Breathalyzer machines have margins of error, and the State must prove BAC at the time of driving — not at the time of testing. Time delays between driving and testing, calibration issues, and observation period violations are all potentially relevant. These are technical defenses where attorney experience makes a real difference.
The Bottom Line
DWI and DUI are not the same in Arkansas:
- DWI applies to drivers of any age and requires a BAC of 0.08+ or proof of intoxication. Penalties include jail time even for a first offense.
- DUI applies only to drivers under 21 and requires only a BAC of 0.02 to less than 0.08 — no proof of impairment is needed.
Both charges can significantly impact your future — but both can be successfully defended. Because Arkansas prohibits “pleading down” these charges to lesser offenses, the route to a better outcome is through factual and procedural challenges, not negotiation.
